How to throttle a VMs host CPU utilization in VMware

Hi,  I am tight on hosts right now as I await hardware to arrive for a downed host.  But I am needing to spin up a new VM for some colleagues.  I have a host that has more than enough resources, but it has some important VMs already on it.  And because of the nature of what this new VM will be doing, it tends to try to use all of the host CPU resources available to it.  

I know there is a way to instruct VMware at the VM level to force the VM to never use more than some percentage of the hosts CPU resources.  

What is the best way to configure this VM to never use more than 50% of the the host's entire CPU resources?  And procedural, how do I configure this?  IE where are these settings located?

Thanks a lot :-)

Simple answer is, IF your host has 12 virtual cpu's then give your VM only 6!
If it has 2 then give it only 1!

Alternatively create a resource pool

if you want to give your VM less, than 2000GHz processor, you can experiment with Shares, or Resources and limit the number of MHz or cycles!

or Create a Resource Pool with limited resources, or RESERVE resources for current VMs, which will guarantee that they always get CPU and MEMORY resources.

but if you give your VM, 1 vCPU, it will not be able to use more than 1 vCPU!

Ok, thanks for the info, I will for now limit this VM to two VCPU's.  Since this is only temporary, I am not going to go through the bother of setting up resource pools and shares.  Though I will investigate it further when I have time and a few spare non critical hosts to test on.
