Description Michael Burman 2014-08-05 12:54:34 UTC

Description of problem:
Kdump integration is enabled by default in the [Power Managment] in the new hosts tab. and if i have a problem with kdump integration while installing new host in my setup and i want to disable kdump integration, i need first to enable Power Managment, then disable kdump integration and disable the power managemnt again.
For my opinion it is very weird that i have to do so. I expect to enable/disable kdump integration without enabling Power Management first and disabling it back. 

Version-Release number of selected component (if applicable):
 oVirt Engine Version: 3.5.0-0.0.master.20140722232058.git8e1babc.el6 

How reproducible:
always

Steps to Reproduce:
1. Create new host under hosts tab.
2. In Power Management, kdump is enabled by default and the only way to disable it, is by enabling power management. 
3.

Actual results:
In Power Management, kdump is enabled by default and the only way to disable it, is by enabling power management. 

Expected results:
I expect to enable/disable kdump integration without enabling Power Management first and disabling it back.

Comment 1 Martin Perina 2014-08-22 11:17:47 UTC

Kdump integration should be enabled by default for new hosts, but it doesn't have any meaning if power management is disable. On the other hand when user enables kdump integration on existing host, host needs to be redeployed to activate kdump integration. So the solution is:

1) Do not configure kdump integration during host deploy if host PM is not enabled

2) Show warning to user after updating host when PM and kdump integration are enabled, but kdump integration is not configured on host

Comment 2 Michael Burman 2014-09-15 07:30:07 UTC

This is the behavior:
1. If PM is off, kdump integration is not configured during host deploy even when it's on

2. If PM is off and kdump integration is on, there's no warning message after host is deployed, that kdump is not configured

So to verify this i execute:
1. PM off, kdump integration off -> kdump integration is not configured during host deploy - no warning

2. PM is on,  kdump integration off -> kdump integration is not configured during host deploy - no warning

3. PM off, kdump integration on -> kdump integration is not configured during host deploy - no warning

4. PM on, kdump integration on -> kdump integration is successfully configured during host deploy - If for some reason, kdump integration hasn't configured successfully, should be warning about this

Verified on - 3.5.0-0.12.beta.el6ev

Comment 3 Sandro Bonazzola 2014-10-17 12:20:31 UTC

oVirt 3.5 has been released and should include the fix for this issue.
