No IP after we reboot router / modem

Hello, community

So, we have a bunch of USB dongles ( Huawei e3372 modems ) connected to a ubuntu host server ( ubuntu 16 ) running LXC containers.

Each dongle is connected to a specific container running ubuntu. ( using macvlan nic type )

The problem we are facing is when we disconnect the dongle, we can’t see the attached interface. ( NO Internet in the container. ) it appears again when we restart the container.

Any possible solution? so the dongle gets attached without restarting the container?

Hi!

How do you get the USB dongles passed to each container? What kind of device?
