With my setup, it's like this
# cat /proc/cpuinfo | grep processor
processor       : 0

# xm vcpu-list 0
Name                                ID  VCPU   CPU State   Time(s) CPU Affinity
Domain-0                             0     0     0   r--   93253.0 0
Domain-0                             0     1     -   --p     579.8 1
Domain-0                             0     2     -   --p      11.4 2
Domain-0                             0     3     -   --p       8.0 3
Domain-0                             0     4     -   --p       8.0 4
Domain-0                             0     5     -   --p      13.5 5
Domain-0                             0     6     -   --p      11.7 6
Domain-0                             0     7     -   --p      10.0 7

the benefit is that I can hotplug other cpus to dom0 if necessary later.

Hope you can solve this problem. When you do, please share your results.
