Tim,

I can't get an HVM domU to finish booting.  dom0 and domU are both running
64-bit SLES 10-beta10 with uniprocessor 2.6.16.13 kernels.  The domU gets
as far as running grub and loading the kernel and initrd but then hangs.
xentop shows the domU running at 100% CPU.

For what its worth, I have tried all combinations of the pae, acpi, and
apic options.  With pae=1 the domU dies (I assume qemu either exits or
dies).  With pae=0 the domU hangs as described regardless of the settings
of acpi and apic.

The machine has four sockets with Intel Xeon 7020 (2.66 GHz dual core with
hyperthreading).  Here is the config file for the domain:
(See attached file: hvm1.cfg)

Any other info you need?  Anything I should examine or try?

Steve D.
