Complete Guide to TrueNAS CORE Virtualisation Under Proxmox

Complete Guide: Step 4 - Install qemu guest agent

Follow this guide to install qemu guest agent for your TrueNAS VM. This is good to have as running the guest agent exposes certain functionalities to the Proxmox hypervisor.

If interested you can build the agent yourself here.Here is a list of all the features in the FreeBSD port. Unfortunately snapshot backups may be a problem as the FreeBSD port do not do suspend and fsfreeze functionalities. Do not rely on automated Proxmox backups, do a manual regular backups with the VM powered off once in a while just in case.

You will be doing the same with a regular TrueNAS machine anyway so this is no different. In fact backing up the entire OS is now easier in Proxmox, and is one of the reasons why I decided to use Proxmox hypervisor on top of TrueNAS core.

be careful in part 10

gpart add -a 4k -b 128 -t freebsd-zfs da4

must be

gpart add -a 4k -t freebsd-zfs da4

if you re specify the -b option with same number you will overwrite the first partition

Ryzen 5650 Pro CPU since it has ECC support and is an APU so no IPMI needed. AsRock Riptide X570 mobo since it supports ECC, lots of PCIE slots, and has excellent IOMMU grouping (and costs $120 new atm) NEMIX ECC ram DDR4 3200 4x32GB ~$350. 1 stick was bad and it only cost me time as warranty was fully honored. Note memtext x86 actually didnt detect it unless i tested 1 stick at a time though journalctl reported the bad stick accurately post mortem.
