No it's not that simple. You would have to compile that 2.4 kernel
to work with Xen. It's is not a matter of just tweaking a config file !

As I've mentioned before: the guest OS, i.e. the one running as a domU,
also needs a specially compiled kernel. See
This is because Xen is a paravirtualizer instead of a full virtualizer,
Until Xen3 and the new generation of Intel and AMD CPU offering hardware
support. Check the roadmap for Xen3 at the bottom of
Wouldn't it be better to ask questions like this on the xen-users
The lack of responses here seems to indicate a general lack of knowledge
in this topic...
The suggestion is good, but it's not there is lack of knowledge, rather
that it's 1/ hard 2/ work on old code 3/ would break his RHEL3 support anyway
and there is just too many thing to do to get Xen working smoothly on
