[ovirt-users] oVirt 3.6.7 upgrade to 4.0.5 and CentOS 7.3

[ovirt at timmi.org]

Hi all,

please note that I have upgrade my oVirt 3.6.5 environment to 4.0.5 
without problems.
I saw some network messages in my evens but I will post them later in a 
separate thread.

Really great work how the upgrades are working.

Best regards
Christoph
