Whiteboard:
Fixed In Version:		Doc Type:	Enhancement
Doc Text:	Previously, the self-hosted engine setup failed if the system clock was set to a time zone that was behind UTC during the installation. This is due to the fact that the Red Hat Virtualization Host generates VDSM certificates at the first boot and if the clock is incorrect, the chronyd or ntpd processes resynchronized the clock. This lead to an invalid certificate if the time zone was behind UTC. Now, Red Hat Virtualization Host generates the certificates after the chronyd or ntpd processes, and waits two seconds for the clock to synchronize. Note that if the Red Hat Virtualization Host is configured after the installation, or if the NTP server is too slow, the self-hosted engine setup may fail.	Story Points:	---

Description rhev-integ 2017-05-30 15:14:43 UTC

+++ This bug is a downstream clone. The original bug is: +++
+++   bug 1422982 +++
======================================================================

Description of problem:
rhevm-appliance has no swap by default, this is contrary to 
https://access.redhat.com/solutions/15244
where a system with 16GiB of RAM should have at least 8GiB of swap.

Version-Release number of selected component (if applicable):
rhevm-appliance-20161214.0-1.el7ev

How reproducible:
Always

Steps to Reproduce:
1. Install RHV using the hosted engine (rhevm-appliance)
2. launch free -m on the appliance

Actual results:
No swap

Expected results:
8GiB+ swap

Additional info:
swap is required especially since additional tools must be installed on the manager (3rd party backup tools, etc) which might increase memory pressure.

Hi Ryan. I'm looking at the doc text. Could you pls. explain what you mean by "user additions"? Thanks!

Comment 3 Ryan Barry 2017-06-20 12:34:39 UTC

I'm imagining vendor tools or something which a customer environment requires for standardization (powerbroker, etc)

Comment 4 Gonza 2017-06-21 07:39:33 UTC

Verified with:
rhvm-appliance-20170619.0-1

[root@10-34-61-172 ~]# free -h
total        used        free      shared  buff/cache   available
Swap:          8.0G          0B        8.0G
