3 Configuring virtual machines

3.3.3 “Description” tab

Here you can enter any description for your virtual machine, if you want. This has no
effect of the functionality of the machine, but you may find this space useful to note
down things like the configuration of a virtual machine and the software that has been
installed into it.

3.4 System settings

The “System” category groups various settings that are related to the basic hardware
that is presented to the virtual machine.

Note: As the activation mechanism of Microsoft Windows is sensitive to hard-
ware changes, if you are changing hardware settings for a Windows guest,
some of these changes may trigger a request for another activation with Mi-
crosoft.

3.4.1 “Motherboard” tab

On the “Motherboard” tab, you can influence virtual hardware that would normally be
on the motherboard of a real computer.

Base memory

This sets the amount of RAM that is allocated and given to the VM

when it is running. The specified amount of memory will be requested from the
host operating system, so it must be available or made available as free memory
on the host when attempting to start the VM and will not be available to the
host while the VM is running. This is the same setting that was specified in the
“New Virtual Machine” wizard, as described with guidelines under chapter

1.6

above.

Generally, it is possible to change the memory size after installing the guest
operating system (provided you do not reduce the memory to an amount where
the operating system would no longer boot).

Boot order

This setting determines the order in which the guest operating system

will attempt to boot from the various virtual boot devices. Analogous to a real
PC’s BIOS setting, VirtualBox can tell a guest OS to start from the virtual floppy,
the virtual CD/DVD drive, the virtual hard drive (each of these as defined by the
other VM settings), the network, or none of these.

If you select “Network”, the VM will attempt to boot from a network via the PXE
mechanism. This needs to be configured in detail on the command line; please
see chapter

8.5
