Today I installed Solaris 10 on Parallels, because I’ve trouble to get puppet running on my fresh leopard machine. After successful installation I realized that there was no network adapter configured. To enable the NIC I had to use /Library/Parallels/Tools/vmtools.iso as the cdrom-drive. It will be automounted. On Solaris I’ve made
# installs paralells network driver on solaris 10
this installs the correct driver for the NIC and configures it.
