Unable to restart pve-manager service and OVS bridge not appearing in Proxmox Web UI

Hello everyone,

I am currently facing an issue where my Open vSwitch (OVS) bridge (ovsbr0) appears as "Unknown" in the Proxmox Web UI. Additionally, I am unable to restart the pve-manager service manually.

### Proxmox Version:
- Proxmox 8.x

### What I have done so far:
1. Converted from Linux Bridge to OVS:
- Configured /etc/network/interfaces with OVS settings.
- Restarted networking services.

2. Encountered issues:
- eno1 and ovsbr0 were initially down.
- Had to manually bring them up using `ifconfig`.

3. Manual Addition of Ports:
- Had to manually add ports via `ovs-vsctl add-port` upon every reboot.

4. Attempted to restart pve-manager service:
- Fails with error: "Operation refused, unit pve-guests.service may be requested by dependency only."

5. Ovs bridge cannot be configured for vm instance

### Workarounds:
- Manually adding the ports and bringing them up seems to make things work temporarily.
- Used `auto eno1` and `iface eno1 inet manual` with `ovs_bridge ovsbr0` and `ovs_type OVSPort` in the /etc/network/interfaces file to solve the problem of ports not being added automatically on reboot.

### Questions:
1. How can I make the Proxmox UI recognize the OVS bridge?
2. Is there a way to permanently add ports so that they survive reboots?
3. Has anyone encountered the issue with restarting the pve-manager service, and if so, is there a solution?

Any help would be greatly appreciated!

Thank you.
