That was the highest-resolution graphics mode which all VGA chips (and monitors) could handle. you want to run the machine headless or over SSH and don't need the overhead of it emulating graphics.The so-called "VGA" resolution is 640x480. may not be as fast as VBox cards because it's trying to be compatible with something else.probably best when your VM was originally set up on VMWare and has their tools installed.(by inference) slightly lower performance but more compatibility with older OSes.Display Settingsīut they do tell you quite explicitly when you should prefer them: Only use it if you provide a real GPU via PCI passthrough, or if your system absolutely doesn't need a GPU. This is, obviously, no emulated graphics at all. allow to make use of VirtualBox-specific additional features. Also, because it's still VMware SVGA emulated by VirtualBox, choosing this option and using the VirtualBox driver may still have advantages over the VMware one, e.g.The advantage of this mode is that you can upgrade existing VMs (which previously used VBoxVGA and had the VirtualBox Video driver installed) and they don't lose their graphics in the process – they still see the same device, until you upgrade the "guest additions" at any later time to enable 3D acceleration.This is the default for Windows guests.This provides a hybrid device that works like VMSVGA (including its new 3D acceleration capabilities), but reports the same old PCI VID:PID as VBoxVGA. (I plan to test this with Windows 9x, which is otherwise a massive pain to get even VESA graphics working with VirtualBox) It might also have the advantage of supporting old operating systems which had VMware guest additions available but not VirtualBox guest additions.Supports OpenGL 2.1 on all Windows and Linux guests. ![]()
