Fixed In Version:
Doc Type:	Enhancement
Doc Text:	Previously, every host in a self-hosted engine environment stored a configuration file for the self-hosted engine virtual machine. As a result, any change to the configuration required users to update the file on each host. Now, a single self-hosted engine configuration file is saved on shared storage, and can be accessed by all hosts.

Description Doron Fediuck 2014-09-09 11:59:40 EDT

Description of problem:
Currently every host has a configuration file for the hosted engine VM.
If a change is needed files in all hosts should be fixed.

So we should be storing a single file in a shared storage to simplify it.

Hi Doron,
Should this require from us to use shared storage at all times for HE, thus turning shared storage to basic requirement for the deployment?

the requirement already exist today: we create a DC, domain and disks for the
engine-vm. NFS,glusgter,iscsi, we see them all as non-local.

our goal is to alleviate ovirt's backup of vms in special disks for shared configuration for both the VM and the broker conf

Comment 5 Elad 2016-01-26 03:56:20 EST

Hosted engine VM configuration is being saved on the shared storage. Executed hosted engine sanity over all supported storage types (NFS, iSCSI, Gluster, FC) to check there are no regressions, all passed.

In addition, checked that the configuration exist in the shared storage under /rhev/data-center/pool/HE-SD/conf-img/

The following files are saved there:
vm.conf, version, fhanswers.conf, hosted-engine.conf, broker.conf


Tested using:
