I am using Virtualbox to virtualise a Windows server on my Debian box. My computer neither has VT nor AMD Virtualization technology. When I look with top the virtualbox process never goes over 100% cpu usage. But I have 4 cores, so the maximum cpu usage would be 400%. Is there a possibility to increase the limit for the cpu usage of the Virtualbox process to over 100%?

This question came from our site for professional and enthusiast programmers.

Did you assign more than one virtual CPU to your Windows server guest? – Goyuix Sep 24 '12 at 14:35

" the maximum cpu usage would be 400%"

False. 100 = all the cores on max. If only one core would be used, the load would be 25%.
