Description Yedidyah Bar David 2017-09-13 10:01:09 UTC

+++ This bug was initially created as a clone of Bug #1460609 +++

Description of problem:
Consolidate ovirt host requirements to a single meta package, to deal with the current package installation and upgrade issues.

Infra and integration need to agree on one place where the list of required packages are installed/updated per arch per version.

--- Additional comment from Martin Perina on 2017-06-12 11:19:36 IDT ---

Since 3.6 it's no longer true that all package dependencies on the host are handled by RPM dependency of VDSM. At the moment some we have several place where packages for the host required by oVirt are defined:

1. vdsm package dependencies (defined per VDSM version)
2. ovirt-host-deploy package list (defined per ovirt-host-deploy version)
3. Host upgrade manager package list (defined per cluster version)

This status makes nearly impossible to achieve the same package status for different upgrade methods:

1. Manual 'yum update' on the host
2. Executing host 'Upgrade' from webadmin
3. Executing host 'Reinstall' from webadmin

So we need to move host package dependencies on the host by create ovirt-host-X.Y.Z package which will define dependencies of the host for specific oVirt X.Y.Z

What's the question?

--- Additional comment from Yaniv Lavi (Dary) on 2017-06-12 11:43:07 IDT ---

The goal should be:
- In host deploy only this package is required to get all deps installed per arch, per version.
- Engine only updates this package to get the oVirt deps updated 
- The node only requires this package to build.

The host side holds the list of packages to update so that (to remove the need of engine being aware of the host version\arch):
- Node host lists only the image rpm name to update.
- RHEL-H only lists this meta-data package to update.

No, node and non-node hosts differ at least in imgbased and nodectl presence.
We need to decide if we want to enforce all the other packages installed on node to be also installed on plain hosts.

Copied doc text from 4.2 clone bug 1460609.

Comment 5 Yedidyah Bar David 2017-10-30 07:49:40 UTC

Tahlia, you might want to mention that it's only required in 3.6 if you want to add a 3.6 host to a future 4.2 engine. Otherwise people might rightfully ask why they need such a new package so late in the 3.6 lifecycle.

Comment 6 Tahlia Richardson 2017-10-31 06:03:42 UTC

Thanks Didi, I've added that in.

Comment 7 Pavol Brilla 2017-10-31 11:52:13 UTC

ovirt-host package exist and it is installing all dependencies for host

# yum list ovirt-host vdsm
Installed Packages
ovirt-host.noarch                  3.6.0-1.el7ev                    @rhv-3.6.12                        
vdsm.noarch                        4.17.43-1.el7ev                  @rhel-7-server-rhev-mgmt-agent-rpms


Add host to 4.1 engine did not install any other package to host
