Altering the defaults for unattended installs

[salan]

Is there a way to change the defaults for unattended installs wizard?
Things like the user and password etc.
when I am testing new builds/setups I sometimes use the UA wizard but often forget to change things like the user and pass to what I use as defaults. Then other scripts I have to configure the guest (add apps for example I always want) fail.
It's a minor thing but would be great if there was a way to set these defaults.
Thanks

The only thing I can think of to try tweaking is the scripts in the default installation folder Oracle\VirtualBox\UnattendedTemplates.

In the unattended installation templates, look for strings beginning with "@@VBOX_INSERT_" and ending with "@@", containing "USER_LOGIN", "USER_PASSWORD" and "USER_FULL_NAME" in between (and sometimes more).

Many thanks.
Would an upgrade to VB over write these though?

Where on a linux host are these please?

[scottgus1]

I'm not certain. Find where Virtualbox is installed. "UnattendedTemplates" will be inside that folder.

The package manager of your Linux distribution would tell you.

On Debian/Ubuntu hosts: /usr/share/virtualbox/UnattendedTemplates.

Yes.

Thanks I had already found them there but looking at the scripts, I was a bit confused.
I could see the variables but not where they were defined i.e. initial values which is what I assume I would change to the defaults I want to use.

This may or may not be of some use:

I have used it to create install bath file on Windows to install a bunch of Linux & !Intel ISO's.

The scripts are what the corresponding guest OSes expect as a parameter file, so their structure is defined by the respective guest OS. VirtualBox "only" replaces the variable names with the contents given in the VirtualBox Manager, and provides the scripts to the guest OS installer.

Simply replace the variable names with your intended username and password inside the templates, for example replace "@@VBOX_INSERT_USER_LOGIN@@" by "myusername", and VirtualBox won't insert the username and password you forget to change in the VirtualBox Manager (defaults: "vboxuser", "changeme").
