Hi,
I use ‘xl network-attach’ to attach a nic,
but failed.

If succeed to attach，’brctl show’
will output:

Cannot find device "vif6028.0-emu"
I trace /etc/xen/scripts/vif-bridge，find it is /etc/xen/scripts/xen-network-common.sh:88, failed to execute command
‘ip link set dev vif6028.0-emu down’，then
output ‘Cannot find device "vif6028.0-emu"’
82 # configure interfaces which act as pure bridge ports:
83 _setup_bridge_port() {
84 local dev="$1"
85 local virtual="$2"

90 if [ $virtual -ne 0 ] ; then
91 # Initialise a dummy MAC address. We choose the numerically

96 fi
97
98 # ... and configure it
99 ip address flush dev ${dev}

Anyone have an idea?
Thanks!
