Proxmox

Hey there! Just wanted to let you know that these are my personal notes and not necessarily a tutorial. Some things may not work in your environment due to differences in networks and subnets. If you see a domain name, it probably refers to an IP address of a machine that I have set up for myself.

If you have any questions or need help, don't hesitate to reach out. I'm here to help.

Network: 10.6.6.1/24 - DMZ
VLAN ID: 600
IP: 10.6.6.5
WebUI: https://10.6.6.5:8006

Installation

The Proxmox bare-metal ISO installer doesn’t work for me. Instead, I have to install it over the top of Debian.

Debian 11.5 - Bullseye

Setup the installation USB

Find the USB disk that will be used for the install.

sudo fdisk -l

Copy the ISO to the USB disk

Replace /dev/sdX with the USB disk found above.

sudo dd if=~/Downloads/debian-11.5.0-amd64-netinst.iso of=/dev/sdX status=progress

Install

Insert the USB disk into the machine and boot from it. Follow the prompts to provision and install on the desired disk or disks.

Network

Make the following change to /etc/hosts

- 127.0.1.1 debian.local_domain debian
+ 10.6.6.5 inf-thor.jasonbrennan.com inf-thor

Proxmox 7.3

Add Proxmox repo to APT

echo "deb [arch=amd64] [http://download.proxmox.com/debian/pve](http://download.proxmox.com/debian/pve) bullseye pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list;

Add Proxmox Repo key

sudo wget [https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg](https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg) -O /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg;

Verify the key

sha512sum /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg;
# 7fb03ec8a1675723d2853b84aa4fdb49a46a3bb72b9951361488bfd19b29aab0a789a4f8c7406e71a69aabbc727c936d3549731c4659ffa1a08f44db8fdcebfa  /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg;

Update apt cache and packages

sudo apt update && sudo apt full-upgrade;

Install Proxmox kernel

sudo apt isntall pve-kernel-5.15 && systemctl reboot;

Install Proxmox packages

sudo apt install proxmox-ve postfix open-iscsi;

Choose local only for mail server

Remove Debian Kernel

sudo apt remove linux-image-amd64 'linux-image-5.10*';

Update Grub

Add /usr/sbin to $PATH:
Adding the following helps to ensure that the /usr/sbin is added to $PATH for su just like it’s added for su - There are also other solutions in this bug report

su;
echo 'export PATH=$PATH:/usr/sbin' > /bin/bash && source /root/.bashrc;
update-grub && exit;

Remove the os-prober

sudo apt remove os-prober

Network

Add a bridged network that allows virtual machines to access the LAN.

sudo vim /etc/network/interfaces

Proxmox set to a static IP using DHCP.

auto enp5s0
iface enp5s0 inet dhcp

auto vmbr0
iface vmbr0 inet static
	address 10.6.6.5/24
	gateway 10.6.6.1
	bridge-ports enp5s0
	bridge-stp off
	bridge-fd 0
	bridge-vlan-aware yes
	bridge-vids 2-4094

Restart the network

sudo systemctl restart networking
