Proxmox

Quid

Proxmox Virtual Environment (Proxmox VE or PVE) is a Virtualization platform designed for the provisioning of HCI (hyper-converged infrastructure: virtualized computing (a hypervisor) + virtualized storage + virtualized networking in a unified software-defined system).

Proxmox allows deployment and management of virtual machines (with KVM) and containers (with LXC). It is based on a modified Debian LTS kernel. It includes a web-based management interface.

Setup

UI Settings

Network:

Datacenters > “proxmox” > System > Network > Create/Edit interface as needed (e.g 192.168.137.11/24)

Activate and do updates:

Datacenters > “proxmox” > Updates > Repos:
- Add http://download.proxmox.com/debian/pve
- Disable the entreprise ones
In Updates: “Refresh” then “Upgrade”

Once NAS is available:

Mount an SMB share from NAS
Schedule backups (Datacenter > Backup > Add) with email reports

TODO: Notification System configuration

Terminal settings

Do some limited config for the root account, such as installing a couple of programs, setting up aliases and strengthening sshd. See Linux Systems Setup.

Wifi (if needed)

apt update && apt install wpasupplicant vim
systemctl disable wpa_supplicant
wpa_passphrase SSIDNAME PASSWORD >> /etc/wpa_supplicant/wpa_supplicant.conf

IOMMU

Should be enabled by default for AMD processors.

Useful commands for dealing with (PCIe) disks:

ls -l /sys/block/nvme*/device # /sys/block/nvme1n1/device
 
lsblk -o NAME,FSTYPE,MOUNTPOINT,SIZE,MODEL
# nvme1n1                                             465.8G WD Blue SN580 500GB
# └─nvme1n1p3                  LVM2_member            464.8G
#   ├─pve-root                 ext4        /             96G

Notes on cloning a VM

These things need to be changed on the new VM!

Change hostname in: /etc/hostname and /etc/hosts

Reset machine ID:

rm -f /etc/machine-id /var/lib/dbus/machine-id
dbus-uuidgen --ensure=/etc/machine-id
dbus-uuidgen --ensure

Regenerate ssh keys:

regen ssh keys
sudo rm /etc/ssh/ssh_host_*
sudo dpkg-reconfigure openssh-server
