April 2022 - Users - Ovirt List Archives

by jorgevisentini＠gmail.com

Hello everyone! First, I would like to thank everyone involved in this wonderful project. I leave here my sincere thanks! Does anyone know if it is possible to list all snapshots automatically? It can be by ansible, python, shell... any way that helps to list them all without having to enter Domain by Domain. Thank you all!

Synology NAS

by Keith Forman

Hi all I just wanted to find out if anyone has had any success configuring 2x Synology NAS devices in a High Availability setup as the storage for their Ovirt environment? So that if the active NAS goes down, the passive NAS takes over? Regards --

ovirt hosted engine restore backup fails: remot host identifaction changed

by jeroen.gui＠telenet.be

I have a backup file from our ovirt hosted engine. When I try to run "hosted-engine --deploy --restore-from-file=backup.bck" on the same machine with a fresh install of ovirt node 4.3 I get this error after some minutes: [ ERROR ] fatal: [localhost -> ovirt.*mydomain.com*]: FAILED! => {"changed": false, "elapsed": 185, "msg": "timed out waiting for ping module test success: Failed to connect to the host via ssh: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\r\n@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @\r\n@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\r\nIT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!\r\nSomeone could be eavesdropping on you right now (man-in-the-middle attack)!\r\nIt is also possible that a host key has just been changed.\r\nThe fingerprint for the ECDSA key sent by the remote host is\nSHA256:aer7BMZyKHhfzMXX4pzVULHN7OwSSNDrCuOyvdmG8sQ.\r\nPlease contact your system administrator.\r\nAdd correct host key in /dev/null to get rid of this message.\r\nOffending ED25519 key in /var/lib/sss/pubconf/known_hosts:6\r\nPassword authentication is disabled to avoid man-in-the-middle attacks.\r\nKeyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.\r\nPermission denied (publickey,gssapi-keyex,gssapi-with-mic,password)."} I can't find anything in the docs about this problem. I already removed all the entries in /var/lib/sss/pubconf/known_hosts on my ovirt host machine. But that didn't change anything. Is their something wrong with the backup. At the moment I have 2 other hosts running my VM's but no ovirt manager.

Failed to start service jboss.deployment.subunit."engine.ear"."webadmin.war".STRUCTURE Ovirt 4.4.10 Self-hosted engine

by wthomas85＠gmail.com

I'm trying to deploy a new ovirt 4.4.10 self-hosted engine. Whenever I try to access the server via a web browser I get 404 - Not Found. In /var/log/ovirt-engine/server.log I see Failed to start service jboss.deployment.subunit."engine.ear"."webadmin.war".STRUCTURE due to a java.io.FileNotFoundException for /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/deployment38ca8fb55a7d2674/gwt-servlet.jar-ab669e949f887030/gwt-servlet.jar. Inside /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/deployment38ca8fb55a7d2674/, I do not have the gwt-servlet.jar-ab669e949f887030 dir. I can create it and copy gwt-servlet.jar to it and set the proper ownership and permissions, but then I am not sure how to restart jboss. I am not sure what is happening that would prevent the gwt-servlet.jar dir from being created inside the /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/ dir. I can see bll.jar, 4 branding.jar dirs, docs.jar, enginesso.jar, scheduler.jar, services.jar, vdsbroker.ja r, and welcome.jar dirs inside /var/lib/ovirt-engine/jboss_runtime/tmp/vfs/deployment/deployment38ca8fb55a7d2674 but no gwt-servlet.jar dir unless I make it myself.

Network filters in oVirt : zero-trust, IP and port filtering

by ravi k

Good people of the community, Hope you are all doing well. We are exploring the network filters in oVirt to check if we can implement a zero-trust model at the network level. The intention is to have a filter which takes two parameters, IP and PORT. After that there will be a 'deny all' rule. We realized that none of the default network filters offer such a functionality and the only option is to write a custom filter. Why don't we have such a filter in libvirt and thereby in oVirt? Someone would've already thought about such a use case. So I was thinking maybe network filters aren't meant to be used for implementing such functionalities like zero-trust? Also what are some practical use cases of the default filters that are provided? I was able to understand and use the clean-traffic and clean-traffic-gateway. Regards, ravi
