Am I doing something wrong? If I remove the second bridge (xenbr1), the
domU boots fine. If in place, it causes the following crash and brings
down another domU with it.
[root@teegeeack xen]# cat theta
kernel ="/boot/vmlinuz-2.6.12-1.1454_FC4xenU"
memory = 128
name = "theta"
nics = 2
vif = [ 'bridge=xen-br0', 'bridge=xenbr1' ]
disk = ['file:/theta.img,sda1,w']
root = "/dev/sda1 ro"
extra = "selinux=0"
Bringing up loopback interface: [ OK ]
