>=3B Was this just = the tail of the log or the complete thing?

No it was in the midd= le . I am attaching xen-hotplug.log.gz

>=3B >=3B So for some reason the hotplug script has been unable to rename th= e
>=3B interface=2C apparently because it is busy.
>=3B
>= =3B Based on some local experiments it seems that busy might be because the=
>=3B interface has already been brought up. vif-bridge is changing th= e name
>=3B before bringing up the interface=2C perhaps something else= in your system
>=3B (some bit of openstack perhaps) is also trying to= manage this device and
>=3B has configured it?
>=3B
>=3B I= 'm out of my depth wrt the openstack side of things now I'm afraid.
