Here's a Systemd service that will automatically disable the "No valid subscription" nagware dialog in Proxmox VE. I got the snippet to disable the dialog from this article from John's Computer Services.

Save the systemd service to /etc/systemd/system/proxmox-patcher.service
Save the shell script to /root/proxmox-patcher.sh
Run chmod +x /root/proxmox-patcher.sh as root
Run systemctl enable proxmox-patcher.service as root
Restart

Attaching a directory from a host to a libvirtd guest VM

NOTE: These instructions aren't comprehensive! This just covers the main roadblocks every time I need to re-do this process...

(For context, I'm using a Debian 10 host and a Debian 10 guest)

1. Create the directory and update the permissions so `libvirtd-qemu` has access:

host $ mkdir vmshared

Recently, I had an issue where I had no loopback device in Linux Mint 18.2 MATE, which occurred after upgrading from 18.1 MATE.

Diagnosis

ping localhost fails, nc -v -l -p 1234 followed by nc localhost 1234 does not connect, etc. Running ifconfig does not show a loopback device present.

Running sudo service network-manager restart and sudo service networking restart doesn't fix the issue, nor does restarting.

The only clue shows up when inspecting /var/log/syslog:
