[PATCH V3 0/5] Reintroduce OVMF support

[PATCH V3 0/5] Reintroduce OVMF support

[Wei Liu]

OVMF (open virtual machine firmware) is used to provide UEFI support for
virtual machines. It was first introduced about a year ago but was disabled due
to compilation problem. Now that the compilation problem is resolved we can
reintorduce it.

OVMF tree can be pulled from
  git://xenbits.xen.org/people/liuw/ovmf.git for-xenbits

Wei.

Change from V2:
* update Config.mk before enabling OVMF build

Ian Campbell (3):
  tools: clone ovmf to ovmf-dir directory
  tools: support system supplied ovmf binary
  tools: Enable OVMF build by default

Wei Liu (2):
  libxl: bump LIBXL_MAXMEM_CONSTANT to 2048

[PATCH V3 1/5] libxl: bump LIBXL_MAXMEM_CONSTANT to 2048

[Wei Liu]

When using OVMF we need to have 1MiB of memory in place for firmware.
Without this change we have:

(XEN) HVM128: Loading OVMF ...
(XEN) page_alloc.c:1460:d128 Over-allocation for domain 128: 33025 > 33024
(XEN) memory.c:132:d128 Could not allocate order=0 extent: id=128 memflags=0 (0 of 1)

This is not a fatal error as hvmloader will instead use low memory to
load OVMF, but it's better to eliminate such error.

Changing this constant doesn't necessary increase the total amount of
memory a guest uses because it's just a limit.

[PATCH V3 4/5] tools: support system supplied ovmf binary

[Wei Liu]

From: Ian Campbell <ian.campbell@citrix.com>

Debian Jessie at least contains an ovmf package that includes
/usr/share/ovmf/OVMF.fd. It's also possible that user may want to supply
his/her own ovmf binary.

This patch update only the ovmf changeset but not the repository, now 
git://xenbits.xen.org/ovmf.git is not updated, so you have to update it 
or change also repository to git://xenbits.xen.org/people/liuw/ovmf.git.
All other things look good to me, now I test this series of patches.

I don't have the permission to push to that repository so I need to
defer this to maintainers.

Again, you can probably wait until this series go through push gate
before conducting any test.

For this patches serie:
Tested-by: Fabio Fantoni <fabio.fantoni@m2r.biz>

About ovmf:
I don't have uefi domUs ready, so I did a fast test with windows 7 pro 
64 bit dvd and starts, spice it works.
The problem found for now is very bad general performance and at the end 
of windows installer loading the domU reboots.

Oh Windows... :-P

It would be useful to have at least some hypervisor / QEMU logs.

I know that quality, efficiency, stability and security do not exist in 
the Microsoft vocabulary...
Unfortunately almost all users for desktop/workstation use windows (for 
now) and even at the time I still use it for work due to some programs 
that only run on windows (and often are made very badly) :(

I found this error on xl dmesg:
> (XEN) mm.c:620:d0 Could not get page ref for pfn ffffffffffffffff
I see a recently posted patch about pfn:
http://lists.xen.org/archives/html/xen-devel/2013-10/msg02028.html
Can this serie solve the problem and I have to try it or has nothing to 
do with this?

And this is the error that cause reboot of domU:
> (XEN) hvm.c:1274:d4 Triple fault on VCPU0 - invoking HVM shutdown 
> action 1.

I not found any other error or relevant information on logs but I attach 
them if you want see.

I also tried with Ubuntu 12.04.3, same pfn error on xl dmesg, same 
performance problem (some minutes only for arrive to grub-efi of dvd) 
and after other 10-15 minutes without complete the boot I did a destroy.
Also for that logs on attachments.

Despite windows is bad, it seems that problems persist even in the test 
linux except the shutdown with vcpu issue.

The dom0 used have the installation of this:
http://lists.xen.org/archives/html/xen-devel/2013-10/msg01111.html
Except the git branch used (here the hvm-improve.t6) and the qemu:
QEMU_UPSTREAM_URL ?= 
git://xenbits.xen.org/staging/qemu-upstream-unstable.git
QEMU_UPSTREAM_REVISION ?= master

If you need more informations and/or tests tell me and I'll do/post them.

About legacy bios support that I mentioned days ago I found this 
document about:
http://code.coreboot.org/p/seabios/source/tree/master/README.CSM
Seem that need ovmf change (and probably also on hvmloader) that are not 
able to do.

Thank for any reply and sorry for my bad english.

Don't get me wrong. I'm just saying debugging Windows with no source
code available is beyond my ability. :-)

I don't think that patch is useful to fix this at first glance.

AFAICT this is a limitation of Xen's physmap implementation.  I'm still
investigating a proper fix for this -- unfortunately that might
involving modifying Xen's most complicated part so don't hold your
breath.

Windows, right? Could you try Linux?

Is QMEU busy-looping?

Oh please don't use staging QEMU. That introduces a new variable which
makes it very hard to identify the genuine problem.

