Running Windows Apps Under Linux, Part 2: Advice on installing and configuring four useful emulators

The other is bridged networking, in which
your virtual machines are actually on the same ethernet as your host.
You can use DHCP to allocate addresses for your virtual machines in
either case.

Once you have installed and configured VMware, you can create a virtual
machine and have it up and running within a few minutes after the
install with VMware's configuration wizard. The wizard takes you
through the steps of allocating space for the virtual machine's disk,
which can be a partition or a large file in your Linux file system. The
wizard also allows you to attach serial and parallel ports to the
appropriate devices under Linux, so your virtual machine has the full
complement of devices it needs.

However, once your virtual machine is up and running, you then have to
install an operating system on it! That is just like installing an
operating system on real hardware. As long as your virtual machine has
access to a CD-ROM, simply place the install CD into your system's CD-
ROM and power up your virtual machine (that is, click on the power
button). Your virtual machine will run through the installation process
and reboot at the end, just as Windows normally does.

In addition, VMware comes with a set of tools for each operating system
that it supports. Those tools allow your virtual machine to gain high-
speed access to the full display on your system instead of running in a
window.

Because VMware provides a virtual machine, it is not restricted to
running Windows. You can run quite a large number of operating systems
under VMware, including MS-DOS, Windows 9x, Windows NT, Windows 2000,
FreeBSD, and Linux. Thus, VMware is ideal for testing out new operating
systems, providing a teaching environment, or grabbing screen shots of
installation.

I also found the number of ways you can use VMware to be astounding.
The Samba team uses it to test out changes to Samba by simply running
Win NT in a virtual machine. I have used it to develop courses that
deal with the installation of operating systems, including the booting
phases, because I can very easily grab screen shots without the need
for a digital camera. Also, if you run those virtual machines out of a
virtual disk (a file in your file system) instead of a partition, it is
very easy to copy your virtual machine to another system or keep
backups.

The current version of VMware is 2.0.2, and it runs on all versions of
Linux, including SMP systems, and on Windows NT and Windows 2000. It is
priced at USD299 for commercial use and USD99 for hobbyist and student
use. You can download it from the VMware Website (see Resources for a
link). However, one of the things you will notice with VMware is that
it requires more resources than Wine or Win4Lin. For example, a VMware
virtual machine running on a 400 MHz Pentium II will feel like a real
machine running at around 200 MHz to 266 MHz.
