Hi, i have seen your log...

It showed that your machine is el7, but when yum install python, it yum install the version of el6... so, i guessed if you used the wrong epel which was for version el6.(?)  Can you show the version of your epel, please? :)

Hi, I have used CentOS 7 as a node on oVirt 3.5 for many times.

On my CentOS 7, the version of python is python-2.7.5-16.el7.x86_64, too. And I found a strange thing, why your python-threading(maybe it's python-pthreading)  was for el6?

I'm using overt engine 3.5.0.1-1.el6 and want add to cluster node with CentOS 7. But a error is appeared when engine install packets:

Failed to install Host 10.169.50.100. Yum python-threading-0.1.3-3.el6.noarch requires python(abi)=2.6

Yum says python-2.7.5-16.el7.x86_64 already installed.

Hi,
yes, it should be possible in 3.5.0 to use el7 as a hypervisor.
