I spent some time today trying to modify the ocata xml templates
produced in /etc/libvirt/qemu/<INSTANCE-ID>.xml for each of the
generated instances. Destroying & Undefining the existing instance,
making some changes and redefining the xml, however it appears that nova
regenerates these templates upon instance reset, thus removing any
changes made to the xml template. Is there any way to disable this
feature that does not require some serious modifications to the nova
underpinnings?

Bug description:
arm64 Ocata ,
I'm testing to see I can get Ocata running on arm64 and using the
openstack-base bundle to deploy it. I have added the bundle to the
log file attached to this bug.
When I create a new instance via nova, the VM comes up and runs,
however fails to raise its eth0 interface. This occurs on both
internal and external networks.

I have checked all services in neutron and made sure that they are
running and restarted in neutron-gateway

There are some warnings/errors in the neutron-gateway logs which I
have attached the full tarball in a separate attachment to this bug:

I'm not sure if the above error could be pertaining to the failure, I
have also attached those logs to this bug as well...

Should neutron-openvswitch be assigned to the 'nova' availability zone?
I have also attached the ovs-vsctl show from a nova-compute host and
the neutron-gateway host to ensure that the open v switch routes are
correct.
I can supply more logs if required.
