On a remote network I run VM-Window7 a program (that uses mainly MySQL database). This program can be access only via Window7 or higher so any user who wants to have an access to that database has to run some Windows7 or higher. The main server that runs that program will be 8-core AMD with 16GB of RAM But I want to give an access to another user to that Windiws7 program, and I don't have a dedicated machine running Windows I run Windows via VM only. I have a small box Atom 2GB RAM 500GB SSD (running mainly asterisk, hylafax) but it will not run Windows7 not enough RAM, CPU-power etc. It will run Windows7 but painfully slow. When you star Windows7 on it you can go and have a coffee :-/ System uname: Linux-3.14.14-gentoo-x86_64-Intel-R-_Atom-TM-_CPU_330_@_1.60GHz-with-gentoo-2.3 (I'm in the process of upgrading it). So, instead of getting into trouble of making disk-less node I figure it out my Atom (small box) can access Main server via X2GO. I tested it on my local network and speed wise it works OK. Buy my computer is much faster than the Atom. So after upgrade I'll see how it will run. All boxes have gigabit network cards. So the user that runs small Atom box will access the main server via X2GO and start another VM-Wndows7 on it. My main sever can handle running two Windows7 via VM. I think this is best solution for now. -- Thelma
