Ambitious!  Note that older operating systems often don't work in
qemu, not for any particular reason but just because they don't get
much attention and things regress, drivers in particular.  Or the
drivers such as IDE don't emulate corners which are needed by the old
OS.  For example I tried running some really ancient Linux versions in
qemu a while back with no success at all.

Having said that I have run RHEL 3 recently on qemu and that's fairly
similar to 2.1.

When you say you "tried to change the XML file" - how did you do that?
You should use ‘virsh edit <guest>’ only, and not attempt to edit any
XML file directly.  Or of course you can use virt-manager as the other
reply suggested - it essentially does the same thing as virsh edit.

You might also try to install using --location, assuming that RHEL 2.1
supported that (I don't recall, but I'm pretty sure RHEL 3 did).
