I'm using unionfs-fuse with its example boot script to nfs-root boot
any number of hosts from a single disk based system. As such some of
the systems booted that way may need qemu because they don't support
kvm while others should use kvm because they can.
The single server would need to have both qemu and kvm installed
and decide at boot time which to use based on cpu capabilities.
So there is your production use case that needs both installed. It's
not just for short term testing.

PS: Given one installed Debian unionfs-fuse lets you configure and
boot a 1000 node cluster in 5 minutes.
/usr/share/doc/unionfs-fuse/examples/unionfs-fuse-nfs-root realy is
the best.
