Re: [Xen-users] DHCP problem when changing motherboard

Evan Lavelle wrote:

What I think has happened is that the existing fc8-xen on my hard drive is confused about the network hardware on the new motherboard (a Dell R200 server). When the new board originally booted up, networking was disabled, but I fixed this by aliasing eth0 to eth3. The (old) driver seemed to have identified the new NICs at eth3 and eth4, rather than eth0/1.

How about changing the udev rules to reset your interfaces to eth0 and eth1 ?

Typically /etc/udev/rules.d/z25_persistent-net.rules contains lines like :

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="aa:bb:cc:dd:ee:ff", NAME="eth0"

When you change hardware, udev will see the new MAC address and create rules for the next available interfaces. Just change eth3 to eth0 (or whatever the correct arrangement is) and after reboot you'll have the same interface names you originally had.
