The xen in SLES10-beta 1 is known to not work.  It has trouble booting
on SMP x86-64, and VMX doesn't work.  Beta 2 or beta 3 (which was
released today) are much better.

Updating your beta 1 installation with newer xen-* and kernel-xen RPMs
may get you started (get them from beta 3 or the Xen Technical Preview
site).  Better, of course, is to do a full reinstall with the latest
beta.

We've got VMX working in the lab.  Have you tried disk images from
free.oszoo.org?  That would make a good test corpus, so we can reproduce
problems here with the same disk images.

Other known issues to watch out for:
* We're testing VMX using SDL; we haven't had time yet to troubleshoot
VNC.
* 32 bit unmodified guest doesn't work on 64 bit hardware with VMX.
* Make your NICs in domain 0 start at boot time; don't use "manual" or
"ifplugd" in your /etc/sysconfig/network/ifcfg-eth* files, or domain 0
may lose its IP address when xend starts.  Will be fixed in beta 4.
