VmError: Device 0 (vif) could not be connected. Backend device not found.
My vm01 config is as follows:
kernel = "/boot/vmlinuz-2.6-xen"
memory = 32
name = "vm01"
nics = 1
dhcp ="off"
vif = [''mac=AA:00:00:18:98:FB, bridge=xenbr0i,
vifname=vii1.0'']
extra="selinux=0"
disk = [''file:/root/xen/centos.4-2.img,sda1,w'',
''file:/root/xen/centos.swap,sda2,w'']
root = "/dev/sda1 ro"
