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 PCIe 3.0 speeds for NVMe SSDs on Dell OptiPlex 3060

Out of the box, any M.2 NVMe SSDs connected to the Dell OptiPlex 3060 runs at PCIe Gen 2.0 speeds (Max 5 GT/s; 2 GB/s) so the speed tests look like this:

However, after this BIOS mod, the SSD can reach PCIe Gen 3.0 speeds (Max 8 GT/s; 3.9 GB/s) so the speed tests look like this:

Netgear Signed TLS Cert Private Key Disclosure

Overview

There are at least two valid, signed TLS certificates that are bundled with publicly available Netgear device firmware.

These certificates are trusted by browsers on all platforms, but will surely be added to revocation lists shortly.

The firmware images that contained these certificates along with their private keys were publicly available for download through Netgear's support website, without authentication; thus anyone in the world could have retrieved these keys.
