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.

Subject: Re: [libvirt-users] pinVcpu not working

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?

Hi all,

I am working with libvirt and I am trying to set cpu affinity. Now I can always use 

    virsh vcpupin <domain_name> <vcpu> <pcpu>

to pin vcpus to pcpus. I want to do it using Python API. Now, there is function pinVcpu which is supposed to do that. But this is not working. For example I gave 

    dom.pinVcpu(0,1)

but still my vcpu affinity is for all the pcpus. The function returns 0 (success).
Any idea what am I doing wrong?

Thanks.
