Created attachment 1228475 [details] it is engine.log for ovirt Description of problem: Hi, We can not add host from ovirt-engine.While we add host we had an error.I attached the error message.Setted up 7.2 Centos and 4.0 ovirt on this server.I m trying to add host which is had Red-Hat 6.7. Version-Release number of selected component (if applicable): oVirt 4.0 Steps to Reproduce: 1.İnstall CEntos 7.2 2.İnstall ovirt-engine onto Centos 7.2 3.Try to add host a running which had Red-Hat 6.7 via ovirt-engine Actual results: Red-hat 6.7 host have to add on oVirt Expected results: it should be configure as a node on ovirt Additional info:
We do not support EL 6.x hosts in oVirt 4.0. The only question is if the failure is understood from the error messages or not. It does indeed seem like we fail badly.
The failure is due to recent otopi relying on python >= 2.7. Since we knew we do not need to support 2.6 anymore, we allowed ourselves to use 2.7 syntax. But we didn't fix the code to fail nicely.
Thanks for answer Yedidyah, Which ovirt version support EL 6.x or not? if not support ,can you update your web page because we waste our time :( Thanks, Best Regards.

Patch merged to master, moving to MODIFIED. With this, trying to install a centos6 host emits this event: Failed to install Host h1. Python version 2.6 is too old, expecting at least 2.7. Sandro - is it enough? Also please flag etc. if we want this in 4.0. Thanks.
"4.0 supports only el7. Please check the release notes [1]. Where did you see otherwise" Okay but my question is different.I asked; "Which ovirt version support EL 6.x or not?" Thanks, Best Regards.

This depends on definition of "support". oVirt 4.0 only ships packages for el7 hosts. It can still manage existing el6 hosts with 3.6 packages, in 3.6-compatibility mode. I do not think you can add new 3.6/el6 hosts, not sure, didn't check. oVirt 3.6 was the last version fully supporting el6.
Thanks for answering.I will try to use 3.6 and i hope it can help me for adding 6.7 hosts. Thanks, Best Regards.

Hi Yedidyah, I tryed to use oVirt 3.6 and try to add el 6.7 host.But i had different error.I attached the engine.logs.Can you help me? or if you want i can create a new bug or we can continue here. Thanks, Best Regards.
Please backport to 4.0.7 as well. In 4.0 we already dropped compatibility with versions older than 3.6 so no el6 hosts can be handled there too. There's no support for 3.6/el6 hosts, 3.6 already was el7 hosts only.

General support for oVirt is on: http://www.ovirt.org/community/ Bugzilla is for bugs. If you found a bug (didn't check logs yet, I am on a train), please open a new one. Thanks!
Hi Yedidyah, I opened new bug before 3 days.The bug number is "Bug 1403219" Thanks, Best Regards.
adding RHEL 6.8 host to engine 4.1 returns error 'Python version 2.6 is too old, expecting at least 2.7.' verified in ovirt-engine-4.1.0.2-0.1.el7.noarch with otopi-1.6.0-1.el7ev.noarch
