17. Displaying Virtual CPU Information

You can use virsh to display virtual CPU information from a virtual machine:

virsh vcpuinfo [domain-id | domain-name | domain-uuid]

18. Configuring Virtual CPU Affinity

You can use virsh to configure the affinity of virtuals CPUs with physical CPUs:

virsh vcpupin [domain-id | domain-name | domain-uuid] [vcpu] , [cpulist]

Where [vcpu] is the virtual VCPU number and [cpulist] lists the physical number of CPUs.

19. Configuring Virtual CPU Count

You can use virsh to modify a Virtual Machine's number of CPUs:

virsh setvcpus [domain-name | domain-id | domain-uuid] [count]
