VM Home Assistant automatic restart with UserScripts

My Home Assistant VM crashed nearly daily. Search for the logfile error or supervisor repair could not change anything so far.

Here is a Script for the "User Scripts" Plugin, to restart crashed VM:

#!/bin/bash
if netcat -z  Home.Assistant.IP.Nr  8123 >/dev/null; then
# if curl --url http://Home.Assistant.IP.Nr:21080 >/dev/null; then
    echo "HAonline"
else
    echo "HAoffline reboot"
        virsh destroy  'Home Assistant'
        virsh start 'Home Assistant'
fi 

Costum Schedule 0,6,12,18,24,30,36,42,48,54 * * * * (every 6 min)

not the most elegant solution, but it works
