Hmm, I don't seem to be seeing this now...

Comment 2 Tim Waugh 2009-08-28 09:01:47 UTC
...and of course it just happened again, while shutting down an F-11 guest.

Comment 3 Mark McLoughlin 2009-09-04 13:06:09 UTC
I can't reproduce this

Was it a segfault? Can you get a stack trace?

Comment 4 Daniel Berrangé 2009-09-10 09:00:44 UTC
Can you provide the guest configuration file which exhibits this crash.

Also is this being seen with a guest whose disks are on NFS as per your other bugs ?

Comment 5 Tim Waugh 2009-09-17 10:53:57 UTC
It turns out libvirtd is still running but virt-manager's connection to it is broken.

No, the disks are not on NFS.

$ ls -Z /home/twaugh/VM/RHEL54.img

I was hitting this issue as well, but not anymore after updating libvirt to latest rawhide version (libvirt-0.7.1-1.fc12.x86_64). Tim, can you give that a shot?

Guest was win2003, no fancy setup, just a single ide disk. shutdown (not destroy) caused the issue. virsh list would show 'nostate' for the VM, and all 'info' calls would fail with "could not query memory balloon'.

There is another bug filed to handle virt-manager's poor behavior in coping with this situation (bz 522168).

Comment 8 Mark McLoughlin 2009-09-21 14:42:37 UTC
twaugh: has latest libvirt fixed it for you too?

Comment 9 Tim Waugh 2009-09-21 15:39:34 UTC
I'm not seeing it break with libvirt-0.7.1-4.fc12.x86_64.

Thanks Tim
