[vbox-dev] Location of VirtualBox configuration file

We continue to have problems with this location issue.

In our labs the students have a profile script that set HOMEDRIVE to h: and HOMEPATH to \. I am expecting directories to be created and files stored in the locations H:\.

This is not the case.

Instead directories are created and files stored in

c:\users\xxxxxx\.virtualbox , etc

I might be able to understand this behaviour, but we are finding that the global configuration file is reinitialised every time the VirtualBox is started - the previous configuration file being renamed to "-prev".

Even if the HOMEDRIVE is not respected, I would at least expect the global configuration file to be used again.

Our environment is Windows 10.

We are investigating, but this is the information we have so far on the issue.

We have yet to try VBOX_USER_HOME as a workaround, but I wanted to bring the other behaviour to your intention in case it is affecting others.

You may understand the frustration of our students having to set up the global and VM configuration every time they use VirtualBox. I have a mutiny on my hands!

Regards

Hi Malcolm,

VBOX_USER_HOME also should work on Windows if you set this as system-wide variable. This of course means that this only can point to one profile at a time.

If you mount the current user's profile always to the same location (e.g. "X:\VirtualBox") you can give this at least a try.

Kind regards / Mit freundlichen Grüßen

Max's answer is correct for every supported host OS besides Windows. As
usual, on Windows everything is more difficult. On this OS it's COM
which starts the API service, VBoxSVC.exe, and I don't know a way right
now to reliably pass it the required env variable...

Hi Malcolm,

You can change the location using the ||VBOX_USER_HOME|| env variable.

Dear All

Although VirtualBox holds a parameter for the location of the
configuration files of the virtual machines, is there any way to
control the location of the configuration file of Virtual Box?
Currently it installs itself in a directory ".VirtualBox" in the
user's default directory.

Is there a switch or otherwise to place this directory and its
configuration file in another specified location?

I ask this because we are using Virtual Box with students in a lab.
They are allocated a home drive which is connected every time they
log on to a machine, but we do not operate roaming profiles. Although
they can retain the VM configuration directories and files by
configuring to their home drive, they "lose" the Virtual Box
configuration file every time they move to another machine.
