Yes, that makes sense. Thanks.

Hi,
For CentOS 7, I set the host in global maintenance, and then upgrade
the engine.
After that, reboot cleanly the engine and set the maintenance back to
none.
Then you should update the host itself. To do that, you are strongly
advised to shutdown the VMs first.
If sanlock or vdsm get upgraded in the process, all your VMs will be
terminated anyway, and this oculd lead to bad results.
So if you don’t have another host, shutdown everything except engine,
set to maintenance global, update engine, reboot engine, shutdown
engine, update host, and then set maintenance back to none.
Does that make sense?

I've been digging through the 4.0 documentation since I'd like to
upgrade in the not to distant future so I'm doing research and I'm
confused.
I'm running 3.6.6 in a hosted Engine environment. My engine runs
in a vm on the host. The host is a physical box and the VMs are
stored on a NAS accessed by an iSCSI LUN, I have no other hosts
running so I can not migrate.
According to this link, https://www.ovirt.org/release/4.0.0/, I'm
told to simply run yum update ovirt-engine-setup and then
engine-setup but I assume that's for a non hosted-engine
environment. I then go to the link for
Hosted_Engine_HOwto#Upgrade_Hosted_Engine guide and am told to do
this.
Set hosted-engine maintenance mode to global and other stuff that
is written assuming I have some place to migrate my VMs to. I do
not have another host.
So how do I properly move to oVirt 4.0 from 3.6.6 on a single
physical host running a hosted Engine VM?
Thanks.
