What exactly did you change in <interface> XML section to get it to work
again (e.g. did you add the <target> element)? What about the "ovs-vsctl
show"
output, when the VM did not start? If you added the <target> element, then
it
seems to be more like a workaround, not a correct solution.

It could be that virt-install does not allow to specify <target> element.
Anyway, your best chances are to ask this on libvirt mailinglist or use
"virsh edit" command after the VM is already created.
