I do have a similar setup on one box, albeit on a SPARC Solaris 10
for a Solaris 8 branded zone (evacuation of an older server to newer
hardware), and the zone manifest (/etc/zones/zonename.xml) contains:

<device match="/dev/zvol/rdsk/pool/zones/local/colonel-data/chunk1"/>

The volume has no special properties set:

# zfs list -r pool/zones/local/colonel-data

zfs get all pool/zones/local/colonel-data/infx-chunk1

In particular, the "zoned" property is "off" on both the volume and
its higher containers.

This setup works, despite the fact that the branded Solaris 8 image
has of course no direct support for ZFS, so delegation of datasets
was not an option (either devices, or lofs-mounts, from the GZ into
LZ should have worked and did in fact work).

Now, this is indeed a different OS, but the basics like this should
be the same. Try starting "zlogin -C zonename" before booting the
zone, this may log something about some errors that may be in the way?
