I am inclined to think that IT IS an nvidia issue because I have 2 machines, both with:
- FBSD 8 revision (FreeBSD 8.0-STABLE #0 r204106M: Sat Feb 20 03:29:09 UTC 2010) svned and compiled on the same day on both machines.
- KDE 4.3.5 with openGL, composite and direct rendering enabled on both.
- Vbox 3.1.4 (plus the same version guest additions on each guests i.e. XP, Win7 and Fedora).
- Both machines run the SAME 3 vdi guest files.
One has an Nvidia 9800 GT and the other an GM45 intel.
Only the Nvidia machine always freezes with virtual box
