| 15 | f0caa4be | Jose A. Lopes | ----------- |
| 16 | f0caa4be | Jose A. Lopes | |
| 17 | f0caa4be | Jose A. Lopes | The KVM daemon is responsible for determining whether a given KVM |
| 18 | f0caa4be | Jose A. Lopes | instance was shutdown by an administrator or a user. |
| 19 | f0caa4be | Jose A. Lopes | |
| 20 | f0caa4be | Jose A. Lopes | The KVM daemon monitors, using ``inotify``, KVM instances through |
| 21 | f0caa4be | Jose A. Lopes | their QMP sockets, which are provided by KVM. Using the QMP sockets, |
| 22 | f0caa4be | Jose A. Lopes | the KVM daemon listens for particular shutdown, powerdown, and stop |
| 23 | f0caa4be | Jose A. Lopes | events which will determine if a given instance was shutdown by the |
| 24 | f0caa4be | Jose A. Lopes | user or Ganeti, and this result is communicated to Ganeti via a |
| 25 | f0caa4be | Jose A. Lopes | special file in the filesystem. |

| 30 | f0caa4be | Jose A. Lopes | The KVM daemon monitors Qmp sockets of KVM instances, which are created |
| 31 | f0caa4be | Jose A. Lopes | in the KVM control directory, located under |
| 32 | f0caa4be | Jose A. Lopes | ``@LOCALSTATEDIR@/run/ganeti/kvm-hypervisor/ctrl/``. The KVM daemon |
| 33 | f0caa4be | Jose A. Lopes | also creates shutdown files in this directory. Finally, the KVM |
| 34 | f0caa4be | Jose A. Lopes | daemon's log file is located under |
| 35 | f0caa4be | Jose A. Lopes | ``@LOCALSTATEDIR@/log/ganeti/ganeti-kvmd.log``. Removal of the KVM |
| 36 | f0caa4be | Jose A. Lopes | control directory, the shutdown files, or the log file, will lead to no |
| 37 | f0caa4be | Jose A. Lopes | errors on the KVM daemon. |
