comment Running Ubuntu in VirtualBox under Windows 8.1 doesn't use CPU on 100%
But the question still holds: can I (and if yes, how) reach that the guest OS can use all of my CPU power?

2.) Yes, I know that the guest Linux sees 2 cores with only one thread on each (as the lscpu in the question states) - so no hyperthreading. But I can't set CPU number to 4: i.imgur.com/RymrM7V.png, and as the documentation (virtualbox.org/manual/ch03.html#settings-processor) says: "You should not configure virtual machines to use more CPU cores than you have available physically (real cores, no hyperthreads)."

1.) Yes, I understand what HT is. But actually, task manager shows all 4 (virtual) cores at 100% if I do something CPU intensive on host side while the virtual machine running at full power: i.imgur.com/dWDfePg.png This means that the guest doesn't use full power of the CPU (because I can do other things host-side while guest is on 100% which increases CPU load).

OK, but I can do other heavy tasks on the host system while my guest uses the CPU on 100%, which increase the CPU usage on the host system, but doesn't decrease on the guest system. So it seems there are still power in my CPU which I can't use on the guest system.

I think it's the Execution Cap setting you mentioned, but (as I mentioned in the question) it's already set to 100% (my settings: i.imgur.com/RymrM7V.png; sorry, it's in Hungarian, similar English screen here: i.stack.imgur.com/UkRK5.jpg). And yes, from Windows I can use the CPU on 100%: i.imgur.com/dWDfePg.png
