Status in network-manager package in Ubuntu: Confirmed Bug description: On an Asus laptop running a freshly installed Ubuntu 15.04 64-bit, nm- applet shows that NetworkManager wants to manage vboxnet0 and vboxnet1. These are created by virtualbox which runs some guest OS inside a VM. On previous Ubuntu releases, network-manager did not try to manage them and there was no problem. # Observed behavior * nm-applet shows spinning animation for a long time, while it is not relevant. Clicking on "disconnect" in the menu unconfigures the interface which breaks it. * after suspend-resume of the host, vboxnet* lose their correct configurations. vboxnet0 (a host-only interface where virtualbox runs a private dhcp server) gets a different IP address. Looks like https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1460750 but does not feel like a bug in virtualbox. # Expected behavior * Just like in 14.04 and 14.10, these interfaces are just ignored by network-manager and they just work. # Additional information * After reading http://superuser.com/questions/9720/disabling- networkmanager-for-a-specific-interface tried to add these lines to /etc/network/interfaces. Even after restarting network-manager, it has no effect. iface vboxnet0 inet manual iface vboxnet1 inet manual So, reverted the change. * Tried from https://blogs.gnome.org/dcbw/2015/02/16/networkmanager- for-administrators-part-1/ to add in /etc/NetworkManager/conf.d/ a file 50-virtualbox.conf containing the following lines. Even after restarting network-manager, it is ignored. [keyfile] unmanaged-devices=vboxnet0,vboxnet1 * This is not eactly like https://www.virtualbox.org/ticket/13873, I'm not using Vagrant. * Booting to 14.04 or 14.10 (that have been kept intact on the same machine) things just work as expected. * /usr/share/doc/network-manager/NEWS.gz states that "'veth' interfaces are now unmanaged by default to cooperate better with external tools". Should vboxnet* be treated the same ? * This seems on the topic but unclear to me: https://bugzilla.gnome.org/show_bug.cgi?id=731014 Thank you for your attention.
