Qemu Networking - Connecting VLANs to TAP devices

[Victor Dorneanu <victor%dornea.nu@localhost>]

Hi there!

Is it possible to connect multiple VLANs  together and connect 1 of
those VLANs to some TAP device, so "Qemu Guest 1" can access "Qemu Guest
2"? I'd probably to that this way:

        $ ifconfig tap0 create
        $ ifconfig tap1 create
        $ qemu -net nic,vlan=0,macaddr=52:54:00:12:34:56 -net 
tap,vlan=0,ifname=tap0 -cdrom [iso file]
        $ qemu -net nic,vlan=1,macaddr=52:54:00:12:34:57 -net 
tap,vlan=1,ifname=tap1 -cdrom [iso file]
        $ ifconfig bridge0 create
        $ brconfig bridge0 add tap0 add tap1



After setting up network on both guests, then I should be able accessing
"Guest 1" and "Guest 2". But how do I configure both guests in order to
allow connectivity between them ("Guest 1" <---> "Guest 2") ?! Do I have
to use TCP-Sockets?!

Is there any simple way to realize this scenario using TAP devices and
*no* sockets?!

Thanks.
