I found the manual very useful. https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualization-en-US/index.html
Installation of RHEL5 Virtualisation went smoothly for me - and I'm a complete novice. Just make sure you have an installation number that gives you virtualisation and select it when promted during the install. I installed from CD1 and had the other CD ISOs available on an NFS so did a Linux Askmethod and pointed to the nfs. For the guest installs I found all the defaults work fine and all you have to remember to do is the "xm create /etc/xen/<guest-name>" at the end. I used the Virtual Machine Manager gui and specified an Install Tree on the local server which had been constructed by consolidating all the CDs as a DVD ISO and exporting via NFS. That is then referenced as "nfs:<local-ip>:<mount-point>" which I didn't find much help on in the docs I agree. You can then optionally use a kickstart file but I'd recommend not to, to keep things simple if you are having problems. There's a couple of gotchas though. You obviously need to configure NFS and if you have iptables enabled (which it is by default) you will need to open that up, which means fixing the nfs port numbers which is quite fiddly. Alternatively turn off the firewall. I also found that SELINUX got in the way of guest installs which were done to file rather than disk, unless they go into /var/lib/images or something. Couldn't find that documented either, but you just have to modify the context of the desired location using semanage and restorecon. (Or switch off SELINUX) I found that guest installs to raw disk took 30 mins and to file they took 2-3 hours! And finally - if you are installing a guest to raw disk make sure you partition it first so you install to /dev/sdb1 for example instead of just /dev/sdb as I found that lead to big problems when the underlying system was rebooted. It picked up the / label from a guest instead of the Dom0. This is only a problem if you are manually partitioning the guests - if you leave the LVM defaults you wont get caught by this.
