While trying to install proxmox on my system the gui did not work so i had to install debian13 first then proxmox - all was going well until I started looking at the networking details and I am seeing no vambr0. I have seen multiple questions about this and it is just kind of glanced over. How do I create the vmbr0 on my proxmox system?
 
This is that section of my /etc/network/interfaces. You need to use "nano" or "vi" to edit yours to look similar. Replace the "bridge-ports" line with whatever the name of your Ethernet device is (mine being enp191s0) and the address and gateway with ones appropriate to your network.

Code:
iface enp191S0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.9/24
        gateway 192.168.1.1
        bridge-ports enp191s0
        bridge-stp off
        bridge-fd 0
 
What an idiot!! I can't believe that I looked at that all day and did not realize that it was just an edit not an installation!! Thank you so much
