Please verify first that it also happens with a supported host (Linux, Windows, Mac) and then report it upstream at VirtualBox or probalby in that case better DragonflyBSD. > 2.

Those problems are hard to find and usually can only be fixed if a developer can reproduce it. I have also seen a 100% cpu problem recently but as a workaround it helped to pause the VM and resume it after restarting virtualbox. You could check VBox.log or any debug logfiles if they have reported anything abnormal. > 3. I see that my working machines after correct guest shutdown ends > up throwing 'Segmantation fault'. Should I report that too? During the call for testers we recommend to always build with DEBUG option enabled to spot all errors but in some cases that triggers assertions that are uncritical and sometimes even bugs in the debug code paths. So if you see a Segmentation fault please send us a stacktrace from the core file (already described somewhere in the thread how to get a core file and stacktrace) so that someone can check that. -- Bernhard Froehlich http://www.bluelife.at/
