Today's other accomplishment was spending long enough looking at
Toshiba ACPI dumps to figure out how to enable hotkey reporting
without needing to poll. Of course, I then found that the FreeBSD
driver has done the same thing since 2004. Never mind.

The real difference between KVM and Xen is that Xen is a separate Operating
System dedicated to virtualization. In many ways, it's a fork of Linux
since it uses quite a lot of Linux code.
The argument for Xen as a separate OS is no different than the argument for
a dedicated Real Time Operating System, a dedicated OS for embedded
systems, or a dedicated OS for a very large system.
Having the distros ship Xen was a really odd thing from a Linux
perspective. It's as if Red Hat started shipping VXworks with a Linux
emulation layer as Real Time Linux.

You say, "You never know when your MB, CPU, PS" may bite the
dust. Sure, but you also never know when your RAID controller will
bite the dust and start writing data blocks whenever it's supposed
to be reading from the RAID (yes, we had an Octel voice mailbox
server fail in just that way at MIT once). And you never know when
a hard drive will fail. So if you have those sorts of very high
levels of reliability requirements, then you will probably be
disappointed with any commodity hardware solution. I can direct you
to an IBM salesperson who will be very happy to sell you an IBM
to post comments)
