Using VirtioFS backed by CephFS for bind mounts

This is currently a work-in-progress documentation - rough notes for me, maybe missing a lot or wrong

The idea is to replace GlusterFS running inside the VM with storage on my cephfs cluster. This is my proxmox cluster and it runs both the storage and is the hypervisor for my docker VMs.

Other possible approaches:

ceph fuse clien in VM to mount cephFS or CephRBD over IP
use of ceph docker volume plugin (no useable version of this yet exists but it is being worked on)

Assumptions:

Upgrade Python 3.10 to 3.11 on Ubuntu 22.04

Check python version use python and python3

The first comman will Not show version info.

The second one show 3.10 as version as it is provided by ubuntu as default

python --version
python3 --version

Add additional repository to download python 3.11

Mount Volumes into Proxmox VMs with Virtio-fs

Part of collection: Hyper-converged Homelab with Proxmox

15-04-2025: Seems Proxmox added this now to the GUI; see Using VirtioFS backed by CephFS for bind mounts how to use it.

Virtio-fs is a shared file system that lets virtual machines access a directory tree on the host. Unlike existing approaches, it is designed to offer local file system semantics and performance. The new virtiofsd-rs Rust daemon Proxmox 8 uses, is receiving the most attention for new feature development.

Performance is very good (while testing, almost the same as on the Proxmox host)

Enable & Using vGPU Passthrough

This gist is almost entirely not unlike Derek Seaman's awesome blog:

Proxmox VE 8: Windows 11 vGPU (VT-d) Passthrough with Intel Alder Lake

As such please refer to that for pictures, here i will capture the command lines I used as i sequence the commands a little differently so it makes more logic to me.

This gists assumes you are not running ZFS and are not passing any other PCIE devices (as both of these can require addtional steps - see Derek's blog for more info)

This gist assumes you are not running proxmox in UEFI Secure boot - if you are please refer entirely to dereks blog.
