Default XEN server (PLEASE HELP)


I had XEN server and because of RAM I decided to change the hardware so i moved the SATA HDD to new system and turn on the system and the server comes up but there was no nic then i found the nic name has been changed to eth1! then i went to /etc/network/interfaces and change the eth0 to eth1 and then i reboot the server to be sure after when i login to server and used ifconfig i see:

#ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:16:76:bd:10:54
inet addr: Bcast: Mask:

this is just a guess but you can try it

go to the following file

And change:
(network-script network-bridge)

(network-script 'network-bridge netdev=ethX')

ethX the interface you want to use (eth0 or eth1)

be sure to use the same in interfaces on the guest host.

and you should need to restart Xen or the whole machine if you want.

Hope this helps, as i said its just a long shot guess
