After install an extra nvme ssd, lost connection to the pve box. (the netwok led do not blink).

ip link command will display the network link names similar to below:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp8s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master vmbr0 state UP mode DEFAULT group default qlen 1000
    link/ether a8:a1:59:07:39:22 brd ff:ff:ff:ff:ff:ff

The name is inconsistent with the iface name in/etc/network/interfaces.


create as file /etc/systemd/network/ with content:



so every reboot end up with the network name enp9s0 .
