hosted hypervisor
This Type 2 hypervisor (hosted) can then create ___ ___ ___(VMs) that will each run a guest operating system. In this case, guest operating systems do not need to be the same as the host OS.
multiple virtual machines
However, not all virtualized servers make use of a host operating system. In many cases, a ___ ___ ___, also known as a bare-metal hypervisor, is installed directly onto a server’s hardware.
Type 1 Hypervisor
The Type 1 hypervisor takes the place of the ___ ___ and can then create virtual machines, each of which may run a guest operating system.
