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.
