"...called VMotion that allows you to move a virtual machine from onephysical machine to another with no effect on connected users..."

And that is as cool as it gets - load balancing for a virtual machine.Does anyone know how cool it is that you can actually move a "Winserver" to another freakin' box without anybody having any clue thatyou've done it? Phillip was just showing me this stuff the other day andI'm totally blown away. I just thought VMWare was a cool way that Icould run Windows on my Mandrake box -- boy was I ever wrong. Thisstuff is nothing short of amazing.

I thought that originally but I've found there are strong reasons to run
servers in an virtual, isolated environment. My knowledge is mostly VMWare
but here are some reasons that I've come up with to use virtualization.

* Multiple virtual machines can share the same hardware with no
interference. This allows many small machines to be consolidated onto a few
large systems. VMWare also guarantees that each virtual machine is
completely isolated from each other so if one has a problem it doesn't
effect the others.

* If two pieces of software don't work well together or require different
versions of libraries that can't be installed on the same system could be
installed on two virtual systems.

* To back-up an entire running system is as simple as copying a folder.
Also, virtual machines can be cloned. I cloned a completely configured 10
gig installation of Windows XP for someone in about 5 minutes. The install
and configuration on the original took me over 2 hours.

* While a virtual machine is running you can take a "snapshot" where at some
point in the future you can revert the entire system to that snapshot. As an
example, before deploying ServicePack 2 on every system, create a virtual
machine and take a snapshot, then install the ServicePack and if there are
any issues which can't be solved simply revert to the snapshot and try
again. This saves the time of installing and configuring Windows before
trying the ServicePack.

* VMWare has a product called VMotion that allows you to move a virtual
machine from one physical machine to another with no effect on connected
users, that way if a physical server has too much load you can simply move
the virtual machines around to accommodate.

* For the administrator there is a web based user interface and a
stand-alone interface to connect to the physical servers, this gives a
graphical interface to administer all of the virtual systems.



I hope this provides some ideas where virtualization can be useful.
