#+title: Provisioning a Proxmox VM
#+author: Kevin Muller, Hans van Zijst & Nicolas Jeannerod
#+date: <2024-10-25 Fri>
* Fediversity Proxmox
- http://192.168.51.81:8006/.
- It is only accessible via Procolix's VPN; see with Kevin.
- You will need identifiers. Also see with Kevin. Select “Promox VE authentication server”.
- Ignore “You do not have a valid subscription” message.
* Basic terminology
- Node :: physical host
* 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 name for your machine.
- 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~.
- I have been using id ~XXX~ (starting from ~001~), name ~fediXXX~, ~95.215.187.XXX~ and
~2a00:51c0:13:1305::XXX~.
- Name servers should be ~95.215.185.6~ and ~95.215.185.7~.
- Check [[https://netbox.protagio.org][Netbox]] to see which addresses are free.
* Upload your ISO
- Go to Fediversity proxmox.
- In the left view, expand under the node that you want and click on “local”.
- Select “ISO Images”, then click “Upload”.
- Note: You can also download from URL.
- Note: You should click on “local” and not “local-zfs”.
* Creating the VM
- Click “Create VM” at the top right corner.
** General
- Node :: which node will host the VM; has to be the same
- VM ID :: Has to be unique, probably best to use the "xxxx" in "vm0xxxx" (yet to be decided)
- Name :: Usually "vm" + 5 digits, e.g. "vm02199"
- Resource pool :: Fediversity
** OS
- Use CD/DVD disc image file (iso) ::
- Storage :: local, means storage of the node.
- ISO image :: select the image previously uploaded
No need to touch anything else
** 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
- Tick “advanced” at the bottom.
- Disk size (GiB) :: 40 (depending on requirements)
- SSD emulation :: check (only visible if “Advanced” is checked)
- Discard :: check, so that blocks of removed data are cleared
** CPU
- Sockets :: 1 (depending on requirements)
- Cores :: 2 (depending on requirements)
- Enable NUMA :: check
** Memory
- Memory (MiB) :: choose what you want
- Ballooning Device :: leave checked (only visible if “Advanced” is checked)
** Network
- Bridge :: ~vnet1306~. This is the provisioning bridge; we will change it later.
- Firewall :: uncheck, we will handle the firewall on the VM itself
** Confirm
* Install and start the VM
- Start the VM a first time.
- Select the VM in the left panel. You might have to expand the node on which it is hosted.
- Select “Console” and start the VM.
- Install the VM as you would any other machine.
- [[Shutdown the VM]].
- After the VM has been installed:
- Select the VM again, then go to “Hardware”.
- Double click on the CD/DVD Drive line. Select “Do not use any media” and press OK.
- Double click on Network Device, and change the bridge to ~vnet1305~, the public bridge.
- Start the VM again.
* Remove the VM
- [[Shutdown the VM]].
- On the top right corner, click “More”, then “Remove”.
- Enter the ID of the machine.
- Check “Purge from job configurations”
- Check “Destroy unreferenced disks owned by guest”
- Click “Remove”.
* Move the VM to another 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).
* Shutdown the VM
- Find the VM in the left panel.
- At the top right corner appears a “Shutdown” button with a submenu.
- Clicking “Shutdown” sends a signal to shutdown the machine. This might not work if the machine is not listening for that signal.
- Brutal solution: in the submenu, select “Stop”.
- The checkbox “Overrule active shutdown tasks” means that the machine should be stopped even if a shutdown is currently ongoing. This is particularly important if you have tried to shut the machine down normally just before.
