-# Hardware RNG into a Ganeti Instance
-
-On ganeti node:
-
-    gnt-instance modify -H kvm_extra="-device virtio-rng" foo.rg.net
-
-You'll need to activate the change by restarting the hypervisor from
-ganeti cli: gnt-instance stop foo && gnt-instance start foo
-
-Inside foo.rg.net:
-
-    apt install rng-tools
-
-That creates /dev/hwrng which is the KVM pass-thru for virtio-rng.
-
-    systemctl status rng-tools.service
-
-     rng-tools.service - Add entropy to /dev/random 's pool a hardware RNG

-
-Note the last line that shows rng-tools found /dev/hwrng.
-
-N.B.: I haven't run rngtest or done any other test atm to check the
-randomness, but it seems to work.
-
-If you want to do this for all guests, you can do 'gnt-cluster modify'
-instead and set kvm_extra there.
-
-    gnt-cluster modify -H kvm:kvm_extra="-device virtio-rng"
-
-I just wanted to demo how to do this for a single guest.
-
-tada!
