Ghost or Virtualisation ?

Hi Guys,

I always heard that datacenters are using Virtualization. Much better
for maintenance...
-> OK, that's right... you can save a copy of your virtual iage...
Now, virtualization, seems to be really memory gready. Apparently, a
server running 2 Gb of RAM, need to be upgraded to 4 Gb ( I am playing
at the moment with VirtualBox )

Now, I can see that there is a g4l ( Ghost for Linux )
I didn't play with it yet, but I found ghost for Windows machines,
really easy to use.....

- Don't you think that that could be a better solution ?
Not 2 layers, but just one layer of software ?? -> quicker .....

- Why dataceters seems to be more focus on virtualisation ?

- Did I miss something ??

Much better for hardware utilization.

More bang for their hardware buck. A virtualized RHEL5.2 Linux host may
have a Microsoft Windows server as a "guest" OS, or even have Fedora as
a guest OS.

Probably. Try Googling Virtualization. g4l & Ghost don't closely
relate to virtualization in the context you are using.
