Resolution

Use SSL to connect to Virtual Center by adding the "-z" option when running fence_vmware_soap on the command line, or 'ssl="1"' in /etc/cluster/cluster.conf.  For example:

<fencedevice agent="fence_vmware_soap" name="vmware-fence" ipaddr="192.168.2.5" 
             login="Administrator" password="***" ssl="1"/>

SSL support will need to be configured on Virtual Center. Please consult VMware on how to do this.

Root Cause

  • SSL support was not enabled on Virtual Center or in the fence device configuration.
