Hmm, could be. Due to the long time it'd be needed to run --all-tests, I 
thought it wouldn't be necessary.

One thing that does help here is to know that you can specify only the 
first component of the test name displayed on --help, and it'll run all 
derivated tests. For example, if you want to run all virtio_console 
tests, you can just specify:

./run -t kvm --qemu-bin=/path/to/qemu --tests virtio_console

virtio_console.spread_linear.specifiable.virtserialport.with_vm.open:

I need to think of a good way of exposing this information on help output...
