Hello all,
This is a custom network script I have been working on, mainly
for a SuSE 9.3 box, but I am hoping other people may find it
useful.
It is based on the existing network script in /etc/xen/scripts/ .
The existing script, by default, uses eth0 and xen-br0 for the
device and bridge respectively.
The custom script just takes one parameter, say eth0. It move
eth0 to one side by renaming it to eth0slv (eth0 slave) . Then
it create a bridge with the name eth0. Thus eth0 is magicallly
changed from an oridinary network device to a bridge.
This idea is shamelessly stolen from the /usr/lib/YaST2/bin/start-uml .
(I used the names eth0 / eth0slv . This might have been a mistake.
The start-uml script used eth0 / hweth0 . )
Doing things this way means that your firewall and routing settings
work both before and after the script is run. The network devices
continue to get configured with the info in /etc/sysconfig/network/
as usual.
To use it, you need to edit /etc/xen/xend-config.sxp . Set the
variable network-script to point to this script. Set the
variable vif-bridge to be the name of an existing network device
(probably eth0).
The script is a still a bit rough. I haven''t finished commenting it.
There is still debugging stuff left in place. Feedback, both good
and bad, is welcomed.