Re: [PATCH V3 2/5] Config.mk: update OVMF changeset

[Wei Liu]

Just notice you also attached log files...

You can just inline them in mail or attach them one by one instead of
making zip / tarball -- this will be much easier for people to look at
them.

I probably not understand exactly what you mean, the domU seems continue 
to boot apparently but in very slow motion.
Qemu is always active and with low load (on average 5% cpu).

Is based on latest qemu stable (1.6.1).
I tested 1.6 fora long time without see regression and seems more good 
than 1.3 on something.
Are there specific reasons to use an older version instead?
If there were it would not be a problem for me to recompile/re-test with 
a qemu previous.

OK. I get it. 5% CPU is OK and expected at this stage.

To get an idea what your guest is doing you probably need to setup
serial console.

If it is working fine for you then it is OK.

But IMHO it is generally better to wait for specific changeset to go
through push gate before conducting your test because that reduces the
variables which might cause regressions.

I also tried another build without change qemu repo and changet but same 
result.
Do you have domUs working on ovmf? If yes what are differences from my 
test system?

I tried to change also domU parameters:
- removing audio, vdagent and usb redirection it changes nothing.
- switch from stdvga to cirrus vga solves the performance problem, but 
with Precise it shows always a black screen after start of grub-efi 
entry, and black screen also with windows 7 installer.

What domU vga you used on your tests?

I'm trying to setup ovmf serial console, but I have no idea on where to 
start from. Do you have some suggestions?

Thanks for any reply.

Cirrus, because there's cirrus driver in OVMF. I don't know whether
there is driver for stdvga.

Black screen is expected because there's probably something wrong with
OVMF / Xen. I need to check real hardware behavior to identify the
problem.

Add serial='pty' in you HVM guest config file. I believe you can get a
tutorial on wiki.xen.org

Thanks and sorry for the stupid question.
Precise's boot stops with calltrace, log on attachment.
I'll try also with latest ubuntu version (Saucy) with newer kernel 
(3.11) and with latest stable qemu version (1.6.1).

This idea could be enable legacy bios and vgabioses support on ovmf... 
Is that really stupid question to not deserve an aswer?
Thanks for any reply.

I tried with saucy and it boot but has graphic performance issue and no 
mouse.
About windows problem it is probably due to a missed cirrus driver on 
windows 7.
The only other option that I found should be try with stdvga but seem it 
needs legacy vgabios from csm.
What if I try to add ovmf patches for legacybios (that seems to have 
also memory patch) from this git?
http://git.infradead.org/users/dwmw2/edk2.git
Does it make sense without modification to hvmloader?
Thanks for any reply.

It's really hard to tell whether these out-of-tree patches will be of
any help for the cuurent situation.

Sorry, I try to better explain what i meant:
In my earlier mail, what I was asking is:
since the patch to OVMF to prevent it from marking the region from 
0xC0000-0xFFFFF as read-only before invoking Legacy16Boot method is 
already present on the git I've linked, I was asking if such a patch 
should works without any further modification xen-side.
On the other hand, if you think the patch will never work without xen 
modifications, I'll not test csm now but I'll wait xen change.

It will allow a guest to try and use up to 1MB more though, and it
allows this for PV guests as well as HVM guests not using OVMF.

There's only a small number of place which use this constant, can we
refactor them into a helper function, which can then be expanded to
include a per-BIOS overhead in addition to this one? The BIOS selection
is stored in xenstore, so that work even for calls which don't have the
domain configuration to hand.

(does anyone remember what the existing 1MB is actually for?)

Happened to come across this when I was looking at other problem.

It looks like that constant was never intended to use in the way it is
now. Hah.

Indeed not.

I vaguely recall that the xapi folks add a bit of slack to the domain
size while they are doing the calculation to see if it fit will on the
host, but not actually when they build the domain. (note that this
therefore only matters for the domain being built, and not cumulatively
for all domains, which makes a difference to the overall overheads on
the system). We could try switching to a model like that and see what
breaks I guess?

I've CC'd a couple of xapi folks so they can correct my no doubt faulty
memory ;-)

Andy Cooper told me on IRC
        Xapi adds the slack when building the domain.

Apparently not doing so cause unspecified fallout. Which isn't to say
that's xapi specific and xl would be fine.

Yeah.. theoretically I think that we shouldn't have that constat at all.
In practice it could cause stability issues, maybe difficult to narrow
down. Maybe we should remember to remove it at the beginning of the next
development cycle and see what breaks? Keeping in mind that OSSTests is
really unlikely to find any of these issues, we should probably try to
get the community more involved with the testing.

The reasons for keeping it are based mostly on folklore rather than an
actual understanding of the issues, which may not even be real, and it's
wasting (cumulatively) a fair bit of RAM.

But waiting until early in the 4.5 cycle is probably a good idea.

I've created a bug (with this mail) to remind us to do this.

I have pushed these.

Wei told me that more work was needed to make OVMF usable, so on his
recommendation I have held off on this one.

This one was previously ruled out.

I have applied this one.

Thanks Wei.
