Setting up a bridged network for KVM guests

This will work with either networkd or NetworkManager as a resolver. In fact, this is the only way to do bridged KVM (libvirtd) networking with NetworkManager.

If you're using NetworkManager (on a desktop or laptop, for example) on your KVM host, follow these instructions to set up a bridge interface.

Once you have the host bridge set up, proceed as follows:

1. Create a bridge network device inside KVM. Edit and save the below text as file host-bridge.xml:

Add a bridge interface to Ubuntu desktop using nmcli

Had to do this for some advanced networking with KVM, and couldn't figure out how to do it using the Nework Manager gui. Did find an article later that showed how to do it with nmtui, but it's so much easier to record what you did when using the cli.

Note: I now set net.ifnames=0 in grub for all my machines, to ensure my device names are "predictable" (so the first ethernet device will be "eth0" and not "ens1", "eno1 or anything else).

To see what everything looks like before starting:

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

Introduction

The following describes a way to remote unlock a server with natively-encrypted ZFS-on-root. It uses Dropbear SSH to start a SSH server in the initramfs listing on a specified port.

All server commands are executed as root on Debian 10. For Ubuntu, sudo su or adding sudo to all command should be sufficient.

Requirements

The following requires the recent ZoL 2.x, which adds support to Unlock encrypted root filesystem via SSH, making it merely a no-brainer to unlock the data set (besides setting up Dropbear).

Scenario:

• multiple USB devices plugged via hub to a host (Linux OS based),
• multiple services/programs interacting with TTY running on top (e.g. GPSd)

Problem:

At boot TTY are randomly assigned to devices causing depending services/programs instabilities. They could indeed fail to start because of different TTY configurations.

Solution:
