PS--I should say that in regards to my original question,
if I have two bridges already running on my dom0, it
is possible to install the domU with just one, and then
add the second one post-installation and that works just fine.
I am just wondering if it's possible to use virt-install to
get them both installed from the start.

Hey Steven
OUt of curiosity, what is you dom0 configuration (OS and xen ver.)
I'm struggling to put 2 NICs (& 2 bridges) on a CentOS52 x64, running gitco xen
3.3.1.
Cheers,
N.

Subject: [Xen-users] installing DomU with two network bridges viavirt-install
I have a Xen DomU configuration that was made in the days before
libvirt and virt-install. In this configuration
I have:
vif = [ 'mac=00:16:3e:05:06:01, bridge=xenbr0', 'mac=00:16:3e:05:06:0a,
bridge=xenbr1' ]
and then in xend-config.sxp I define
(network-script my-network-bridge)
where my-network-bridge is in the scripts directory and looks like this:
[root@fermigrid6 xen]# more scripts/my-network-bridge
#!/bin/sh
# start bridges on both eth0 and eth1
XENDIR="/etc/xen/scripts"
$XENDIR/network-bridge "$@" netdev=eth0 bridge=xenbr0 vifnum=0
$XENDIR/network-bridge "$@" netdev=eth1 bridge=xenbr1 vifnum=1
Is there a way to automate all or part of this with virt-install?
I'm guessing that I would still have to hack the xend-config.sxp
to get xenbr0 and xenbr1 started on dom0 in the first place,
but once that is done, would it be possible to have
two network interfaces specified via the --bridge argument
of virt-install, where one would have --bridge=xenbr0 and the other
would have --bridge=xenbr1?
Thanks
