Hi all,
While trying to sort out/test some patches, I was told that it's best
to create bridges manually in
/etc/sysconfig/network-scripts/ifcfg-xenbr*. I did this, commented out
(network-script network-bridge) and restarted the network and Xen.
With the bridges manually in place, and no longer having 'pethX'
devices, I tried to provision a VM and it failed with:
====

Thinking that I still needed to use '(network-script network-bridge)',
so I put it back (actually, a modified version I will link below). When
I start xend after putting it back, I got such an incredible flood that
all network communications were lost on the network. Obviously, I'm
reluctant to randomly try things now.
So, if I manually build the bridges, how am I supposed to configure
Xen to use them?
Thanks!
PS: My modified network-bridge:
====
#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0
"$dir/network-bridge" "$@" vifnum=2 netdev=eth2 bridge=xenbr2
