This change requires you to run the bundled pre-install script, that will a
new group 'kvm' with proper permissions for the /dev/kvm device, to allow
unprivileged users (members of the kvm group) to run kvm-accelerated qemu
instances.
Please note that this change prevents non-root and non-kvm members from using
/dev/kvm acceleration.
qemu is now split into qemu with support for the x86 platform (both 32 and 64
bit and system and user emulation) and a qemu-all port that includes support
for all available platforms.
This was done to reduce build-time for the average user that will only use the
x86 emulation.
Please note, that both ports will kept in sync with regard to options and
versions and thus should be installed in a mutually exclusive fashion.
