This week's TechRepublic poll ask which virtualization software is the
best: VMware, Virtual Server, or Xen. Starting Monday morning, you can
In my experience, VMware does the best job of hardware emulation. I've
run into the fewest installation problems when installing a variety of
operating systems into VMware virtual machines. However, using the
default settings in VMware, the virtual machines often drag in
performance. This can be enhanced with some tuning.
By contrast, Virtual PC (even before Microsoft bought it) has typically
caused me some installation problems, but once you have a virtual
machine up and running, it tends to perform a little better and is more
usable than VMware's default performance.
I've hasn't used Xen yet, but I've heard some good things about it, especially Virtual Iron.
I'd love to hear the experiences that other IT pros have had with these virtualization products.
