I just updated and rebooted a VM host server which runs CentOS 6.5/x86_64. After rebooting, I can't start the virtual-manager due to the error: Error starting Virtual Machine Manager: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ [^] for information. (Details - 1: Failed to get connection to session: Failed to connect to socket /tmp/dbus-Q6...: Connection refused). I have tried: service messagebus restart service libvirtd restart If I manually start dbus, it works and I can run my VMs: dbus-launch --exit-with-session virt-manager Any ideas on how to fix this? -- Wade Hampton
