Perhaps for some of our workloads LXC and LXD (for 'live migration' 
things) would work, but I have a need on a few VM's to have different 
kernels and even completely different yet paravirtualized OSes (pfSense 
for one, since FreeBSD has paravirtualization drivers) running, even 
going as far as having mixed 32 and 64 bit installs. Some of the 
applications we use are a bit version-locked for various reasons beyond 
our control.  And, yes, I'd like hypervisor-based HA and live migration 
for my pfSense and OpenBSD VM's.
