Unable to connect to network via ethernet

Hi, I'm using NetworkManager as my dhcp client to connect to the internet, but after I installed virtualbox it doesn't work anymore..

In the logs it says something about ip-config-unavailable but I can't find a solution.
I have tried:
- A different cable (didn't work)
- A different os (worked)
- Connecting to wifi (worked)

Please help, thanks!

Re: Unable to connect to network via ethernet

No multiple network managing services, there've been reports that NMs internal dhcp is wonky, see eg. https://bbs.archlinux.org/viewtopic.php?id=231822
