I'm not in the context, but still have some comments here :-).
Basically we *can* boot a SMP kernel in a UP VMX domain. To boot up a
SMP kernel, we need vcpus > 1, acpi = 1 and apic = 1 in the config file,
or you are just running a UP VMX domain.
Some old version Linux SMP kernel can *not* boot in a SMP VMX domain,
but the root cause is PAE support code, which is mixed with SMP code in
Linux kernel :-(, newer version Linux, like 2.6.12+, should work.
Actually we have a fix to this PAE issue, but more tests needed.
