Offhand, I don't, but there's probably a tool for doing it. And you can
always do it from "inside" the virtualized environment, where the OS
sees that storage as a real, physical disk. If it's the boot drive,
imaging it wouldn't be advisable, but if the drive can be unmounted,
then simply copying it at the physical level would suffice.
I should point that this capability exists in VMware Workstation. I
don't know if it's in the free Server product (it lacks many of the
features of Workstation), so you should check that, too. VMware
Workstation isn't exactly inexpensive.

could virtual machine software make use of a separate harddisk
instead of a disk image to improve its performance?
VMware supports it. I use it for my Windows XP. In fact, Windows XP
sees a whole drive in what is actually a single partition of one of
my physical drives. It's bit odd, but it works fine.
What is the name / terminology used for this? If you give me the
right keyword I should be able to google out everything.

By the way do you know if I can convert an existing hard-disk image
file to a real harddisk?
