Greetings. I am having a show-stopping issue with the combination of VirtualBox 6.0.2, a Windows 10 guest and a Linux host. It only works if I have the video set to VBoxVGA, but then it works very slowly. So, having read about similar issues others were facing, I tried switching to VBoxSVGA, but then I don't even get a booting system. It is just black with no virtual drive activity, completely dead. I get something between that if I try VMSVGA, with a booting system (I see a lot of virtual drive and network activity, and can even hear audio when I tell VBox to send the shutdown signal) but still just black on the virtual display.

I am also using the EFI boot option for this VM, in case that makes a difference. I can't very well switch that to BIOS, as the system will then not boot at all.

What could be wrong with this combination? Is it the EFI option? I have Windows 7 on a laptop running the same Linux (Fedora 29), and it does work with VBoxSVGA. I'm sure I have it using BIOS booting. Is it that or is it a Windows 10-specific issue?

Going by the changelog for version 6.0.4, it looks like EFI will likely be the culprit since it just enabled "basic support" for VMSVGA with EFI, but I will have to wait for a future update to fix VBoxSVGA with it. There was also a driver issue when attempting to use VMSVGA, such that the guest additions would fail to update or install clean while using VMSVGA after removing the old additions.
