Mask X86_FEATURE_XSAVE in cpuid leaf 1, ecx, as we don't allow guests to
use it (by setting cr4.OSXSAVE).
This prevents crashes in pvops dom0 kernels, as new versions of Linux try
to use this feature.
(This patch deals with dom0 cpuid; I'm not sure where the right place to
set up the default mask for domU is.)

Mask X86_FEATURE_XSAVE in cpuid leaf 1, ecx, as we don't allow guests to
use it (by setting cr4.OSXSAVE).
This prevents crashes in pvops dom0 kernels, as new versions of Linux try
to use this feature.
(This patch deals with dom0 cpuid; I'm not sure where the right place to
set up the default mask for domU is.)

I actually disagree to this. The kernel should be dealing with the situation
by inspecting the OSXSAVE bit in CPUID when running under Xen, since it's
really Xen that's the 'OS' for that particular feature.
Then, once Keir gets willing to take Intel xsave patch(es), no further change
is going to be needed here. And the same kernel will work (assuming it has
no other dependencies) on older Xen not having this bit masked.

If you¹re using a recent xen-unstable then you might try again with the
current tip. A couple of changes went in recently (including one fix today).

It seems reasonable to mask XSAVE for now though. I don't think it can
usefully be used without some Xen support.

I'm not sure whitelisting will be much better than blacklisting - while now
any feature requiring not-yet-implemented support in Xen must be turned
off explicitly, this would just turn over to requiring explicitly un-hiding any
new feature not requiring Xen's intervention. A real solution to this issue
would require some assistance from the hardware vendors I'd think.

Well, it makes the difference between working but without the new feature,
versus quite possibly simply not working at all (and failing in rare and
subtle ways, perhaps). Isn't one obviously better than the other?

Just cloned,built and installed the most recent xen-unstable.
Seems like "make tools" reports some errors , but still finishes with no
error message.

The next attempt after DomU shutdown brings it to paused state.

If you¹re using a recent xen-unstable then you might try again with the
current tip. A couple of changes went in recently (including one fix today).

You mean Xen support to deal with a new CPU context structure, or
something requiring specific guest code, like what's needed to support
sysenter/syscall?

I mean it indicates new CPU context requiring context switching. But, fully
generally, who knows? :-)

Seems like new kernel brought up back some old issues with ubuntu 8.10
devices. It never happened before patching 2.6.29-rc7 kernel on C2D boxes with the same ubuntu 8.10 server release and 2.6.29-rc5.
In particular, CentOS 5.2 PV DomU's xen-hotplug.log looks like:-
xenstore-read: couldn't read path /local/domain/2/vm
xenstore-read: couldn't read path /local/domain/9/vm
xenstore-read: couldn't read path /local/domain/3/vm
xenstore-read: couldn't read path /local/domain/4/vm
Either xen-tools (or whatever else in xen unstable) requires correlation
with patched kernel.

Just cloned,built and installed the most recent xen-unstable.
Seems like "make tools" reports some errors , but still finishes with no
error message.
CentOS 5.2 PV DomU may be loaded OK only the very first time.
The next attempt after DomU shutdown brings it to paused state.
After "xm unpause DomainName":-

current tip. A couple of changes went in recently (including one fix today).

Ah, I noticed that too, but I don't see any obvious changes which might
have caused this. Time to pull out "git bisect" I think.

disk= [ phy:/dev/sdb5] seems not to be released after PV DomU shutdown.
Hence , second attempt to load DomU gets paused waiting for particular
device. When i reboot xen host, DomU can be loaded again.

I've got the same issue with CentOS 5.2 PV DomU (same /dev/sdb5)
under Suse's 2.6.27 xen-ified kernel & Xen Unstable ( the most recent).
I believe Xen is broken in some way. It's not about the kernel.

It never happened before patching 2.6.29-rc7 kernel on C2D boxes
with the same ubuntu 8.10 server release and 2.6.29-rc5.

second boot up

I believe it's not about kernel, it's about Xen Unstable.
It's broken in some way.

Blktap helps out for multiple CentOS PV DomU restarts (with image on FS) under Suse's 2.6.27 xen-ified kernel & Xen Unstable ( the most recent).
But it seems not implemented yet for 2.6.29-rc7

disk= [ phy:/dev/sdb5] seems not to be released after PV DomU shutdown.
Hence , second attempt to load DomU gets paused waiting for particular

It never happened before patching 2.6.29-rc7 kernel on C2D boxes
with the same ubuntu 8.10 server release and 2.6.29-rc5.

