Installing Proxmov VE 5.4 ont Qemu and removing the "no valid subscription" popup

Описание: In this recording I am installing Proxmox VE 5.4 onto a Qemu virtual machine, then removing the annoying subscription banner, since this is just a test setup. I am then also installing a Centos 6 container and a Centos 7 virtual machine, so that they can be used in the setup of X2Go, which will be in a later recording. Below are some of the commands that I used during the installation.
In this video I am installing Proxmox VE 5.4 into a Qemu virtual machine, so that I can use a web interface to manage some virtual machines that I will be setting up. I am also trying to remove the register nag dialog that appears when you login, but I did not manage to succeede in this video. I am also showing how distribution iso files can be uploaded, so that they can be selected when a virtual machine is created.
