OpenSolaris in VirtualBox
I've been playing around today with VirtualBox, after finding that the latest version claims to run on Solaris 10.
Which is true, but you need to jump through a few hoops first.
First, you need to make sure that libGL.so can be found. I guess this varies a bit depending on whether you're using mesa or have the nividia drivers, but I ended up setting LD_LIBRARY_PATH_64 to /usr/X11/lib/amd64.
Then you need libXinerama; if you're running an older version of Solaris (my test machine was running S10U3 == 11/06) then applying patch 125726-02 will do the trick.
Then if you're running 64-bit you'll need a copy of libdlpi. I just snarfed a copy off one of my test opensolaris boxes (actually indiana preview 2 - I have seen comments that the one from the official OpenSolaris release won't work as it's too new).
(Yes, I realize there might be a bit of a chicken and egg situation there!)
Then I tried booting the indiana preview 1. Which worked just great. No network, but I expected that. The only glitch I had was the key to escape from the guest - which is set to Right Ctrl by default, which I discovered I don't have. I reset that to some other key that I do have and don't use for anything else.
Having learnt from that, I had a go at the OpenSolaris 2008.05 release having found a CD that I had brought back from CommunityOne, and that worked fine (and picked up the network).
