Upgrade question
by Alan Murrell
Hello,
I just wanted to clarify the upgrade procedure for when I am ready to go
from my 3.4 -> 3.5.
I have a single server running oVirt 3.4 (host+storage) with a
self-hosted engine setup. The hosted engine and the host are both on
CentOS 6.5.
According to the release notes for 3.5, I would install the
ovirt-release35.rpm RPM, which gives me the oVirt 3.5 repositories. Is
the upgrade path at that point then as simple as running "yum upgrade"
on both the host and the hosted-engine or do I still need to run "yum
update ovirt-engine-setup" then "engine-setup" after upgrading both?
It isn't clear (to me) if the "yum ovirt-engine-setup" and
"engine-setup" steps on the 3.5 Release Notes are for a clean install
only, or if they still need to be run on a system being upgraded.
Thanks! :-)

I want to switch back to local storage
by Demeter Tibor
------=_Part_2357_378790510.1415517080365
Content-Type: text/plain; charset=utf-8

Hello,
At last night I have sussessfully migrated my vms from kvm to gluster based ovirt 3.5.
It sounds good, but the results was terrible: The glusterfs (two node replicated) is too slow for our vms. It is a very big problem, so I have looking for soultion.
I don't know why but glusterfsd now uses 500-800% of my cpus on each server.
At this moment I have only one gluster volume for vms.
I just wondering I will configure local storage on the second host and copy to all of vms from glusterfs to this volume.
I know in this case the second host will be on a different Datacenter. But in this case what will happend with my glusterfs? It will be break it? Will I lost my data? Could it make split-brains on gluster?
It will break the whole ovirt-portal?
If possible I don't want to more downtime by this procedure.
It is possible?
My config:
2 node dell r710, raid5 , 3xbonded 1GBs NICs + one for internet access for vms. The glusterfs uses same network with ovirtmgmt.
What can I do ?
Thanks in advance
Tibor

how to 'reset' a failed install?
by Robert Story
--Sig_/XgT780OOyzGFn25W/6Ar8P0
Content-Type: text/plain; charset=US-ASCII
Content-Transfer-Encoding: quoted-printable
I've been doing lots of unsuccessful 3.5 hosted-engine installs in my lab,
where it's easy for me to re-install the OS if I need to start over. Now I
need to try an install in a remote datacenter where I won't be able to
re-install the OS. So I was wondering if there is a way to 'reset' a failed
install so that another install can be attempted...
My thoughts so far are:
- stop vdsm, supervdsm, and libvirt
- use etckeeper to reset everything under /etc
- delete old log files
- delete hosted_engine storage domain on storage (if install got that far)
- restart vdsm, supervdsm, and libvirt
What am I missing? Maybe some remnants in /var (hmm, probably the vdsm
persistent config)? Anything else?

webhook
by Koen Vanoppen
Hi all,
Just a quick question. Is it possible to set a webhook on the removal and
creation of a new vm? So we can send to foreman a delete action when the VM
is deleted...
Kind regards,

Add multiple files to a VM via cloud-init
by Branimir Pejakovic
Hi list,
I was wondering is there a way to add multiple files to a vm via cloud-init
using python SDK. I was able to add /etc/resolv.conf and additionally I
would like to add config files for NICs (ifcfg-ethX) with appropriate
values (ip,gw,netmask). I used an example given here:
http://www.ovirt.org/Features/Cloud-Init_Integration . But unfortunately I
cannot do the same thing If I want to write multiple files to a vm in
params.Action class.
Thank you in advance!
Best regards,
Branimir
