Xen users - Apr 2006 - compiled xen kernel, second processor and HT gone

I just compiled xen kernel on xen-3.0.1 on a dual xeon and now i only see a
single processor and that too without HT.

The only thing i changed in the default xen kernel config was changing the
CPU type from Pentium Pro to Pentium-4/Celeron(P4-based)/Pentium-4 M/Xeon.

Can anyone tell what could be wrong ? (donno if the cpu type change could
have caused this but since this is my first experience on a HT processor
with xen, can''t say)

Any help would be appreciated.

/proc/cpuinfo just shows one processor now. Trying to compile the xen0
kernel now. Will revert back with results.

Now it shows that xend is detecting 4 vcpus, however dom0 is geting to see
only 1 cpu (even /proc/cpuinfo under dom0 says the same thing). I have
(dom0-cpus 0) inside /etc/xen/xend-config.sxp.

any ideas ?
