Hello,

the packages you're referring are not available through yum on hosts.
I've seen that only specific packages are included from repos, does
these packages are excluded?

ovirt-node is designed to just update itself as a firmware.

any additional packages is treated as 3rd party rpm which will be persisted on upgrade.

In order to install the hooks on node you need to enable the ovirt repositories in /etc/yum.repos.d

For installing the hooks on al new hosts during deploy you can do on the engine host / vm:

# echo vdsm-hook-macspoof > /usr/share/ovirt-host-deploy/plugins/ovirt-host-deploy/vdsmhooks/packages.d/vdsm-hook-macspoof.centos

# echo vdsm-hook-nestedvt > /usr/share/ovirt-host-deploy/plugins/ovirt-host-deploy/vdsmhooks/packages.d/vdsm-hook-nestedvt.centos

And whenever you'll add a new node, those packages will be installed. Just remember to enable the repository before adding the new host to the engine.

Packages and configuration will be persisted on upgrade.
