[one-users] Setting CPU overcommit globally

Hi all,

In our environment, we need to overcommit the CPU in every host.

We have 6 host running KVM, on Ubuntu 12.04

Our Opennebula is 3.8.1

Previous discussion about CPU overcommit is suggesting that I have to put
CPU=0.5 and VCPU=2 to get 1 real CPU overcommit as 2 CPU, to each VM

Is there any way that I can just set it once, and when I launch/relaunch a
VM, it will be automatically CPU overcommit, without having to change the
VM template?
