Online game server and virtualization

Hello,
I have an Acer Aspire M3100. Recently I wanted a little fun with the pc, trying to create an online game server for my home network. I installed Virtual PC by Microsoft, except that it refuses to start because, it tells me that virtualization is not enabled in the BIOS settings.
Well, I restarted my computer, accesses the BIOS settings, then those of the CPU. Except that the option for Virtualization is nowhere…
Do you have any ideas?
Thank you.
