vagrant creates networks like:
vboxnet1
[ for some reason it started at 0, now it is 1 for me ]
to avoid sleep interferences:
- put the following in /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
[keyfile]
unmanaged-devices=interface-name:vboxnet0
unmanaged-devices=interface-name:vboxnet1
