[libvirt-users] pinVcpu not working

[Peeyush Gupta]

Hi Saurabh,

I checked that out and it's working. Looks like I wasn't able to understand how to define cpumap. Anyways, thanks for your answer.

Hi Peeyush,

If we want to pin vcpu1 of a domain to CPUs 3 and 4, we need to pass:

dom.pinVcpu(1, (False, False, False, True, True, False....[and so on, til number of logical CPUs of host]))

Can you please check this?
