In addition to that the CentOS kernel is not compiled with CONFIG_IP_PNP so having a DomU with
the ip set in the config file will never work. It will if you recompile the kernel or use a different OS like Debian in the DomU.
The CentOS kernel does pay attention to the MAC address assigned in the DomU config file though so you
can set up a DHCP server with that MAC in it and it will assign the IP you want.
