[Xen-users] VLAN configuration

[Laurent Jouannic <laurent.jouannic@xxxxxxx>]

Hi to the ML.

I'm new to VLAN configuration, and combining it to XEN is a bit difficult.

I want to use VLAN because it's possible to "arping" from a domU to an 
other, and VLAN looks like; the only solution to prevent that.
May be I'm wrong if someone got a solution, I may be interrested. I've 
also tryed ebtables, but nothing to prevent arp question: who-as IP¨.
The configuration I need is:
 -------------
 |   domU      |
-| -[ dom1 ]-  |-
| -[ dom2 ]-  |
 -------------

I want dom1 and dom2 to use eth0 and eth1, with vlan interface.

I've tryed 
http://lists.xensource.com/archives/html/xen-users/2007-03/msg00988.html 
configuration, but I have the following error:
WARNING:  Could not open /proc/net/vlan/config.  Maybe you need to load 
the 8021q module, or maybe you are not using PROCFS??
Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config
ERROR: trying to add VLAN #2 to IF -:eth0:-  error: Invalid argument
ERROR: trying to add VLAN #3 to IF -:eth0:-  error: Invalid argument

The machine run on Debian Etch and the vlan package is intalled.

If you have some ideas, I'm stuck!!!
Thanks.


Laurent.
