Thanks for the advice on how to set up the domains interfaces :-) The relevant line in the domain config was set to vif=['ip=10.0.0.1,mac=<MACADDRESS>'] - that's as per the manual I think?. Neither had any effect on what ifconfig actually (this is on Xen 3.1.0 btw).
Cheers,
Alasdair

Yes, you can setup a dummy0 device in Dom0 to be used for this purpose.
1. Create the dummy0 network interface device (as simple as creating a
network device and loading the dummy module appropriately) - this process is
of course distro specific
2. Specify the (network-script 'network-bridge netdev=dummy0') in
xend-config.sxp. If you need other accesses you will need to setup a custom
script that handles that.
3. use the appropriate vif=['bridge=xenbrX'] for the guest config.

Setting the IP I have often had to do manually in the guest to match. I am
not sure if this was/is a bug or is by design.
