Hello,
on February I installed OVN controller on some hypervisors (CentOS 7.3 hosts).
At that time the vdsm-tool command was part of vdsm-python-4.19.4-1.el7.centos.noarch
I was able to configure my hosts with command

vdsm-tool ovn-config OVN_central_server_IP local_OVN_tunneling_IP

as described here:
https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/
and now here
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/administration_guide/sect-adding_external_providers

I have 2 hosts that I added later and on which I want to configure OVN external network provider too.

But now, with vdsm-python at version vdsm-python-4.19.10.1-1.el7.centos.noarch I get an usage error trying to execute the command

[root@ov301 ~]# vdsm-tool ovn-config 10.4.192.43 10.4.167.41
Usage: /bin/vdsm-tool [options] <action> [arguments]
Valid options:
  -h, --help
Show this help menu.
  -l, --logfile <path>
...

Also, the changelog of the package seems quite broken:

[root@ov301 ~]# rpm -q --changelog vdsm-python

* Thu Nov 02 2006 Simon Grinberg <simong@qumranet.com> -  0.0-1
- Initial build

[root@ov301 ~]# 

How can I configure OVN?

Thanks in advance,
Gianluca
