I think should be encouraged.  We're eagerly awaiting the ability to run
FreeBSD in AWS in something other than t1.micro or cluster compute
instances.  Should we keep holding out hope, or will AWS make HVM available
for all instance types before this happens?

Err... my AMIs run on all EC2 instance types.  On some you have to pay the
Windows rate, that's all.

The Windoze tax is unacceptable for a number of reasons - the primary
reason is that I'm not running Windows.  I don't think the licensing scheme
is unfair for those actually running Windows, mind you.

At the AWS Summit, an assertion was made that HVM support might be coming
soon for all instance types for *NIX OSes.  I hope that's true.

Right, it's definitely annoying having to pay more -- I just wanted to point out
that the ability does exist, if you're willing to pay the price.

Was it indeed?  I must not have been present for that... it certainly would be
good news.  Certainly all the new instance types they've released in the past
few years have had UNIX HVM support.

Is this something we should try to put on the Xen.org blog?

Cool! :-)

I think it definitely should... Whoever is up to write a blog post about
it, please, get in touch to me.

Soon we'll have the new mailing lists and all the stuff, but for now,
just drop me a line, and I can put the post in the pipeline.

Regards,
Dario

I built a XENHVM kernel with this code on EC2, and it hanged after

With a XENHVM kernel from FreeBSD HEAD the next line after that is

Any ideas?

Hello Colin,

Thanks for testing this on EC2, could you post the full dmesg? So I can
see the hypervisor version and if the PV timer is loaded or not.

Roger.

Here's what I get on a cc2.8xlarge with boot_verbose=YES:

I've pushed a new branch to my repository, pvhvm_v7 that should work,
there was a bug with PCI event channel interrupt set up. I've tested
with 3.4 and seems OK, but of course it doesn't support the vector
callback injection.

That seems to work.  dmesg is attached.  Are there any particular tests
you'd like me to run?

If anyone else wants to play with this, you can launch ami-e75c358e in the
EC2 us-east-1 region.

I have not tested ZFS, that might be a good one. If you are running this
on Xen 3.4 the behaviour should be the same as without this patches, so
there shouldn't be many differences.

If you could try that on Xen 4.0 at least (if I remember correctly
that's when the vector callback was introduced), you should see the PV
timer getting attached, and a performance increase.

I don't use ZFS personally, so I'm not sure exactly what tests to run on it;
hopefully someone else can take care of that.

Testing on a cr1.8xlarge EC2 instance, I get Xen 4.2, but it ends up with
a panic -- console output below.  I can get a backtrace and possibly even
a dump if those would help.

Hello Colin,

Thanks for the test, I've been using Xen 4.2 (and 4.3) without problems 
so far. By looking at the Xen code, the only reason the timer setup 
could return -22 (EINVAL), is that we try to set the timer for a 
different vCPU than the one we are running on.

I've been able to boot a 32 vCPU DomU on my 8way box using Xen 4.2.1 
(using both qemu-xen and qemu-xen-traditional device models), so I'm 
unsure if this could be due to some patch Amazon applies to Xen. Could 
you try the following patch and post the error message? I would like to 
see if the cpuid reported by kdb and the vCPU that we are trying to set 
the timer are the same.

Booting...

Thanks for the test, this is what I expected. I'm a little bit out of
ideas since I'm not able to reproduce this on upstream Xen 4.2. Without
knowing what's happening inside the hypervisor it's hard to tell what's
wrong. It would be interesting to try if the same happens with a Linux
PVHVM (not PV) running on the same instance type.

Hello Matt,

Colin has found an issue on the FreeBSD PVHVM port that I haven't been
able to reproduce using open source Xen, even when using the same
version as the one reported by EC2. Is there anyway you could provide
some help debugging this? Without seeing the Xen code that causes
VCPUOP_set_singleshot_timer to return EINVAL it is quite hard to figure
out what's happening inside the hypervisor.

Thanks, Roger.

Hi Roger,

VCPUOP_set_singleshot_timer returns -EINVAL when:

1) the specified vCPU ID is out of range (<0 or >MAX_VIRT_CPUS)
2) the specified vCPU ID doesn't match the running vCPU.

