From admin's view, LB+VM mode is charming, it's more secu, easily to
test, deploy, backup and destroy. I didn't care XEN or Bhyve, it's too
heavy, but ezjail+Vimage+rtld is amazing and lacks on isolate.

Running well in virtualized environments is important to us, but it
isn't a focus. If FreeBSD makes sufficient progress with bhyve then it
would probably wind up getting ported to DFly eventually. But I view
VMs as creating the same sort of continous catch-up work (in terms of
what and how well hardware gets emulated, and how much of the real
hardware is supported) that new chipsets create for driver developers.
I don't think it's healthy for developers to have to spend their whole
lives playing catch-up.
What I would rather have is an OS core that is stable enough that it
just doesn't crash any more. On the server side of the equation I think
the goal is possible. Servers basically only have to deal with network
and disk controllers, not sound or video or other hardware, so the
drivers used by servers are relatively more simple and can slowly
approach a bug-free state. Once an operating system reaches that point,
there is no reason to run the OS itself under a VM even in huge deployments.
I would rather that we focused on better fire-walling of services within
the infrastructure of the operating system rather than punting on it and
running each service in its own VM with its own copy of the operating
system.

Now that DragonFlyBSD's kernel has concurrent and parallel features
done as best as possible, main focus seems to be shifting to
HAMMER2, am I correct?
Can we expect to have DragonFlyBSD as a virtualization host (besides
jails) after work in HAMMER2 is done? What can we expect, xen as
dom0, bhyve or other technology? Is there some time horizon for this?
Thanks for any info,
Luis
