libvirtd: unsupported configuration: cannot find any matching source devices for logical volume group 'dummy_vg' libvirtd: internal error: Failed to autostart storage pool 'dummy_vg': unsupported configuration: cannot find any matching source devices for logical volume group 'dummy_vg'
Workaround from: https://bugzilla.redhat.com/show_bug.cgi?id=1411600
But besides “device path", I also have to remove capacity, allocation and available before the pool would start.
