As I've mentioned before: the guest OS, i.e. the one running as a domU,
also needs a specially compiled kernel. See
http://wiki.xensource.com/xenwiki/XenFaq#head-bb579ddda3999d87064a36b7d847fad8e39440ae

This is because Xen is a paravirtualizer instead of a full virtualizer,
like VMware.

Wouldn't it be better to ask questions like this on the xen-users list?
The lack of responses here seems to indicate a general lack of knowledge
in this topic...
