"The standalone hypervisor is also interesting in that it will
offer users and unbundled version of KVM. Red Hat's vice president
of engineering, Brian Stevens, describes RHEV-H as a:
"Stateless hypervisor, with a tight footprint of under 128MB,
which presents a libvirt interface to the management tier.
Enterprise servers will no longer need to go through an
installation process, and will instead be able to boot RHEV-H from
flash or a network server, and be able to immediately begin
servicing virtual guests. This stateless model drives down OPEX and
enables the scalability required by terascale grids, large
datacenters and cloud class compute environments.
"The advantage of such an approach, says Stevens, is that as a
"bare metal" Linux hypervisor RHEV-H will benefit immediately from
the evolution of the Linux kernel and any device - "from the phone,
appliance, desktop to server which are increasingly powered by
Linux" - will have the ability to host virtualised machines."
