14.13.5. Configuring Virtual CPU Affinity
To configure the affinity of virtual CPUs with physical CPUs:
virsh vcpupin domain-id vcpu cpulist
# virsh vcpupin domain-id vcpu cpulist
The
domain-id parameter is the guest virtual machine's ID number or name.
The
vcpu parameter denotes the number of virtualized CPUs allocated to the guest virtual machine.The vcpu parameter must be provided.
The
cpulist parameter is a list of physical CPU identifier numbers separated by commas. The cpulist parameter determines which physical CPUs the VCPUs can run on.
Additional parameters such as
--config affect the next boot, whereas --live affects the running domain, and --current affects the current domain.
