Can't remove vmbr0 or access proxmox GUI

[shady.kozman]

Hello all,

i was having problems with my proxmox server as each time i reboot the server with 2 NIC eth0 keeps changing between the 2 physical ports. i followed this step as i saw it in another forum

/etc/default/grub
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
update-grub

so, after proxmox was up and running, now the interfaces was detected as
eth0, eth1, eth2 first 2 NICs are built-in interfaces on the physical server.

the problem is there's a vmbr0 bridge was created by me on eth0 but i can't find it on the GUI but i'm able to see it using ifconfig.

i tried to do ifconfig vmr0 down to remove it but once i did it i lost access to the GUI and even can't ping proxmox. i tried from the console to bring the interface up but still after the vmbr0 is up i still can't access or ping proxmox.

Any help please

Best regards

have a look in /etc/networking/interfaces as thats the configuration it all comes from

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto vmbr0
iface vmbr0 inet manual
        address <ip address in cidr>
        gateway <gateway ip>
        bridge-ports eth0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

if you want the IP on the eth0 interface

auto lo
iface lo inet loopback



auto eth0
iface eth0 inet manual
        address <ip address in cidr>
        gateway <gateway ip>
