Import VM from VMware OVA
by Hari Prasanth Loganathan 23 Oct '18

23 Oct '18

Hi Team, 1) I exported a ovf file from VMware 2) I converted the ovf file to ova using ovftool successfully. 3) I imported the ova using the VM Import -> VMware appliance OVA -> provided the path of the ova (copied in ovirt location) 4) VM is successfully imported into the ovirt and I see the disk is also successfully imported BUT the disk is stored as image disk, What is the possible way to import the VM (as mentioned above) and store the disk as Cinder disk (currently always it is storing as image disk type) Any help is much appreciated.

cloud-init behaviour after reboot and growpart
by Nathanaël Blanchet 23 Oct '18

23 Oct '18

Hi all, After having successfully run cloud-init with the "initial run" box checked, I meet an issue after rebooting the el7 vm. At the boot time, cloud-init waits for a data source that doesn't exist anymore and I have to wait serveral timeouts like this one: open 'http://169.254.169.254/openstack' with {'url': 'http://169.254.169.254/openstack', 'headers': {'User-Agent': 'Cloud-Init/0.7.9'}, 'allow_redirects': True, 'method': 'GET', 'timeout': 10.0} configuration As a workaround, I must include in the initial custom script "touch /etc/cloud/cloud-init.disabled" so as to the vm to boot properly. Now I'd like cloud-init not to be fully disabled because I need it resizes the filesystem after the growpart step. Can anyone help me with this? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

OpenStack Block Storage Provider without authentication doesn't work
by Matthias Leopold 23 Oct '18

23 Oct '18

Hi, we're successfully using Cinder as a Block Storage Provider for oVirt with customized Cinder installation in a CentOS host according to OpenStack docs. Now i wanted to try out running Cinder in Docker and followed the instructions from https://thenewstack.io/deploying-cinder-stand-alone-storage-service/ (customized for use with Ceph RBD). This works to the point where i can setup an external provider and consequently a storage domain in oVirt. I set up the provider without authentication and testing this (by pressing "Test" button) works. When i want to create disks i realize that oVirt doesn't recognize the "Volume Type" definitions. In engine.log i see messages like 2018-10-03 12:04:46,990+02 ERROR [org.ovirt.engine.core.bll.storage.disk.cinder.GetCinderVolumeTypesByStorageDomainIdQuery] (default task-72) [06d4fbf7-0b3c-46b3-8166-148ee7f67a4c] Query 'GetCinderVolumeTypesByStorageDomainIdQuery' failed: null 2018-10-03 12:04:46,990+02 ERROR [org.ovirt.engine.core.bll.storage.disk.cinder.GetCinderVolumeTypesByStorageDomainIdQuery] (default task-72) [06d4fbf7-0b3c-46b3-8166-148ee7f67a4c] Exception: java.lang.NullPointerException I very much suspect that not using authentication (because of "auth_strategy = noauth" in cinder.conf) is the culprit. Listing types with cinder CLI from the engine host works (when using the appropriate environment). Can some of the RH devs confirm this behaviour? Is this an engine bug? thanks Matthias

re-enabling networkmanager
by fsoyer 23 Oct '18

23 Oct '18

Hi, I have installed a 4.2 cluster on CentOS 7 nodes but I have follow an (old) procedure of mine done with 4.0 : so, I have disabled Network Manager before installing oVirt. The networks created and validated in the engine UI are : ovirmgmt on bond0 (2 slaves) failover mode storagemanager on bond1 (2 slaves), jumbo frames, aggregation mode, serving Gluster. Today, I installed Cockpit on the node to have the nodes consoles. But it say that it cannot manage the network without NM. So my question is : is there any risk to re-enabled NM on the nodes ? Can it broke anything done by the UI ? -- Cordialement, Frank Soyer Mob. 06 72 28 38 53 - Fix. 05 49 50 52 34 Systea IG Administration systèmes, réseaux et bases de données www.systea.net Membre du réseau Les Professionnels du Numérique KoGite Hébergement de proximité www.kogite.fr

PythonSDK 4.2.8 issues updating cdrom iso of a vm.
by Brad Riemann 22 Oct '18

22 Oct '18

Hello, I am currently fighting with attaching an iso to a vm's cdrom. There are two isos in the iso domain (A-Iso-Installer.iso and The-Iso-Installer.iso for our purposes), I can confirm the iso domain is attached to the cluster and everything is green. When attempting to attach the iso to the vm, I can see the pre and post output of the "/ovirt-engine/api/vms/<uuid>/cdroms" request, it shows the file id changing according to what the iso domain has available. However, whenever i attempt to power on the vm, from either the api or through the web interface, I get "Invalid ISO image path". Editing the vm through the web interface reveals that the "Attach CD" dropdown has selected the first iso ("A-Iso-Installer.iso", and I am trying to use the second). I ran a list against the cdrom service, found no issues with the xml that was returned. I confirmed that listing out available isos on the iso domain results in the expected id that I matched in the cdrom service of the vm from the api. If I ch oose the correct iso from the gui and save, the output looks the same as the api listing. Before and After gist: https://gist.github.com/robotman321/909255cbdc36fa62b730a953807f7397 The code im using to set the cdrom is the following: https://gist.github.com/robotman321/35617c96b96b329d5d1476e015aa9898 I did note that when i would run the update api code, it does change SOMETHING as when i go into the web interface the "Attach CD" value has gone back to the top value in the dropdown (the wrong iso). Has anyone seen this before, please tell me it's right in front of me, any help is appreciated. Thank you, Brad

OVN Configuration
by Armond Kuehn 22 Oct '18

22 Oct '18

High I've been trying for a couple months to setup an Ovirt Cluster with OVN/OVS implemented. I can make a network work on my home single server deployment but any time I create a vm on my hyperconverged setup the VM crashes stating it can't connect to the br:ex. (error messages aren't included because lab has 0 external connectivity). I assume this is due to nothing creating the OVN/OVS connections on each host in the manner that my single server does. I know there are ways to manage this such as ManageIQ but I haven't had any luck finding a good guide or walkthrough to get my systems to integrate those products. Does anyone know of where I could find one? Or willing to walk a dummy through it? Armond
