"In Late February, VMWare announced the release of ESX Server
3i, the first release of their embedded hypervisor platform for
OEMs. Their initial list of partners who agreed to offer 3i

using 3i within the next week, in ten distinct models, and it is
expected that similar announcements from the other Tier 1 system
vendors will be made within the next few weeks.
"There are certainly a lot of reasons why you'd want hypervisors
to be embedded in firmware--obviously tying it closer to the
hardware platform gets you around a number of integration and
performance issues, and it makes sense for it to be more aligned
with the BIOS than the OS itself..."
