How to:

Create a new VM

  1. Have a login to Lamarr via Ansible
  2. Install virt-manager
  3. Connect to Lamarr with your login. (Requires your key to be there as ID_RSA) (?need to be root?)
  4. Create a new VM on Lamarr. Use local to store the virtual drives
  5. Set suitable resources
  6. Set network to join bridge br0
  7. Start and have fun
  8. Add it to this wiki page
