[SOLVED] Bridge vmbr0 exist and work, but GUI doesn't recognize it

[igorfk]

I have a vmbr0 configured and working but it's not recognized in the Web GUI and I cannot add or modify VMs in there because the GUI doesn't let me do anything since it cannot find it.

I can add or modify a VM manually editing configuration files in /etc/pve/qemu-server/ folder adding lines like net0: virtio=aa:bb:cc:dd:11:22,bridge=vmbr0,tag=123, but not in the Web GUI.

Other than that everything seems to be working fine.

The /etc/network/interfaces file

auto lo
iface lo inet loopback
iface eno1 inet manual
iface enp3s0 inet manual
auto vmbr0
iface vmbr0 inet static
    address 172.17.0.12/16
    gateway 172.17.0.254
    bridge-ports eno1
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094

auto DMZ
iface DMZ inet static
    address 192.168.17.12/24
    vlan-id 100
    vlan-raw-device vmbr0

auto WIFIADM
iface WIFIADM inet static
    address 172.10.0.12/16
    vlan-id 10
    vlan-raw-device vmbr0

PVE8, output of #uname -a

Linux pve 6.2.16-3-pve #1 SMP PREEMPT_DYNAMIC PVE 6.2.16-3 (2023-06-17T05:58Z) x86_64 GNU/Linux

How can I make the GUI recognize the configured vmbr0?

Are you using root or admin user ? If not , pve8 need acl permision on bridge now.

You're right I had to add the SDN.Allocate, SDN.Audit and SDN.Use privileges in the users group role, now I can properly edit VMs.

Thank you!
