Hi all.

What is the canonical way of getting xen to fully work with 802.1q (vlans) ? After (re)searching i found many ways but so far none is working.

platform is gentoo (x86/32) and netwerk card a tg3. xen is v3.

my config is as follows ...

eth0 is  simply up (with no ip) and i created several eth0.x interfaces corresponding to several vlans.
eth0.10 is de 'default' vlan (i.e. default gw).

what i want is a way of each DomU connect to the world thru it's vlan bridge.

for instance ... for a domU i defined   bridge=xenbr0.10. and in /etc/xen/xend-config.sxp i defined

(network-script my-network-scripts)

contents of /etc/xen/scripts/my-network-scripts bellow

set -x
dir=$(dirname "$0")
"$dir/network-bridge" vifnum=0.25 start
brctl addif xenbr0.25 eth0.25
"$dir/network-bridge" vifnum=0.10 start
brctl addif xenbr0.10 eth0.10

but i allways get an error saying that i need to increase the number loopbacks because i have reached the limit. Fact is that the limit is way higher 'cause i increased it (sucessfully) to... 100.

What am i doing wrong ?

Many Thanxs in advance

Best Regards
