Hello,

        I have Xen running with domUs in different VLAN's. I have xen on a
debian sarge server. My configuration is:

* In dom0, I have a bridge for each vlan (different than the native vlan
of interface eth0, that I don't need to tag). For each vlan the
configuration is (for vlan 302):

vconfig add eth0 302
/etc/xen/scripts/network-bridge start netdev=eth0.302 bridge=xen-br302
antispoof=no
/sbin/ifconfig eth0.302 up

* In the domU the configuration I have is:

vif = [ 'bridge=xen-br302' ]

* The only problem is that un domU I have to run "/usr/sbin/ethtool -K
eth0 tx off" after bring it up.
You don't have problem with UDP ?
Have you DNS or DHCP services running in your  VMs ?

For my own I loose UDP traffic If I try to setup one vlan per bridge in the DOM0
To resolve this I must setup VLAN in each  VM

Have you test bonding + vlans ?

Regards
