====== KVM - Pin a CPU ======

See [[KVM:Get the CPU Pinning Settings for a Guest|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.

<code bash>
virsh vcpupin VM_ID 0 2
</code>

<WRAP info>
**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
