This past Wenesday, there was a very interesting talk on VirtualIron at the
Boston Linux/Unix Group:
http://www.virtualiron.com/
And they do have a free download that will work on a single "socket"
system -- meaning, CPU socket, even if it is dual core. I am impressed with
their plans for the hardware vurtualization support in the very near future.
VI also supports drivers that are aware of the HyperVisor and sees
significant performance improvements as a result.
What I am interested in is whether or not VMWare has any advantages over
VirtualIron or vice versa. If I get the chance I'll make it up to MerriLUG,
but of late I've been run ragged with attending these SIG meetings. :-)

...
> Imagine this:

> You have a standard build of FC5, WinXP, Win server, solaris x86 ready
> to run just by copying 3 files.
>
> Who doesn't want a test sytem every now & then? Maybe 3 machines,
> each to test a different mail server?
>
> Or, you have several low CPU usage systems that are on thier own
> systems: license server, DNS/NIS, AD, DHCP, LDAP? Instead of 4
> systems using 10% cpu, you have 1 using 50% cpu.
>
> Even better, it's time to upgrade. Your servers are running in VMs.
> Get the new hardware, install your hostOS and then vmware server.
> Copy your 3 files for each VM to the new system, shut down the old,
> and start the new. Your VM's network, video, etc drivers are the
> same. No so important w/ Linux, but lesser OSes save lots of time.
> Just the host needs updating for the new hardware.
>
> Imagine a cluster of the above. All the files on a SAN. Move 'em
> off the dying hardware to the new via the SAN. Repair the hardware
> then move 'em back.
