dom0 MAC address

Tim Freeman
The network card's MAC address in domain 0 is showing up as different from
native Linux.  Is there a way around that which will work at boot time? The
environment here requires them to be identical to get the correct IP address via
DHCP. This is Xen 2.0.6.

Thanks for any insight,
Tim

eth0 and eth1 were getting flipped.  I was on my way to adjusting the MAC in
if-pre-up when I realized the new one doesn't even work ... woops.

Thanks,

That's pretty surprising given that we leave linux to do the pci
probing, so the result should be the same as the equivalent native Linux
version (though Linux has flipped the order between certain version).
Are you sure you have drivers for both cards in the kernel?

Yeah, that was the problem, the driver for the fancy card is only in native
Linux, so "flipped" is incorrect.

Thanks,
Tim
