Platform virtualization software, specifically emulators and hypervisors, are software packages that emulate the whole physical computer machine, often providing multiple virtual machines on one physical platform.
The table below compares basic information about platform virtualization hypervisors.
This table is meant to outline restrictions in the software dictated by licensing or capabilities.
Note: No limit means no enforced limit.
For example, a VM with 1 TB of memory cannot fit in a host with only 8 GB memory and no memory swap disk, so it will have a limit of 8 GB physically.
