Description

Hi,

I created a virtual network in docker:

docker network create \ -o parent=virbr2-lab \ -o com.docker.network.bridge.enable_icc=false \ --driver macvlan \ --subnet 192.168.2.0/24 \ --gateway 192.168.2.10 \ docker-lab2

and i connected a container (linuxserver/ubooquity) to this network and it's work but after a restart if i start the container i have this message:

docker container start ubooquity
Error response from daemon: failed to create endpoint ubooquity on network docker-lab2: network id "05669dcbecbb4298cca6f59517b6adad1a66081a7c28658213a37dc710392650" not found
Error: failed to start containers: ubooquity

Research direction

Reproduce the reported docker network create command, container connection, server restart, and subsequent start failure. Start by inspecting how the Docker daemon restores macvlan networks and container endpoints after restart. Done means identifying why the existing docker-lab2 network ID is unavailable and adding a verified fix or regression test.
