> Add KVM support to QEMU
>
> This patch adds very basic KVM support.  KVM is a kernel module for Linux that
> allows userspace programs to make use of hardware virtualization support.  It
> current supports x86 hardware virtualization using Intel VT-x or AMD-V.  It
> also supports IA64 VT-i, PPC 440, and S390.
>
> This patch only implements the bare minimum support to get a guest booting.  It
> has very little impact the rest of QEMU and attempts to integrate nicely with
> the rest of QEMU.
>
> Even though this implementation is basic, it is significantly faster than TCG.
> Booting and shutting down a Linux guest:
>
> w/TCG:  1:32.36 elapsed  84% CPU
>
> w/KVM:  0:31.14 elapsed  59% CPU
>
> Right now, KVM is disabled by default and must be explicitly enabled with
>  -enable-kvm.  We can enable it by default later when we have had better
> testing.

The source seems to be missing, probably forgotten?

Cheers
