<br>Can you check and see if the configuration changed as a part of the upgrade?
<br>This should give you something like libvirtd.conf.rpmsave which is the original file.

<br>> After upgrade to libvirt-0.9.11.3-1 I'v got an unstable work of engine. Engine began to lost connection with VM's. VMs worked correctly, but their status in engine were "not responding", migration didn't work also. After downgrade to libvirt-0.9.11-1 engine began to work correctly. Hosts are fedora16 with 3.3.4-1 kernel, qemu-kvm-0.15.1-4. I tested libvirt-0.9.11.3-1 on different builds of vdsm/engine
