Improved error message is good, but it is better if the mgmt apps knows
not to try this in the first place.

IOW, I think we want "query-machines" to filter out machines
which are not available with the currently configured accelerator.

libvirt will probe separately with both TCG and KVM enabled, so if
query-machines can give the right answer in these cases, libvirt
will probably "just work" and not offer to even start such a VM.
