How can I install KVM on Ubuntu 12.04 when I have a VM

I have a Windows 8 machine. Now, I need to use KVM on Ubuntu 12.04 LTS. To avoid to make a disk partition, I have installed VirtualBox and run on it Ubuntu 12.04 LTS as Virtual Machine. Now, I want to install and configure KVM on it. I'm following this guide:

http://www.howtogeek.com/117635/how-to-install-kvm-and-create-virtual-machines-on-ubuntu/

but, when I execute this command:

egrep -c ‘(svm|vmx)’ /proc/cpuinfo

I get

0

I read that

"A 0 indicates that your CPU doesn’t support hardware virtualization"

I have seen "virtualbox setting" and I note that, in the "System" tab, I have marked the hardware virtualization options. Why I get this value when I run that command?

so you put a virtual environment inside a virtual environment on a windows machine. That doesn't make much sense.

You have already installed Ubuntu in Virtualbox, so it is not directly using the CPU (but the virtualized CPU provided by Virtualbox). egrep -c ‘(svm|vmx)’ /proc/cpuinfo won't give you the results of the host CPU now. check the first lines of this and you'll see what I mean: cat /proc/cpuinfo

To help diagnose one of the issues.. do not create a symbolic link. The VM guest must have virtualization enabled.

For e.g in VMWare, in the VM iamge settings... see the Hardware Processor settings has Virtualize Intel VT-x/EPT or AMD-V/RVI enabled

I get precisely the same results when running Ubuntu 14.04 LTS as guest Virtual Machine within Hyper-v on Windows 8.1.

I'm also very interested in hearing feedback. KVM shows as being installed in /usr/bin. However, Android Studio is looking for it in /dev. To trick it, I created a symbolic link in /dev pointing to /usr/bin/kvm. Running against this setup returns a similar message of:

Could not extract KVM version: Inappropriate ioctl for device
