KVM Installation – Fixing KVM Not Installed on This Machine (/dev/kvm Missing)

See the instructions here: https://help.ubuntu.com/community/KVM/Installation

In short:

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils
sudo adduser `id -un` libvirtd
sudo adduser `id -un` kvm

Then log out and back in again, and check that it is working by running:

virsh -c qemu:///system list

Some more instructions from Intel: https://software.intel.com/en-us/blogs/2012/03/12/how-to-start-intel-hardware-assisted-virtualization-hypervisor-on-linux-to-speed-up-intel-android-x86-emulator

The error you get when you try the command kvm-ok gives you two other commands which may resolve your problem :

1. sudo modprobe kvm-intel(with intel CPU, replace, with -amd for AMD ones) or sudo modprobe kvm : this will load the kvm virtualisation module into the kernel, allowing VM to run properly.

2. running sudo /usr/sbin/kvm-ok : will run it as root.

The first one is the most likely to work, so try it first, and then run the second one.

EDIT :

I just noticed in your answer that you said your BIOS supported it, but not that it was enabled... It's probably just a misunderstanding from me, but check anyway...
