VMware vCenter Server Appliance: Error: VPXD must be stopped to perform this operation.

I've been playing with the VMware vCenter Server Appliance and stumbled across the following error while setting up the vCenter Database:

Error: VPXD must be stopped to perform this operation.

To resolve this issue, ssh into the vCenter Server Appliance and run the following command:

vCenter Server Appliance:~ # chkconfig
after.local              off
apache2                  off
atftpd                   off
auditd                   on
.
### actual output cut..

.
vmware-inventoryservice  off
vmware-netdumper         on
vmware-rbd-watchdog      off
vmware-sps               off
vmware-tools             on
vmware-vpxd              on
vsphere-client           on
xinetd                   off
ypbind                   off

Confirm that the vmware-vpxd service is "on".  Then, run the following:
vCenter Server Appliance:~ # chkconfig vmware-vpxd off

Perform the needed function, then run the following to restart the vpxd service:
vCenter Server Appliance:~ # chkconfig vmware-vpxd on
