Description Roy Golan 2013-12-02 15:17:04 UTC 
oVirt engine should support dynamically add/remove virtual CPUs to/from a guest that has this capability

WIKI: www.ovirt.org/Hot_plug_cpu

UI:
admin can now edit a running VM number of CPU. when confirming the 'edit VM' dialog it will add/remove vcpus and online them, if the underling OS supports that

REST:
use PUT ovirt-engine/api/vms/{id} to update the number of sockets and online them if the number changed

Comment 4 Michal Skrivanek 2014-02-06 10:42:45 UTC 
allocation is in, deallocation is not. Missing guest agent support and actual reporting of the real stasus as seen by guest. And deallocation which is not really supported in QEMU yet (only offlining is)

We may open a follow up bugs for the issues above
Comment 5 Itamar Heim 2014-02-25 13:14:20 UTC 
maybe change scope of this RFE to allocation and move to ON_QA?
Comment 6 Michal Skrivanek 2014-03-24 09:05:12 UTC 
removing unplug addressed by bug 1077515
