Interesting! Thanks for the hint.

However, that's not what I'm looking for. I'm interested in running
a type-1 Hypervisor with FreeBSD as the host (as in Xen/Dom0) and
all kinds of DomU clients (FreeBSD, Linux, Windows, etc.). The host
machine will be a server with at least 90 GB RAM (later up to 512 GB)
and plenty of SAS/SATA drives.

Since I'm considering running ZFS on those drives at the host level,
and serving the clients on top of that, FreeBSD as Xen/Dom0 seems
like a good idea... if it was already available. However, I'm not sure
yet if ZFS would be advisable for this scenario or if it would kill
performance. If not, I wouldn't mind running Xen/Dom0 with some
lightweight Linux distro as host, and FreeBSD as DomU. It wouldn't
be as nice as a native FreeBSD setup, but it's better than nothing.
