There is no valid use-case of rng-random other than using /dev/random. In fact, it was probably a mistake to even allow a filename to be specified because it lets people do silly things (like /dev/urandom).
If you want anything other than /dev/random, you should use rng-egd.
/dev/hwrng makes sense too.
Good point. Perhaps we should issue a warning when anything is used other than /dev/random or /dev/hwrng to discourage people from doing the wrong thing. I completely understand the confusion and I think we should try a bit harder to prevent people from getting it wrong.
Then libvirt should also make sure that the XML we allow for non-egd virtio-rng is restricted to the two filenames that won't cause a qemu warning, or even modify the XML to not expose a filename in the first place. We haven't released libvirt 1.0.3 yet, so we still have a few hours in which such a change could be made before the XML becomes baked by a release. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
