[ovirt-users] Re: oVirt API - New vm on specified storage
Hi Tommaso,
I don't have much experience with API, but let me ask differently: Have you
tried using oVirt Ansible modules
<https://docs.ansible.com/ansible/latest/modules/list_of_cloud_modules.html#ovirt>
to achieve your goal? It's really easy to create a vm with ovirt_vm
<https://docs.ansible.com/ansible/latest/modules/ovirt_vm_module.html#ovirt-vm-module>
and oVirt engine already includes all the requirements for that.

[ovirt-users] Re: API OVA export - getting job id/job status
Hi Lars, you might find this email thread interesting:
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/PXYAQ7YEBQCUWCAQCFAFXB3545LNB23X/
Jayme is trying to solve pretty much the same problem as you - although
he's using the Ansible approach instead of SDK. Feel free to join that
conversation. At this point it seems like he might have found a good
solution, but he needs to test it.

[ovirt-users] Re: ovirt_vm ansible module -- how to wait for ova export to finish
Hi Jayme,
let us know how it went. Anyway, if you ever run into hard timeout, don't
despair. It also happened to me once when working with Ansible oVirt
modules and I just created an issue on GitHub where I requested this
timeout to be changed from hard-coded value to a configurable parameter
with some reasonable default. It was implemented rather quickly.

[ovirt-users] Re: ovirt_vm ansible module -- how to wait for ova export to finish
Hi Jayme,
here's my idea. I haven't tested it but I believe it should work.
1. Create a new task file (let's call it export_vm.yaml) and include two
tasks in there:
1.1. First task uses ovirt_vm module (pretty much what you already have) to
export VM
1.2. Second task uses wait_for
<https://docs.ansible.com/ansible/latest/modules/wait_for_module.html>
module (specifically its path parameter) to wait until the OVA file in
/backup exists
2. Loop over those two tasks as explained here
<https://ericsysmin.com/2019/06/20/how-to-loop-blocks-of-code-in-ansible/>.
Hope this helps.

[ovirt-users] Re: ovirt_disk Ansible module creating disks of wrong size but why?
Maybe it's just what Lucie mentioned - that we cannot really resize the original disk size of CentOS image. I think workaround for that would be using the original QCOW image as boot disk for OS and then creating a new disk for data of whatever size you want it to be.

[ovirt-users] Re: Ansible example for creating VM from qcow2 image?
Hello,
creating a VM with QCOW2 disk is as easy as that. The only requirement to
run this is having QCOW2 disk named "centos7" in your engine:
---
- hosts: localhost
gather_facts: false
tasks:
- name: Obtain SSO token
ovirt_auth:
url: https:///ovirt-engine/api
username: admin@internal
password:
- name: Create a VM with QCOW2 disk
ovirt_vm:
auth: "{{ ovirt_auth }}"
state: present
cluster: Default
name: jzmeskal_centos7
disks:
- name: centos7
bootable: True
Now if you'd like to use cloud-init, that's a different story and you
probably won't get around using templates. From the Ansible point of view,
it's quite easy - you just use *cloud_init* key of *ovirt_vm* module.
However for that to work, your VM has to be either created with a disk that
has *cloud-init *package installed or created from a template that is
cloud-init enabled. See my response from December here
<https://lists.ovirt.org/archives/list/users@ovirt.org/message/VD2DREZYMDY2NE5LKNS6OBFE36PC66R7/>
. Another user was interested in pretty much the same topic.
Hope this helps!

[ovirt-users] Re: Confusion about storage domain ISO. How do I provision VMs?
Hi, I'm glad you could figure it out in the end. It's true that the message "Paused by System" isn't super useful when trying to figure out what's wrong. It would definitely be worth to submit a bug requesting more descriptive error message. Since you already have an environment that reproduces the issue, would you please consider reporting the bug here <https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt-engine>? Thank you for reaching out to the mailing list and sharing the solution!

[ovirt-users] Re: Confusion about storage domain ISO. How do I provision VMs?
Hello, I'll do my best to help you with that but first let's look closely into your situation. Specifically I have two questions: 1) What exactly was the issue when you tried to upload the ISO to data domain? I've just tried that on oVirt 4.3.7 and has no problem with it. 2) Can you double check that you've got the right cloud image? As far as I know cloud images are usually provided in QCOW2 format, like here: https://cloud.centos.org/centos/7/images/ Do you *need* to use ISO files at all?

[ovirt-users] Re: oVirt and Containers
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/configuring_for_rhv.html 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!

[ovirt-users] Re: oVirt and Containers
Hi Robert, there are different answers based on what you mean by integrating oVirt and containers. Do you mean: - Installing container management (Kubernetes or OpenShift) on top of oVirt and using oVirt as infrastructure? - Managing containers from oVirt interface? - Running VM workloads inside containers? - Something different? I can elaborate more based on your specific needs Best regards Jan On Tue, Dec 24, 2019 at 3:52 PM Robert Webb wrote: > I was searching around to try and figure out the best way to integrate > oVirt and containers. > > > > I have found some sites that discuss it but all of them are like 2017 and > older. > > > > Any recommendations? > > > > Just build VM’s to host containers or is there some direct integration? > > > > Here are a couple of the old sites > > > > https://fromanirh.github.io/containers-in-ovirt.html > > > > > https://kubernetes.io/docs/setup/production-environment/on-premises-vm/ovirt/ > > > > > https://www.ovirt.org/develop/release-management/features/integration/container-support.html > ___ > Users mailing list -- users@ovirt.org > To unsubscribe send an email to users-le...@ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/7BIW2Z3ILBSAGQ4F7QB3MPEUWVW4GUUN/ > -- Jan Zmeskal Quality Engineer, RHV Core System Red Hat <https://www.redhat.com> <https://www.redhat.com> ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/55D5JA2FMPHUJAAK4ADGTKCPPMYOVAEP/
[ovirt-users] Re: Strategy to Mange Ovirt VMs Created from Templates
Hi Jeremy, I found an old blog post where the author seals the VM manually, see here: https://www.linuxtechi.com/create-vm-template-ovirt-environment/ Please, *do not follow this guide* since it seems to be a bit outdated. Nonetheless, it might give you a more specific idea about what sealing the template (which is done for you by oVirt) actually entails.

[ovirt-users] Re: List VMS with ansible version 2.9 ovirt_vms_info module
Hello, I think it's just a typo. Try renaming "ovirt_vms_facts" to
"ovirt_vm_facts". This worked for me:
- hosts: localhost
gather_facts: no
tasks:
- name: Login to oVirt
ovirt_auth:
url: https:///ovirt-engine/api
username: admin@internal
password:
insecure: yes
- name: Gather info on all the virtual machines
ovirt_vm_facts:
auth: "{{ ovirt_auth }}"
pattern: "cluster=Default" # Get VMs from cluster "Default"
- name: Print the gathered info
debug:
var: ovirt_vms
Or better yet, use directly "ovirt_vm_info" like this. Note that when using
"ovirt_vm_info", you need to *register* the output in a variable.
- hosts: localhost
gather_facts: no
tasks:
- name: Login to oVirt
ovirt_auth:
url: https:///ovirt-engine/api
username: admin@internal
password:
insecure: yes
- name: Gather info on all the virtual machines
ovirt_vm_info:
auth: "{{ ovirt_auth }}"
pattern: "cluster=Default" # Get VMs from cluster "Default"
register: vms
- name: Print the gathered info
debug:
var: vms.ovirt_vms
I believe that not being able to see documentation for "ovirt_vm_facts" in
*ansible-doc* command is an intention.
Best regards
