Yeah, the offending patch in RH-BZ 1422413 appeared in qemu 2.8.
So it would make sense to work with newtwon (2.6.1), and pike (2.10), but fail on Ocata (2.8).
I checked the ppa, in general it seems to work for me, so I'm now waiting for your verification if that really addresses the issue you are facing.
If that would be the case I can pass it through regression tests and afterwards to SRU (which currently holds another update that has to clear before doing so)

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

[ + ] neutron-lbaasv2-agent
[ + ] neutron-metadata-agent

and have also restarted and checked the nova-compute logs for their
neutron counterparts.

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.
