During upgrade, the host was not able to get restarted from UI, as I did not configured remote power management.

I've restarted it manually and after that, host seamed upgrading something and then it got rebooted on its own again and then started with black screen and did not let me to log in for a few minutes (15-20), then I received the login prompt.
I tried to activate the host from UI and host successfully activated.

Red Hat Enterprise Linux release 7.5

How reproducible:
100%

Steps to Reproduce:
1.Deployed SHE on 4.1RHVH.
Components on host:
ovirt-hosted-engine-ha-2.1.11-1.el7ev.noarch
ovirt-hosted-engine-setup-2.1.4.2-1.el7ev.noarch
Linux 3.10.0-862.el7.x86_64 #1 SMP Wed Mar 21 18:14:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
Red Hat Enterprise Linux release 7.5-0.14
2.Added additional 4.1RHVH as ha-host.
3.Checked for upgrade for one of the hosts via UI.
4.Upgrade 4.1RHVH from UI to 4.2RHVH by clicking "Install"->"Upgrade".

Actual results:
Failed to upgrade Host is displayed in logs in UI.

Expected results:
User should be properly warned that proper host's reboot is mandatory, so customer will be able to properly configure power management for all RHVHs.

Comment 1 Martin Perina 2018-09-03 14:33:12 UTC

Ondro, we are restarting hosts after upgrade in RHV 4.2 using SSH and not power management, right? If so, then I suggest to close it as not a bug

Comment 2 Avital Pinnick 2018-09-04 08:58:06 UTC

Martin, 

All of the host upgrade procedures in the current Upgrade Guide say "After the upgrade, the host is restarted." Is there any reason to change the text?

Example: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html-single/upgrade_guide/#Proc-Updating-Linux-Hosts-4_0
