I've installed a container using fedora-31-default_20191029_amd64.tar.xz on Proxmox Virtual Environment 6.1-7


After I've installed the container with the above template and do a dfm update then reboot, I loose network connectivity. Here's an example...

Code:

(performs dnf update and reboot)

If I update the network settings from within proxmox, the VM will update and work, however upon reboot it goes back to the above behavior.

Am I doing something wrong here? I'm relatively inexperienced with Proxmox but for the most part my experience has been rather straight forward.
