My Proxmox effort hit a wall today after a couple of days of smooth sailing. One of my Linux VMs fails to boot and goes into emergency mode. The file system seems OK, external disks are mounted and so on. But there is no active network interface active.
I found some log entries but they’re opaque to me. I’m hoping I’ll find some help on the Proxmox forum. It’s a bit scary getting this kind of error.
