Setting up VirtualBox

Getting started

First, download the KolibriOS distribution of your like, you may chose between a floppy or CD distribution.
The downloads on the site are packed with 7-zip, you'll need 7-zip or another unpacker to unzip the file.
Extract the file called kolibri.img (for the floppy distribution) or kolibri.iso (for the CD distribution) to a directory on your harddrive.
Remember where you have put it.

Creating the VM

Then, after installing VirtualBox, click the 'new' button.

Type the name for your virtual machine and select the OS type.

Choose the amount of RAM you want to use, 64 Mb is enough.
Unless if you want to run DOSbox or other heavy applications, 256 Mb may be a better setting then.

We dont need a harddrive.
If you'd like to use a harddrive, you will need another virtual OS to format it, as KolibriOS currently does not have a format program.

If you chose not to use a harddrive, you'll get this warning, just continue.

Mounting the virtual floppy/cd image

Now that the virtual machine is created, we need to attach the CD or floppy image.
The CD image comes with some extra programs, but it's easier to update the floppy image when you plan to do some development.

If you chose to use the CD image, simply select the CD/DVD drive and add the iso as shown in the picture.

If you however would rather like to use the Floppy image, we'll need to add a floppy controller first.

Once the floppy controller is added, attach the kolibri.img virtual floppy as follows.

USB

KolibriOS has USB support for quite some time now, and it can be useful to mount a USB device connected to the host machine, onto the virtual machine.
You will need to enable USB support in the virtual machine.
When you're using linux, you'll also need to be a member of the vboxusers group for USB to work.
To become a member of this group, you may use the following command: sudo usermod -aG vboxusers <username>
A detailed article is available on this matter: http://www.dedoimedo.com/computers/virtualbox-usb.html

Since version #4529 it's possible to use the VirtualBox USB-tablet input device.
When using this device, it's no longer needed to capture and release the pointing device to the Guest OS, which may be convenient.

First run

Now just click start, and let it fly!
