I have two NIC RTL r8125 and x710-da4. SR-IOV is working fine and set up at boot.
When I put nic0 r8125 to vmbr0 everything is working.
When I put enp133s0f3v3 (x710 sr-iov) to vmbr0 I have only connectivity to network from proxmox. In VM or containers no network, I can't ping server.

Code: 
face enp133s0f3v2 inet manual

iface enp133s0f3v3 inet manual

iface wlp131s0 inet manual

iface enp133s0f2v0 inet manual

iface enp133s0f2v1 inet manual

iface enp133s0f2v2 inet manual

iface enp133s0f2v3 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.56/24
        gateway 192.168.1.1
        bridge-ports nic0
        bridge-stp off
        bridge-fd 0

Not sure of your exact setup, but what happens if you bridge it to vmbr1 (new bridge port) & then connect VM/CT to vmbr1.

VM are now connected to vmbr1
Code: 
iface vmbr0 inet manual
        bridge-ports nic0
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address 192.168.1.56/24
        gateway 192.168.1.1
        bridge-ports enp133s0f3v0
        bridge-stp off
        bridge-fd 0

source /etc/network/interfaces.d/*
- proxmox ok/VM failed

Code: 
auto vmbr0
iface vmbr0 inet static
        address 192.168.1.56/24
        gateway 192.168.1.1
        bridge-ports nic0
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address 192.168.1.57/24
        bridge-ports enp133s0f3np3
        bridge-stp off
        bridge-fd 0

source /etc/network/interfaces.d/*
- proxmox OK/ VM ok

What just happen? Why on vmbr1 it's fine? How to repair it.
