Environment

VMware vCenter Server Appliance 6.7.x
VMware vCenter Server Appliance 6.5.x

Cause

The error is caused by a wrong xml syntax in vpxd.cfg

In the above example vpxc.cfg had a  missing closing symbol (>) for cluster tag.
/etc/vmware-vpx/vpxd.cfg
<cluster>
      <VMOverheadGrowthLimit>-1</VMOverheadGrowthLimit>
</cluster

Resolution

fix the syntax in vpxd.cfg

XML validators like https://www.xmlvalidation.com/ can be used to find the line with incorrect syntax or restoring vpxd.cfg from older backup can help .