It seems that there is a confusion between the logical vCPU ID and the
local APIC physical ID.

I added some debugging to case 2):

Thanks Matt!  Looks like we need to pass our acpi_id to the Xen hypercall
instead of our cpuid.

Roger, changing the line
	int cpu = PCPU_GET(cpuid);
to
	int cpu = PCPU_GET(acpi_id);
in xentimer_et_start and xentimer_et_stop fixes this panic and gets me
slightly further; the following lines are now added to the console output
prior to the system appearing to hang:

and then the userland boot process; have you made any bug fixes after
your pvhvm_v7 which would explain why tasting disks was hanging?

Hello,

Thanks Matt and Colin for the testing and help! I've pushed yet another
version, now it's branch pvhvm_v12, which I *think* should solve the
issues with cpuid != acpi_id:

http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=shortlog;h=refs/heads/pvhvm_v12

Since I'm not able to reproduce the cpuid != acpi_id case, could you
give it a try and report the results?

I'm not sure I follow, did you found a regression from previous
branches? i.e. it used to work with branch pvhvm_v6 and not pvhvm_v7?

Colin was saying that his local change only moved the boot process a
bit farther for cr1.8xlarge. Perhaps some of the other changes you
made in the latest pvhvm_v12 branch will get the VM all the way up.

Konrad,

Might this same problem be related to the issue you saw doing PVHVM VCPU
hotplug which you mentioned the other day?

In general for HVM I suppose there isn't a strict relationship between
the CPU number the kernel chooses for a CPU (which is somewhat
arbitrarily up to the kernel) and the hypervisors VCPU number (which is
exposed via the virtual APIC ID).

Right. To troubleshoot this I added some instrumentation to make sure
that the xen_vcpuop_set_mode function was using the right vCPU number.

Initially it got it from smp_processor_id(), which gets it from the
APIC ID (at least that is what it looks like). But perhaps it was not.
I can't seem to reproduce the issue anymore :-(

Is smp_processor_id() always from APIC ID? For x86 I see:
        raw_smp_processor_id()
        stack_smp_processor_id()
        safe_smp_processor_id()
        smp_processor_id()
        logical_smp_processor_id()
        hard_smp_processor_id()
also things like cpu_physical_id(). I'd have to assume they aren't all
equivalent ;-)

> I can't seem to reproduce the issue anymore :-(

Well, that sounds like a good thing to me ;-)

The CPU enumeration should follow the ACPI ID order in MADT (or
MP-table), right?  The local APIC ID (returned by cpuid
EAX=0000_0001h => EBX bits 31:24) shouldn't be used for
enumeration. Under Xen, the LAPIC ID is hardcoded to vCPU idx * 2:

void hvm_cpuid(unsigned int input, unsigned int *eax, unsigned int *ebx,
[...]
     case 0x1:
         /* Fix up VLAPIC details. */
         *ebx &= 0x00FFFFFFu;
         *ebx |= (v->vcpu_id * 2) << 24;
[...]
     case 0xb:
         /* Fix the x2APIC identifier. */
         *edx = v->vcpu_id * 2;
         break;

This isn't the way it works on some of our EC2 instances.  On our high
performance instance types, we provide x2APIC IDs that distinguish
threads, cores and sockets to provide the guest OS with CPU topology
information. The OS and applications can use CPUID EAX=0000_000Bh,
ECX=level (HT=0, Core=1, Socket=2) => EAX bits 4:0 to determine the
topology.

You mean the guest's enumeration? I'd have thought that was entirely up
to the guest. Using the APIC ID might be a reasonable implementation but
there are surely others (e.g. collapsing sparse LAPIC IDs into
contiguous cpu ids, using the top bits for NUMA node, etc etc).

Hrm, that does beg the question of how an HVM guest is supposed to
determine what Xen's idea of the VCPU number is for a given CPU.

I can't see anything which reverses that * 2 on the vcpu_op path and I
don't suppose you implemented the inverse of your scheme.

