Can't get interfaces up

[oguruma]

Motherboard with 4 on-board NICs. Proxmox has named them rename rename1 rename2 rename3 and rename4 (which is annoying, but not the topic of this post).

Rename2 is bridged to vmbr0. I want to keep using that for management.

I want to give a VM its own NIC. I created vmbr1 and added rename4 as a port.

I created the VM and added vmbr1 as its NIC.

I get network unreachable on that VM, and I see no blinkies on the server's NIC or the switch port its connected to. Proxmox network configuration below.

Cable is fine, tried rebooting several times....

Any ideas?

auto lo
iface lo inet loopback

auto rename2
iface rename2 inet manual

auto rename3
iface rename3 inet manual

auto rename4
iface rename4 inet manual

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.4.1/16
        gateway 192.168.0.1

auto rename
iface rename inet manual

auto vmbr1
iface vmbr1 inet static
        address 192.168.5.1/16
        bridge-ports rename4
        bridge-stp off
        bridge-fd 0

that might be the core of the issue ..

check the journal since booting (especially for messages from the NIC driver.
