I have been looking at NetBSD, it supports Xen dom0. Like you, I wish for a solid, slim core system with adequate virtualization support to run Linux if necessary. I have also been looking at microkernels for some time now, Minix has some fascinating reliability features[1][2] built in and plans for more.

But the monolithic Linux kernel (now with systemd) has become unmanageably large so now we consider virtualization, on top of a slimmer core, with its own consequent performance loss, for the sake of reliability.
