Hello.
We notice a very upsetting behavior of how libvirtd deals with running domains after being restarted.
Namely, in 10-20s after start libvirtd may accidentally kill a random number of running (qemu) domains with SIGTERM.
Here is what we get in libvirt log:

And this is what we get by grepping 45766 in separate logs of vms:
drafter@10-5-0-11:/var/log/libvirt/qemu$ sudo grep -A 1 45766 *
vm010-001-206-002.log:qemu: terminating on signal 15 from pid 45766

vm010-002-011-002.log-2013-02-27 12:35:21.772+0000: shutting down
Specifically here libvirt killed 4 vms just after start.
Before that occasion we just shut libvirtd off and started again (stop/start).
Will be very grateful for any ideas on this matter.
