+#+title: Provisioning a Proxmox VM
+#+author: Kevin Muller, Hans van Zijst & Nicolas Jeannerod
+#+date: <2024-10-25 Fri>
+
+* Preparing the machine configuration
+- It is nicer if the machine is a QEMU guest. On NixOS:
+  #+begin_src nix
+  services.qemuGuest.enable = true
+  #+end_src
+- 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.
+** General
+- Node :: which actual machine you want to run; same as the ISO
+- VM ID :: Has to be unique
+- Name ::
+- Resource pool :: Fediversity
+** OS
+- Storage :: local, means storage of the node.
+- Choose what you want.
+** System
+- BIOS :: OVMF (UEFI)
+- EFI Storage ::  `linstor_storage`; this is a storage shared by all of the Proxmox machines.
+- Pre-Enroll keys :: MUST be unchecked
+- Qemu Agent :: check
+** Disks
+- Disk size (GiB) :: 40
+- SSD emulation :: check
+- Discard :: check, so that
+** CPU
+- Sockets :: 1
+- Cores :: 2
+- Enable NUMA :: check
+** Memory
+- Memory (MiB) :: choose what you want
+- Ballooning Device :: leave checked
+** Network
+- Bridge ::
+  When creating the VM, select the provisioning bridge (`vnet1306`). Once created, switch
+- Firewall :: uncheck, we will handle the firewall on the VM itself
+** Confirm
+* 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).
