migrate to Hosted engine set up using ovirt node 3.6
Hi I am in the process of upgrading my ovirt DC to 3.6. I would like to migrate to hosted-engine with gluster replica 3 storage in the process. The engine has been upgraded and I have installed 3 of the VM hosts in one cluster using the ovirt-node iso. I have three other VM hosts in a separate cluster to upgrade. I see an option to configure the hosted engine through the node admin login tui, however I have not found any up to date instructions on how to perform a migration to hosted using the ovirt-node. I thought I'd ask a few questions before I started: Should I connect and approve the node in the current engine prior to configuring the hosted engine? Does the node hosted-engine-setup provide a pause to restore the engine db from the external engine? Or even better a facility to upload the database backup file? Any feedback gratefully received. Thanks, Alastair

http://www.ovirt.org/Migrate_to_Hosted_Engine hosted-engine-setup has to be run on the host. engine-setup has to be run on the engine VM. The DB restore from you previous setup has to be performed on the engine VM. If you are using the ready to use oVirt engine appliance and you choose to automatically execute engine-setup on your VM it will not wait for you to replace the engine DB so you have just to avoid that and manually execute engine-setup on the engine VM. In this way you have all the time to perform your import.
Any feedback gratefully received.
Thanks, Alastair

Yes I am familiar with these instructions, however they are quite old and have not been updated to include any information about how to perform this in the case of using the 3.6 ovirt-node image as the host and the ovirt-live installation image as the VM installation.
hosted-engine-setup has to be run on the host. engine-setup has to be run on the engine VM. The DB restore from you previous setup has to be performed on the engine VM. If you are using the ready to use oVirt engine appliance and you choose to automatically execute engine-setup on your VM it will not wait for you to replace the engine DB so you have just to avoid that and manually execute engine-setup on the engine VM.
This is the crux: if the hosted-engine-setup using the live image allows you to pause the setup and do a manual engine-setup. Its seems like it is probably a quite common thing for people to want to do so I thought I'd check. If it has not been attempted and/or documented then I will try it.
In this way you have all the time to perform your import.

Hosted-engine-setup will ask you about automatic execution of engine setup on the engine VM. You have just to respond no at that question.
