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

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