Description of problem: When running in qemu/kvm virtual machine, constant failures related to modemmanager. It also correlates (possibly causes) to avahi no longer working (unable to resolve mdns hostnames right when the modemmanager error occurs) even though it continues to run without errors. Version-Release number of selected component (if applicable): ModemManager-glib-1.1.0-2.git20130913.fc20.x86_64 ModemManager-1.1.0-2.git20130913.fc20.x86_64 How reproducible: Always in qemu/kvm Never on baremetal Steps to Reproduce: 1. Install Live beta TC2 to a qemu/kvm VM 2. Reboot 3. Wait, then check the journal Actual results: Oct 14 19:34:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemMa Oct 14 19:34:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.free Oct 14 19:34:18 f20sv.localdomain dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemManager1.service' Oct 14 19:34:18 f20sv.localdomain dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.freedesktop.ModemManag Oct 14 19:36:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemMa Oct 14 19:36:18 f20sv.localdomain dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemManager1.service' Oct 14 19:36:18 f20sv.localdomain dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.freedesktop.ModemManag Oct 14 19:36:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.free Oct 14 19:38:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemMa Oct 14 19:38:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.free Oct 14 19:38:18 f20sv.localdomain dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemManager1.service' Oct 14 19:38:18 f20sv.localdomain dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.freedesktop.ModemManag Oct 14 19:40:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemMa Oct 14 19:40:18 f20sv.localdomain dbus[600]: [system] Activating via systemd: service name='org.freedesktop.ModemManager1' unit='dbus-org.freedesktop.ModemManager1.service' Oct 14 19:40:18 f20sv.localdomain dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.freedesktop.ModemManag Oct 14 19:40:18 f20sv.localdomain dbus-daemon[600]: dbus[600]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.ModemManager1.service': Unit dbus-org.free lines 1-51/51 (END) Expected results: Something similar to baremetal: [root@f20s Videos]# journalctl -b | grep -i modem Oct 14 10:56:11 f20s.localdomain systemd[1]: Starting Modem Manager...

This bug is not related to loss of avahi/mdns. A system without ModemManager installed exhibits the same problem.
This is the same as: https://bugzilla.redhat.com/show_bug.cgi?id=1018017 There is an initial upstream patch at: https://bugzilla.gnome.org/show_bug.cgi?id=703040 Please close this as duplicate of 1018017
