Did you already solve this?

I do text-based installations with virt-install, and follow this procedure:

- if you are going to do several VM installations, then before you 
install, copy the directories you need (for example 
centos/5.6/os/x86_64/) from a CentOS mirror to /var/www/html on the host
- start httpd on the host, check in the browser that you can access the 
CentOS files

- from a CentOS mirror, download any bootable iso (netinstall cd, or 
installer cd #1 do fine) to the host
- mount the iso using "mount -o loop"

- do virt-install
	- for "location", use the mounted iso
	- do a "http" installation using your local http "repo" (refer to the 
host with its public ip number; 10.0.2.2 did not work for me)
