Some time ago I had to write a script to convert currently downloadable VirtualBox Package into IPS Packages for Solaris 11. As I found the thing really useful, I decided to setup a repository to provide everyone easy access over these packages.
You can find the different version available here:
To install one version, follow these steps:
First, add the publisher:
pkg set-publisher -g 'http://mdma.igh.cnrs.fr/vbox' solaris
Then refresh the publisher cache:
pkg refresh --full
And finally, install the virtualbox version you want:
pkg install email@example.com
You can also install the virtualbox’s additions:
pkg install firstname.lastname@example.org
If you have any question on that, don’t hesitate to contact me.
