Hi,
I have a number of comments:
1. Will the user have any indication for the maximum amount of vCPU's?
2. What happens if a VM is already configured with the same CPU pin 
info? Will this be shared?
3. Would it possible to extend this to limit the MHz of CPU that can be 
allocated to a VM?
5. If the VM has more than one core, will each core have to be mapped?
6. "similar to the existing hook Shahar wrote" - can you please put a 
link the the hook that Shahar wrote. :) This will be helpful for those 
of us unfamiliar with it.
7. Why will live migration not be supported? What is the gap to have 
this type of support?

Thanks
Gary
