Unable to run guest on Host with kernel greater than 5.9.16

Post by DanglingPointer »

I have an Ubuntu 18.04 host with multiple mainline kernels. I can run Ubuntu Mate 20.04 guest on any kernel less than 5.10. Any kernel from 5.10+ fails
Basically I can't run guests on mainline kernels 5.10.x and 5.11.x

I get the following error...
kernel driver not installed (rc=-1908)
I have Virtualbox v6.1.18r142142(Qt5.9.5)
The latest kernel that works ok is 5.9.16

Appreciate any help! Thanks in advance!

Help anyone?

Has anyone gotten VBox to work with 5.10.x or 5.11.x?

If so how did you install/configure it?

I finally fixed it and got it working with the latest 5.10.25 mainline kernel.

All I had to do was run:

Code: Select all

$ sudo vboxconfig
on the host. Then in the guest I re-rerun the guest addition script.

It works with 5.10.x but not 5.11.x
When running 5.11.x running the above command fails complaining about some missing header. Oh well I'm happy with the latest 5.10.x for now.
