xen discuss - Aug 2008 - Bridging to vlan interface?

Hi,

I''m using opensolaris 2008.05, updated to snv_94. On dom0, I have :
- bnx1 connected to switch as trunk
- bnx128001, vlan 128 on bnx1, allocated an IP address and serve as 
dom0''s primary network interface.

I created a RHEL5 domU with this vif config
vif = [ ''mac=00:16:XX:XX:XX:XX, bridge=bnx128001'' ]

but domU startup failed with
Error: Device 0 (vif) could not be connected. Backend device not found

If I changed vif config to
vif = [ ''mac=00:16:XX:XX:XX:XX, bridge=bnx1'' ]

domU boots correctly, and I can setup vlan interface on domU. So the 
question is, how can I setup opensolaris dom0 to pass the vlan interface 
(bnx128001) to domU instead of passing the trunk (bnx1)?

Regards,

Fajar

This doesn''t work today.

When the Crossbow project integrates (later this year) it will be
possible to create VNICs over VLANs. Until then you''re out of
luck. Sorry.
