[Xen-users] (domU) Device 0 (vif) could not be connected. Hotplug scripts not working.

["BugOne S" <bugone82@xxxxxxxxxxx>]

Hi, i cant run domU, because of this error:

xen xen # xm create -c client1
Using config file "client1".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

my config file for the domU is:

kernel = "/boot/linux-2.6.12-xenU"
memory = 512
name = "domU"
# doesnt change error type if i uncomment or i comment the following line...
#vif = [ 'mac=aa:00:00:00:00:11, bridge=xenbr0' ]
disk = [ 'phy:sda1,sda1,w' ]
root = "/dev/sda1 ro"
extra = "4"

(like the default conf file...)

i also installed udev, hotplug, bridge-utils, sysfsutils like said in other 
thread with the same problem...
but nothing change...
what's wrong?
