DomU's on different vlans

I was wondering if anyone knew of a decent primer or documentation set for
configuring multiple vlans using trunk ports in Xen on SLES10sp2. I have
read this cool solution:
http://www.novell.com/communities/no...ecommendations
extensively and in doing so have learned a lot about Xen networking but I
am still unable to get my 802.1q port working inside Xen. I can
successfully configure it without Xen and I have multiple VLAN's and IP's
on a single NIC working but once I try to create a bridge things get
confusing and it stops working.

There seems to be some notes out there regarding setting it up on Debian
based distros on Xen 3.0 but I have yet to find anything useful that
translates over to SLES10sp2 well. Any tips or help would be much
appreciated.

Thanks,
