The i3-2130 that you have is a 3.4 GHz dual core chip that supports VT-x, it's designed for virtualization.
The 119 euro plan that DSL_Ricer got his dad, that's a 1.8 GHz Atom D425. Single core, no VT-x support (or any other virtualization extensions), and the Atom is pretty damned slow clock-for-clock. It's great for light web serving and VPN use, but it's really not a good chip for virtualization.
EDIT: Also, vSphere's minimum requirements suggest a single-chip-dual-core or dual-chip-single-core server, which the Atom isn't.--
