GL libraries not detected and none ending process.

Hi, Windows guest is unable to start with 3D acceleration enabled. Having only 2D enabled results in Windows booting to a black screen.

First symptom: Starting virtualbox on the cli gets:

$ virtualbox
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

Second symptom: Closing the GUI window does not always end the process (also experienced on a Windows host). CTRL-C has to be used.

Third symptom: Trying to start a VM with 3D acceleration gets the error:

Failed to open a session for the virtual machine win10.
The VM session was aborted.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: SessionMachine
Interface: ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}

Downgrading to version 5.1.18 resolves all of the above.

Same here. It is not dependent by the guest as I have the very same problem with a Linux guest. It is also happening with dry run using modesetting drivers and with optirun using nvidia drivers.

I am using gentoo multilib Linux version 4.10.11-gentoo-ck-dvd (root@gentoo-seitan) (gcc version 5.4.0 (Gentoo 5.4.0-r3 p1.3, pie-0.6.5) ) #1 SMP Sat Apr 22 18:29:30 CEST 2017

Could you also attach the output of

as root?

strace -s128 -o strace-vbox -f VirtualBox

[Frank Mehnert]

Thanks. /usr/lib64/dri/i965_dri.so is a regular file, is that correct? Is it also correct that this file has permissions 0777? In that case, that's the reason for your problem: The hardening code does not allow to load such libraries.

[Frank Mehnert]

Actually that file is a symlink, correct? In that case, please download the latest 5.1.x test build from here. It should fix your problem.

Same problem as above in my gentoo distro.

This is with Intel driver, but same happens with modesetting and nouveau in another box. Downgrading to 5.1.18.

Still GL error and 2d/3d acceleration doesn't work for me (gentoo, r600) with 5.1.22:

Just for completeness on version 5.1.22.

I generated via

so that vbox is running as the correct user.

Hi Frank, I'm sorry to report the same here, I am attaching my strace log

Strace log for vbox-5.1.22 with r600 on gentoo

[-DvD-]

Paolo Pedroni wrote (​https://bugs.gentoo.org/show_bug.cgi?id=616238#c13):

Seeing https://www.virtualbox.org/ticket/16693 it looks like VirtualBox refuses to load shared libraries with 777 permissions. On gentoo the dri libraries in /usr/lib64/dri are symlinks to libraries in /usr/lib64/mesa (thus 777) and VirtualBox is not smart enough to determine that they are symlinks and not actually world writable libraries, thus denying loading.

[Frank Mehnert]

It's not the 0777 symlink but it's the path the symlink points to containing '../'. We are working on a patch.

Will the fix be released in the next version of vbox or as a patch prior to a release?

Patch against 5.1.22 for resolving the symlink problems

Replying to MikeGreene:

I've just attached a patch which should resolve the problem. And the most recent 5.1.x test builds (>= 115307) contain these changes. Please verify!

[Michael Greene]

Thanks Frank, patched Gentoo VirtualBox 5.1.22 working correctly.

Fix is part of 5.1.24.
