Rob Bradford e70bd069b3 vmm: Load kernel asynchronously
Start loading the kernel as possible in the VM in a separate thread.
Whilst it is loading other work can be carried out such as initialising
the devices.

The biggest performance improvement is seen with a more complex set of
devices. If using e.g. four virtio-net devices then the time to start the
kernel improves by 20-30ms. With the simplest configuration the
improvement was of the order of 2-3ms.
