Mac host: Virtualbox creates empty processes and prevents restart/shutdown

[Blownauratone]

Macbook Pro 2012, OS X 10.9 Mavericks, newest Vbox and extensions, Windows 7 VM

I've seen this issue talked about throughout the VB forums and elsewhere, and so far there has been no resolution. My particular problem with this issue comes from the fact that I am a documentation specialist, and so must work extensively with unfinished software and drivers, which create instabilities often—requiring restart.

When I try to restart, Virtualbox's processes will not quit and cannot be stopped by any method, GUI or command line. I am forced to hard-reset my computer, which creates a host of other problems and causes a constant need for system maintenance.

I hope very much that there is a resolution for this issue! I otherwise prefer Vbox to all other virtual machine solutions, and spread its gospel with all of my friends in tech.

I don't understand your problem. Can't you start your VM(s)? Could you explain that 'empty processes' bit better? I don't find any useful information in the excerpt of your 'dmesg' output except that you are apparently using VBox 4.3.24. Where is the VBox.log file?
