One stupid question:
I tried:
xl vcpu-list
Name                                ID  VCPU   CPU State   Time(s) CPU Affinity

Domain-0                             0     1    2   -b-       7.7  any cpu
Domain-0                             0     2    5   -b-       7.4  any cpu
Domain-0                             0     3    2   -b-       8.2  any cpu
Domain-0                             0     4    0   r--       8.4  any cpu

Do the last two lines mean that two vCPUs in winows are running on one real?
The output changes and mostly is real - virtual cpu mapped one to one.
I have to study the pinning more. I guess I was wrong when I wrote I already 
have it.
