kvm: kvm-enabling wrapper for qemu-system-x86_64

NAME

kvm - kvm-enabling wrapper for qemu-system-x86_64

DESCRIPTION

The kvm wrapper script is used to provide compatibility with old qemu-kvm package which has been merged into qemu as of version 1.3.

The script executes

qemu-system-x86_64 -enable-kvm

passing all other command-line arguments to the qemu binary. This is not the same as old kvm binary, which was using less strict construct, similar to

qemu-system-x86_64 -machine accel=kvm:tcg

New wrapper ensures that kvm mode is enabled, or the VM will not start, while old code falled back to emulation (tcg) mode if kvm isn't available.
