For reference: https://bugzilla.proxmox.com/show_bug.cgi?id=6314This started to happen again with this new VM that I have. I figured out that this was happening because I added it to the HA group and it was set to started. So when it would see it shut down, HA services in Proxmox would restart it. The best thing to do here is to set it to either Ignored or just not add it to the HA configuration.
