Virtual Box - How can I increase CPU Utilization on multi-core processor

[Santiago3347]

I have an i7 - 4790 that I'm using for security research including pen testing. I require VBox to use more CPU resources. Currently I have everything setup the recommended way and have enabled PAE/NX as well as VT-x. BIOS has been setup for Intel Virtualization as well and this issue appears to specifically impact Oracles VBox. No Matter how many cores I select and having it set to 100% utilization I see the processor cycling the load between all the cores of the processor but never using more then 1 at a time. This dramatically increases time to run some of my tests and lab results vs doing the same test in a non-virtualized environment. I have looked through all the information I can find online to no-avail on how to resolve this issue. Any assistance is appreciated. With Vbox set to use 100% of the resources I have allocated I only hit 14% of my total CPU capability. Thanks for any assistance!

Change your pen testing program to use more than 1 thread. There's nothing that VirtualBox can do. Try to rip a DVD with Handbrake in your guest. Does the CPU gets used? Yes it will. Because Handbrake works with multiple CPUs, I don't know what your program does...
