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, Ravi On Thu, Jan 21, 2016 at 3:56 PM, alex3kov <alex3...@zoho.com> wrote: > I'm interested in that as well.
