Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: The configuration of the HE VM was saved but not propagated to the shared storage. Consequence: Hosted engine tooling did not see the updated configuration and had to wait for the normal OVF refresh cycle. Fix: The engine was fixed to push the configuration update to the storage domain immediately. Result: Hosted engine tooling on hosts should see the OVF with updated values almost instantly (meaning about a minute or so).

Description Roy Golan 2016-05-29 07:38:21 UTC 
Description of problem:
 Once the HE VM config has been changed we must wait for the interval of OvfUpdateIntervalInMinutes to kick in. In HE scenario we would like to eagerly run this operation to prepare for the next run ASAP.

Version-Release number of selected component (if applicable):
 -relevant component is only ovirt-engine 3.6.6

How reproducible:
 100%

Steps to Reproduce:
 1. Update the HE VM
 2. Wait for the OvfUpdater to kick in
 3. See the fresh vm.conf under each HE host updated at /var/run/ovirt-hosted-engine/vm.conf

Actual results:
 - Must wait for OvfUpdater to perform the update

Expected results:
 - Immediately after finishing the Update VM command go and update the OVF
Comment 2 sefi litmanovich 2016-08-02 10:54:26 UTC 
So far failed to see the effect after hotpluging memory to the HE vm.

Set the agent.log to DEBUG level.
added memory to the vm (8192 instead of 4096), the change is reflected in the webadmin but fails in practice:

2016-08-02 06:17:38,094 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-32) [3c39f550] Correlation ID: 3c39f550, Call Stack: null, Custom Event ID: -1, Message: Failed to hot set memory to VM Hos
tedEngine. Underlying error message: unsupported configuration: maxMemory has to be specified when using memory devices 

OVF is expected to update with the new values anyway, but doesn't.
Attaching both engine log and agent log.. notice the 7 hour offset in the time stamp between the logs -> in engine log 06:00 would be 13:00.

Comment 4 sefi litmanovich 2016-08-11 08:56:38 UTC 
Verified with rhevm-4.0.2.3-0.1.el7ev.noarch, ovirt-hosted-engine-ha-2.0.1-1.el7ev.noarch.
HE OVF does update ad-hoc, might take several minutes for it reflect in vm.conf.
