If the UI is reporting anything new for a shutoff VM in _any_ of the graphs, then it's a virt-manager bug. Please try to reproduce with virt-manager upstream: git clone git://git.fedorahosted.org/virt-manager.git cd virt-manager ./virt-manager --debug And if you reproduce, take the --debug output and file an upstream bug report: https://virt-manager.org/bugs/ Thanks, Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
