“loaddev" seems to be a read only property… :(

> Another solution, though not pretty, is to build a version of userboot that doesn't have ZFS enabled. Modify sys/boot/userboot/userboot/Makefile and remove the MK_ZFS section, and copy userboot.so from the build to /boot/userboot.so and the host. This should give you back the behaviour from 10.0.

OK, I had no sources to compile so I did a very bad thing and I know I’ll go in hell for this but…

I copied userboot.so from another FreeBSD 10.0 machine and substituted /boot/userboot.so from the host. Restarted the VM and it worked like a charm.

You’re going to fix this before 10.1 final, RIGHT?? :-)

Do you think this modification may result in a non-booting host machine?
