[Xen-users] Trouble creating DomU with 2 NICs

[Alan McKay <alan.mckay@xxxxxxxxx>]

Hey folks,

I created a DomU, installed Linux, and then realized I'd only given it
1 NIC so brought it down to edit the cfg file to give it another NIC.

Originally I just had :

vif = ['']

And so I guess the defaults worked for the 1 NIC.   So I changed it to :

vif = 
['mac=00:1e:68:8e:31:b8,bridge=xenbr0','mac=00:1e:68:8e:31:b9,bridge=xenbr1']

Where those MAC addresses are from the bridge in dom0, as seen here :

My Dom0 has :

But when I try to bring this up I get :
