Doc Text:
There are several cluster or host settings which will require host reinstallation if the settings are changed. A host must be reinstalled if you any of its following settings are changed: - Turn off/on Kdump integration. - Change command line parameters. All hosts in a cluster must be reinstalled if you change the firewall type of the cluster. In addition to the existing documentation and Warning event, an exclamation mark icon will now be added to each host that needs to reinstalled. When exclamation mark icon is shown, you can find the details about it in Host detail view within Action Items section.

Description Germano Veit Michel 2017-08-11 01:47:03 EDT
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 3 Martin Perina 2017-09-11 03:35:40 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

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.

Exclamation mark is displayed, but no particular error/warning is shown anywhere, I would expect some text in hosts detail view.

Using version ovirt-engine-4.2.0-0.0.master.20171105155215.git59d3324.el7.centos.noarch
