I have made a this VM about 3 moth ago.
From time to time, when I use the bidirectional clipboard the VM suddenly is down (broken), and I have to start it again.

And when I start my Linux VM guest in my Linux host, then I get this error: Is there a way to solve this?

Thank you.

Those error lines are from the Linux OS, not Virtualbox. These lines show up in my Linux guests all the time, and the Linux OS proceeds to boot up normally.

If your Linux guest boots normally after these error lines, then you can safely ignore this error message.

I agree with scottgus1 in that it's a systemd error message which is common across all Linux VMs I've tried which use systemd if the VirtualBox recommended/default video setting for Linux (VMSVGA) is used. AFAIK it's totally harmless, but can be made to disappear by using 'pure' VBoxVGA (Note: NOT VBoxSVGA, unless it's Manjaro Linux) rather than VMSVGA. That, of course, means you can't then use 3D, which distributions such as Linux Mint (Cinnamon) demand, unless you want suffer a performance hit by switching to software rendering mode.

OK. Thank you all.
