Thanks for double checking. I do wonder why I didn't see this during my test though. A temporary work around is to set group = kvm in /etc/libvirt/qemu.conf . It turned out as expected. The necessary initgroups logic was added post post 0.8.6 while squeeze has 0.8.3. (I also spotted the reason why my testing on squeeze incorrectly succeeded to open /dev/kvm which was just related to the local setup). I'll have a look into backporting the relevant parts. This of course results in files being owned by the kvm group (which is what we wanted to avoid in the first place). The alternative workaround is to change the group of /dev/kvm to allow access for the libvirt-qemu group. Cheers, -- Guido Cheers, -- Guido Cc'ing also the security team.

It looks like libvirt-qemu user should have permissions on kvm then. Older libvirt (prior to 0.8.6) lack the proper initgroup calls. Without these the process runs as libvirt-qemu:libvirt-qemu without any othter group membership and therefore isn't allowed to access /dev/kvm. That was the main motivation for using group kvm instead of separate group in squeeze. I vaguely remembered this when preparing the sec update and therefore did extra testing but since the only kvm capable squeeze box around here had a non standard setup (I need to test the stable as well as the backports version on that one) this problem didn't show up and I didn't check the code itself.

Hi,
attached is a debdiff that fixes the issue. I'd be great if somebody
could check out the packages at:
http://honk.sigxcpu.org/projects/libvirt/snapshots/
I didn't squash the upstream commits so we can easily pull in more stuff
iff needed.
Cheers,

I have tested the package in the environment where I confirmed the problem this morning. With 0.8.3-5+squeeze5 the problems went away. Further testing done was: with existing vm, create new snapshot, revert, delete old snapshot. Worked all as expected in these cases. Thanks for the quick followup!
