Thanks Rene, I'll look into your suggestions.
I don't think it's a conflicting MAC as there is only 1 guest, but
will check it out.
Would you advise running the engine and nodes on a separate network
range to my existing network rather?
Thanks.
Regards.
Neil Wilson.

Hi Neil,
I had a similar issue with my oVirt environment with some vms.
The issue on my side was oVirt and RHEV environment in the same subnet
and conflicting MAC addresses on some vms (as both use the same MAC
range and I didn't change this with engine-config).
So can you check if this MAC our your vm is in use by an other host/vm
(maybe from a KVM installation)?
