Thanks for your quick answer.

I took at look at that documentation, but I did not quite understand it. It talks about vCPUs and how they are scheduled. My guess is that it is all 
about how those virtual CPUs are scheduled against each other.

However, I wanted to lower the priority of all virtual machines against other processes on the host system.
