Name

       ganeti-kvmd - Ganeti KVM daemon

Synopsis

       ganeti-kvmd

DESCRIPTION

       The KVM daemon is responsible for determining whether a given KVM instance was shutdown by an administra‐
       tor or a user.

       The  KVM  daemon  monitors, using inotify, KVM instances through their QMP sockets, which are provided by
       KVM.  Using the QMP sockets, the KVM daemon listens for particular shutdown, powerdown, and  stop  events
       which  will determine if a given instance was shutdown by the user or Ganeti, and this result is communi‐
       cated to Ganeti via a special file in the filesystem.

FILES

       The KVM daemon monitors Qmp sockets of KVM instances, which are created in the KVM control directory, lo‐
       cated under @LOCALSTATEDIR@/run/ganeti/kvm-hypervisor/ctrl/.  The KVM daemon also creates shutdown  files
       in   this   directory.    Finally,   the   KVM   daemon's   log   file   is  located  under  @LOCALSTATE‐
       DIR@/log/ganeti/ganeti-kvmd.log.  Removal of the KVM control directory, the shutdown files,  or  the  log
       file, will lead to no errors on the KVM daemon.
