My scenario was the following - host: C5.2/x86_64, fully updated. Needed to run Win XP/32 as VM, with full access to the parallel port given to a very special Windows driver (which controls a development board) - in the guest we have to run a commercial tool based on Eclipse (Java). With stock xen, I was unable to transfer control of the parallel port to the guest. It simply did not see the port, no matter what I have tried With xen-3.3 from gitco and the same xen config, the port was correctly identified and could be used from Windows. On the other hand, Java started to consume 99% of the CPU making the VM impossible to use. See also http://lists.centos.org/pipermail/centos-virt/2009-February/000836.html
