I'm trying to get an Ubuntu VM to run well in the latest VirtualBox (5.2.2), which I installed by running
sudo ./VboxLinuxAdditions.run. The problem is I keep getting this error message when the VM starts:
VBoxClient (seamless): failed to start. Stage: Setting guest IRQ filter mas Error: VERR_INTERNAL_ERROR
The host is Ubuntu 16.04.3. I've tried two Ubuntu 17.10 distros (Lubuntu and Budgie). Both failed with the same error.
Being unable to run Ubuntu on Ubuntu should be a P0 critical issue for Oracle. What am I doing wrong?
