by femi adegoke 25 May '18

This is oVirt 4.2.3 + Gluster. I ran yum -y update on the hosted engine. It installed 1 package & upgraded 16. Is it necessary to run "engine-setup" again after the yum update?

oVirt 4.2 host actions dropdown truncated

example of full list in oVirt 4.2.3.5 with only one host https://drive.google.com/file/d/12fj3uorno9UjBL_aNQOG0mUSqEFn-Ol4/view?usp=… example of truncated list in oVirt 4.2.3.7 with 3 hosts https://drive.google.com/file/d/1Es3YSAhcB_L-feaHdkAvwZz8BTB3sYiS/view?usp=… if I select with the mouse into the column and then scroll with mouse, I can see also the items below in the list: STOP, SSH MANAGEMENT, ecc. but all in all it seems counter-intuitive to me... I think the .5 vs the .7 in version is not the culprit. Anyone can reproduce? BTW: I reproduced the same strange behavior also in an RHV environment with latest 4.2 (updated yesterday), with two hosts. Any comments? Gianluca

Support for openstack keystone v3 API?
by Bernhard Dick 24 May '18

24 May '18

Hi, I wanted to try ceph with oVirt and so I've installed an openstack queens (current stable) environment containing cinder and keystone. But when I tried to add the storage provider I ended up with 404 errors in the engine log files. They are because oVirt tries using the v2.0 API, and http://HOST:5000/v2.0/tokens does not exist. If I understand the release notes of openstack correctly the section https://blueprints.launchpad.net/keystone/+spec/removed-as-of-queens includes all v2.0 API being removed from keystone. So I'm asking whether there is support for the v3 API in sight? Regards Bernhard

Error setting cluster level to 4.2
by Gianluca Cecchi 24 May '18

24 May '18

Hello, after upgrading engine (external) and the 3 hosts composing the cluster, I try to set its level to 4.2 but I receive this kind of message " Error while executing action: Update of cluster compatibility version failed because there are VMs/Templates [ov42, ovlive3, ovlive4, ovlive1, ovlive2] with incorrect configuration. To fix the issue, please go to each of them, edit, change the Custom Compatibility Version of the VM/Template to the cluster level you want to update the cluster to and press OK. If the save does not pass, fix the dialog validation. After successful cluster update, you can revert your Custom Compatibility Version change. " The ovliveN VMs are diskless where I boto from the oVirt live iso for testing and ov42 a nested single VM where I tested the oVirt 4.2 environment before upgrade of the real cluster. I suspect that the problem could be related with macspoof custom property set to true. Is this? In case how can I manage this sort of problem? Can't I have macspoof in 4.2? Thanks, Gianluca

Need advice using pacemaker on VMs for application HA
by wodel youchi 24 May '18

24 May '18

Hi, Excuse the English :) Need some advice regarding the use of high availability software on VMs on oVirt. We are migrating a physical high available application to oVirt. The HA platform uses pacemaker, it contains two nodes and a shared storage, fence (stonith) is configured to use ILO. I know that oVirt offers HA for VM, but this HA is not application aware, if a service crashes on the VM, it will not be detected. Fencing could be achieved by fence agent rhev. My questions are about the best way to migrate this platform to oVirt. - Is it a good idea to make both VMs (formally nodes) Highly-Available VMs? or may be pin each one of them to a particular hypervisor and/or use VM-Affinity? - I am thinking about the situation where the hypervisor containing one of the VMs crashes, what will be the behavior of the the fence agent on the application? - if the crashed VM is not HA, it will not start on another hypervisor, so the fence agent will try to fence a VM that does not exist anymore, and it will stuck. - if the crashed VM is HA, it will be started on another hypervisor, but what will happen with the fence agent? I think that one VM will fence the other one, and the application will still be unreachable for a longer period. - What about the shared storage, we will use a shared disk on oVirt which does not support snapshot - What are the things to avoid? Any suggestions will be appreciated. Regards.

Ovirt 4.2.3 missing features?
by Guilhem Berna 24 May '18

24 May '18

Hi, New user of ovirt here, i'm trying ovirt 4.2.3.5-1 on centos 7.5. On the web administration interface i'm missing a lot of features compared to the guides I can find online or even compared to the official docs. For example I can't find how to restore a snapshot, I don't have the snapshot tab as mentionned here : [ https://www.ovirt.org/documentation/user-guide/user-guide/#using-a-snapshot… | https://www.ovirt.org/documentation/user-guide/user-guide/#using-a-snapshot… ] I can't find how to convert a machine to a template either : Is there something i'm missing? Am I running the wrong version or do I need to configure something ? Best regards, [ https://www.ovirt.org/documentation/user-guide/user-guide/#using-a-snapshot… | 4.2.3 ] Guilhem Berna Sysadmin PHOSPHORE.si - [ https://www.phosphore.si/ | https://www.phosphore.si ]
