Added "kvm" Virtualization (With GPU Passthrough)

[Mohido]

Description

I needed a way to automate the KVM installation with "GPU Passthrough". Now, we can use the following bash command to install kvm (with gpu passthrough).

make install TAGS="kvm" EXTRA_VARS="kvm_enabled=true"

Notes

Running this command will make a GRUB menu shows during the bootloading phase. The menu will include which GPU you want to passthrough. By default, the normal ubuntu will bootup (after 20 seconds) with normal GPUs (gpu-passthrough disabled).
