Hosted Engine: add hosts with Web UI

Summary

Allow to deploy additional hosts for Hosted Engine using Web UI

Owner

Detailed Description

  • ovirt-host-deploy must allow to deploy and configure ovirt-hosted-engine-ha daemons
  • ovirt-engine web UI must be changed for allowing the user to set an host as part of Hosted Engine HA cluster

Benefit to oVirt

  • will simplify Hosted Engine deployment on additional hosts

Testing

In order to test the ovirt host deploy part, the following content can be added to ‘’‘/etc/ovirt-host-deploy.conf.d/hosted_engine.conf’’’ on the host, adapting it with the data from first host deployed:

Contingency Plan

  • The additional hosts will still be deployed by running hosted-engine –deploy and related patches will be reverted.