On bare metal x86 Linux, the kernel enumerates CPUs based on an order
defined by the BIOS. Typically this means that all the cores are
enumerated first, followed by logical processors (HT/SMT). For Linux,
maxcpus=N/2 should disable HT on systems that enumerate processors in
the recommended order. Some history:

The virtual BIOS provides both ACPI tables and a legacy MP-table that
gives the LAPIC id mapping. The guest could infer the Xen vCPU ID from
a processor's position in these tables. Or we could add a VCPUOP that
an enlightened guest could use to get the information more directly.

One question: why does a hypercall take a parameter that only has one
valid value? That value can be determined by looking at the current
running vCPU.

The *2 is just for assigning the LAPIC ID, and I'm pretty sure that
Linux is assigning processor IDs sequentially at ACPI parse time.

How the guest chooses to enumerate the CPUs is not terribly relevant so
long as the Xen specific code for that OS knows how to invert that
mapping to get at the underlying ABI which determines Xen's VCPUID for a
CPU.

I think I was wrong to focus on the guest enumeration scheme before,
what actually matters is where in our ABI we expose the VCPUID, which
isn't at all clear to me.

Do we consider the ordering given in any of those tables to be an HVM
guest ABI? What about the lapic_id == 2*vcpuid -- is that multiplication
factor part of the ABI (i.e. is the guest expected to pass lapic_id/2 to
vcpuop)?

I'm hoping that there is some existing interface which I simply don't
know about, but yes this could be the answer if such a thing doesn't
exist.

The generic prototype is:
        vcpu_op(int cmd, int vcpuid, void *extra_args)
Some cmds can act on any vcpuid and others can only act on the current
vcpu. In an ideal world we would have had VCPUID_SELF or something but
its a bit late for that.

That probably doesn't matter, what matters is the Xen specific parts of
the kernel's ability to reverse that assignment to get at the underlying
APIC ID, assuming that is actually an ABI from which we can infer the
VCPU ID...

I strongly prefer the order in the BIOS tables, *not* the
lapic_id = 2*vcpuid formula. Once I've done some libxl work, I'll be
proposing a patch that makes the LAPIC / x2APIC IDs configurable,
and that will break this assumption.

I don't know of one that provide the information explicitly. It might
be easiest to provide this as a hypervisor CPUID leaf so it can be
used in early boot.

Indeed. This seems to be loosely defined so far, and easy to get wrong
as happened with this FreeBSD work.

I am a bit confused by 'I strongly prefer the order in the BIOS tables'.
The way I understand it - Linux setup up the vCPUs based on the LAPIC
which are created by the hvmloader. There are no hypercalls or any
lapic_id =2*vcpuid formule in the Linux kernel. I presume what you meant
by the lapic_id = 2 * vcpuid is more of this:

144     for ( i = 0; i < nr_processor_objects; i++ )                                
145     {                                                                           
146         memset(lapic, 0, sizeof(*lapic));                                       
147         lapic->type    = ACPI_PROCESSOR_LOCAL_APIC;                             
148         lapic->length  = sizeof(*lapic);                                        
149         /* Processor ID must match processor-object IDs in the DSDT. */         
150         lapic->acpi_processor_id = i;                                           
151         lapic->apic_id = LAPIC_ID(i);                        

Which sets this up.

So .. assuming this was thought out, why are we starting on vCPUs
that don't match to this? That seems like a bug? (Note, this is 
with maxvcpus=32, vcpus=1 and the starting of a VCPU1 actually
ended up starting at VCPU4?!).

I think all of this can be sorted out if the hvmloader sets the
LAPIC CPU == VCPU ID properly. So perhaps a better question is - why
is it not setup properly nowadays? If the formal is baked in for
the PVHVM guests, somewhere the formula is not being evaluated properly?

The new hypercall to figure this out could be used, but that wouldn't
explain why we are failing to start on the correct VCPU?

Right, all of the LAPIC information is provided to the guest OS via
the MADT. I believe what I'm observing is that Linux and Windows use
the order of entries to enumerate processors in the system.

