27.5.2 Virtual machines
Now you can create a virtual instance. Select 'Virtual Machines' and then click on 'Create' to set the basic parameters of the machine.
Now you can set the basic parameters of the machine. Please take into account the following points:
- ISO file: Under point 1, set the installation disc (ISO file).
- Hard drive: In point 2, you can determine the format of your hard disk. Choose between 'qcow2' and 'raw'. If you select 'qcow2', all changes to the virtual disk will be logged. This option is particularly useful if you want to test systems. This allows you to save a copy of the current state, which you can go back to later if necessary (e.g. if an update fails). This is not possible when you select the raw format. However, the advantage of the raw format over qcow2 is its higher efficiency under a higher load and over a longer period of time.
- Network card: Under point 3, set the virtual card that can be addressed later by the operating system. You have the choice between the rtl8139 or e1000 network card. While the first option does not require any drivers even in older operating systems, the e1000 is faster (1Gb card), but usually requires specific drivers.
: Important: To save your settings, you have to click on the red 'create' button at the bottom of the screen. You will receive a confirmation that the instance has been set up.
If you look at the text of the message, you will see that the command corresponds to what is necessary to create an appropriate instance on the console.
