"Two years ago, we visited the subject of free desktop
virtualization hypervisors. At the time, the two preferred free
solutions were Sun's xVM VirtualBox and and VMWare Server 2.0.
"Things have changed quite a bit in the last two years. For
starters, Sun no longer exists as an independent company —
it's now owned by Oracle.
"VMWare, a division of EMC Corporation, decided to make some
strategic changes along the lines of its free virtualization
solutions by offering its enterprise-level hypervisor, ESX Server,
in a free version, ESXi. This complicates things somewhat for the
desktop virtualization user seeking a free solution, as ESX 3i
requires a dedicated system.
"While the company continues to maintain VMWare Server 2.0, its
free hosted virtualization product, it has concentrated its desktop
virtualization development efforts on VMWare Workstation, a $189.00
desktop virtualization software package."
