darts

An opaque third-party/customer VM. Declared in colony's my.vms.instances but not a NixOS system: this repo knows nothing about what runs inside it and doesn't manage it.

• Source (host-side only): the darts instance in nixos/boxes/colony/vms/default.nix and the 90-vm-darts network in nixos/boxes/colony/default.nix
• Host: VM on colony
• nixpkgs: not applicable (unmanaged guest; host-side definition uses colony's mine-stable)

Role

• Customer/dedicated VM, left alone beyond hosting and connectivity.
• A thin-provisioned root LV on the NVMe pool, plus darts-media (RAID 5 across the four HDDs) and darts-ext (linear storage on the 18 TB HDD) in the main VG. See colony's storage layout.

Network assignments

This guest is not a NixOS system, so its host-routed addresses are not rows in the generated network assignments table.

• Same customer-VM pattern as mail: dedicated unbridged TAP (vm-darts), point-to-point address (custRouting.darts-vm) on the host side, link-routed public /32 94.142.242.255, and the IPv6 /64 2a0e:97c0:4d2:2001::/64 with RAs.
• DNS: darts-cust.ams1.int.nul.ie. Like the other customer prefixes, its inbound traffic is accepted by estuary without per-port filtering and forwarded on by colony.

Notable config files

• nixos/boxes/colony/vms/default.nix — VM definition.
• nixos/boxes/colony/default.nix — host-side network and routing.
