16206	vboxvideo.ko unable to be inserted into kernel on CentOS 6/7 -> expected behaviour	hsundara		"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."	defect	closed	guest additions/x11/graphics	VirtualBox 5.1.8	worksforme			Linux	Linux
