[one-users] what's the exact meaning of CPU in vm template file?

[XIE Xin B]

Hello,
In one vm template file, we can define such as
CPU = 0.6
Definition is : Percentage of CPU divided by 100 required for the
Virtual Machine.	 

my question is what's the meaning of this? 1 or 2 or both?
1. if host's reamining cpu<60%, the vm will not dispatch on the host
2. after vm dispatched on the host, it will occupy 60% cpu at most, if
more than that, host will not allocate CPU to the vm
