[libvirt] [PATCH v3 2/2] conf: List only online cpus for virsh emulatorpin

[Nitesh Konkar]

Currently when the vcpu placement is static
and cpuset is not specified, CPU Affinity
under virsh emulatorpin shows 0..CPUMAX. This
patchset will result in display of only
online CPU's under CPU Affinity on linux.
