[vbox-dev] Framebuffer implementation cannot power up a vm (VERR_VM_DRIVER_NOT_ACCESSIBLE) with VirtualBox 5

Mon May 9 05:53:11 GMT 2016

Hi,

I previously posted some weird permission behavior on Ubuntu 14.04 but
since I could dig to the end of that I just decided to reinstall the
machine with Ubuntu 16.04 and VirtualBox 5. Now my custom framebuffer
implementation fails to power up the machine and I see
VERR_VM_DRIVER_NOT_ACCESSIBLE in the virtual machine log, however if I
start the machine from the GUI everything runs fine.

It seems true that only root has access to the /dev/vboxd* devices (at
least according to ls).

ls -l /dev/vboxd*
crw------- 1 root root 10, 55 May  9 00:26 /dev/vboxdrv
crw-rw-rw- 1 root root 10, 54 May  9 00:26 /dev/vboxdrvu

But I do not get why the GUI frontend is able to start the machine and my
frontend is not. I tried chmod u+s on the binary but that did not help. Are
there any new requirements for 3rd party executable that launch the XPCOM
interfaces?

VBox.log when my framebuffer fails:
