Installing OpenSolaris on Parallels Desktop on Mac

To try some things I wanted to install OpenSolaris 2009.6 on Parallels Desktop on my Mac.

Install of OpenSolaris itself went well, but network was not available.
Searching around the net led to

http://dlc.sun.com/osol/docs/content/2009.06/getstart/parallels.html
and finally

http://kb.parallels.com/de/7060 (or English: http://kb.parallels.com/en/7060)

But still no avail.

It turned out that the script change is almost complete, but is missing
one additional line. Below "Compiling driver ..." it should read

cd $tmpdir/$driver && /usr/ccs/bin/make install > /dev/null

After this change dladm show-phys shows the interface and ifconfig ni0 plumb is able to use it. After a reboot, networking is working :-)
