Multiple NICs

[neohidra]

I have a node with multiple NICs. Proxmox runs on a vmbr0 Bridge with static Ip address.
I tried to move a VM to a separate NIC but without success. Here is what i have done:

1. created a new bridge to a different NIC without IP address (vmbr1)
2. removed the NIC from the VM
3. created a new NIC bridged to vmbr1
4. now the VM wont start because of

   bridge 'vmbr1' does not exist

5. if its bridged to vmbr0 it will work just fine

The newly created bridges are shown as not not active (in Nods network tab). Why is that so and how can i activate the new bridge?

It turns out the Ethernet cable was faulty
