Fixed In Version: ovirt-engine-4.1.8.1
Doc Type: Enhancement
Doc Text:
There are several cluster and host settings which require reinstallation of the host if changed. The requirement to reinstall was always mentioned in documentation and a WARNING event was raised. With this release, the Administration Portal now also shows an exclamation mark icon for each host that needs to be reinstalled. When an exclamation mark icon is shown, you can find the details about it in the Action Items section of the host's details view.

Description rhev-integ 2017-10-13 04:34:37 EDT 
+++ This bug is a downstream clone. The original bug is: +++
+++   bug 1480433 +++
======================================================================

Description of problem:

For VMs, if the user changes a configuration that requires the VM to be power cycled to take effect, a tooltip is displayed to inform the user.

However, the same applies for Hosts but and there is no such feature.
Some host configurations require the host to be re-installed in order to be pushed. One example is kdump integration. We have the following note in the 

Documentation:
~~~
When you enable Kdump integration on an existing host, the host must be reinstalled for kdump to be configured. See Section 7.5.12, “Reinstalling Hosts”. 
~~~

This is not user-friendly. This RFE is to create a similar feature for Hosts.

Comment 4 rhev-integ 2017-10-13 04:34:57 EDT 
There are other options which require host reinstallation such as changing kernel command line parameters of the host or changing type of firewall for the cluster, so I'm reopening this RFE to cover all existing scenarios

Comment 6 rhev-integ 2017-10-13 04:35:08 EDT 
Marina, this is not a bug, this is RFE, because all such changes either shows that somehow or the need to reinstall is described in documentation.

Also we are still looking at the scope we don't know yet if we will backport it to 4.1.z. Let's work on it for 4.2 and when done we will see.

Testing on ovirt-engine-4.1.8-0.1.el7.noarch

There is no warning of any kind anywhere to notify me that I have to reinstall the host after adding PM agent and enabling kdump.

The documentation text flag should only be set after 'doc text' field is provided. Please provide the documentation text and set the flag to '?' again.
