Description Mark Goodwin 2017-01-03 04:36:46 UTC

Description of problem: pmdalinux should support CPU hotplug/unplug for KVM guests

Steps to Reproduce:
1. setup a qemu/kvm guest (RHEL6.5 or later) with 2 vCPUs and provisioned for 4 vCPUs
2. boot guest
3. use virt-manager to hotplug 2 more vCPUs

Actual results: guest pmdalinux CPU indom stays at 2 vCPUS

Expected results: guest pmdalinux CPU indom should be dynamic

Additional info: vCPU hot-unplug doesn't seem to be supported (not yet anyway on my sandybridge host running f25), but that should be accommodated too.
