Currently we only allow /dev/random and /dev/hwrng as host input
for <rng><backend model='random'/> device. This was added after
various upstream discussions in commit 4932ef45
However this restriction has generated quite a few complaints over
the years, so a new discussion was initiated:
http://www.redhat.com/archives/libvir-list/2016-April/msg00987.html
Several people suggested removing the restriction, and nobody really
spoke up to defend it. So this patch drops the path restriction
entirely

This backend type expects a non-blocking character device as input.
- The only accepted paths are /dev/random and /dev/hwrng. The file
- name is specified as contents of the <code>backend</code>
element.
- When no file name is specified the hypervisor default is used.

I'd rather keep the "hypervisor default" wording. /dev/urandom is in no
way platform or hypervisor agnostic. You may add though that for qemu
driver the default indeed is /dev/random.
