The genericcloud image differs from the generic image only in that it
installs the cloud kernel, rather than the standard Debian kernel. The
cloud kernel leaves out most device drivers, and primarily targets the
Amazon EC2 and Microsoft Azure VM device models. Functionality outside
of those environments is not guaranteed.
We need to better document this...

qemu-guest-agent assumes a level of integration between the VM and the
underlying infrastructure that is not appropriate for a general purpose
image. Our published images need to be suitable for use in environments
where there's a trust boundary between the VM and the underlying host.
