All,Attached is the patch over qemu-2.4.1. I have tested this on Centos7.1 with CentOS VMs using KVM. I am not sure how it effects other platforms.
It adds a new parameter "-vcpu" to command line. The usage example is " -vcpu 0,affinity=20" (pin VCPU 0 to CPU ID 20). Please see if it helps you.regards,RaviOn Thu, Jan 21, 2016 at 3:56 PM, alex3kov <address@hidden> wrote:I'm interested in that as well. Would you mind proposing your patch upstream?---- On Thu, 21 Jan 2016 13:09:28 +0400 Bhattiprolu RaviKumar <address@hidden>wrote ----Varun,I also have a similar requirement. I had patched the code over qemu 2.4.1 to add extra options to pin a VCPU to a physical CPU. I am not sure why this option is not there in qemu. (or I am not aware). If you use the taskset all the VCPU threads are getting same mask.If you are interested, I can post the patch above qemu 2.4.1regards,Ravi
