I've used HyperV so far for virtualizing my clients' servers, but I want a solution for those that don't have licensing to install a 2008 R2 Server for HyperV. So I was thinking of using Linux to transfer their Servers from the hardware to a virtual environment. Unfortunately my Linux knowledge is almost none aside from using Ubuntu here and there.
From what I've seen the only real differences for Ubuntu Desktop and Server editions is that server has no GUI and different applications/services installed.
After researching for quite a bit I've found that Virtual Box is probably the best way to go, I was leaning towards Xen for a while but after a few posted test results it swayed me back to VirtualBox.
So here's what I was thinking of doing, I could install the Ubuntu Server with virtualization services checked off then drop in a core GUI like Gnome and run VirtualBox from within that and run their servers virtually. Is this a viable solution? Will it be reliable and run 32 and 64 bit servers? Etc.
Any info as always is greatly appreciated!
