Hi,
I have a basic doubt, while increasing vCPU for a VM in RHEV-M, do we need
to increase core or sockets? For instance, if someone asks for 2vCPU then
should i make it 2 socket x 1 core or 1 socket x 2 core..
I do understand that it depends on application too to choose. but i'm
asking in general.
Sorry, if its not relevant to this forum.
Thanks

AFAIK you need to increase sockets, not cores, at least
this is what ovirt does atm, and I think libvirt/qemu/kvm
do it the same way, but I'm not 100% sure.
See:
http://www.linux-kvm.org/page/CPUHotPlug
http://wiki.qemu.org/Features/CPUHotplug
But I'm also wondering if an additional socket is the
right way to go from a design perspective.
So I'd like to hear more opinions on this topic.

Its not clear if increase is while the VM is running, meaning hot plug cpu
