In OMIVV, when you deploy the OMSA agent by using
the Fix non-compliance hosts link available in the Fix Non-compliant vSphere Hosts wizard, OMIVV performs
the following action:
Starts the HTTP Client service
Enables port 8080
Makes the port available for ESXi 5.0 or later to download and install OMSA VIB
After the OMSA VIB installation is complete, the service automatically
stops and the port is closed.
