What's an ATMEGA8? Looks like a 168 on the virtual Protoboard, is that what you meant?
A few more discrete parts are required for an ATmega8 chip to run, and be programmable. Tutorial

No decoupling caps?
No crystal (or associated caps)?
No pullup on target /RESET?
(Possibly) No 10uF on programmer /RESET?
