To copy the contents of the file to the problem host:

2. Go to the directory /etc/vmware:
   
   cd /etc/vmware
3. Run this command to backup the snmp.xml file.
   
   cp snmp.xml snmp.xml.bkup
4. Copy and paste this content into the snmp.xml file:
   
   <?xml version="1.0" encoding="ISO-8859-1"?>
   <config>
   <snmpSettings>
   <enable>true</enable>
   <port>161</port>

Trying to start snmpd on vmware from where i get the following error:
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
