I am beginning to have very similar thoughts. It's working fine for me now, but at
some point something big is going to break. I already have VMWare running, and in fact,
my two ESXi nodes have the exact same hardware as my two KVM nodes. Would be simple to
do, but I really don't want to go just yet. At the same time, I don't want to be
the last person turning off the lights. Difficult times.
