That won't work. Basically virt-install and RHEL/Centos installer issue.

You can't. Not directly.

That SHOULD work. Perhaps some IP range or path mixup?
IMHO, the easiest way is to simply use http. Something like:
- install httpd on your dom0
- create /var/www/html/iso
- mount your ISO there
- use http://ip_of_your_dom_0/iso as installation source.

Again, you can't. Opensolaris can do it just fine. RHEL/Centos
currently can't do it when installing as PV guest, thus the http
workaround needed.
