Hello in my case I have a clean installed 3.6.0 environment with self
hosted engine.
I installed and configured a CentOS 7.1 guest and I'm able to see guest
info.
See screenshot.
https://drive.google.com/file/d/0BwoPbcrMv8mvVVY4NUJiRU0wTU0/view?usp=sharing

But I do have the time zone problem.
I verified that my self hosted engine (I did the deploy through the
provided appliance) was by default configured with UTC timezone.
I then changed it using inside its OS the command:

timedatectl set-timezone Europe/Rome

then I made global maintenance and restarted both the host and the engine.
I still had the exclamation mark.
Then I modified the VM inside the GUI in Edit VM --> System --> General .
As you see in screenshot it was Etc/GMT and then Europe/Berlin.
And finally shutdown/power on (because reboot doesn't instantiate a new
qemu/kvm process)
And now it is ok from an OS point of view andalso GUI point of view.
See:
https://drive.google.com/file/d/0BwoPbcrMv8mvSmp1QjVEMEVPQms/view?usp=sharing

I don't know if the update itself from 3.5 to 3.6 could have scrambled
anything, but in my case all is ok if the various configurations involved
match.

BTW: I noticed that the "Guest Info" visualized data are not so dynamic:
sometimes if I do some changes, I have to click another tab (eg affinity
groups) and then "Guest Info" again to be able to see updated values

A strange thing with guest is that it seems it starts wrong because if
current time is 16:25 I notice right after boot that I get both the "!"
inside the GUI and wrong timestamp inside OS (1 hour ahead):

with apparently chronyd going to set time correctly detecting a huge step:

and after 1-2 minutes time is ok and I don't see any more the "!" in the
ovirt admin gui

but this walking ahead 1 hour right after boot seems still wrong to me.
Donna if it is a problem with CentOS 7.1 itself or oVirt.
