I don't know what this issue is but it seems like after a clean install of Proxmox VE 6.4-6 has issues with ifupdown2 on OVH and I cannot seem to get the interfaces to work even after uninstall their cloud-init and resovconf packages. The SRV Networking (ifreload -a) issue with the invalid use of bridge attribute when creating multiple networking adapters has reared it's ugly head and I don't have an issue like this on my home proxmox server (but then again I have yet to update packages). I wonder if it's something that OVH has done to the Proxmox Template or me. I currently cannot use their KVM to do a ISO install because it crashes when I try to mount virtual media.
