+# Pick up modified default configuration for virtual machines
+# that disables jitter entropy source, as it is not useful when
+# the VMs are effectively driven by the host RNG via virtio-rng.
+# This also helps boot speed, as otherwise the guests have rngd
+# potentially somewhat pointlessly burning a lot of CPU on boot,
+# in addition to the host's own rngd.
