Perhaps you can see a connection to QEMU like I do. The first step is to add a new connection. Click “File” and then “Add new connection”
As Hypervisor choose “LXC (Linux Containers)”
virt-manager show now an additional connection to LXC.
Creating a new container is very straight-forward. Just click a couple of times “Forward”. First give your container a name and select “Application container”
A shell is ok.
No need for plenty of RAM.
Ready to run.
This is now a Linux container 😉
