I'd like to start using vmware vsphere and esxi more for my performance lab. In order to do that if I create a virtual machine with X vcpu and Xgb ram. I would need to know that it is in fact only using something like 2 of the 2.7ghz cores.
For instance if I have a server with 2x6 3.0ghz processers running esxi 5 and create 1 vm on it and I want it to use 4x3.0ghz cores at all times, how can I go about enforcing that? Later on I might add other VM's but they will all essentially have to have the same style guarantee of resources so that we can use it for sizing, etc.
