[SL] Jayakeerthi, does an OVS bridge named "1511" exist? If not, then you'll
see an error.
Did you edit the libvirt domain XML to be sure to tell libvirt that you're
using OVS? If not, then you'll see an error.
It's entirely possible (I don't use virt-manager, so I don't know for
certain) that this is a virt-manager issue. Have you tried using virsh
instead of virt-manager?