What we typically see on bare metal Intel systems is something like
this (example system has 16 cores with HT):

All of the "cores"...
[    0.000000] ACPI: Local APIC address 0xfee00000
[    0.000000] ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x02] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x02] lapic_id[0x04] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x03] lapic_id[0x06] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x04] lapic_id[0x08] enabled)
...

Followed by all of the "threads"...
[    0.000000] ACPI: LAPIC (acpi_id[0x10] lapic_id[0x01] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x11] lapic_id[0x03] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x12] lapic_id[0x05] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x13] lapic_id[0x07] enabled)
[    0.000000] ACPI: LAPIC (acpi_id[0x14] lapic_id[0x09] enabled)

Since Xen hard codes the LAPIC ID (and x2APIC ID) to 0, 2, 4, 6, 8,
etc. (vCPUID * 2), everything looks like a core.

I'm lost. What?

No, that's not the right answer. Or, at least, not completely. Right
now Xen provides the same ID for both the LAPIC and x2APIC. In order
for cpu topology discovery to work, the x2APIC needs to follow a
particular structure. See the Intel whitepaper on processor topology
enumeration:
  http://software.intel.com/sites/default/files/m/d/4/1/d/8/Kuo_CpuTopology_rc1.rh1.final.pdf

The "LAPIC ID = 2 * vCPUID" formula is not baked into any OS that I
know of, and it shouldn't be. It should all be discovered via
firmware/BIOS tables. The enumeration order in the tables should,
under best practices, match the logical processor ID assignment in the
OS.

I didn't follow the jump here. Can you provide an example?

Nice explanation. However, I was under impression that right now we

Hmm?

OK, got it.

[   84.619508] smpboot: Booting Node 0 Processor 1 APIC 0x8

So it seems like, in this case:

int __cpuinit native_cpu_up(unsigned int cpu)
{
        int apicid = apic->cpu_present_to_apicid(cpu);

apic->cpu_present_to_apicid(1) returned 8 instead of 2.

All of that should have been set up correctly ahead of time by
generic_processor_info() for all possible CPUs. Do you have the full
boot log?

OK, so generic_processor_info() is not called for disabled processors,
so it must happen at processor UP time.

Can you boot with "acpi.debug_layer=0x20000000 acpi.debug_level=0x4"?

If I can reproduce it again - absolutly. Right now the race seems to have
gone away and the APIC id is 0x02 (the right value) instead of 0x08.

I discussed this with Matt over IRC, but the analysis was that the APIC
ID is wrong. Instead of using APIC 0x02 for CPU1, it ended up using APIC 0x08
(which is for CPU4). And that triggered the xen_vcpuop_set_mode to fail
(as the hypervisor would say - you are running on CPU4, not CPU1, return
-ENODEV) and we hit the BUG_ON() in the Linux.

Chuck Anderson (CC-ed here) discovered that he was hitting this as well
and realized that if he was using the QEMU with these three patches:

169b8fa piix4acpi, xen, hotplug: Fix race with ACPI AML code and hotplug.
309149c piix4acpi, xen: Clarify that the qemu_set_irq calls just do an IRQ pulse.
82b10d1 piix4acpi, xen, vcpu hotplug: Split the notification from the changes.

the problem would go away. We did not go any deeper to figure out the culprit.

My money is on the AML code modifying the MADT and while it is executing
another ACPI GSI is triggered (the old code would trigger it for every CPU
being hot-plugged) and as the Linux ACPI AML interpreter reads the MADT and writes
out the newly updated MADT another of the CPUs ends up reading the MADT as well -
but ends up with the data being bogus as the AML interpreter did not finish
and got garbage.

Either way, the resolution is if you see this - the fix is to update the
qemu to have those patches.

Thanks Chuck for digging in this and finding the clues.


P.S.
I don't know how SeaBIOS does the CPU hotplug, but it might be worth looking
at that too at some point.

Oh, sure, more changes where needed in order to get it to work, like
using acpi_id to map the vcpu_info and perform the cpu bindings.

Ah, that explains it.  I looked at timer.c for other places where that
change was needed but it didn't occur to me that the same problem would
exist in other parts of the tree.

