Re: [Xen-users] Xen Hotplug Issues

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

Okay, that's solved, but I'm hitting another issue, now.  When I start VMs, the 
MAC address of my dom0 is changing to some very random addresses.  One of the 
systems has had all of the following MAC addresses over the past three days:
b8:ac:6f:a3:e:e5
96:15:8b:65:4e:b8
82:30:42:d9:a6:79
5e:9:f3:fa:a1:7c
b6:cc:c:42:44:70
72:40:f7:66:8e:72

The first one is the real MAC address of the system, the next five are 
seemingly random MAC addresses that don't correspond with either the host MAC 
address or the VM MAC address.  It seems to be using these MAC addresses in 
dom0 for the DHCP-assigned address on my bridge.  So, it isn't as if interfaces 
are being added to the bridge and they're picking up new IP addresses, it's as 
if the system is sending out packets of some sort with a source IP address the 
same as the bridge, but with several different MAC addresses.  Any hints would 
be greatly appreciated.
