That the IP address is configured on the vmbr0 interface is normal and the basic default after a fresh installation. You can change that later if you want to place the MGMT IP somewhere else. The vmbr0 interface is needed as the "virtual switch" to which the guests will be connected to. The vmbr0 is using the physical interface as bridge port. Check out the /etc/network/interfaces file for more details.
Regarding the network not working; do you have more than one NIC in that system? If so, it is likely that the installer selected the NIC that is currently not connected. You could try to just plug in the cable to the other NIC or change the /etc/network/interfaces file accordingly so that the vmbr0 will use that other NIC. Then either reboot or run `ifreload -a` to apply the network config. If that is not the case, and there is only one NIC in the system, try to run `ip l s <NIC> up` and also check your kernel logs / dmesg for any messages regarding the network that might give us more information why the NICs are not up.

Hello, All - I'm a new user of Proxmox, having just installed VE 7.1-2 for about the 5th time trying to resolve the following issue: After a successful install, I login to my host as root. I cannot ping in or out of the host; "ip address" & "ip link" commands show that the eno1 and vmbr0 interfaces are "UP", but their states are "DOWN". Static IP address is shown on vmbr0 interface only - I would have imagined that it would have been set to the eno1 interface instead during the install but, again, this is my first exposure to this product. Connection to my switch show no activity from the host. Ethernet cable has been verified to work on another host. Any ideas?? Thanks, and best wishes to all in 2022! Cheers!
