Re: [Xen-devel] question about network setting for domain1
You don't need an ifcfg-eth0 file in dom1. We pass in the IP config on
dom1's command line, and the interface will automatically be set up.
What is happening is that your ifcfg-eth0 file is overriding the
settings passed in on the command line. Because you do not specify a
gateway in the file, no default route is set up and so dom1 cannot
send packets outside its subnet.