Done, ami-95177dfc in us-east-1.

This is now booting successfully on cr1.8xlarge; are there any other instance
types I should test?  I don't know which Xen versions you have deployed across
the entire fleet.

Nice! The other interesting instance types for problems like this are
cc1.4xlarge, cg1.4xlarge and cc2.8xlarge.

I've tried on all three of those and everything seems good -- but I'm only
seeing Xen 3.4 on those instance types, so we're not really testing anything
interesting there.

I'll resist asking whether there will be Xen 4.x anywhere else in EC2 in the
near future since I've had enough of a taste of Amazon NDAs to know that I
almost certainly wouldn't get an answer... ;-)

I tried on my Linux box to do this:

As I thought it would compile the same way you can compile NetBSD - that is
even on non-BSD distros. Is that not the case? Should I only do this under
a FreeBSD guest?

I have never tried to run the FreeBSD build system under something
different than FreeBSD, also keep in mind that installkernel will place
a bunch of FreeBSD files on your Linux box if you manage to run it. The
error itself can probably be fixed by installing and using BSD make
(bmake), but anyway you need a FreeBSD HVM DomU in order to test the
kernel, so why not do the compilation on it?

Oh, sure. Just thought that the NetBSD method (which also allows one
to build the kernel and the iso) was the same on FreeBSd. Will of course
install first the HVM domU and do it again.

I've just been able to install it on a VPS using the latest pvhvm_v9 branch.
This is good news, because the system I had before actually had trouble with the HVM kernel from 9.1 [0].

I'm going to leave this running for a while and do some more tests on it.

You mention on that page that it is easier to install on 10.0-CURRENT snapshots.
What are the issues with installing this on 9.1? Is it possible?

I don't think it is recommended to use a HEAD (10) kernel with a 9.1
userland. You can always install a 9.1 and then do a full update with
the source on my repository.

Actually in FreeBSD, it is possible to run an older userland on a newer
kernel,
and a lot of effort is spent in preserving this type of backwards
compatibility.
So a 9.1 userland with a 10 kernel will work.
However, running a newer userland on an older kernel is not guaranteed to
work.
So running a 10 userland with a 9.1 kernel will most likely not work.

However, since you guys are doing very cutting edge stuff with 10-CURRENT,
it is better that you do not waste time with 9.1.

I recommend you start with a 10.0 CURRENT snapshot ISO and go from there.
I am going through a similar setup exercise with a Google Summer of Code
student
where he needs to have a latest CURRENT system running in a VM.

I wrote this blog post:

http://blogs.freebsdish.org/rodrigc/2013/05/24/setting-up-a-vm-for-doing-gsoc-work/

for the steps how to do it.  You can follow those steps to get bootstrapped
with a working environment if it helps you out.

Good luck.

Any chance this will be backported to 9.X or 9-STABLE at least ??

I wrote a blog post specifically for installing 10-CURRENT from a snapshot
ISO and getting bootstrapped
from there, to help the Google Summer of Code Student that I am mentoring.
What specifically do you want to be backported to 9-STABLE?

Yes Ive seen the post, however we have a hard requirement for 9-STABLE for
some development work we are
currently involved in. And I would prefer not to move our current
infrastructure for development to CURRENT.
A major portion of our development environment is based on XEN for testing
and development.
Therefor we realize PVHVM is a work in progress, and we have built some
 VMs from it, they run exceptionally
well, However our build environments refuse to build 9-STABLE on CURRENT
PVHVM, or 10-CURRENT.
Lastly Im sure theres a ton of users who would like to see this in 9.x or
9-STABLE

OK, I misunderstood you since you responded in the thread and quoted some
of my post.
My blog post has nothing relevant to Xen and PVHM, and is specific to
setting up
a Google Summer of Code student on a 10-CURRENT environment.  The FreeBSD
Xen
and PVHM developers will need to provide the details about their plans to
merge their changes to the 9-STABLE branch.....
that's something which I am not familiar with.

Can you recheck this on stock HEAD?

