On Oracle Solaris hosts, the autostart daemon is integrated into the SMF framework. To enable it you must point the service to an existing configuration file which has the same format as on Linux, see . For example:

# svccfg -s svc:/application/virtualbox/autostart:default setprop \
  config/config=/etc/vbox/autostart.cfg

When everything is configured correctly you can start the autostart service with the following command:

# svcadm enable svc:/application/virtualbox/autostart:default

For more information about SMF, see the Oracle Solaris documentation.
