Ummm.. I realize it's been a while but aren't you supposed to install ovirt-engine-setup and not ovirt-engine?

thanks Gianluca for the well thought out response.   I started over and tried to install RHEL 8 with ovirt 4.4.   I ran into a few problems, which may be related.   First was that the module javapackages-tools could not be found.

Then, the install of ovirt-engine relies on apache-commons-compress, but no version could pass module filtering.

Sorry for the length of these errors.   I just thought --nobest might find something for me.

Here is the enabled modules....

Hi,

I am laying the groupwork for upgrade ovirt to 4.4.   Since the standalone ovirt mgr is now running on RHEL 7, I have installed RHEL 8 to a new VM.   Unfortunately, after installing ovirt-release43, I am not able to find documentation for the dnf modules required.   All the current documentation point to ovirt-release44 and dnf modules not available for ovirt 4.3/RHEL 8.

oVirt 4.3.x (both engine server and hypervisors) are only based on CentOS 7.x or RH EL 7.x

oVirt 4.4.y (both engine server and hypervisors) are only based on CentOS 8.x or RH EL 8.x

I think 4.3 on RH EL 8 never tested at all by the developers.

If your target is upgrade from 4.3 to 4.4 you have to do an "application" backup of the 4.3 engine (see the link at the bottom) and restore it on the new engine in 4.4, that is a scratch install on a new system, but can have the same ip/hostname as the old engine server, so that it could be transparent from an user access point of view.

Already done both on oVirt and RHV with external engine, local database.

The old engine and the new one are two vSphere virtual machines.

You can install the new engine based on RH EL 8 with temporary network parameters and then as soon as you have completed the backup of the 4.3 one and copied over it you can shutdown the 4.3 engine server, to keep at a minimum the absence of an engine for the environment that anyway doesn't compromise the workload of your virtual machines.

Of course HA reactions or live migration are not possible in this time frame without an engine.

The restore and the reconfiguration take minutes if you prepare the new engine server in advance.
