The Xen hypervisor does not have any concept of kernel modules or
runtime code modification / loading.

The method by which you insert some code into or make some modification
is to modify the hypervisor code directly.

Perhaps if you explain your actual end goal you can be better advised.

Or perhaps you/your supervisor are thinking of the dom0 guest operating
system which may have a module loading system (e.g. Linux does). This is
nothing to do with Xen though.

Thanks,
Ian.
