You should never give 127.0.0.1 to the virt-install/virt-manager. It 
would start up the installation, but wouldn't continue further. The 
problem is that after the installation is started up, anaconda in the 
guests looks for the distribution at 127.0.0.1 which is local to the 
guest and there won't be an installation tree available there. You 
should always give the ip address of dom0 instead of 127.0.0.1.
