VirtualBox Manager not showing machines

Post by joebug »

I can't seem to access or view any machines on my system even though they are registered in VirtualBox. Have tried updating VirtualBox, restarting, removing drive with machines and reconnecting as well as dragging from sides of window but can't seem to figure this out. I should also mention that my machines are being stored on an external SSD. Any help is massively appreciated. Cheers.

The VirtualBox Manager window usually shows up to three columns, separated by vertical lines called splitters. The left splitter probably was moved to the left window border and disappeared, and on macOS hosts with Retina displays you cannot grab it with the mouse to get it back.

Please reboot your host to ensure that no VirtualBox component or VM is running. Open a terminal and execute the following commands:

Code: Select all

VBoxManage getextradata global "GUI/LastWindowPosition"
VBoxManage getextradata global "GUI/SplitterSizes"
The output will look like the following, giving you 4 and 2 numbers:

Code: Select all

Value: <x>,<y>,<w>,<h>
Value: <xa>,<xb>
If <xa> equals 0, enter the following command, replacing "<...>" with some sensible values, for example:

Code: Select all

VBoxManage setextradata global "GUI/SplitterSizes" "<w*1/3>,<w*2/3>"
When you start the VirtualBox Manager afterwards, it should look normal again, and you can move the splitters as you like.
