If you use BHyve to boot FreeBSD, the loader which is used is in /usr/src/sys/boot/userboot , and this loader does not support a complete ZFS-only install. I recently tried to do this, and the install worked (with 4G of RAM), but when I tried to reboot the BHyve VM, the VM did not boot. If you look at: https://admbugs.freebsd.org/show_bug.cgi?id=428#c7 you will see I had to use a variation of these steps: https://wiki.freebsd.org/RootOnZFS/UFSBoot where the /boot directory which contained the kernel and loader was on a UFS partition, but everything else was on ZFS. That's the only way I could get the BHyve VM to boot, with userboot. -- Craig
