here's my experience with the VirtualBox 3.0.0 Beta1 and 2 releases on Mac OS X Leopard with a OpenSolaris 2009.06 guest, running in 64 bit mode:
- Previous stable environment: VB 2.2.4, with 2.2.4 guest additions installed.
- Upgraded to 3.0.0b1. Guest works fine.
- Switched 3D accel on, doesn't work (black screen, no X).
- Switched SMP support on, seems to work on a kernel level (it boots) but still no luck with X. Same with 3D off.
- Upgraded to 3.0.0b2. Same as above
- Upgraded the guest additions to the ones shipped with 3.0.0b2
- Graphic rendering is broken: The upper 10th of the screen displays a very distorted view of the login screen, otherwise the system seems to work ok. This is independent of 3D accel or SMP on/off
- Downgraded to 3.0.0b1. Still the same.
- Downgraded to 3.0.0b1 guest additions. Still the same.
- Installed the 2.2.4 guest additions into the machine running on 3.0.0b1. Everything ok again, but not using 3D nor SMP any more
Will upgrade to 3.0.0b2 but leave the guest additions alone for now.
Thanks,
Constantin
