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
