Hi. My kvm domains didnt' migrate too until I noticed I was missing the package
kvm-pxe in the destination server.
Now it works like a charm with Ubuntu server 10.10 64 bits.

I see this issue with 10.10. But I also see it when:
- KVM guest is saved
- KVM guest is restored
Although virsh list shows the guest is running, it is not. I have to
suspend / resume the guest to make it run again.
It happens with ~50% of save/restores.

VM is suspended after live migrate
Well Question then?
Karmic is to be supported for another year, correct?
This is a bug with karmic correct?
the workaround is to suspend and then resume the vm this removes live
migration from the mix if I have to do the suspend and resume. Why not
just backport libvirt-0.7.2 from the version
Mark , I fully agree.
It should be fixed in Karmic.
I'm not going to use Lucid in production for the next 3-4 months.
It has to prove to be stable first.
Is it so hard to fix this bug? Probably it's not high on the list to be
fixed.

Mark, EAB,
Dustin already commented on the status of this bug for Karmic and
believes it does not qualify for an SRU. Please feel free to read
https://wiki.ubuntu.com/StableReleaseUpdates and if you would like to
submit a debdiff and open a task against karmic.

VM is suspended after live
Jamie,
This bug was originally defined on 10-13-2009 the release of
Karmic was on 10-29-2009 This should have been fixed.
It was confirmed on 10-20-2009 and again on 10-29-2009. Then
marked as medium imporantance and confirmed.
I understand that you don't want to fix it
Mark, I understand your frustration, however keep in mind that the final
week before Release will only have the highest impact bug fixes to
reduce the chance of regression in the final release. Bugs are deferred
to '-updates' all the time in the week(s) prior to release for exactly
this reason.
Based on comment #14, this appears to be fixed in Lucid. Please reopen
if you're experiencing this problem there.

Sorry but I disagree,
Lucid is only in beta Karmic needs fixed! Lucid will not be released
for 30 days. But since lucid will be released before a fix for Karmic
is complete I guess all of us will need to wait.

Mark-
Can you reproduce this problem in Lucid?
Lucid is still open for development, whereas Karmic is not.
If you want to ensure that this gets fixed in Ubuntu, it would be best
to test it in Lucid.
Given the nature of the bug, I don't think it meets the SRU
requirements defined in:
*
In Karmic there is a workaround.
In Lucid this problem is not reproducable.
I also think it don't meet the SRU.
6 months ago when I reported this bug I hoped the bug to be fixed within a
couple weeks, but now I rather wait a month and test al needed features again
and again in Lucid (doing it

Here's an interesting addition to this problem:
In my cluster, one system is based on a core2duo CPU, while the other is
based on an i7 920 CPU. When the VM is originally started on the i7,
migration doesn't work. When it's originally started on the core2, it
does. From this, I'm guessing that

Brought HostA up-to-date:

libvirt-bin 0.7.0-1ubuntu13/.1
qemu-kvm 0.11.0-0ubuntu6.3
Ok, updated to the latest libvirt packages from PPA:dnjl/virtualization.
Now, the migrate, then suspend/resume suggestion works for me. Still
less than ideal, as it kills the whole live migration thing, but at
least it doesn't totally kill my VMs anymore.

Is there any status update on this?
Will Lanuchpad be updating the libvirt packages with the patched

I've just tested live migration (as I wrote above) with Karmic hosts and
guest one. Guest still hangs after migration but virsh suspend + virsh
resume on destination host helps guest to continue work. Bug is still
reproducable on Karmic...
# uname -a
Linux kvm 2.6.31-16-generic #53-Ubuntu SMP
Some host and guest updates ago, the suspend/resume worked on my Karmic
64 hosts with a variety of guests, including Window 2008 R2, Windows XP
and various Ubuntu releases. Now, when I try to suspend and resume, upon
resume, the machine reboots instead of resuming.

What guest os you are running?
I've just roll back my host OS's from karmic to jaunty. And found that
migration passed ok with windows xp/2003 guests and fails for ubuntu and
centos guests (guests hangs after migration). I'll try to reproduce it
with the same guests on karmic later...

This was with a hardy/amd64 guest OS. I haven't tried any other guests,
because the bulk of our VMs are supposed to be LTS installs.

I'm seeing behaviour that looks like this on karmic/amd64, only a
suspend/resume doesn't fix the VM. It stays hard locked. I can connect
to it on the virtual serial console or via VNC, and it shows what was
there before the migration, but it never unlocks and starts working.
