[Fedora-xen] Confused on how to have each guest reach a VLAN

Both my host and guests are Fedora 6. My first, naive thought, was to
just configure eth0.N within each guest OS.
For testing purposes, I created eth0.69 both within guest01 and guest02,
with addresses 10.11.12.101 and 10.1.12.102 respectively. But guest01
and guest02 can't ping one another through these new addresses.
I read http://wiki.xensource.com/xenwiki/XenNetworking and, in its last
paragraph, it suggests I have to configure VLAN in the host OS, and add
virtual interfaces to a bridge. But I'm confused about how to do that.
Which interfaces do I have to create? Do I have to add them to the
xenbr0 bridge? Can I have this start automagically upon "xm create"?
Below are my ifconfig on the host machine, and the config files for the
two guests (they have IDs 5 and 6):