Ah, I noticed that too, but I don't see any obvious changes which might
have caused this. Time to pull out "git bisect" I think.

second boot up
under Novell's 2.6.27 & Xen Unstable ( the most recent).
I believe it's not about kernel, it's about Xen Unstable.
It's broken in some way.

So your conclusion is that there's a regression in the tools stack when

It's not so important for me. The important thing is:-
CentOS 5.2 PV DomU may be loaded only the very first time under Suse's 2.6.27 xen-ified kernel & Xen Unstable ( the most recent). Attempt to shutdown and start it again gives VBD cannot be connected . Hotplug scripts not working. That's a core issue, same behavior as under 2.6.29-rc7 (with XSAVE patch ). Kernel doesn't seem to be a root cause.
I believe Xen unstable is broken in some way.
Boris.

Could you try bisecting xen-unstable to see which change started failing
for you? There were some recent changes to the hotplug scripts which
could have introduced a problem.
However, I'm pretty sure I started seeing this problem without updating
my usermode tools, so there could also be a kernel problem. But its not
obvious what it might be.

If you're fetching xen-unstable with "hg" and building it, then you have
everything you need to do bisection:
1. hg bisect -r
2. hg bisect -g <known good version>
3. hg bisect -b <known bad version>
4. build as usual and test
1. if works: hg bisect -g
2. if not: hg bisect -b
5. repeat 4 until first bad version has been isolated

I didn't get a chance to notice the last good version , because pygrub stopped working (return no data ) right after XSAVE patch (for myself, of course) .

This sounds very much like the problem I described in thread subject
"domain id number on xen unstable", I maintain my own 2.6.27 dom0
kernel using opensuse Xen patches which I rebase to apply to vanilla
without the many other patches opensuse usually applies to the kernel
tree, so from a Xen point of view I am using a very similar kernel to
yours, I found that I could start a hvm but after shutting it down
attempting to restart it would fail or hang, sometimes I got hotplug
error that vbd could not be connected.
The script that has problems on my system is xen-hotplug-cleanup , the
first time it is run it puts a lock in /var/run/xen-hotplug and never
removes it, so the next time the script runs it blocks waiting for the
lock and eventually times out.
The offending line in the script is:
vm=$(xenstore-read "/local/domain/${path_array[2]}/vm")
putting a echo immediately after that line shows that nothing after it
is executed, which is why the lock is not released.
replacing xen-hotplug-cleanup and xen-hotplug-common with the ones
from 3.3.1 seems to help, but after starting and stopping a few vm's
the entire system reboots, so I think some objects are not being
cleaned up, not surprising really, can hardly expect scripts to work
with the wrong version of Xen.
This problem has got me stuck into a nasty corner, only Xen unstable
can fit our virtualization requirements (need viridian for stable
windows smp), but the Xensource kernel is too old for our hardware.
I am going to put some serious effort into debugging this in the next few days.

Change 19242:226031d62fc5 is the last one which works for me. I haven't
managed to bisect which specific change the problem starts occuring in,
but 19250:b3774712e654 seems like a good starting point.

Hm, perhaps not; it doesn't work for me now after a reboot. I realize
now that I wasn't restarting xenstored between tests.

I have just managed to get the Xensource 2.6.18.8 kernel working on
one of my test systems and this problem still happens, I updated Xen
unstable to latest hg as well, so this is definitely not a kernel

any more, and xenstore-ls shows that objects are not being cleaned up

Yesterday 2.6.29-rc7 ( built on 03/08/09) kernel worked fine under Xen Unstable (rel 19317).
Today a new fresh kernel 2.6.29-rc7 has been built. The most recent rc7
kernel under Xen Unstable (rel 19317) generates an error (vif) cannot be connected, hotplug scripts not working when i attempted to start f10 PV DomU
or SNV_106 PV DomU.
Status of Xen seems to be OK due to same DomUs functionality under
Suse's 2.6.27-5 & Xen Unstable (rel 19317), it is absolutely normal.

