Open vSwitch (OvS) not working with Proxmox 7.1

I'm encountering issues with ovs on a brand new setup of a Proxmox 7.1 Server.

What I did:

1. Installed current Proxmox 7.1
2. Changed proxmox apt packages sources.list to "pve-no-subscription"
3. apt update
3. apt full-upgrade
4. apt install openvswitch-switch
5. Adatped the /etc/network/interfaces configuation as described in https://pve.proxmox.com/wiki/Open_vSwitch, a minimum configuration with one networkcard, and a bridge, and a vlan.
6. The same server hardware had before installed a proxmox 6.4 with working ovs. I also used my backuped /etc/network/interfaces configuration on the brand new installed proxmox 7.1 - without success.


After a reboot only the loopback/localhost interfaces are working (the only defined interfaces with "auto" and not using open vSwitch).

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

ovs-vsctl show replys with a empty json.

If I'm manually calling "ifup" for all the ovs defined interfaces (vmbr0, vlans and network devices) the network started to work, and the configuration is visible in "ovs-vsctl show".

Simply restarting the "networking" or ovs-switch deamon (without manually ifup the interfaces) is not solving the issue

I tried this with 3 different servers - all are showing the same behavior.

Looks for me like there is an issue in the ovs-startup-implementation in Debian? Any ideas how I can fix it, that the ovs networking is working on startup without manual commands (ifup)?

Thanks & BR
