Creating your own virtual machine

There are situations where you want to have a system, which you can manage by yourself as 'root', e.g. to install and test software. In such cases a virtual machine is a good idea. To create your own virtual machine on an ISG D-ITET-managed Linux client proceed as followed:

  1. On one of the machine's disks '/scratch' or '/scratch-second' (hereinafter referred to as: DISK) create a directory <username>. In addition create directory '/DISK/<username>/VM' to store your finally created VM.

  2. Download any operating system installation image to '/DISK/<username>'.

  3. Type following command on the console: 
    •      $ vmplayer
  4. In the upcoming window klick "Create a New Virtual Machine" and use your downloaded virtual machine image.
  5. Make reasonable settings concerning RAM, CPU and Disk (dependend on your machine's hardware setup): 
    •      RAM:  min. -> 1-2 GB    max. -> 50% of the RAM of your machine
     CPU:  min. -> 1-2       max. -> 50% of the CPUs of your machine
     Disk: min. -> 10-30 GB  max. -> reasonable percentage of your machine's disk

  6. Finally set the path of your new VM to '/DISK/<username>/VM' and start the installation process.

  7. After finishing the installation use command 'vmplayer' to start, resp. changing VM parameters in the future.

/!\ Note: 'Virtualization Technology' must be activated in the BIOS of your machine to create VMs in your environment. You can test that with following command: 

  •      $ ls -l /dev/kvm

    If this file doesn't exist, 'Virtualization Technology' is deactivated. In this case write to: support@ee.ethz.ch to make the BIOS settings accordingly.
