Installing Kali Linux as a Virtual Machine in Virtual Box

[VicBollen]

Covered in this tutorial:
To change the amount of processors, select the System option and the Processor tab. As a default, the machine is granted only 1 VCPU. You can provide the VM as many processors as you like, but at least 2 are recommended.

Thanks for the great tutorial.

I got the following error when I tried to start up the VM in order to install the ISO:

Failed to open a session for the virtual machine kali

VT-x features locked or unavailable in MSR.
(VERR_VMX_MSR_LOCKED_OR_DISABLED)

I found a couple of sites that referenced this error:

But none of the solutions resolved my issue. What I ended up doing was reducing the number of processors back down to 1 and I was able to start up the VM and Kali install.

I had that issue as well with a very old laptop, no matter what I tried I couldn't get it to work. I enabled the bios and such, but it was a hardware issue I couldn't overcome.

I was trying to install it on a i7 laptop but I was using VirtualBox 4.1. It was only after I ran into problems with guest editions that I upgraded. But even though it works, Kali seems a lot slower than its predecessors. Maybe I'll try reinstalling Kali on the 4.2 version, see if I can bump up the VCPUs then.

My pentest VM has 4 vCPUs and 8192MB RAM, my standard is 2 vCPUs and 4096MB RAM. (Both 64 bit)

If that helps you at all, the first one is ofcourse super fast. Second one is good, but not as fast as the first

Thanks,
