Xen users - Jan 2009 - Xen 3.0.3, debian, bridging, bonding and vlans

Hello,

I have a debian server (etch version) running Xen 3.0.3 installed from
debian packages. In this server I have a bonding and I have defined a
few vlans, each on then running in a different bridge.

The problem I have is that I can run VMs in a VLAN different than the
default, that is, different than the interface without tagging, but I
can''t run a VM using the default bridge. I''ll explain
better...

I have different interfaces:

* bond0 (active-passive bonding with eth0 and eth2
* vlan10: Interface defined over bond0 tagging for my vlan 10
* vlan20: Interface defined over bond0 tagging for my vlan 20
* ... (more vlans)

I define a bridge for every vlan (I tried to define use all vlans over
the same bridge, but VM didn''t work). So I have:

* xenbr0: Default bridge. It is supposed that bond0 should be included
here.
* xen-br10: Bridge for vlan10. It includes interface vlan10
* xen-br20: Bridge for vlan20. It includes interface vlan20
* ...

I attach my /etc/network/interfaces where is defined all this
configuration.

I use the default network-bridge script included with xen, run from
"my-network-bridge", which is a script I use to launch network-bridge
over all the bridges I use.

With this configuration, I can run VM using bridges different than
xenbr0, but if I try to run a VM using xenbr0 bridge, its network
doesn''t work.

Any idea?

?!  You don''t need any network script if the bridges are set up by the
OS.  Stick to network-dummy, and specify the appropriate bridge in
your domU config.
