Hello,
I have installed the openvswitch kernelmodule  on debian with xen .
I have Problems setting up a mirror Port on OpenvSwitch.
Here is what i try:

$ovs-vsctl list port
...
_uuid               : a7fd3df2-d7bf-4a92-8133-22d9e7528338
bond_downdelay      : 0
bond_fake_iface     : false
bond_updelay        : 0
external_ids        : {}
fake_bridge         : false
interfaces          : [cc7f02ab-614e-41c7-80eb-85af352a448c]
mac                 : []
name                : "vif8.0"
other_config        : {}
tag                 : []
trunks              : []
...

$ovs-vsctl create mirror name=mirror3 select_all=1  
output_port=a7fd3df2-d7bf-4a92-8133-22d9e7528338
$ovs-vsctl list mirror
...
_uuid               : aaa7fe43-c75f-4fc8-bf6e-03aab55019aa
name                : "mirror3"
output_port         : a7fd3df2-d7bf-4a92-8133-22d9e7528338
output_vlan         : []
select_all          : true
select_dst_port     : []
select_src_port     : []
select_vlan         : []
...

The problem is that tcpdump in the vm on vif8 does not catch anything  
unusual (i want to see intervm traffic for an IDS sensor).
this might have a simple solution, but i dont know what else to do.

next question is how to delete a mirror port : )

thanks

Mike
