I'm using VirtualBox 4.0.8 with Windows 7 Enterprise 64 bit host and debian 6.0.1a amd64 guest (in CLI mode).
I installed Guest Additions and it seems to work, at least partially, as I have successfully setup a shared folder between host and guest.
However every time I boot the guest, I get the following messages on console:
Starting VirtualBox Guest Addition service ...done. startpar: services(s) returned failure: vboxadd-service ... failed!
There is no additional error message in any of the logs (checked syslog and VBoxGuestAdditions.log)
Additionally, I'm unable to use shared clipboard between host and guest (it's set to bidirectional, but neither direction seems to work). I assume this might be related to the service start failure.
Any idea how to fix this?
