Call "HostServiceSystem.Start" for object "serviceSystem" on ESXi "10.0.0.5" failed.
Turns out that more people are having this problem on ESXi, but there is an easy fix.
ssh into your server and run:
-
esxcli system snmp set --communities public
- esxcli system snmp set --enable true
- /etc/init.d/snmpd restart
