Depending on the size of your disk you may be able to copy your existing
system to a file and use that as a guest.

Without kernel changes?? I thought the guest OS needs be recompiled to be used under Xen as a guest OS.

The guest does not use the kernel from the guest filesystem. It uses the
vmlinuz-2.?.??-xenU kernel from dom0 file system but it uses the modules
from its own file system so you need to copy
the /lib/modules/kernel-version modules that are supplied in the xen
binary package or that you complied, to the guest filesystem.

Hope I don't confuse things more :-)

Oh yes you did :-)

So for example i want to use Centos 3.4 as a guest OS, how would I go about please? Let's say I have 1 Centos 3.4 ISO file.
