# koyomi
## Hardware
System from [Hetzner Online Serverbörse](https://www.hetzner.com/sb).
- Motherboard: FUJITSU D3401-H1
- CPU: Intel Core i7-6700
- RAM: 4×16GB Samsung [M378A2K43CB1-CRC](https://semiconductor.samsung.com/dram/module/udimm/m378a2k43cb1-crc/)/[M378A2K43BB1-CPB](https://semiconductor.samsung.com/dram/module/udimm/m378a2k43bb1-cpb/) (DDR4 2400/2133MHz)
- SSD: 2×512GB M.2 NVMe SAMSUNG MZVLB512HAJQ-00000
## Setup
As it is a physical server (not a VM) in a remote location,
extra care must be taken when installing.
Fortunately, Hetzner provides an automated way to reset the server (by sending Ctrl+Alt+Del or force resetting)
and a rescue system that can be activated before a reboot.
Additionally, there is also a *vKVM* rescue system,
that boots a hypervisor from the network and runs a VM which boots from the physical disks.
The rescue system can be used to start a kexec installer generated by [nixos-generators](https://github.com/nix-community/nixos-generators).
Ideally, everything goes well and the next reboot works,
but in the case it does not, the vKVM rescue system can be used for debugging.
## Purpose
Hypervisor. Exact scope is to be determined.
## Name
Araragi Koyomi is a student from the *Monogatari Series*.
