VM and Docker failed to start after adding new vlan interfaces

[Coffee]

Hello, after adding new vlan interfaces on UnRaid, vm and docker services are failed to start. Does anyone know how to solve it?

 

VM: Libvirt Service failed to start.

Docker: Docker Service failed to start.

Don't see any logged docker start attempt, did you try rebooting?

Solved. After adding new vlan interfaces, the original br0 cannot get dhcp ip (expected), and I found out DNS is not configured and cannot resolve any ip address. After configured DNS and allowed internet access, docker and vm services are able to be started. Can't figure out why but it is solved.
