Snapshot tools can quickly capture the content of that VM's memory space and save it to disk in moments. There are two types of hypervisors: Type 1, or "bare-metal" runs directly on the hardware, while Type 2 runs on a host operating system.  "Bare metal" hypervisors are the most common and popular type of hypervisor for the enterprise data center.
