Hi there and welcome aboard!

= Noob questions =
A) First time here. I couldn't find the rulebook/netiquette for oVirt mailing

list, could you give me a link?

Asking questions regarding to ovirt is a part of this mailing porpuses, so I don't think there's a rulebook.

It was meant to help you and others :)

For my opinion, just try to be as imformative as you can.

If there's some more needed information, you'll probably be asked to supply it :)

B) What do you use here, top or bottom posting?

Depends on you.

C) Which is the line length limit? I've written this email manually entering
new line after 80 chars, is it fine?

Once again - your call :)

D) Which is the log length limit?

It's better to keep it focused on your issue, but not too short - basically it should contain the operation you're trying to do.

If some more logs are needed, you'll be asked to add them.

E) When should I use pastebin or similar websites?

As much as I know, attaching the logs as mail attachments are more common.

It's worth checking if the data you've pasted on patebin will be expired eventually, so I personally think that attaching the logs here is will be more durable.

TL;DR
self host engine deployment fails, vdsmd.service has this error I can't find on
Google:
'sysctl: cannot stat /proc/sys/ssl: No such file or directory'

Long description:
I've been trying for a while to deploy an oVirt self hosted engine but it failed
all the time. After every failed deployment, node status resulted in 'FAIL' (or
'DEGRADED', I don't remember) and to restore it to 'OK' status I'd to run
'vdsm-tool configure --force'.

vdsm-tool configuration never went through fully successful:
< code >
abrt is not configured for vdsm
lvm is configured for vdsm
libvirt is not configured for vdsm yet
FAILED: conflicting vdsm and libvirt-qemu tls configuration.
vdsm.conf with ssl=True requires the following changes:
libvirtd.conf: listen_tcp=0, auth_tcp="sasl", listen_tls=1
qemu.conf: spice_tls=1.
Current revision of multipath.conf detected, preserving
< /code >

I set 'auth_tcp = "sasl"' (in "/etc/libvirtd.conf") and 'spice_tls=1' (in
"/etc/libvirt/qemu.conf") and restart vdsdmd.service, but it still fails:

I've no idea about how to investigate, solve or troubleshoot this issue.

I've updated yesterday to the last version but nothing changed:
ovirt-release-master-4.3.0-0.1.master.20180820000052.gitdd598f0.el7.noarch
= /Issue questions =

I think that this one can help : https://www.ovirt.org/develop/developer-guide/vdsm/installing-vdsm-from-rpm/#installing--configuring-vdsm

Make sure you've installed libvirt from the rpm as appeared on the link there.
