Hi there,

I assume your dom0 OS is running something like RHEL5 and you're using the 
default RHEL Xen packages, plus the virt-manager GUI.  Is that right?

virt-manager is very good for installing RedHat-like guests - for instance, 
RHEL, CentOS, Fedora, etc.  There are a number of possibilities for the 

- give virt-manager a network location from which the install may proceed; 
it'll then launch a guest which will configure networking and then install 
from that location

Fully virtualised:
- give virt-manager a filessytem location for an ISO CDROM image file, which 
may be used as a virtual installation CD.
- give virt-manager a device name for your real CDROM drive to install from 
physical media

Hopefully the information above will be useful to you.  If it's not enough, 
we'll need some more information from you including:

* What tools you're using (virt-manager or other, RHEL dom0 distro or other, 
* What exactly you've done so far.
* What happened (what output / error messages you saw, where things are stuck)
