[Bug 1432599] Re: Network-manager tries to manage virbr0, which it should not

 

Taking a cue from https://bugzilla.redhat.com/show_bug.cgi?id=1166199 I
worked around the issue by adding the following to my
/etc/NetworkManager/NetworkManager.conf

  [keyfile]
  unmanaged-devices=interface-name:virbr0

Yet I imagine that the real solution is something more general.

** Changed in: network-manager (Ubuntu)

Title:
  Network-manager tries to manage virbr0, which it should not

Status in network-manager package in Ubuntu:
  Confirmed
Status in network-manager package in Fedora:
  Unknown

Bug description:
  Since a recent upgrade in vivid, nm is trying to manage virbr0. This
  results in my main machine not getting a real IP address on eth0, and
  virtual machines not being able to use the network.
