VMWare is not free software.

linux-vserver is also free software and openvz is also free software (or
open source, if you prefer that name). And both make more sense in that
scenario: they basically give you a glorified chroot with the ability to
assign IP addresses to the instances. This is the level of separation
oyu're really after. You can easily share disks accross installations
(e.g: bind-mount in the host) and it is much easier to manage everything
from the host.

You can still share memory between instances.
