Virutal private servers?

Virutal private servers?

[David Jackson]

Good day --
While looking for a dediciated server provider, I can across listings for
"virtual private servers"? What are they, how does one setup one up?

And is their any why to tell wheather they "dedicated server" your paying
for is really a virtual private server? Some of the dedicated pricing is
just to good??

TIA,
David Jackson

Hello:
  I estimate that they are using VMware GSX Server (www.vmware.com)
which creates complete virtual computers where you can install any OS
you want on it. For instance I use VMware Workstation and have Linux in
the real computer and have three virtual computers one with WinNT, other
with Win98 and the other with Win2000. I also tested a VM with Linux.
You will need plenty of RAM and hard disk, but it really works great.

Now that's an  interesting solutions.
I assumed that it was some form of chroot jail?
But your solutions would save on floor space, network, power
connections. You could even get something like a Sun E450 and
run virtual Linux in it.

Thanks for your comments.

though vmware is surprisingly efficient, the overhead is still pretty 
heavy. there are some cases where its the only way to have more than one 
user per physical server, but i would never even consider using it for 
anything that can be done by traditional means.
