Need some assistance concerning HVM guests and VLANs

[brook%biology.nmsu.edu@localhost (Brook Milligan)]

I'm pretty certain that the setup goes something like this (using fxp0
as the real network interface for dom0):

     dom0:
     # ifconfig fxp0 up
     # ifconfig vlan0 create
     # ifconfig vlan0 vlan 6 vlanif fxp0
     # ifconfig vlan0 10.0.0.10/24
     # ifconfig bridge0 create
     # brconfig bridge0 add vlan0 up

     domU:
     network setup as usual with xennet0, etc. same as without vlan
     i.e., _no_ knowledge of vlan within domU

The key point is to bridge the vlan device (not the real interface) to
the bridge used by the xennet devices.  Everything connected to that
bridge will not have tagged packets.

Note that I have never done this with FreeBSD, but would assume that
since packets on the bridge are not tagged that it need not know
anything about vlans either.

Cheers,
Brook
