Failed to synchronize networks of Provider ovirt-provider-ovn
by Kapetanakis Giannis 14 Sep '18

14 Sep '18

Hi, After upgrading to 4.2.1 I have problems with ovn provider. I'm getting "Failed to synchronize networks of Provider ovirt-provider-ovn." I use custom SSL certificate in apache and I guess this is the reason. I've tried to update ovirt-provider-ovn.conf with [OVIRT] #ovirt-ca-file=/etc/pki/ovirt-engine/ca.pem ovirt-ca-file=/etc/pki/ovirt-engine/apache-ca.pem but still no go Any tips on this? thanks G

Unable to backend oVirt with Cinder

------=_Part_51316288_608143832.1472587678781 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit I've got Cinder configured and pointed at Ceph for it's back end storage. I can run ceph commands on the cinder machine and cinder is configured for noauth and I've also tried it with Keystone for auth. I can run various cinder commands and it'll return as expected. When I configure it in oVirt it'll add the external provider fine, but when I go to create a disk it doesn't populate the volume type field, it's just empty. The corresponding command for cinder: cinder type-list and cinder type-show <name> returns fine and it is public. Ovirt and Cinder are on the same host so it isn't a firewall issue.

Recovering oVirt-Engine with a backup before upgrading to 4.2

--_000_41e0a4df7d7b4b04824f154982fe953fepsaero_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi All, I'm still facing issues with my HE engine. Here are the steps that I took t= o end up in this situation: - Update Engine from 4.1.7 to 4.1.9 o That worked as expected - Automatic Backup of Engine DB in the night - Upgraded Engine from 4.1.9 to 4.2.1 o That worked fine - Noticed Issues with the HA support for HE o Cause was not having the latest ovirt-ha agent/broker version on hosts - After updating the first host with the latest packages for the Ag= ent/Broker engine was started twice o As a result the Engine VM Disk was corrupted and there is no Backup of = the Disk o There is also no Backup of the Engine DB with version 4.2 - VM disk was repaired with fsck.ext4, but DB is corrupt o Can't restore the Engine DB because the Backup DB from Engine V 4.1 - Rolled back all changes on Engine VM to 4.1.9 and imported Backup o Checked for HA VMs to set as disabled and started the Engine - Login is fine but the Engine is having trouble picking up and inf= ormation from the Hosts o No information on running VMs or hosts status - Final Situation o 2 Hosts have VMs still running and I can't stop those o I still have the image of my corrupted Engine VM (v4.2) Since there were no major changes after upgrading from 4.1 to 4.2, would it= be possible to manually restore the 4.1 DB to the 4.2 Engine VM to this up= and running again or are there modifications made to the DB on upgrading t= hat are relevant for this ? All my work on rolling back to 4.1.9 with the D= B restore failed as the Engine is not capable of picking up information fro= m the hosts. Lessons learned is to always make a copy/snapshot of the engin= e VM disk before upgrading anything. What are my options on getting back to= a working environment ? Any help or hint is greatly appreciated.

