what is "use host" field in storage domain creation??

hello and happy new year~ I am wondering the role of "use host" field in storage domain creation. https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storage.… above link says all communication to the storage domain is through "use host". but I can't understand inefficiently passing through that "use host" even though every host can directly access to all domains. it seems like i am misunderstanding something.

Cannot add Foreman as a provider
by Robert Webb 29 Dec '19

29 Dec '19

So I just setup a brand new Foreman instance and have been trying to get it setup with oVirt. I was able to install the oVirt plugins under Foreman and have the oVirt engine setup as a computer resource. Where I am running into an issue is adding Foreman as an additional provider under oVirt. In the log I get: Command 'org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand' failed: EngineException: https://foreman.saroza-webb.internal:443/api/v2/discovered_hosts?format=jso… (Failed with error PROVIDER_FAILURE and code 5050) I have done some searching, but everything I have found seems to be from years ago and deals with oVirt 3.5.x Any thoughts?

Metrics
by gregory.day＠target.com 29 Dec '19

29 Dec '19

Hello. I'm trying to deploy the metrics store and the ansible run fails at "TASK [/usr/share/ansible/roles/oVirt.metrics/roles/oVirt.origin-on-ovirt : Collect oVirt VM facts]" I've tried adding the -vvv and ANSIBLE_DEBUG=1, but that isn't giving me any additional information on why it is failing. fatal: [localhost]: FAILED! => { "attempts": 5, "censored": "the output has been hidden due to the fact that 'no_log: true' was specified for this result", "changed": false } When I edit the playbook and set no_log: true, the output is shown, but the resulting log shows that the "ansible_facts.ovirt_vms[0].fqdn" dictionary key does not exist. What is the best way to work around this issue? Thanks, Greg

No virtio-win vfd oVirt 4.3.7
by Vrgotic, Marko 27 Dec '19

Dear oVIrt, I am trying to install Windows 10 on oVirt, following procedure on: https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Windows_Virtu… Unfortunately, there is no option as explained in the “Installing Windows on VirtIO-Optimized Hardware”. There is just no “virtio-win.vfd” option when attaching Floppy. Is this valid. I have ISO Domain, which is not hosted by Hosted Engine, but mounte additionally. Is this required in order to have the virtio-win.vfd option? If not, please let me know what am I missing. In the meanwhile, I am working on building custom Wind 10 ISO which contains Virtio/Virtio-SCSI drivers.

ovirt-host 4.4.0 Task Update system failed to execute - Running QEMU processes found, cannot upgrade Vdsm
by alexandermurashkin＠msn.com 27 Dec '19

27 Dec '19

On a regular basis, there is "Task Update system failed to execute" error in the engine.log. At the same time, the ovirt-host-mgmt-ansible-check log contains "Running QEMU processes found, cannot upgrade Vdsm" error. Is there some configuration setting that controls it? Why oVirt is trying to update ovirt-host package on the host at all if there are virtual machines running?

I had a crash yesterday in my ovirt cluster,I just tried to add a new network，Which migration Policy do you recommend?
by zhouhao＠vip.friendtimes.net 27 Dec '19

27 Dec '19

I had a crash yesterday in my ovirt cluster, which is made up of 3 nodes. I just tried to add a new network, but the whole cluster crashed I added a new network to my cluster, but while I was debugging the newswitch, when the switch was poweroff, the node detected the network card status down and then moved to Non-Operational state. At this time all of 3 nodes moved to Non-Operational state. All virtual machines have started automatic migration,When I received the alert email, all virtual machines were suspended In 15 minutes my newswitch were power up again.The 3 ovirt-nodes become active again, but many virtual machines become unresponsive or suspended due to forced migration, and only a few virtual machines are pulled up again due to cancelled migration After I tried to terminate the migration tasks and restart ovirt-engine service, I was still unable to restore most of the virtual machines, so I had to restart 3 ovirt-nodes to restore my virtual machine I didn't recover all the virtual machines until an hour later Then I modify my migration policy to " Do Not Migrate Virtual Machines" Which migration Policy do you recommend? I'm afraid to use cluster... zhouhao(a)vip.friendtimes.net

Re: oVirt and Containers
by Jan Zmeskal 26 Dec '19

Okay, so this topic is quite vast, but I believe I can at the very least give you a few pointers and maybe others might chime in as well. Firstly, there's the Kubevirt project. It enables you to manage both application containers and virtual machines workloads (that cannot be easily containerized) in a shared environment. Another benefit is getting advantages of the powerful Kubernetes scheduler. I myself am not too familiar with Kubevirt, so I can only offer this high-level overview. More info here: https://kubevirt.io/ Then there is another approach which I am more familiar with. You might want to use oVirt as an infrastructure layer on top of which you run containerized workflow. This is achieved by deploying either OpenShift <https://www.openshift.com/> or the upstream project OKD <https://www.okd.io/> in the oVirt virtual machines. In that scenario, oVirt VMs are considered by OpenShift as compute resources and are used for scheduling containers. There are some advantages to this setup and two come into mind. Firstly, you can scale such OpenShift cluster up or down by adding/removing oVirt VMs according to your needs. Secondly, you don't need to set up all of this yourself. For OpenShift 3, Red Hat provides detailed guide on how to go about this. Part of that guide are Ansible playbooks that automate the deployment for you as long as you provide required variables. More info here: https://docs.openshift.com/container-platform/3.11/install_config/configuri… When it comes to OpenShift 4, there are two types of deployment. There's UPI - user provisioned infrastructure. In that scenario, you prepare all the resources for OpenShift 4 beforehand and deploy it in that existing environment. And there's also IPI - installer provisioned infrastructure. This means that you just give the installer access to your environment (e.g. AWS public cloud) and the installer provisions resources for itself based on recommendations and best practices. At this point, neither UPI nor IPI is supported for oVirt. However there is a GitHub repository <https://github.com/sa-ne/openshift4-rhv-upi> that can guide you through UPI installation on oVirt and also provides automation playbooks for that. I have personally followed the steps from the repository and deployed OpenShift 4.2 on top of oVirt without any major issues. As far as I remember, I might have needed occasional variable here and there but the process worked. Hope this helps!

Overt-Engine Down | Host Unresponsive
by Vijay Sachdeva 26 Dec '19

26 Dec '19

Dear Team, I have one question, if Ovirt-engine goes down for some reason. Will it impact my host to go un-responsive and all VMs down? I just faced a situation where my host was in un-responsive status and all VMs were down. I restart the ovirt-engine service and host got activated. Can anyone let me know this situation? Thanks Vijay Sachdeva
