First of all, are you using bridged setup or routed setup? If you use
bridge, you wouldn't need to specify ip, netmask, or gateway on domU
config file. Also, if using bridges setup, dom0 bridge IP address (in
your case it's called eth0) should be on the same segment as domU's
network interface. You're using two different segments.
