Download glibc-zone.tar.gz and extract into /usr/lib/brand:

  # cd /
  # wget http://csclub.uwaterloo.ca/~dtbartle/opensolaris/glibc-zone.tar.gz
  # tar -xzf glibc-zone.tar.gz

Create the zone:

  # zonecfg -z glibc
  glibc: No such zone configured
  Use 'create' to begin configuring a new zone.
  zonecfg:glibc> create
  zonecfg:glibc> set brand=glibc
  zonecfg:glibc> set zonepath=/opt/glibc-zone
  zonecfg:glibc> add net
  zonecfg:glibc:net> set address=129.97.134.99
  zonecfg:glibc:net> set physical=rge0
  zonecfg:glibc:net> end
  zonecfg:glibc> verify
  zonecfg:glibc> commit
  zonecfg:glibc> exit

(Substitute rge0 for your driver)

Install the zone:

  # zoneadm -z glibc install
  # sudo mkdir /opt/glibc-zone/root

Eventually this would debootstrap into the zone. For now you can just follw
cross-compiling.README to create a chroot in /opt/glibc-zone/root.

Finally boot the zone:

  # zoneadm -z glibc boot

You can connect to the console via:

  # zlogic -C glibc
