And without even getting into closed/proprietary guests, virt is useful
for testing/developing/deploying many free OSes, eg FreeBSD, NetBSD,
OpenBSD, Hurd, <random research OS>, etc.  Not to mention just wanting a
stable [virtual] platform to run <old enterprise Linux distro> on.  So
having a virtual platform whose interface doesn't change very often or
very much has a lot of value at least in avoiding churn in guest OSes.
