VMware have some rather nice "lab" software that lets you recreate
groups of virtual machines instantly.  I think it's designed for
creating repeatable test environments.  The name of this escapes me
(and internet searches) right now, but I've often thought we could do
with something similarly easy to use.

Another thing to look at would be the various orchestration tools,
such as The Foreman, Heat and others.

I don't know if they can be used with KVM standalone however.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
