I am installing Flatcar in a Proxmox VM. I have already several VMs working under the `vmbr0` bridge.
I disabled the Firewall while defining the VM in Proxmox.
Everything goes fine during the install from the Flatcar Production ISO image.
But when I `ip a` , only IPV6 is available under the `eth0` interface, not IPV4, which I need to connect to my local network and upload the Ignition file.
I also double-checked using the Flatcar ISO image I had used previously to create another Flatcar CT. The IPv4 is also not available.
So I guess there is something in my Proxmox deployment which is wrong.
