When talking about using a block device for hard disk image for virtual
machine, Boyd said:

However, this may or may not actually increase your performance, depending
on the virtualization software. If they use the same techniques as the
kernel uses for swap files, the performance increase is tremendously
minimal.
do people know a virtual machine software that can improve performance
by making use of a separate harddisk instead of a disk image?

Sorry for posting similar questions twice, but last thread went to the
discussion of "can a virtual machine use harddisk as harddisk image" even since
the very first follow-up posts so I think restart another thread with clearer
question helps.

Thank you all for who replied my last question.
