One stupid question: I tried: xl vcpu-list Name ID VCPU CPU State Time(s) CPU Affinity Domain-0 0 0 3 -b- 74.8 any cpu 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 Domain-0 0 5 1 -b- 7.4 any cpu windows 2 0 3 -b- 27.8 1-5 windows 2 1 4 -b- 23.5 1-5 windows 2 2 5 -b- 24.9 1-5 windows 2 3 1 -b- 27.3 1-5 windows 2 4 1 -b- 25.2 1-5 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. -- Pavel Mateja