Mailing-Lists upgrade

It should not take a full hour to migrate as we already made incremental synchronization with the current system but better keep some margin. The system will then take over delivery of the mails but might be a bit slow at first as it needs to reindex all the archived mails (which might take a few hours). To manage your subscriptions and delivery settings you can do this easily on the much nicer web interface (https://lists.ovirt.org) There is a notion of account so you don't need to login separately for each ML.= You can Sign In using Fedora, GitHub or Google or create a local account if you prefer. Please keep in mind signing in with a different method would create separate accounts (which cannot be merged at the moment). But you can easily link your account to other authentication methods in your settings (click on you name in the up-right corner -> Account -> Account Connections). As for the original mail archives, because the previous system did not have stable URLs, we cannot create mappings to the new pages. We decided to keep the old archives around on the same URL (/pipermail), so the Internet links would still work fine. Hope you'd be happy with the new system. \_o< --AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv-- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEcpcqg+UmRT3yiF+BVen596wcRD8FAlmwx0MACgkQVen596wc RD9LTQ/+LtUncsq9K8D/LX8wqUTd6VyPwAD5UnAk5c3H/2tmyVA0u7FIfhEyPsXs Z//LE9FEneTDqDVRi1Dw9I54K0ZwxPBemi71dXfwgBI7Ay0ezkbLWrA168Mt9spE tHAODEuxPt2to2aqaS4ujogrkp/gvEP8ILoxPEqoTPCJ/eDTPAu/I1a2JzjMPK3n 2BBS6D8z0TLAf7w1n72TsgX2QzJW57ig/0HELyjvat2/K8V3HSrkwiKlsdULQDWe zB+aMde7r6UoyVKHqlu4asTl2tU/lGZ+e31Hd9Bnx1/oZOJdzslGOhEo9Qoz6763 AHWU9LKiK4NtxYHj2UQTWhndr8PiTtTmR73eIDmkb0cuRXxzjl9VQbwYJ0Kbrmfp attTqpc2CnEojTNXUUNSmNxotZoYXZiX8ZvjPfSgRVr15TUYujzlOfG+lUynbQMV 9rQ9/m58wgwYUymMpOIsRGaIcAKzjm+WpuuVnO+bS2AfmcBkGMQRoIhfV+3SkS8q kT9cDXgcDZOzVFcnZZB4EjbycMcPgZDcoHxU88VdYH+jFJYvvb21esgswVF/wJ2Z uEI/chp4+ADaQhl8ehZNWMSZq125v6SeirPhBNgLG7zFVZI1S9Tm/6qFmH+ajQY7 nCk1X9HZlB1ubex1X+HibRz9QKOilkMgkADyJ4yMDckwYj93sx0= =l6uN -----END PGP SIGNATURE----- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq--

vdsClient is removed and replaced by vdsm-client
by Irit Goihman 16 Apr '18

16 Apr '18

Hi All, vdsClient will be removed from master branch today. It is using XMLRPC protocol which has been deprecated and replaced by JSON-RPC. A new client for vdsm was introduced in 4.1: vdsm-client. This is a simple client that uses JSON-RPC protocol which was introduced in ovirt 3.5. The client is not aware of the available methods and parameters, and you should consult the schema [1] in order to construct the desired command. Future version should parse the schema and provide online help. If you're using vdsClient, we will be happy to assist you in migrating to the new vdsm client. *vdsm-client usage:* vdsm-client [-h] [-a ADDRESS] [-p PORT] [--unsecure] [--timeout TIMEOUT] [-f FILE] namespace method [name=value [name=value] ...] Invoking simple methods: # vdsm-client Host getVMList ['b3f6fa00-b315-4ad4-8108-f73da817b5c5'] For invoking methods with many or complex parameters, you can read the parameters from a JSON format file: # vdsm-client Lease info -f lease.json where lease.json file content is: { "lease": { "sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2", "lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5" } } It is also possible to read parameters from standard input, creating complex parameters interactively: # cat <<EOF | vdsm-client Lease info -f - { "lease": { "sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2", "lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5" } } EOF *Constructing a command from vdsm schema:* Let's take VM.getStats as an example. This is the entry in the schema: VM.getStats: added: '3.1' description: Get statistics about a running virtual machine. params: - description: The UUID of the VM name: vmID type: *UUID return: description: An array containing a single VmStats record type: - *VmStats namespace: VM method name: getStats params: vmID The vdsm-client command is: # vdsm-client VM getStats vmID=b3f6fa00-b315-4ad4-8108-f73da817b5c5 *Invoking getVdsCaps command:* # vdsm-client Host getCapabilities Please consult vdsm-client help and man page for further details and options.

ovirt snapshot issue
by Alex K 11 Apr '18

Hi folks, I am facing frequently the following issue: On some large VMs (Windows 2016 with two disk drives, 60GB and 500GB) when attempting to create a snapshot of the VM, the VM becomes unresponsive.

I can resume the VM only by powering off and on. I am using ovirt 4.1.9 with 3 nodes and self-hosted engine. I am running mostly Windows 10 and Windows 2016 server VMs. I have installed latest guest agents from: http://resources.ovirt.org/pub/ovirt-4.2/iso/oVirt-toolsSetup/4.2-1.el7.cen… At the screen where one takes a snapshot I get a warning saying "Could not detect guest agent on the VM. Note that without guest agent the data on the created snapshot may be inconsistent". See attached. I have verified that ovirt guest tools are installed and shown at installed apps at engine GUI. Also Ovirt Guest Agent (32 bit) and qemu-ga are listed as running at the windows tasks manager. Shouldn't ovirt guest agent be 64 bit on Windows 64 bit? Any advice will be much appreciated. Alex
