You cannot simultaneously run two hypervisors on the same host OS, although you can install more than one.

Question

Quizplus · Accepted Answer

A hypervisor is a software layer that allows multiple operating systems to run on a single physical server. Each operating system runs in its own virtual machine (VM), which is isolated from the other VMs. Only one hypervisor can be running on a single host OS at a time, because the hypervisor controls the hardware resources of the host OS.
