Advantage in running a virtual machine
Virtural box is new to me.
Its idea is not new to me. I'm also aware of Vmware but never testing it.
In my old days when I was running RH/Mandrake, etc. there were few applications running on Linux. Therefore I have to run "wine" installing Windows application on Linux box to keep me alive. Nowadays we have tons of application available on Open Source for Linux/Unix. Some of them you can't even find equivalent on Windows World.
I can't resolve what will be the purpose running several OS on the same PC (I don't run Windows). Even if I can build servers running on different OS on the same PC. What will be its advantage? The CPU resource has to be shared resulting in slowing down the speed of each server.
Please shed me somelight. Yours advice would be appreciated. TIA
