The HOWTO shows how to create a virtual disk using the
qemu-img command from
qemu, how to add such a disk
image to simple the VMWare Player configuration file, and howto install into
that disk, and later boot from it, inside a VMWare Player session.
All of this should actually work for just about any bootable iso with an installer, not just those that are based on Knoppix. Feedback welcome!
