[WorksForMe] 6.1.0_BETA2 r134346 Denying userspace vmm call type 0x000051

Post by hotjava1231 »

Host OS is Arch Linux.
Guest VM OS is Arch Linux.

After starting or rebooting Guest VM, I get this error message printed on the console login prompt : "Denying userspace vmm call type 0x000051"
I think that this error message came up when I upgraded Guest Additions to r134334 (BETA2 VBoxGuestAdditions_6.1.0-134334.iso).

Still getting this. It seems that as if the Guest Additions were built for older version of VirtualBox.

I have downloaded newest version from this link: https://www.virtualbox.org/download/tes ... 134650.iso

EDIT : I forgot install linux kernel headers. Now it works!

The Guest Additions (GAs) are build on-the-fly, they don't come pre-made, so I can't see how this could have happened...

klaus at the #vbox-dev IRC channel said on this matter :
I assume you had some old vboxdrv.ko loaded, and that one didn't handle the call from a newer vbox version, and this is the slightly cryptic way to let you know ;)
