I run Virtualbox in MacOS on a Macbook Pro 13-inch 2017 with 8 GB RAM and High Sierra. I installed a Manjaro Linux VM the other day, it is the XFCE-version, I allocated 30 GB for the disk and 2 GB for the memory. The Manjaro guest uses excessive CPU any time that I select a desktop icon. I can work with all applications and launch applications from the XFCE panel och whisker menu without problems. But just selecting a desktop icon on the guest halts the VM and it freezes.
CPU use on the guest is low, but the host indicates 140-170% CPU use by the VM.
Any idea what to do?

Re: Linux guest uses excessive CPU on host
We need to see a complete VBox.log, from a complete VM run, where the problem occurs:
- Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
- With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
- Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

I attach a log produced according to the instructions.

Re: Linux guest uses excessive CPU on host
140% - 170% ??
I would suspect it's your Intel OpenGL support on the host. I would test the effect of disabling 3D acceleration. I'd also test the effect of bringing the guest additions up to something reasonable: 5.2.0 is pretty ancient for a host running VirtualBox 6.0.4.
If that doesn't fix it then I'd test the effect of disabling audio.
And note: this is a 2 core host, there's a limit (of one) on how many OS's it can run smoothly, simultaneously. Two OS's is always going to cause visible lag.
