OKD / Openshift under oVirt
by michael＠wanderingmad.com 10 Mar '19

10 Mar '19

I have ovirt currently running with 3 hyper-converged nodes, and loving it. I've had some issues with kubernetes and would prefer to try out openshift / OKD, but the trick is i'd like to do it in a fault-tolerant way, with a load balancer, 2 masters and 3 works, but I can't seem to find a good way to do it, is there anyone that can offer help? I tried using what was posted to the blog, but it was a single-node install and was never updated with part 2.

Timestamp offset in engine.log
by Ian Fraser 09 Mar '19

09 Mar '19

Hello, I am trying to follow the instructions for installing the metrics store and a prerequisite is ensuring the timestamps in /var/log/ovirt- engine/engine.log include a UTC offset (at bottom of this page: https://www.ovirt.org/documentation/metrics-install-guide/Introduction.html ). Mine currently do not (i.e. they look like "2019-03-07 14:14:23,223Z"). "timedatectl | grep -i 'time zone'" shows "Time zone: Europe/London (GMT, +0000)" Can anyone please tell me how to change this timestamp format to statisfy this prerequisite?

You can change the MTU in the network config in oVirt engine. The management portal. Go to clusters then networks or something like that. You can then modify the MTU. MTU can also be set manually in network scripts on the host but you need to define this in the engine. At least this is how I got Infiniband working. I can send screenshots on Monday.

oVirt 4.3 and AMD Opteron G3 CPU
by Jiří Sléžka 08 Mar '19

08 Mar '19

Hi, I know, old AMD Opterons G3 are unsupported in oVirt 4.3 but anyway, is there a way to switch cluster to 4.3 mode with these old CPUs? On the other hand 4.2 mode is no problem, I just would like to test new stuff (on legacy hw ;-) Cheers, Jiri Slezka

Re: oVirt Performance (Horrific)
by Strahil 08 Mar '19

08 Mar '19

Hi Drew, During my tests on gluster v3, using 'disable.nfs: false' and using that as ovirt storage brought maximum performance for my 1 Gbit/s network. Can you try using NFS and if it works well, you can disable nfs and get NFS Ganesha up and running. It seems that FUSE in gluster v5 is performing way better, but still it is not the optimal solution. Best Regards, Strahil Nikolov

LUN ID Change on Storage Domain
by Alan G 08 Mar '19

08 Mar '19

Hi, I made an error when provisioning a new FC storage domain and gave it LUN ID 0 by mistake. I now need to move it to another ID. Can I do this: - 1. Shutdown all VMs on the domain. 2. Put the domain in maintenance. 3. Change the LUN ID. 4. Force SCSI rescan on every host. 5. Bring the domain out of maintenance. Will oVIrt still recognise the domain on a different LUN ID? Thanks, Alan

When you create the new network, can't you set the MTU also? I know that UI allows changing MTU, but never checked if it can be set during definition. Best Regards, Strahil Nikolov

Infiniband Usage / Support
by Andrey Rusakov 08 Mar '19

08 Mar '19

Hi, I got a config with IB Storage (IPoIB). I would like to extend IB usage to OVN network, but trying to do this i find some problems ... Problem #1 (IPoIB Storage Network) I configure IPoIB Before adding to oVirt cluster (I did it using Cockpit) Create [Bond], assign IP, change MTU. At this moment of time everything is fine... But - I am not able to assign IP/MTU using oVirt Cluster. And I can't perform any changes using Cockpit as IB interfaces are "Unmanaged Interfaces". Problem #1.1 It will be great to avoid users adding IPoIB networks using brctl, as it will not work... Problem #2 What is correct way to move OVN to IPoIB network?

