Hi petr,
I followed your instruction last mail, re-install an Centos 7.2
1503(ip:192.168.0.117), and executing 'yum install
http://plain.resources.ovirt.org/pub/ovirt-4.0-pre/rpm/el7/noarch/ovirt-release40-pre.rpm'
On the new system.
Creating an cluster using ovs-based network, and install
vdsm(192.168.0.117); deploy log shows that meeting an error as follows: But I
cann't find out the code which implements the function of setupNetworks,
Just find the setupNetwork() function was defined in API.py, what does this
function do actually, where is the code ? and how to fix this error?

4.0.2? Thank you
If everything goes well, it will be in master this week. I don't know when it
will be part of 4.0.
I installed master VDSM patched with
https://gerrit.ovirt.org/#/q/topic:ovs_acquire on my host (Fedora 23 with
disabled NetworkManager) and it worked OK. You can try to build it on your own
[1]. If you hit any problem, feel free to ask.
We'd like to go that way, but nothing specific yet.
