Description Matthew Booth 2009-09-09 16:17:14 UTC
Description of problem:
virt-manager had been in use. On coming back to the windows I noticed that virt-manager was displaying:

localhost (QEMU) - Not Connected

I had not disconnected it. Double clicking does not reconnect, and generates the following log entry every time:

Sep  9 17:00:40 mbooth libvirtd: 17:00:40.843: error : qemudDomainGetMemoryBalloon:3369 : operation failed: could not query memory balloon allocation

Looking back in the logs, this looks suspicious:

I can still execute virsh commands, but virt-manager will not reconnect. Restarting libvirtd (without restarting virt-manager) fixes the issue.

This is the second time this has happened in 2 days. I can't think of a common cause.

Version-Release number of selected component (if applicable):
libvirt-0.7.1-0.1.git3ef2e05.fc11.x86_64
virt-manager-0.8.0-1.fc11.noarch

Comment 1 Mark McLoughlin 2009-09-11 14:28:00 UTC
Matt: can you get a ~/.virt-manager/virt-manager.log from when this happened?

Comment 2 Gianluca Cecchi 2009-09-15 10:39:19 UTC
I have the same with f11 x86_64 and virt-peview repo
virt-manager-0.8.0-3.fc11.noarch
libvirt-0.7.1-0.2.gitfac3f4c.fc11.x86_64
qemu-0.10.92-1.fc11.x86_64

If I have virt-manager window open and I shutdown a vm (with button shutdown -> shutdown), as soon as the VM halts, the virt-manager connection drops.
In my case I can double click again the row with "QEMU(localhost)" to have the connection up again....

I can attach a video recorded with gtk-recordmydesktop if you wish in ogv format 
(2.2Mb...)
I'm going to attach my virt-manager.log

Comment 4 Cole Robinson 2009-09-18 16:26:40 UTC
virt-manager's screwy behavior should now be fixed in rawhide. Can any people that were hitting this bug head over to bug 519667 and provide info/confirm the libvirt fix there? Thanks.

Comment 5 Gene Czarcinski 2009-09-18 17:14:57 UTC
Just updated and I can now clean shutdown a guest (previously got "vnc connection lost").

Comment 6 Gianluca Cecchi 2009-10-02 13:41:30 UTC
Ok for me too. Thanks
