In the following gist I'm going to guide you through the process of installing and booting an entire linux distribution with full desktop environment just like you would have with a classical VM, but with much better performance and much worse isolation :)

The reason why I did this was mainly because it's cool, but also to test new distros with decent graphics performance without actually booting them on my PC.

If you "try this at home" just keep in mind a container is not as secure as a VM, and some of the option we're going to explore will weaken container isolation from "a bit risky" to "totally unsafe" depending on what you choose.

Also, we're going to use systemd-nspawn for containers as it's probably the best fit for our use case and can also boot any linux partition without needing to prepare an apposite container image.

Less go!

We have Server machine, this computer with Headphones, and we have Client computer, this is remote PC with music =) On Server we should first open port for listening connections from Client :

# on ubuntu 
sudo ufw allow from <Client_IP> to any port 4656 proto tcp
# on fedora ( with firewalld ) 
sudo firewall-ctl --add-port 4656/tcp

note: port 4656 just for sample. you can use any port you want
than on Server, from current user add listening for connections

Fedora35 hibernation

This guide helps to configure the hibernation on a default Fedora35 (also worked fine in previous Fedora34) installation by using a swap file. The Fedora35 installation comes with btrfs as default filesystem. Also, it comes with a zram swap device:

$ swapon
NAME       TYPE      SIZE USED PRIO
/dev/zram0 partition   8G   0B  100

Getting Started

Installation
