[libvirt-users] Cannot get interface MTU - qemu quest fails to start off OpenVswitch

hi guys

I have a qemu guest and openvswitch bridge and the guest fails to start:

$ virsh start work8
error: Failed to start domain work8-vm-win2016
error: Cannot get interface MTU on 'ovsbr0': No such device

LXC guest which uses the same source network starts just fine.

I'm on Centos 7 with openvswitch-2.9.0-3.el7.x86_64 from
centos-openstack-pike repo and libvirt-4.5.0-10.el7_6.7.x86_64.

Would anybody care to suggest a possible reson(s) causing the failure?

many thanks, L.
