[Xen-users] second NIC MAC address for domU

["Jonathan M. McCune" <jonmccune@xxxxxxx>]

Hello,

I have a server with two NICs running Xen 3.2 from Debian Lenny (eth0 
and eth1).  I'm wondering what the best method is to effectively 
dedicate eth1 to a particular domU.  I have an existing DHCP entry for 
the MAC address of eth1, so assigning a different MAC to the virtual NIC 
in my domU and bridging that to eth1 within dom0 is an issue for me.  I 
tried assigning the identical MAC address to my domU in the vif line in 
its config file.  tcpdump in dom0 suggests that the DHCP requests are 
making it out onto the network, but the DHCP replies don't seem to be 
getting through to the domU.
I've also observed that it's possible to dedicate a PCI device to a 
particular domU with pciback, but the necessary module is not part of 
the stock kernel and I don't want the maintenance overhead of having to 
keep rebuilding a particular module, etc.
Should I be doing this with a routing-based configuration?  Performance 
would be nice but this server is not heavily loaded, so I'm not too 
worried about performance.
Thanks for any suggestions,
-Jon
