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
Well, this means that 'ovsbr0' doesn't exist. Is that so? Can you share your <interface/> configuration and the network XML?
Michal
so if your libvirt's net is like this:
<network> <name>ovs-br0</name> <uuid>e5129e76-1576-4866-97e1-42f14263cfc2</uuid> <forward mode='bridge'/> <bridge name='ovsbr0'/> <virtualport type='openvswitch'/> ....
then you need extra(extra for ovs tools create both for us at bridge creation time and nmcli(you) need to create those explicitly) port+iface so this:
$ ovs-vsctl show
output will contain this:
...
Port "ovsbr0" Interface "ovsbr0" type: internal
That is expected. <forward mode='bridge'/> is document like so: https://libvirt.org/formatnetwork.html#elementsConnect Michal
