Error launching VB after restoring linux system: Kernel driver not installed (rc=-1908)

[ripstop]

I'm running a Windows guest on a Ubuntu host. I recently restored backups of the Ubuntu host including all the data, which includes VirtualBox app and the virtual machines. The host restore went fine, but when I launch VB, I receive the following message:



From a little googling, it doesn't seem there is any consensus on a good fix that doesn't require running rcvboxdrv after each boot. Any suggestions?

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Turns out the suggestion made by the popup worked for me, even though it failed for a lot of people and seems to be a known bug. https://www.virtualbox.org/ticket/15055

The bug was fixed after version 5.0.14, and I'm on 5.0.20, so it's all good.

I ran

Code: Select all

sudo /sbin/rcvboxdrv setup

and it completed without error.
