14.13.3. Configuring Virtual CPU Affinity
To configure the affinity of virtual CPUs with physical CPUs, refer to Example 14.3, “Pinning vCPU to a host physical machine's CPU”.
Example 14.3. Pinning vCPU to a host physical machine's CPU
The
virsh vcpupin assigns a virtual CPU to a physical one.
# virsh vcpupin rhel6 VCPU: CPU Affinity ---------------------------------- 0: 0-3 1: 0-3
The
vcpupin can take the following options:
--vcpurequires the vcpu number[--cpulist] >string<lists the host physical machine's CPU number(s) to set, or omit an optional query--configaffects next boot--liveaffects the running domain--currentaffects the current domain
