What is the delay it takes to execute memory and cpu between the hypervisor and vm?

[knoxvegas31]

I wanted to know the delay for execution of CPU and memory between the VM and Hypervisor. I know there is some kind of delay when the VM executes cpu or memory because it's passed off to the hypervisor and handed back to the VM. Thanks for the help.

It depends on workload and server utilization. If the system is not fully loaded and the active code is in user space there is zero delay. If the host is heavily utilized then the VM is provided a time slice of system resources and will have to wait its turn for access to the CPU. The delay in this case is dependent on system's load.

In short, delay to CPU and memory can be and often is zero.
