Hi Rudi,

I have not assigned names to the virtual interfaces. They appear in
ipconfig with autogenerated names (eg.vif59.1 for the second NIC on the
VM with an ID of 59).

Here is the result of "ifconfig vif59.1":
[root@mrhappy ~]# ifconfig vif59.1
vif59.1   Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:32
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

Do I need to assign the Vifs a name?

Thanks again,

Rob Dunkley

have you assigned names (like vivwin1, vifhost1, etc) to each
interface in the config files? I read somewhere that this is a

What happens if you do a "ifconfig vifhost1" - if "vifhost1" is the
interface of one of the domU's?
