I have 4 guest VMs installed on 1 host. One of them is
Vyatta (VC5). Currently we are using default Xen-bridge for
communication between VMs(inter-domain or intra-domain).
I want to assign Vyatta(a guest VM) exclusively to replace Xen-bridging for VM
to VM communication.
Means the traffic sent from guest-1 to guest-2 bypass briging and route through
vyatta(VM), instead of going to Dom0.
As William Von Hagen says in his book ''Professional Xen
Virtualization''
"The choices provided with a standard Xen installation are the following:
❑ network-bridge: Bridged networking (the default)
❑ network-nat: NAT networking
❑ network-route: Routed networking
If you don’t want to use one of the out-of-the-box approaches to Xen networking,
the network-script parameter can also be set to the name of your own
configuration script. If you need to extensively customize one of these scripts,
it’s a good idea to make a copy of the default script with a different name in
the /etc/xen directory, configure the Xen daemon to use your new script by
changing the value of
the network-script parameter to the name of your new script, and then modify
the copy. This enables
you to keep a pristine copy of the original script on your system for reference
purposes as well as providing a copy for your modifications."
Tell me some way where and how to chance xen ''network-script''
parameters?
In fact i want to change bridge network script available in /etc/xen/scripts or
write my own script in terms of vyatta. Give me some idea to which extent i have
to change the scripts?

Re: [Xen-users] Fw: Vyatta VC5 inplace of Xen-bridging.
Please don''t resend your email if you don''t have any additional info. We got your first mail just fine.

I suggest you either : - install vyatta on dom0, or - treat domUs like any other physical server. On normal server, you''ll have vyatta bridging traffic from (for example) eth1 to eth2. Do the same thing with Xen setup: on dom0 you have two bridges (for domU''s eth1 and eth2), while vyatta domU itself has a bridge. Another alternative is to use domU as backend/priviledged domain. Something like this http://lists.xensource.com/archives/html/xen-users/2005-05/msg00345.html This tend to be more complicated though, and I haven''t tried it personally. I''d prefer to stick with standard bridged setup. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
