I messed my bridge config removing consistent interface naming

[joneco]

so first i will tell why i removed **consistent interface naming.**i am running a xeon server without onboard video. I bought a tela p100 video card and it doesnt have output video too. after some tries and disabling cms into the bios and adding above 4G decoding, things didnt worked too, but i was able to see that my sdd was beeing accessed and the access leds where blinking. i removed it put my desktop 6600xt card and saw that proxmox stoped beeing reached from browser, since i was with a gpu i entered into and saw that my network interface changed and i needed to modify from enp0s5 to enp0s6. after i remove the gpu and let the system go without gpu same thing, messed the network. so i decided to remove this bullshit that just make me upset, everytime i change a pci the ethernet adapter name changed, so it makes almost impossible for me to work without a video output and get things done

naming my adapter as eth0, the classic one solved everything and i was able to get it working with nvidia tesla and saw it in

root@promox:~# lspci | grep -e 3D
03:00.0 3D controller: NVIDIA Corporation GP100GL [Tesla P100 PCIe 16GB] (rev a1)

but i tried adjusting the bridge vmbr0 and all my containers and lxc cannot be reacheable and i cant ping between than,

my /etc/network/interfaces

(the commented part i tried too, so my proxmox ip is 192.168.31.2

other example my pihole is 192.168.31.100, and its setted into the lxc network section as was before

auto lo
iface lo inet loopback

auto eth0
#iface eth0 inet static
#       address 192.168.31.2/24
#       gateway 192.168.31.1
#       dns-domain prox.mox
#       dns-nameservers 192.168.31.100 8.8.8.8

auto vmbr0
iface vmbr0 inet static
        address 192.168.31.2/24
        bridge-ports eth0
        bridge-stp off
        bridge-fd 0

source /etc/network/interfaces.d/*

please guys help me all my vm and pxc now are not getting connected to my network. thanks
