[Users] Centos 6.5 host configuration script -- a tale begun

--_000_22f073c8f28e423a8959bb2687b19cb9DM2PR05MB320namprd05pro_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable I have been working since Monday to get a Centos 6.5 host node added to ovi= rt. Since 6.5 is just out, I figured I might as well use the latest and gr= eatest to build my host. Today I succeeded (I think). I have not actually= added a VM to the host, but at least ovirt is willing to accept that the h= ost is part of the default cluster. My next task will be bringing up glust= er on that same node. Since I will be doing at least three more hosts, I wrote a shell script to = do a the setup that is needed to make the ovirt process succeed. No, I do not have a similar script for the engine. I got that running unde= r Centos 6.4 in a VM, without too much problem. That VM is temporarily run= ning on a KVM host (but that host is not under ovirt). Feel welcome to stare at or run my script and make any comments or observat= ions. * The script is run after a clean install of Centos 6.5 from the "minim= al" ISO. * I will try to remember what each element was there for, if anything i= s not clear. * There are probably a few (not many) things there that are not needed * Mostly they result in doing something ahead of time that ovirt was= going to do later anyway. * Feel free to point out a better way to do whatever needs to be done. * Bits and pieces of the script were stolen from googleing here and the= re. * Parts of the script were cooked up by stewing logs over low heat unti= l something useful bubbled to the top. * The number of clean reinstalls to test the script is beyond count. * I almost broke down and learned how to write a kickstart file (but= didn't). * No guarantees or representations. * So far this script has been tested on exactly one set of bare-meta= l hardware * That hardware is not server-grade. (ovirt keeps complaining bec= ause I have not configured Power Management :) * There are a few things that are personal preferences (things I instal= l on all my Linux machines) * I believe those preferences are clearly marked. * I am leaving them in because they may (incidentally) be installing= some dependencies that influence the outcome of the process. I hope to see a day when a similar script is either not needed, or is avail= able and maintained as part of the Centos distro, or as part of ovirt. Mea= nwhile we try to muddle through. I will copy my script into this webmail interface (OWA) (since I am writing= at home and this is all I have to work with) and see how bad it mangles it= . You'll probably need a wide window so that lines don't wrap, as Microsof= t thinks this OWA interface doesn't ever need to let me specify text as "pr= eformat".

[Users] Map disk UUID to guest or disk name?
by Blaster 01 Jan '14

01 Jan '14

On an Ovirt datastore the disk image names for the guests are named with an unfriendly UUID name. Is there any way to map that back to the human readable name given int the GUI? It would be nice if this name was dropped in as a field in the .meta file. I see there is a DESCRIPTION= field, but it’s blank. I tried updating the description in the GUI, but it’s still blank (bug, or do I have to update something? I tried deact/activate the disk and it still didn’t update…)

[Users] VM payload
by René Koch (ovido) 01 Jan '14

01 Jan '14

Hi, I created a vdsm hook script for passing payload information (vm name) to a virtual machine, which is placed in before_vm_start folder on my hypervisor (CentOS 6.5). If I create a new virtual machine out of a template some strange things happen: When starting the vm the first time I can see that the vdsm script is executed, but no additional cd drive is shown in this vm. But after shutting down the vm and powering on again, the cd drive appears. Here's the vdsm hook I use: https://raw.github.com/ovido/ovirt-stuff/master/hooks/50_payload I don't really get why the payload isn't working when starting a vm the first time. This happen on oVirt 3.2 and 3.3. Thanks a lot for help! -- Best Regards René Koch Senior Solution Architect ============================================ ovido gmbh - "open source solutions" Brünner Straße 163, A-1210 Vienna Phone: +43 720 / 530 670 Mobile: +43 660 / 512 21 31 E-Mail: r.koch(a)ovido.at ============================================

[Users] recommandations for saving backing up ovirt

This is a multi-part message in MIME format. --------------080409070709050803070307 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Hi all, I 'd like to receive any usefull advices from the community about good practice of backing up ovirt with the restraint of zero down time. This involves : * saving vms without shutting down (Restoring them can be done with a halt). Is live snapshot enough for this? Is lvm or san snapshot recommended? * saving the postgres database (or only some of main tables). Can we do it without stopping engine and the risk of a data corruption? Is there a howto?

Hello all, First of all thank you for your help, I've finally managed to get my Cluster configured properly but now that I create VMs I'm facing another problem. Whenever I start my VM I get this error. "VM TestVm is down. Exit message: Child quit during startup handshake: Input/output error." I've googled around but haven't found any satisfactory solution. If anyone can help out it would be great. Regards Nauman Abbas Assistant System Administrator (LMS), Room No. A-207, SEECS, National University of Sciences & Technology, + 92 321 5359946