Info about firewall type and 4.3
by Gianluca Cecchi 08 Mar '19

08 Mar '19

Hello, I have updated a 4.2.8 environment to 4.3.1 So far so good, I have updated cluster level and dc level from 4.2 to 4.3 I notice the field "Firewall type" in my cluster and it is currently set to "iptables". My 3 hosts are CentOS 7.6 plain servers. My external engine is CentOS 7.6 and already with firewalld I seem to remember in the long run only firewalld supported also on hosts. Is this correct and in case is there an ETA/version? What would be the steps to pass my current hosts to firewalld in case? Currently I see: iptables enabled and running ip6tables disabled ebtables disabled Thanks in advance, Gianluca

Re: Two Hosts with Self Hosted Engine - HA / Failover & NFS
by Strahil 07 Mar '19

07 Mar '19

I don't think that you can achieve it with only 2 nodes, as you can't protect yourself of split brain. Ovirt supports only glusterfs of replica 3 arbiter 1. If you create your own glusterfs , you can use glusterd2 with a "remote arbiter" in another location. That will give you protection from split brain and as it is remote - the latency won't kill your write speed. I can recommend you to get a VM in your environment (not hosted on any of the 2 hosts) or a small machine with a SSD and use that as pure arbiter. Using one of the 2 nodes as arbiter brick is not going to help, as when that node fails - the cluster on the other node will stop working. It's the same with hosting NFS on one of the machines. As far as I know DRBD is not yet fully integrated, but you can give it a try.Still, using only 2 nodes gives no protection from split brain.

Please don't remove instance type
by Baptiste Agasse 07 Mar '19

07 Mar '19

Hi all, We are happy oVirt users for some years now (we started with 3.6, now on 4.2) and we manage most of our virtualization stacks with it. To provision and manage our machines, we use the foreman (for bare metal and virtual machines) on top of it. I made some little contributions to the foreman and other underlying stuff to have a deeper integration with oVirt, like to be able to select instance type directly from foreman interface/api and we rely on it. We use instance types to standardize our vms by defining system resources (memory, cpu and cpu topology) console type, boot options. On top of that we plan to use templates to apply OS (CentOS 7 and CentOS 6 actually). Having resources definitions separated from OS installation help us to keep instance types and templates lists small and don't bother users about some technical underlying stuff. As we are interested in automating oVirt maintenance tasks and configuration with ansible, I asked at FOSDEM oVirt booth if there is any ansible module to manage instance types in Ovirt as I didn't find it in ovirt ansible infra repo. The person to whom I asked the question said that you are planning to remove instance types from ovirt, and this make me sad :(. So here I am to ask why do you plan to remove instance types from oVirt. As far as I know, it's fairly common to have "instance types" / "flavors" / "sizes" on one side and then templates (bare OS, preinstalled appliances...) on other side and pick one of each to make an instance. If this first part is missing in future version of ovirt, it will be a pain point for us. So, my question is, do you really plan to remove instances type definitely ? Cheers. -- Baptiste

Two Hosts with Self Hosted Engine - HA / Failover & NFS

If so, can anybody point me to any docs or examples on exactly how the Storage setup is done so that NFS will replicate across the hosts? If not what file system should I use to achieve this?

Quota Actual Consumption
by Andrey Rusakov 06 Mar '19

06 Mar '19

Hi, Is it possible to configure oVirt to work Quota with actual vCPU Consumption. Currently i got 1 VM with 2 vCPU and 8Gb. In VM stats - 0% of CPU in use 0% of RAM in Use (it is fresh Linux instalaltion) In Quota consumption i can see 40% of CPU (vCPU quota = 5) 27% of RAM (Memory quota 30Gb) Is it possible to adjust Quata management to work with Actual workload, instead of VM Configuration? P.S. Seems like it is working for Storage, as i can see 0% Consumption in Quota (1Gb of thick disk with 20Gb Max and 200Gb in Quota)

OVN Deployment
by Bryan Sockel 06 Mar '19

06 Mar '19

Hi, I am looking to implement OVN with in my setup, but could use some guidance on the implementation. As part of the implementation i am planning on moving from engine being installed on a physical server to running as a VM with in my environment. I do not need to retain any historical data. The plan would be to import the vm's into a new deployment of oVirt after getting everything setup. Currently i have a single host i plan on using for the initial deployment, but as vm's are moved over, i will be adding additional hosts. With the deployment of oVirt 4.3.x the ovn provider is installed correctly. Is there a problem with installing the OVN Controller on the Hosted Engine? Has any one found a good guide for setting up and deploying ovn in an oVirt hosted-engine environment? Thank You, Bryan Sockel
