2) it looks like this config was generated by OpenStack. Why are you
starting it via virsh? I don't use OpenStack myself, but am assuming
that a lot of the objects referenced in an OpenStack-generated libvirt
domain config are auto-created by some piece of OpenStack code just
prior to starting the domain. For example, the bridge device (there is a
separate bridge device created per guest interface) and the filter that
is applied to that interface (likewise). I was of the impression that
OpenStack instances needed to be started from some sort of OpenStack
management app, *not* from virsh.
Yes, it's not recommended to start Nova instances behind its back using
Libvirt/virsh.
