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 David
