Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1486353

Description of problem:

We have enabled the "VirtIO serial console" option on all our RHEV VM's.
When we update a running host in the satellite system (e.g. Content View) then satellite contacts RHEVM and disables the "VirtIO serial console" option.

Version-Release number of selected component (if applicable):

Red Hat Satellite Version: 6.2.10-4.0.el7
Red Hat Virtualization Manager Version: 4.1.1.8-0.1.el7

How reproducible:

100% (Reproduced internally also on 6.2.11)

Steps to Reproduce:
1. Have RHEV4 VM running on RHEV-M
2. Enable VirtIO serial console option on such VM under rhev4-manager (Edit -> Console, "Enable VirtIO serial console"
3. Change any parameters over webui for the VM under Hosts (changing CV here).

Actual results:

Enable VirtIO serial console option is not enabled anymore when any parameters for the VM is changed over Satellite's webui.

Expected results:

Enable VirtIO serial console option on RHEV VM should stay enabled regardless of the actions done on VM over Satellite.
