Host is running in portrait mode (1080x1920). I'm trying to get the guest into portrait mode too. So after reading this

https://superuser.com/questions/325954

I did this :

Code: Select all

VBoxManage setextradata "<vm-name>" "CustomVideoMode1" "1080x1920x32"

This has no effect on the orientation of the guest, but even worse my host CPU soon goes over 100% for VirtualBox.

I guess I can live without portrait on the VM. I usually run it headless anyway, but I can't live with this CPU cranking.

What can I do?

When you put the VM into Fullscreen, does it follow the Portrait mode of the host monitor?

[stephenboston]

No it does not. The guest in full screen is in landscape with a horizontal scrollbar.

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show in Explorer/Finder/File Manager. In the "Logs" subfolder, zip the VM's "vbox.log", and post the zip file, using the forum's Attachments tab. (Configure your host OS to show all extensions so you can find the "vbox.log", not "vbox.log.1", etc.)
