Hello,
on my cluster that has an history from 4.0.6 to 4.1.9 I find vdsClient installed.
I don't remember if I manually installed it or if it was part of a default/standard install.

Now that it is deprecated:
https://www.ovirt.org/develop/developer-guide/vdsm/vdsclient/

I notice I have not the vdsm-client package installed.
Does it make sense to automatically pull it in for upgrades?
Thanks,
Gianluca
