#16206 worksforme vboxvideo.ko unable to be inserted into kernel on CentOS 6/7 -> expected behaviour hsundara
Description

Guest: CentOS 6/7, software development workstation install (with Gnome GUI) GuestAdditions: Installed and rebooted successfully, no errors.

Trying to access VM via RDP, authentication method: NULL

The screen resolution doesn't change. on ubuntu 16.04 for instance, the screen resolution changes automatically.

Looking at list of modules inserted, I see vboxsf and vboxguest but not vboxvideo.

On CentOS 7 find /lib/modules | grep vboxvideo /lib/modules/3.10.0-327.36.3.el7.x86_64/misc/vboxvideo.ko insmod /lib/modules/3.10.0-327.36.3.el7.x86_64/misc/vboxvideo.ko insmod: ERROR: could not insert module /lib/modules/3.10.0-327.36.3.el7.x86_64/misc/vboxvideo.ko: Invalid parameters

On CentOS 6 find /lib/modules | grep vboxvideo /lib/modules/2.6.32-642.6.2.el6.x86_64/misc/vboxvideo.ko insmod /lib/modules/2.6.32-642.6.2.el6.x86_64/misc/vboxvideo.ko insmod: error inserting '/lib/modules/2.6.32-642.6.2.el6.x86_64/misc/vboxvideo.ko': -1 Invalid parameters

The module is built correctly but doens't get loaded, which means I don't get the RDP resizing that I really want, in fact, that's the only reason I installed guest additions.

#16204 fixed Virtualbox Driver doesn't have WHQL Certificate Dr.Thril
Description

Driver signing changed in Windows 10 1607 Version:

MSDN Blog

Microsoft said:


Starting with new installations of Windows 10, version 1607, the previously defined driver signing rules will be enforced by the Operating System, and Windows 10, version 1607 will not load any new kernel mode drivers which are not signed by the Dev Portal. OS signing enforcement is only for new OS installations; systems upgraded from an earlier OS to Windows 10, version 1607 will not be affected by this change.

If your driver doesn't have Microsoft Windows Hardware Publisher Certificate (For Example:IDM Browser WFP Driver), Windows will block the installation of this driver.

So Does Virtualbox should get a Microsoft Certificate?
