Put simply, is there a way to constrain a VM with 1 vCPU to consume no more than 0.5 of a physical core (hyper-threaded) on the server hardware mentioned below? Does the cap help in that respect?

You can use "cap" to make the VM in question get 50% of logical vcpu time,

This should be "logical CPU time"...
