Hi,
I am trying to enable the batman protocol on virtual machine. For this to happen there some manipulations that should be done on network device, e.g. create bridged interface and add existing interface to the bridge.
I am using systemd facility to run the service on startup which will do the job. However the job fails consistently because it does not find the devices of network card.
- I have set the dependency in the best way I could - doesn't help.
- I have tried to work with eth1 or eth2 (according to dmesg they are beinf renamed to ensXXX somwhere in the boot proccess) - doesn't help
Any ideas???
