I am using a motherboard with dual NICs and successfully setup linux bridges for eth0 and eth1 as vmbr0 and vmbr1 on Promox 4. Everything ran smoothly and the ifconfig shows all eth0, eth1, vmbr0, and vmbr1 all working and properly configured:

After that I attempted to create a "Network Bond" and deleted vmbr0 and vmbr1 then rebooted without fully realizing Proxmox needs those bridges for the NICs to connect to the outside world. I know I am a total idiot so my apologies in advance for all this. Upon rebooting I could not access the web interface or the machine remotely.

I went through the forums and the wiki (https://pve.proxmox.com/wiki/Network_Configuration) to try to figure out how to configure the /etc/interfaces file properly. I manually created an "interfaces.new" file and configured vmbr0 and then rebooted for those changes to take effect in an attempt to be able to connect to the webgui.

Upon rebooting, I ran "ifconfig" and "ip link show" and the vmbr0 I created was not listed. Also, eth0 and eth1 look to be in the "Down" state.

Can someone please advise what I need to manually modify in the "interfaces.new" file for vmbr0 so I can access the WebGUI again? Am I missing a step before rebooting for the changes I made to the "interfaces.new" file to take hold?Many thanks in advance!
 
your syntax is wrong:

its not:

Code:
address: x.x.x.x
netmask: y.y.y.y

but

Code:
address x.x.x.x
netmask y.y.y.y

(notice the missing ':')
