I like this

How about ovirt-privd?

I like short names.

I think we should use the example of systemd:

systemd
systemctl

So ovirt-hostd, ovirt-hostctl ovirt-hostcli

We want to use /run/ovirt-host/storage/ for that, but this is hard change,
since it breaks migration to from hosts using different vdsm versions.
New vms expect the disks at /rhev/data-center and old vms at /rhev/data-center/

Maybe we can change disks path during migartion on the destination, but
migrating vms to older hosts will be impossible, as the vdsm on the older
machine does not support such manipulation.
