Another (pretty vanilla) use case. I'm using nvmm on two NetBSD/amd64
10_BETA boxes - a laptop and an HP Microserver.
Both cases run a single Ubuntu VM to run java code which links to
native machine learning libraries.
I did have the HP Microserver setup under 9.x running multiple VMs,
with the qemu monitor hooked up to a per VM file to make it easy to
shutdown and reboot, but I've not bothered with that after the upgrade
as its not been needed.
I migrated the HP Microserver from xen under NetBSD-9 as it would hang
occasionally and not reboot cleanly, issues that went away with nvmm
