At the time of creation, its throwing the following error: Does virt-manager support creating XML files with the OVS backend yet? It didn't years back when we added the support into libvirt. Yes. I used virt-manager in ubuntu 12.04 to create VMs with openvswitch-1.7.1 in bridge mode. xml files were created for each VM, and I modified those xml files to add multiple interfaces. I am not sure what is the problem with current virt-manager. Anyhow, will figure it what is happening. Thanks, Ramana. unable to complete install: 'Unable to add bridge br0 port vnet0: Operation not supported' I am not good at libvirtd library and how its working with kvm, but I could not see any error when I created br0 using brctl command after loading linux bridge module( with out openvswitch module). But I did the same setup with ovs-1.7.1 with libvirtd 0.9.8 version, and its working fine. At this time, I am not sure whether its the problem with libvirtd or some thing else. Thanks, Ramana.
