Some or all Cooker and Rolling users may encounter problems with VirtualBox 6.1.10.

VBox guest plasma desktop crash (virtualbox-guest-additions)

Cooker Host: VirtualBox 6.1.10 VM’s do not start

For either issue the best workaround at this time is to downgrade to virtualbox v. 6.1.6. It is almost certain that for VBox guest systems you will have to downgrade virtualbox-guest-additions to 6.1.6.

You can find the 6.1.6 packages in ABF:





This workaround for VirtualBox host system does not seem to work on all hardware. We have no other workaround for this. We have not seen any reports of VBox not working in Lx 4.1. So this will affect only Cooker and Rolling users until the problem is corrected. We apologize for any inconvenience for our users.

Looks like crazy found a workaround for the problem with guest crashing with latest version of guest additions:

Open file in VM:


and comment out or remove line:

/usr/bin/VBoxClient --vmsvga || : # In case VMSVGA emulation is enabled

Then reboot.

Working for me so far in Cooker and Rolling.

Post-edit: This bug report updated accordingly:

VBox guest plasma desktop crash (virtualbox-guest-additions)

The problems in both bug reports have been resolved with OM virtualbox-6.1.12-5.

This one is over.
