====VM-Watchdog-Script====
 +
Wenn die VM unerwartet crasht, kann diese per Remote nicht resettet werden.
 +
Dies machen wir automatisiert mit diesem Script, das in /usr/local/bin liegt.
 +
<source lang='bash'>
 +
#!/bin/bash
 +
 +
count=$( ping6 -c 5 fd56:b4dc:4b1e:0:5054:ff:fea6:969e | grep "bytes from" | wc -l )
 +
if [ $count -eq 0 ]
 +
then
 +
  logger "Sim-Papagei: Not available -> Reset VM"
 +
  virsh reset Sim-Papagei
 +
  exit 0
 +
else
 +
  logger "Sim-Papagei: Up and running -> nothing to do"
 +
  exit 0
 +
fi
 +
</source>
 +
 +
Per cronjob wird es alle 20 Minuten ausgeführt
 +
<source lang='text'>