Yes, I think there's a second problem in dom0, which has similar
symptoms as the other hotplug scripts bug. The scripts bug confused
efforts in tracking down the dom0 problem. I'll have another go at the
kernel side today.

A heads-up that I just got a "(tap)...Hotplug scripts not working"
completely unrelated to pvops.
I updated hypervisor and tools (but notably NOT dom0 kernel) to
xen-unstable c/s 19355. Launching a domain now fails with the
above error. Rolling tools (only) back to 19187 makes the
problem go away.
Is there maybe a new dependency between tools and dom0 kernel?

There's certainly nothing explicit. Bisecting the kernel seemed to
point to some cleanups I did around /dev/privcmd, but that's not really
used for hotplug/xenbus stuff (I mean, it is at a low level, but surely
xenbus would break entirely if it were broken). And those changes work
with older tools. (And the bisection was probably lead astray by the
other hotplug bug.)
Maybe some timing/ordering thing? Unfortunately I know very little
about how things are supposed to work at that level. IanC said that he
thought that xenbus watches were failing to fire, which makes me wonder
if Gerd's xenstore fixes might be worth looking at more closely.

You could try reverting changeset 19342, as most likely culprit.

Is that the fixed xen-hotplug-cleanup change? The symptoms aren't quite
the same; with the broken cleanup, there were lockfiles left lying
about, so all the "block add" scripts were blocked waiting for the lock
to be released. In this case, everything is just sitting there; the
hotplug never seems to get started.

The most recent 2.6.29-rc7 under Xen (release19317) shows up
hotplug issue at the very first start up.
When i revers back to rc7 built on 03/08/09 under same Xen, hotplug issue
gets gone.
I gonna test Xen(19355) with Suse 2.6.27-5 kernel
Boris.

I think the hotplug problem where the lockfile was left lying about is
fixed, I updated to c/s 19354 today and since then no problems with
hotplug scripts, I can start and stop domains cleanly or by destroying
them and nothing is left behind, I've verified this by running the
xen-hotplug-cleanup script manually and it completes and removes the
lock as it should.
Like boris I am using a opensuse kernel, so if he is still having
problems I think he has another issue or there is a remaining problem
with hotplug which for some reason doesnt trigger on my test system.
There is a separate issue where Xen crashes with (XEN) **
page_alloc.c:534 -- 0/1 ffffffffffffffff which started around the same
time the hotplug scripts were fixed, it happens regardless of which
kernel is used and has been discussed in thead with subject "xen
unstable crash".

Suse's 2.6.27 xen-ified kernel & Xen Unstable (19355) don't have any problems
with hotplug sripts. I've restarted F10 PV DomU several times.

Well I've been struggling with this on and off since Friday and
am having major problems because there are now many parts that
I'm no longer sure how to synchronize. The tools now seem to
be dependent on ioemu but I don't know how (or if its possible)
to synchronize versions of the ioemu git tree with a specific
xen hg changeset. Rolling xen tools back to 19187 worked fine,
but I couldn't roll the tools back to tip due to a compile error
ioemu-dir/hw/pt-msi.c:95: error: too few arguments to xc_domain_update_msi_irq
I did a git pull in ioemu-dir and no longer got the compile error
but it didn't help (same hotplug problem) and now I can't rollback
xen tools to 19187 because I get the opposite compile error.
So my test machine, which HAD been working at least with tools 19187
is now useless unless I solve the problem.
(BTW, I tried reverting 19342 and it didn't solve the problem.)
I was able to do a fresh tip build and install on a new test machine
(that previously had no xen on it at all), so I suspect my problem was
due to a mismatch between dom0 and "something else" so am now in the
process of rebuilding dom0 from latest.
Argh! I thought bisecting was supposed to be easy!
With so many interdependent parts (and two different change-tracking
tools needed), perhaps its time to start being more careful about
describing version interdependencies between them?
Or maybe if I were sufficiently knowledgeable about both mercurial
and git, this wouldn't be a problem?

Yeah, having xen-unstable in two different source systems is extremely
brittle; I don't think its sustainable for much longer.

No, its all a big pain, especially since there are multiple bugs with
similar symptoms.
There was the original hotplug script bug in xen-unstable, which now
appears to be fixed.
There was also a pvops dom0 bug, which turned out to be an upstream bug
in vsprintf()'s handling of "%.*s", which is also now fixed.
And there may well be some other bugs...
