Hi everyone, I'm forwarding this mail that I wrote to OpenVSwitch

What did you think about the patch to libvirt that I'm using?. At
least, it worked for me :-)
I'm not familiar with openVSwitch enough myself to give definitive
answers, but I will point out a similar thread with a similar concern...
Thanks.

Subject: OpenVSwitch and libvirt integration problem at shutdown/reboot
To: dev(a)openvswitch.org
Hi everyone, this mail is related to a bug report that I did on Debian
(#701760) that I wasn't able to resolve yet and want to know if
someone has the same problem and how could I fix it.
The problem that I'm having is that on shutdown/reboot of the machine
that holds the virtual machines that use OVS, the OVS-Switch is going
down before libvirt finish to shutdown the VMs.
If we know that libvirt is relying on some other service being present,
then it is in our best interest to guarantee shutdown ordering between
the two services so that libvirt always shuts down before OVS-Switch. I
have no idea what the service name for this would be, but check out this
patch for the approach to get systemd to enforce a shutdown dependency:
