VirtualBox losing left window which shows virtual machines

th flag

There are virtualbox machines list in left side, I drag window on the right side to far left, so the left side disappeared.

To reset the position of UI preference, but I didn't find the menu. So how to make the left side appear again without changing user?

This question can be resolved by changing to another user, but it wasn't a good idea.

So this question can be solved by changing the cache of UI position in current users config/cache directory.

  1. Location of VirtualBox config file. see docs.

  2. Use VBoxManage to change items(metioned by Marco above) in config file.

    VBoxManage setextradata global GUI/SplitterSizes "853,426"

  3. Restart VirtualBox.

In a very small space near the left border, the cursor turn in change in to "move line". With this you can move the line between the list of VMs and the VM Settings.

Or you change the "GUI/SplitterSizes" in the Virtualbox Config file: ~/.config/VirtualBox/Virtualbox.xml. e.g. from "0,1145" to "145,1000"
Best you make a backup of the file before changing anything. Just in case.

As @Yang (thanks!) mentioned in the comment, I add his remark:
Instead of editing the config file with a text editor it can be changed via the VBoxManage (or vboxmanage) command.

VBoxManage setextradata global GUI/SplitterSizes "853,426"

Thanks for your answer. I change the `Virtualbox.xml` but it didn't take any effect and was overwrited by the configuration which reflects the VirtualBox GUI closed before. But I found comments in `Virtualbox.xml`. **Use VBoxManage or the VirtualBox Manager GUI to make changes**. So I used `VBoxManage setextradata global GUI/SplitterSizes "853,426"` to change the config file, and it takes effects!
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
