Hi All,

I am a newer for Xen and Linux.

I am wondering if I could install Xen to PC directly without any OP has installed. Or must I install a linux on PC before install Xen? Somebody told me that I can install Xen as a OP.

They were probably talking about xenenterprise. It is a minimal linux distro with management tools for xen. But you do need a dom0 either way you look at it there is a base operating system. The difference would be installing the xen packages on top of your favorite distro and turning that into your dom0 or just using xenenterprise.

That's right. Citrix Xen Server has a few editions (express, standard, enterprise, etc.). Express is free (in cost). They all install directly on bare hardware.

You can also install Xen (choose the virtualization option) during the Fedora (not fedora 9 since no dom0 support), probably also centos, and I think opensuse, installation processes and you only get a Xen kernel and don't have a normal Linux kernel installed automatically. The normal userspace (of some kind) is still there and a dom0 (Linux, Solaris, *BSD) of some kind is always needed.

Cheers,
Todd
