This post will show how to use the web browser interface to create a container in a Proxmox host running under Virtualbox. In Virtualbox, the network failed to initialize with the default DNS server. Using a publicly available DNS server (such as 8.8.8.8) avoided this.

First, log in to the browser based gui.

To download a container template, select “local” from the menu on the left, “CT Templates” from the next menu, and click on the “Templates” button (shown highlighted in blue outline):

Click on the “Create CT” button. Up pops a “Create LXC Container” wizard. Choose a password.

Use the container template downloaded earlier.

For DNS servers, choose 8.8.8.8 (or some other publicly available server).
