I've noticed the same problem with a MSWindows VM on a laptop, but only when the screen resolution for the VM is anything other than full screen on the host. The starting ritual to rectify this involves pressing Esc repeatedly as Tianocore screen starts to come up, then select 'Reset', which resizes the Tianocore window and when the MSWindows VM starts I use Ctrl+Alt+F to enter full screen mode. If I don't do this the VM window is small(er), the resolution will not resize to full screen even when the window is maximised and the mouse is sticky/jumpy and its real position displaced on the guest's screen - I have to guess where it will actually land before I click on anything. Other OS VM guests, e.g. Linux, *BSDs, Android, etc. do not exhibit this problem. > Plan B) According to the ARCA NOAE website > https://www.arcanoae.com/wiki/arcaos/installation-planning/virtual-machine-c > onfiguration/oracle-vm-virtualbox/ ArcaOs can be installed in a VirtualBox > VM, masquarading as OS/2 (I did say it was backwards compatable). > > Are there any booby-traps to watch out for? What I'm most concerned > about is the default "qt5" USE flag. Is VirtualBox usable without the > qt5 GUI? I use the Qt5 GUI on VBox which offers a very user friendly management interface. However, recently I am not able to boot MSWindows OSs. I think, but I'm not sure, some recent kernel settings have hardened (Spectre_v2?) and it seems the MSWindows OS requires access to the host which is no longer allowed. VBox complains about AHCI driver corruption, kernel and system problems and gets into a loop of trying to auto-correct whatever has the problem - but fails. I haven't tried reverting kernel settings to see if the MSWindows VM will be able to run normally again. I'd be interested to find out if there are any workarounds to get these VBox VMs to run again, but haven't had time to look into it. --nextPart3192709.44csPzL39Z Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
