GNS3 VM First Launch - The Non-Existing `vboxnet0` Interface
The first time I tried to run the GNS3 VM for VirtualBox, I had an error about some vboxnet0 interface that couldn’t be found. I wandered in VBox GUI, clicked here and there without really understanding what I was doing. Then, in the network settings of the Host Only interface I stumbled across a field named Name; I clicked more, thinking I could edit it and giving it the required name. But this field couldn’t be edited right away. Damn! Should I sudo the VBox to show it who’s the click boss? I didn’t. Instead, I asked to my favorite search engine. And after a few more click, I got my answer: the interface had to be created first (perhaps with some sudo, I don’t remember, I was upset):
1
vboxmanage hostonlyif create
Then I could launch the VM and continue to explore more things I don’t understand.