Re: FreeBSD PVHVM call for testing

[Roger Pau Monné]

Hello,

I've pushed a new branch, pvhvm_v10 that contains a PV IPI
implementation for both amd64 and i386. I've also updated the wiki to
point to the pvhvm_v10 branch:

http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=shortlog;h=refs/heads/pvhvm_v10

I've updated my tree to latest HEAD, so now branch pvhvm_v10 is on top
of this commit:

commit b44da0fb82647f2cfb06f65a6695c7e36c98828c
Author: gber <gber@FreeBSD.org>
Date:   Thu May 23 12:24:46 2013 +0000

    Rework and organize pmap_enter_locked() function.

    pmap_enter_locked() implementation was very ambiguous and confusing.
    Rearrange it so that each part of the mapping creation is separated.
    Avoid walking through the redundant conditions.
    Extract vector_page specific PTE setup from normal PTE setting.

Thanks for the testing, Roger.

Hey Guys,

Huge KUDOS to some great work, Ive gotten 4 VMs booting from zfsonroot with
the rev_9 finally under XCP 1.6
after getting through removal of the cdrom device from VMs, they are booted
and running supremely nice now.
IO for zfs filesystems is much better inside the VMs now, even with 4mb
compared to what it was. This is a huge
move forward and personally I just wanted to say thanks for this and all
the work you put into it. The VMs appear quite stable for me, and are
pleasantly responsive with low mem on zpools. Great job and again.....
Thanks. Keep up the great effort.

Hi,

I've just successfully run FreeBSD 9.1 based guest with 'pvhvm_v8' based kernel under Xen 4.2.2.

So I couldn't confirm any issue with the kernel both on Xen 3.4.4 and 4.2.2.
Nice Job.

I feel a bit stupid to ask this, but how I install 'gmake'? Doing 'pkg_add -r gmake'
tells me there is no package (perhaps I am using a too modern version of FreeBSD
(FreeBSD-10.0-CURRENT-amd64-20130512-r250582-release.iso)?

The Wiki mentions how to install git but that fails b/c it can't find gmake.

on 10-CURRENT you need to use pkg or build from ports/devel/gmake

Did you install the ports tree during the installation? If so I've
always successfully installed git using:

# whereis git
# cd <output of above command>
# make install

Maybe the ISO you picked as a broken ports snapshot?

For 10.0-CURRENT, not all the packages are available yet from the main
FreeBSD.org ftp site.
I am going through a similar setup issue with someone who has signed up for
Google Summer of Code,
and I need him to use close to the latest 10.0-CURRENT and have a usable
system.

I wrote this blog post for the student:
http://blogs.freebsdish.org/rodrigc/2013/05/24/setting-up-a-vm-for-doing-gsoc-work/

You may wish to follow those steps to configure your system to download
packages from
one of the 3rd party pkg mirrors, and then use the "pkg" command to install
gmake and whatever other packages you need.
Outback Dingo has mentioned using "pkg" command for installing packages in
10-CURRENT, and that is
what I am instructing my GSoC to do.

Good luck.

I've been running a VM with this kernel for about a week now. It ran fine, until about 3:30 in the morning. The only thing I can see is the following cryptic messages in /var/log/messages, followed by a reboot of the system.

Hello Jeroen,

So it looks like the system rebooted (but it was not a crash or a
sporadic reboot? the kernel seems to be aware of the reboot request). It
would be interesting if you could provide the output of the serial
console when this happens, that might be helpful. Did you enable
xenconsoled logging?

Also, could you provide more info about your system, Xen version, what
workload was the DomU running, Dom0 kernel version?

Unfortunately I did not.

There was no one logged in at the time of the reboot according to the last log.
I did do some sysbench tests during the day, but that was way before it rebooted. The only thing that could be running during that time was daily periodic.

This VM is on a public IP indeed, and SSH connectivity is enabled. As with any publicly accessible host this then becomes the target of ssh scans.

I included the message just to show that between it and the reboot nothing had been logged.

AFAICT there has not been a breach, and I have not seen any indications at all that there may be one.

