Re: [Xen-users] using 4 lan cards how many bridges needed

[Tapas Mishra <mightydreams@xxxxxxxxx>]

Well I am going through this page
http://wiki.xensource.com/xenwiki/XenNetworking
lets see if some one comes up.
I right now have changed the bridge name but the same does not seems to reflect.
In the file /etc/xen/xend-config.sxp
I tried to have a bridge of my name so I edited them as follows

# The bridge is named xenbr0, by default. To rename the bridge, use
#
# (network-script 'network-bridge bridge=<name>')
#### Tapas made changes
(network-script 'network-bridge bridge=tapas')

I did rebooted my server but then when I do brctl show
bridge name bridge id STP enabled interfaces
eth2 8000.0026b9824238 no peth2
I can not rename it.
The wiki page mentions that in Xen-3.3 the default name of bridge is
same as your interface is but I am using xen-3.2.
