Hi Paul

Thank you for bringing this to my attention.

It does look like I will need to upgrade all my hosts to CentOS 7.

But would the prevent me from changing my cluster compatibility version to 3.6?

Thanks

Hi Shani

Yes, I did try and change the cluster compatibility first, and that's when I got the error: Ovirt: Some of the hosts still use legacy protocol which is not supported by cluster 3.6 or higher. In order to change it a host needs to be put to maintenance and edited in advanced options section.

I did go through the article you suggested, however, I did not see anything that would help.

Thanks

Hi Jonathan,

Did you try first to change the compatibility of all clusters and then change the data center's compatibility?

This once seems related: https://bugzilla.redhat.com/show_bug.cgi?id=1375567

Good Day

I have been trying to upgrade a clients oVirt from 3.6 to 4.0 but have run into an issue where I am unable to change the cluster and data center compatibility version.

I get the following error in the GUI:

Ovirt: Some of the hosts still use legacy protocol which is not supported by cluster 3.6 or higher. In order to change it a host needs to be put to maintenance and edited in advanced options section.

This error was received with all VM's off and all hosts in maintenance.

The environment has the following currently installed:

Engine - CentOS 7.4 - Ovirt Engine 3.6.7.5
Host1 - CentOS 6.9 - VDSM 4.16.30

Host2 - CentOS 6.9 - VDSM 4.16.30

Host3 - CentOS 6.9 - VDSM 4.16.30

I also have the following from engine.log
