xen0 is just another guest within xen, so its the same as with xenUs. Only one 
CPU for each guest.

from a dual xeon with HyperThreading enabled:

cat /proc/cpuinfo shows just ONE cpu (in xen0 and each xenU),

but "xm info" shows:
...
machine                : i686
cores                  : 2
hyperthreads_per_core  : 2
...

makes 4 CPUs total.

# xm list
Name              Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0           0      120    0  r----  14734.5
db01               8      511    1  -b---    275.6    9608
db02               3      511    3  -b---  13786.0    9603

Shows CPU's 0,1,3 in use with CPU 2 currently unused.