Re: FreeBSD PVHVM call for testing

[Roger Pau Monné]

Hello,

I've pushed a new branch, pvhvm_v14 that contains support for live
migration. While there I've also rebased the changes on top of current
HEAD, so now it contains the recent fixes to blkfront and netfront.

http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=shortlog;h=refs/heads/pvhvm_v14

Some notes on this branch, I've mainly tested it with Xen 4.3 (unstable)
because previous Xen versions have problems with the PV clock used in
PVHVM when migrating. In order to be able to migrate a PVHVM guest you
will need to add tsc_mode="native_paravirt" to your config file or apply
the following patch to Xen:

http://marc.info/?l=xen-devel&m=137036010517331

I would say that migration across the 4.x series will work without
problems (because they all have support for vector callback injection),
but migrating from 4.x to 3.x will certainly not work. On the other
hand, migrating a guest started on 3.4 to 4.0 should work, although I
have not tested it.

Also, if the migration process fails for some reason, resuming the
original guest on the sender side will leave the VM without working nics
and disks, this is a problem with netfront and blkfront not being able
to resume after suspension if the guest was not actually migrated.

Roger.

looking at your master branch your 2 weeks behind current... so where did
you rebase your changes to head, or are you referring to your HEAD, and not
FreeBSD

No, my HEAD commit from FreeBSD master repository is from 3 days ago:

http://xenbits.xen.org/gitweb/?p=people/royger/freebsd.git;a=commit;h=5311e12c931df9b67b64913670eab76a994317b9

This is the commit where I rebased my pvhvm_v14 branch.

Hello,

There where some issues with the previous branch (pvhvm_v14), I've
pushed a new one (pvhvm_v16) that fixes the following bugs:

 * Make sure there are no IPIs in flight while the VM is migrated,
having in-flight IPIs is a problem because on resume the event channels
are re-initialized, so all pending events are lost, including IPIs.

 * Reset the clock after migration, this prevent clock drifts when the
VM is migrated.

 * blkfront was not correctly freeing the old event channel port.

The following two commits are needed for Xen:

f8e8fd56bd7d5675e8331b4ec74bae76c9dbf24e x86/HVM: fix initialization of
wallclock time for PVHVM on migration

32c864a35ece2c24a336d183869a546798a4b241 x86/vtsc: update vcpu_time in
hvm_set_guest_time

With this branch I've been able to successfully local migrate a busy VM
400 times consecutively.

As usual, the branch can be found here:

Re: FreeBSD PVHVM call for testing

Hi,

I've just built a new kernel based on pvhvm_v17, but it panicked on boot.

I still have a xen console attached, so I can provide additional information if someone gives me the right commands.

Jeroen.

Could you provide the boot log of the DomU, backtrace, Xen version and
Dom0 kernel version?

I did not have a console attached when it rebooted, so I did not have a log of the initial boot. Now that I did, I see that it fails to mount its root volume.

It had been running previously on pvhvm_v10 for about two weeks without problems. I updated my local git, and recompiled the kernel and rebooted. Then this happened.

That's because Justin recently pushed a commit that changed the ad
translation to ada, you should change your /etc/fstab to ada0p2. It's
commit 526f3ad11acb296481215d7c2915b3f30f1844f6.

Okay, everything works again now.

Additionally, I've applied the patches from FreeBSD-SA-13:06.mmap, rebuilt the kernel and rebooted, and the system now works fine.

I did note however that rebuilding the kernel takes an awful lot more time than on a FreeBSD9 system. As in it took about 2 hours longer.

Should we encourage folks to just configure their VMs to use xbd?  I hope some day that the system will just report "da" devices, so the ada name may change again.  We could also suggest specifying SCSI disks in the VM config since I don't think "da" will ever change.

I've never seen a kernel build take 2 hours, much less 2 hours *longer*.  Are you talking about buildworld?  It would be interesting to know your results building stable/9 sources in your 10 environment to see if this is just due to "build bloat" or a true performance regression.

I guess the kernel-toolchain takes a long time to build…and from what I can see it does a clean before rebuilding also.

I'm doing the kernel-toolchain step only now and will report how long it took.

