Upgrade question
by Alan Murrell 09 Nov '14

09 Nov '14

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! :-) -Alan

I want to switch back to local storage

------=_Part_2357_378790510.1415517080365 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit 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 ?

how to 'reset' a failed install?
by Robert Story 08 Nov '14

08 Nov '14

--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?

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, Koen

Add multiple files to a VM via cloud-init
by Branimir Pejakovic 07 Nov '14

07 Nov '14

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
