I do not know anything about cpuid setting, google searchs returned some
patches to xen, but none of them with something that I can learn how to

Other google searchs on the 0x3e error returned group messages with
people having this problems with the first HyperThreading Intel
processors, the suggestion for then was always disable HT on BIOS.

Just to check, i ran a Linux CD instead of the Windows NT Install on the
same machine, here follows the /proc/cpuinfo of that boot:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 23
model name      : Intel(R) Xeon(R) CPU E5430 @ 2.66GHz
stepping        : 6
cpu MHz         : 2666.744
cache size      : 6144 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 10
wp              : yes
flags           : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca
cmov pat clflush mmx fxsr sse sse2 constant_tsc pni ssse3 cx16 sse4_1
bogomips        : 5340.58
clflush size    : 64
power management:

I noticed that there is no "ht" flag, but if there is a way to make the
HVM guest to see a Pentium II, Pentium 3 or even a first of the Pentium
4 processors, I think it will solve my problem.
