Install any OS on Hetzner VDS | Proxmox with ZFS on Hetzner VDS.md

Step 1. Starting the Rescue System - Linux 64bit

Activating the Rescue System

To start a server in the Rescue System, it needs to be activated in the Robot.

Under "Main Functions; Server" select the desired server and then open the tab "Rescue". Here the desired variant can be activated.

The password that was given to you when you activated the Rescue System can now be used to login as "root" via SSH. Restarting the Server

To load the Rescue System, the server must be restarted.

If you no longer have access to the server, you can use the reset function in the Robot. You will find this under the "Reset" tab of the desired server.

Please note that the activation of the Rescue System is only valid for one boot. If you want to boot your server to the Rescue System again, you will have to activate it in the Hetzner Robot again. If you do not reboot your server within 60 minutes after the activation, the scheduled boot of the Rescue System will automatically become inactive. If the server is restarted later, the system will boot from the internal drive(s).

Step 2. Connect to Rescue System vis SSH

Step 3. Gather Network Inforation

We need to find real interface name, IP address, mask and gateway

  • Real Interface Name
udevadm info -e | grep -A 20 ^P.*eth0 | grep ID_NET_NAME_PATH

Example of output: E: ID_NET_NAME_PATH=enp35s0 My interface is enp35s0

  • In some cases, you will need to check the kernel logs to find real name:
cat /var/log/kernel | grep renamed
  • IP Address/Netmask & Gateway
ip -c a
ip route

Step 4. Start QEMU Emulator for installation the OS to disks

wget 'http://download.proxmox.com/iso/proxmox-ve_6.2-1.iso' -O proxmox-ve_6.0-1.iso

lsblk
printf "change vnc password\n%s\n" MYPASSWORD | qemu-system-x86_64 -enable-kvm -m 10240 -hda /dev/nvme0n1 -hdb /dev/nvme1n1 -cdrom proxmox-ve_6.0-1.iso -boot d -vnc :0,password -monitor stdio

MYPASSWORD is a password for VNC connection

Step 5. Connect via VNC to your server port 5900, and follow the installation procedure

Use serverip:0 and your password
During install properly configure the Network with previously found information.

  • Turn off qemu at install finish
  • Then run qemu without cdrom:
printf "change vnc password\n%s\n" MYPASSWORD | qemu-system-x86_64 -enable-kvm -m 10240 -hda /dev/nvme0n1 -hdb /dev/nvme1n1 -vnc :0,password -monitor stdio

Qemu will boot to installed Proxmox.

Edit network interfaces by changing interface name:

nano /etc/network/interfaces

auto lo
iface lo inet loopback

iface enp35s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 117.xxx.xxx.108
    netmask 255.255.255.192
    gateway 117.yyy.yyy.65
    bridge_ports enp35s0
    bridge_stp off
    bridge_fd 0
  • Poweroff Proxmox, close qemu & and restart dedicated server

Step 6. Connect to Web interface
