Are you using bridged networking? I think it has something to do with that as well as not having a DHCP server in my network.
Actually, yes. I use a bridge to connect to the lan, where guests obtain addresses thru DHCP, but I have no issues assigning addresses by hand either.
That host machine has at least two nics. One for the host, and one shared/bridged for the guests.
If there's any config files you're interested in seeing, I could post them.
