I only use VMs to run other operating systems on the server, for all other purposes I use containers. For example, some document servers insist on running on Windows while I insist on not running Windows. The solution is found in a VM which I fire up on demand when I need to access something from that server, accessed through (web)VNC. Once done I terminate the VM. All other services are run in containers, VMs and containers managed through Proxmox: qm start 600 to start ELSA, the VAG document server. Connect through VNC, find whatever was needed followed by qm shutdown 600 pct start 209 to start the Debian-stable build server, connect through SSH, build whatever is needed, package and copy the result out of the container followed by pct shutdown 209 pct start 208 starts the bookkeeping server, pct start 501 for the backup router, etc.
