It seems the 15.04 version of network manager (0.9.10) is now quite out- of-date (!).
https://wiki.gnome.org/Projects/NetworkManager/ From https://download.gnome.org/sources/NetworkManager/1.0/NetworkManager-1.0.4.news * The management of devices can now be controlled with udev rules. The veth devices as well as the virtual Ethernet devices of various virtualization tools (VMWare, VirtualBox, Parallels Workstation) are now ignored by default. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1485558 Title: NetworkManager breaks vboxnet* connections since 15.04, worked in 14.04 and 14.10, nm-applet fills with irrelevant entries. 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.