Oh.  Without any parallelism (-j X), the build will take a really long time.  Even with only one core, you'll get a large speedup by performing a parallel build since many steps of the build are I/O bound.

This seems to be it, that took roughly 2 hours to build. The actual kernel is probably pretty fast in building.

> Oh.  Without any parallelism (-j X), the build will take a really long time.  Even with only one core, you'll get a large speedup by performing a parallel build since many steps of the build are I/O bound.

Neither of the systems actually had parallelism defined, either as flag or in /etc/make.conf

Hi,

I have this running for a day or so now, but I'm noticing that the load averages seem a bit off:

$ uptime
11:17AM  up 17:14, 1 user, load averages: 0.31, 0.27, 0.21

This is for a clean install, with just enough installed to compile this kernel. In top I'm seeing that the machine is idling >98% of the time. But this does not correlate to the load displayed above.

This is probably due to the fact that we are not properly accounting for
blocked/runnable/offline time. Did you see the same when running the
XENHVM kernel without my patches?

I have a different system on the same platform running FreeBSD9 with XENHVM. This server is running (web)mail, smokeping and irssi.

That gives:

 11:35AM  up 20:07, 1 user, load averages: 0.06, 0.06, 0.07

Re: FreeBSD PVHVM call for testing

[Jeroen van der Ham]

Hi,

After some more testing I thought it would be good to put this into production for my personal server. I've used pvhvm_v19 and built it without debugging options and installed it on a FreeBSD 9.1 system.

I've run into some hiccups with 9.1 user land and a 10-CURRENT kernel, but that's all solvable[0].

My VPS has some very limited memory (256M), but I've compensated with swap space (1G)

Now anytime I'm putting the system under stress, by building ports or by running a git clone on the kernel repository here, I'm seeing a lot of messages about swap_pager:

> swap_pager: indefinite wait buffer: bufobj: 0, blkno: 132545, size: 4096

The system also becomes very sluggish and sometimes unresponsive.
The weird thing was that one of these messages happened right after a reboot when I rebuilt an outdated port and on the main console was checking the swap memory:

> jeroen:~/ $ swapinfo                                                  [8:13:29]

Is anyone else seeing something similar?
I certainly did not experience something like this on 9.0 with a XENHVM kernel.

If necessary I can rebuild a kernel with debugging support and do some more recording of what is actually going on.

Jeroen.

Is your guest running a 32bit or a 64bit kernel?

Could you also provide the config file used to launch your guest and the
Xen and Dom0 kernel versions?

Could you also try a HEAD XENHVM kernel (without my patches), to see if
the issue is related to my changes or to some bug already present in HEAD?

Will do.

Are you setting the shadow memory size manually because your hardware
lacks HAP support?

This doesn't seem like a standard xl config option.

I've set up a XENHVM system with 256MB of RAM and swap and this is what
I see when doing a make buildkernel:

[root@ ~]# swapinfo
Device          1K-blocks     Used    Avail Capacity
/dev/ada0p3       1048540   351116   697424    33%

I don't see any messages on the console or anything else, the system
seems to be sluggish while doing the build, but that's quite normal when
using only 256MB of RAM.

This test was done using the pvhvm_20 branch, but it should not contain
any significant code changes in comparison with pvhvm_v19 (it's just a
rebase on top of HEAD and a reorder of patches). Could this be because
you are using a 9 userland with a 10 kernel?

Hi,

It seems I was worrying too soon.

I have been putting the system through the wringer some more, and I now believe that it has been caused by adding a new swap file. Just before I rebooted my system I created a larger swap file to be used by /etc/rc.d/add_swap.
Right after I rebooted I started compiling and doing other things. And I am getting the feeling that the system was still initialising that swap file and was unable to provide swap space at that time.

I've rebooted my system again with the PVHVM system, abused it even more than I did before and I'm not seeing the same messages again, nor getting any exaggerated sluggishness.

So my apologies for the false alarm.

Jeroen.

any idea if/when this code will be merged into -CURRENT?

It's already in HEAD, and will hopefully be part of the 10 release.
