Is there any way to have a guest machine have a huge resolution (like 3000x2000 or something) in VirtualBox? I'd like to be able to move around the desktop by scrolling around. It seems like it would be possible. Most importantly, I don't want the windows that are not currently being shown in the guest machine to think they are being hidden. I just want to support a very large virtual desktop.

Yes it's possible. My old machine was only capable of 1024x768 as it was a 15" LCD. Fedora worked fine on max resolution under VirtualBox (much higher than 1024x768), albeit I had to scroll the window over a lot to view things.
I would think this has to do with VirtualBox somewhat emulating a graphics adapter using your existing video memory. You will see the adapter labeled "VirtualBox graphics adapter".

1where can i change the resolution past my screen's resolution? the guest machine doesn't let me do it– ClaudiuCommented Aug 13, 2009 at 5:39

Make sure
dynamic resizing
is turned on in the settings menu. You could also just drag the guest window larger instead of setting the resolution manually.– user1931Commented Aug 13, 2009 at 5:42 -
You can't make a window larger than your screen by dragging at the corners.– JoeyCommented Aug 13, 2009 at 11:39

I did not find a way to get a higher resolution on a Linux host with a Windows XP guest - using VirtualBox only.
What I did was the following:
- I started a virtual X server with a huge resolution:
xinit -- /usr/bin/Xvfb :1 -cc 4 -screen 0 4000x3000x16
- I made the virtual X server available via VNC:
x11vnc -display :1
- Connecting to VNC server:
xtightvncviewer localhost:1
- After connecting to the virtual X server, I started VirtualBox and my machine, and set it to fullscreen.
That way I can set the screen resolution as high as I need it.
About the use case:
We use proprietary software to make a photo book. It costs quite some money to get the book printed - and the software does not offer PDF export of course.
So to get multiple cheap copies, I could buy the photo book once, disassemble it, scan all pages and print them as often as I need them. Alternatively, I could set the virtual box screen resolution really high and make screenshots of each page and print them :)

that would probably be
xtightvncviewer localhost:1
, wouldn't it?– stdcerrCommented Jan 7, 2016 at 23:30
It's possible, but why would you want this? You are going to spend more time scrolling the desktop around to find windows than anything else.

5Could be for testing, to see how software behaves in a large screen, to test web layouts, etc... Commented Aug 14, 2009 at 2:57
