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.   ~Peeyush Gupta ________________________________ From: Saurabh Deochake <saurabh.d04@gmail.com> To: Peeyush Gupta <gpeeyush@ymail.com> Cc: "libvirt-users@redhat.com" <libvirt-users@redhat.com> Sent: Saturday, 27 July 2013 2:13 PM 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?

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.  ~Peeyush Gupta _______________________________________________ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
