I noticed your xml (I've reformatted it) says:
<source type='unix'
path='/usr/local/var/run/openvswitch/vhost-user-1'
modde='client'/>
One property I see is modde, is that a typo from transferring to your
mail client?
Here's a working example I have (for reference):
<interface type='vhostuser'>
<mac address='52:54:00:e7:b6:8d'/>
<source type='unix' path='/var/run/openvswitch/vhost-user-1' mode='client'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</interface>
I don't think that the <address ../> tag is needed.
