[one-users] cpu overcommit with kvm

[Carlos A.]

there was a bug about the CPU template parameter that was not working 
for vmware so it was needed to use VCPU instead. Thus, I have no way to 
manage the overcommitment of VMs to a host.

Is this issue solved in the current version? (i have noticed that memory 
issues are supposed to be (partially) patched)
