FYI Andre sent me a disk image:

$ qemu-img info FreeBSD_ZFS-test.qcow2 
image: FreeBSD_ZFS-test.qcow2
file format: qcow2
virtual size: 1.0G (1073741824 bytes)
disk size: 1.0G
cluster_size: 65536

$ guestfish --ro -a FreeBSD_ZFS-test.qcow2 

Welcome to guestfish, the guest filesystem shell for
editing virtual machine filesystems and disk images.

Type: 'help' for help on commands
      'man' to read the manual
      'quit' to quit the shell

I tried opening it with virt-rescue, but for some reason the zfs-fuse
daemon would not start, and hence other commands such as zpool didn't
work.  I opened a bug to look at enabling ZFS:
