KVM - Pin a CPU

See Get the CPU Pinning Settings for a Guest

Pinning is a way to limit the effect a certain guest has on others, or to give a guest a dedicated core etc.

To set the cores that a guest can use.

virsh vcpupin VM_ID 0 2

NOTE: This will set the first vCPU (the one with ID 0) to only run on core ID 2.

Thus the output of **virsh vcpupin VM_ID would report:

VCPU: CPU Affinity

 0: 2
 1: 0-3
