For the repo part I posted a question for clarification:
http://lists.ovirt.org/pipermail/users/2016-July/040910.html
see there for follow ups

In my case for single host environment with both host and hosted engine
(deployed as appliance) on CentOS 7.2 and storage domains on NFS served by
the host itself, this is the flow I followed to bring a 3.6.5 environment
to 4.0.
Problem still here is inability to upgrade the only existing cluster to 4.0
and then the datacenter to 4.0
Currently not possible due to :
https://bugzilla.redhat.com/show_bug.cgi?id=1351533

To update I kept valid what explained in the thread started here:
http://lists.ovirt.org/pipermail/users/2016-June/040649.html


yum update doesn't propose ovirt 4.0 packages
So I installed ovirt 4.0 repo (as in clean install description) and
disabled 3.6 ones.

yum update "ovirt-engine-setup*"

gives

PROBLEM: automatic reboot of node....
I asked for clarification here:

http://lists.ovirt.org/pipermail/users/2016-July/040912.html


In the mean time I manually let start the host in single user mode enabling
then only rsyslog, networking and ssh and

yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm

disable ovirt-3.6 repos

yum update --exclude=ovirt-hosted-engine-setup,ovirt-engine-appliance

(otherwise getting error on dependencies)

Is this ok [y/d/N]:


Then I put in place vdsm.conf.rpmnew changing inside it

[addresses]
management_ip = 0.0.0.0

This is necessary because I have disabled ipv6 at system os level and this
setting forces vdsmd to listen on IPV4, that is not the default.
Other settings I had in 3.6 vdsm.conf (put in by initial installation) were
not explicitly inserted because they already are the default ones. they are:
ssl=true
and
management_port = 54321

reboot host

after some minutes engine vm starts ok

Wait for stabilization.

All seems up and I'm able to boot and connect to my VMs.

At the beginning the host results as needing for upgrades, but after couple
of minutes the engine detects that it is ok, from a components version
point of view.

In webadmin portal I still see the host with exclamation mark on side of it
because of course I've not configured power management in this single host
environment.
Only thing I don't understand is that I also see an icon on side of host (I
don't understand its graphic; it seems a crown, or a tower ) and when I
mouse over it I see the tooltip

Action Items

But I  don't understand how should I manage it...
