I have a Ubuntu server instance running on a virtual box machine which is running on a Windows 10 machine. I converted the VM to physical and put it in a new machine and booted it up. It boots fine but there is no functioning network.
To make the conversion I booted into clonezilla in the VM and cloned the virtual drive to an external hard drive. Then on the new machine I did the same to clone the external drive to the internal drive on the new machine. It boots fine but there is no internet connection. When doing ifconfig the adapter is docker0.
I've tried a fresh install on a different drive on the same machine and the networking worked good. The adapter there is eno1 and has a different mac address than the docker0 adapter on the cloned install.
I've done some googling and haven't been able to find anything that would seemingly fix this and I'm at a loss at how to get the networking functional again.
Edit to add requested info: Ubuntu version is server 18.04.
See attached pic for id addr output:
Edit 2: Picture of hangup during boot:
ip addr
on the bare-metal server...and clearly explain exactly which release of Ubuntu you are running. Virtual interfaces are NOT the same as real interfaces, so "docker0" not working seems like expected behavior.
