Preparing the machine configuration

• It is nicer if the machine is a QEMU guest. On NixOS:

  services.qemuGuest.enable = true

• Choose static IPs for your machine. The IPv4 and IPv6 subnets available for Fediversity testing are:

  • 95.215.187.0/24. Gateway is 95.215.187.1.
  • 2a00:51c0:13:1305::/64. Gateway is 2a00:51c0:13:1305::1.

Upload your ISO

• Upload your ISO
• In the node you want, `local` storage. ISO images. Upload. You can also download from URL.

Creating the VM

• Click “Create VM” at the top right corner.
• Tick “advanced” at the bottom.

uncheck, we will handle the firewall on the VM itself

Install and start the VM

• You see the VM on the left side.
• Click, go to console, start it.
• Install it

• Once the VM has been installed:

  • Go to the VM, Hardware, remove the CD/DVD Drive.
  • Switch bridge to public vnet1305
• Datacenter > SDN > VNets

Remove the VM

• Click on the VM. Make sure it is shut down.
• Shutdown sends a sigshutdown. If the machine doesn't listen to it, use the tiny arrow, choose Stop, check overrule and click.
• More > Remove. Enter the ID. Purge from job. Destroy unreference disks.

Move to other node

• Make sure there is no ISO plugged in.
• Click on the VM. Click migrate. Choose target node. Go.
• Since the storage is shared, it should go pretty fast (~1 minute).
