I'm using vers 1.84 of QEMU/Kvm from dnjl's PPA for Lucid.

After trying again, I can no longer get snapshots to work whilst vm guest in running.

I have disabled apparmor so that it is only in 'complain' mode on the host, but still get :-

Error -5 while writing VM

whilst trying a

virsh # snapshot-create openerp

Whether running virsh as normal user or root. I'm also getting

'libvirtError: Timed out during operation: cannot acquirestate change lock' errors too, after I've tried to take a snapshot.

Apologies after replying to my own post. After applying the latest update of kvm, libvirt etc from Daniel Baumann (dnjl)'s PPA (the one I had been previously using), I noticed a change was related to giving more permission to libvirt relating to access to disk storage when apparmor is running.

With this update 0.8.1-2ubuntu1.1~dnjl1~lucid0, snapshots are fine again now. I can create/delete whilst guest is running or shutdown
