ESX does _not_ run on top of Linux! The current 3.x product use a customized
version of Red Hed Enterprise Linux as a special VM that runs on the VMkernel
(=hypervisor). ESXi 3.5 does not need this special VM anymore. ESX 4 and
above will not have it in any edition.

I thought Hyper-V was part of Server 2008. I know ESX runs on top of Linux.
Perhaps my definition of "hardware-based virtualization" is different. The
Unisys ES7000 is one platform which I consider "hardware-based
virtualization". The Egenera BladeFrames and Blades are another. The prior
uses Server Sentinal (IIRC) to manage the hardware, and the latter PAN
Manager and vBlade Software. Once the virtual hardware boxes are configured,
though, my understanding is that the passing of architecture is more like
that which you get from a BIOS rather than software that sits on a OS stack
to which API calls are made - if that makes any sense; there's no 'host' OS
in the equation.
I had thought Hyper-V was hosted on Server 2008 and I know ESX is hosted on
Linux. I guess, I've never considered any kind of 'OS host'-based
virtualization as 'hardware-based' virtualization.

As of SP1, Virtual Server R2 adds "hardware-assisted" virtualization.
AFAIK, the only VMWare product that dies this is ESX...

Which are you implying is hardware-based virtualization? Or were you
just "saying"? :)
Egenera looks pretty good for hardware-based virtualization, though.
The client I'm working at currently will probably be setting up a couple of
chassis sometime in the near future. Should be interesting.

SCVMM is intended to be the management tool of choice; that's
why they're building it.
RC1 should hit the streets soon; it'll be well worth the time
to grab & install it.

I was most unimpressed by the hyperv management console. The
system center/virtual machine manager was the only way I would ever use it,
but you need to be using multiple servers to warrant that, but given that the
vmm was built on powershell it would be a good thing to drive from the cli if
you are so inclined. That and running (read) managing HV on SC was near
impossible unless you had rsat or another hyperv machine you could connect to
the console (which wasn't available at the time). You were supposed to be
able to use wmi to drive it but I was told that MS hadn't finished the docco
on that. It might be great when they finish it.
Vmware beta2 has some nice things about it and you can use the
ESX client to manage it. Having used ESX and Virtual Iron in production I
would say they have a way to go but I'm keen to setup an environment at work.
We have 60 or so standalone vm boxes that dev and qa use and we are looking
at using something to consolidate them, hyperv seems like it will fit the
bill there.

Got my ISA 2006 server running on Hyper-V now.
I'll soon migrate to TMG (probably not today; gardening
awaits).
