			Lupine 4 hadde lenge bare 8 GiB med RAM. Dette førte til at når den påtok seg CI/CD arbeid ville den bruke flere timer før den timet ut. [[User:vegardbm]] irriterte seg grundig over å måtte gamble med CI/CD og [https://git.pvv.ntnu.no/Drift/pvv-nixos-config/pulls/130 skrudde den av]. Rundt en måned senere ble det funnet en ekstra pinne med 8 GiB DDR4 RAM som da ble installert på Lupine 4 slik at den kunne gjøre jobben sin.

NTNU hoster [https://www.openstack.org OpenStack], du kan finne mer informasjon om det [https://www.ntnu.no/wiki/spaces/skyhigh/pages/93261214/Openstack+at+NTNU her]. PVV har fått utdelt følgende ressurser: 23 instanser, 46 vCPUs, 66GB RAM, 25 volum, 10 volum snapshots, 5.4TB volumlagring, 16 flytende ip adresser, 200 security groups, 2000 security group rules, 25 nettverk, 250 ports, 10 rutere på https://stack.it.ntnu.no.

Her kjører ulike VMer slik som [[Maskiner/gluttony]].

[[File:OpenStack ressursoversikt.png|thumb|alt=Oversikt over ressurser som er begrenset på OpenStack.|Her kan du se en oversikt over ressurser som er begrenset på OpenStack.]]For den det kunne gjelde så har [https://www.ntnu.no/wiki/spaces/skyhigh/pages/112272779/IPv6+tenant+networks#IPv6tenantnetworks-AllowincomingSSH denne kommandoen] i dokumentasjonen til NTNU brukt et flagg som ikke lenger finnes. Du må antakeligvis bare erstatte --src-ip med --remote-ip.

= Instance Setup =
Når du setter opp en instance/server henter den metadata fra http://169.254.169.254 som du kan lese mer om [https://docs.cloud-init.io/en/latest/reference/datasources/openstack.html#metadata-urls her]. Dette blir brukt av cloud-init som sørger for ting slik som å sende over din offentlige sshnøkkel.
For å sette opp en ny server kan du skrive en kommando slik som dette:
openstack server create servername --flavor sx3.16c16r --boot-from-volume 256 --network pvv-trd1 --key-name keyname --image dfc7f8c4-0747-41a7-a52e-1bdf615a296c --security-group default
Her må du sørge for å sette navnet, at verdien etter image flagget er UUIDen til bildet du ønsker, sørge for at du velger passende med plass etter boot-from-volume flagget som er spesifisert i GiB, riktig navn på nøkkel, riktig flavor altså mengden ram og antall vcores og passende security group.

The first step in setting up a new NixOS host is well, installing NixOS. This however varies based upon whether or not you have physical access to the device, and if it already has an OS installed already. For this guide we will assume you already have a system with Nix installed. If you do not have a system with Nix, you can use one of PVV machines already with NixOS, or you can install Nix or NixOS by following the instructions [https://nixos.org/download/ here].

			= Installing NixOS =
			== Installing on a device with physical and without an installed OS ==
			You first want to create a bootable USB with a NixOS image on it. This is described [https://nixos.wiki/wiki/NixOS_Installation_Guide#Making_the_installation_media here]. But in short you want to download the ISO and copy it over to the USB device:
			cp nixos.iso /dev/sdX
			After booting into the USB you can now follow the instructions defined [https://github.com/nix-community/nixos-anywhere/blob/main/docs/howtos/no-os.md here].
			Note that because nixos-anywhere uses SSH, you can choose to run the nixos-anywhere command from the system with the live ISO or your own machine connected to the same local network.

			== Installing on device with phyiscal access but with an OS ==
			You only need to make sure you can access the device with SSH.

			== Installing on a remote device ==
			If you are setting up a device on something like [[OpenStack]], you just need to set up an OS with SSH.

			= nixos-anywhere setup =
			You first want to create your flake and other necessary nix files for nixos-anywhere. You can follow the instructions provided [https://github.com/nix-community/nixos-anywhere/blob/main/docs/quickstart.md here].

			= Creating a new host in pvv-nixos-config =
			First clone the repo:
			git clone https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git && cd pvv-nixos-config
			You can now create a directory under hosts with the hostname of the device. In this directory you want to place your disko config and your hardware-config. You can generate a hardware-config with this command:
			nixos-generate-config --show-hardware-config > hardware-config.nix
			You then want to create a configuration.nix file. You should look at other hosts as examples for this such as [[Maskiner/gluttony]]. If you use gluttony as a starting point you should consider using systemd-boot instead if you are not on OpenStack, and removing things related to emulating other architectures. You should also make sure that the correct ethernet interface was configured. You can see which you have available by running:
			ip a
			The ethernet interface should start with en, such as ens3.
			Next you want to set values such as ip address in values.nix.
			The last step is to start using the config you have just created, but use the hostname you have selected:
			sudo nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --flake .#myhostname --upgrade
