Error with LDAP
by Lucas Lamy 18 Feb '20

18 Feb '20

Hello everyone. I have previously configured LDAP connexion though ovirt-engine-extension-aaa-ldap-setup. The only working configuration was IBM Security Directory Server (the IBM Security Directory Server RFC-2307 Schema doesn't work), ladps and anonymous search user. But the LDAP server I’m testing is OpenLDAP and not IBM. Indeed with IBM the search and login are working fine when I test them with ovirt-engine-extensions-tool aaa. But when I try to add a LDAP User in the User Administration Panel I get this Error message : "Error while executing action AddUser : Internal Engine Error". None of the solutions I've found on previous threads seems to works. Does someone have an idea please ? Please find the logs attached. Thank you beforehand. Caused by: org.postgresql.util.PSQLException: ERROR: null value in column "external_id" violates not-null constraint Detail: Failing row contains (**user info**).

I wrote an article on using Ansible to backup oVirt VMs
by Jayme 18 Feb '20

18 Feb '20

I've been part of this mailing list for a while now and have received a lot of great advice and help on various subjects. I read the list daily and one thing I've noticed is that many users are curious about backup options for oVirt (myself included). I wanted to share with the community a solution I've come up with to easily backup multiple running oVirt VMs to OVA format using some basic Ansible playbooks. I've put together a blog post detailing the process which also includes links to a Github repo containing the playbooks here: https://blog.silverorange.com/backing-up-ovirt-vms-with-ansible-4c2fca8b3b43 Any feedback, suggestions or questions are welcome. I hope this information is helpful. Thanks! - Jayme

OK, that worked perfectly, thanks! I was able to run the restore and then run engine-setup.

Vm suddenly paused with error "vm has paused due to unknown storage error"
by Jasper Siero 18 Feb '20

18 Feb '20

Hi all, Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month. The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems. The vm runs without problems after unpausing it. Versions: CentOS Linux release 7.1.1503 vdsm-4.14.17-0 libvirt-daemon-1.2.8-16 vdsm.log: VM Channels Listener::DEBUG::2015-10-25 07:43:54,382::vmChannels::95::vds::(_handle_timeouts) Timeout on fileno 78. libvirtEventLoop::INFO::2015-10-25 07:43:56,177::vm::4602::vm.Vm::(_onIOError) vmId=`77f07ae0-cc3e-4ae2-90ec-7fba7b11deeb`::abnormal vm stop device virtio-disk0 error eother libvirtEventLoop::DEBUG::2015-10-25 07:43:56,178::vm::5204::vm.Vm::(_onLibvirtLifecycleEvent) vmId=`77f07ae0-cc3e-4ae2-90ec-7fba7b11deeb`::event Suspended detail 2 opaque None libvirtEventLoop::INFO::2015-10-25 07:43:56,178::vm::4602::vm.Vm::(_onIOError) vmId=`77f07ae0-cc3e-4ae2-90ec-7fba7b11deeb`::abnormal vm stop device virtio-disk0 error eother ........... libvirtEventLoop::INFO::2015-10-25 07:43:56,180::vm::4602::vm.Vm::(_onIOError) vmId=`77f07ae0-cc3e-4ae2-90ec-7fba7b11deeb`::abnormal vm stop device virtio-disk0 error eother specific error part in libvirt vm log: block I/O error in device 'drive-virtio-disk0': Unknown error 32758 (32758) ........... block I/O error in device 'drive-virtio-disk0': Unknown error 32758 (32758) engine.log: 2015-10-25 07:44:48,945 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-40) [a43dcc8] VM diataal-prod-cas1 77f07ae0-cc3e-4ae2-90ec-7fba7b11deeb moved from Up --> Paused 2015-10-25 07:44:49,003 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-40) [a43dcc8] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VM diataal-prod-cas1 has paused due to unknown storage error.

foreman integration
by eevans＠digitaldatatechs.com 18 Feb '20

18 Feb '20

I have ovirt 4.3 and foreman 1.9.3. both with self signed certificates. Foreman is a vm on the ovirt cluster. I added foreman as an external provider in ovirt, but when I try to add ovirt as a compute resource in foreman I get an ssl error. I found several fixes that prevented the error but the data center and quota fields would not populate. The exact error is: Unable to save SSL_connect returned=1 errno=0 state=error: certificate verify failed Has anyone else had this problem? Any help would be greatly appreciated.

Re: Move Self Hosted Engine to Standalone

I did get a little further. First I ran engine-cleanup on my new engine where I will be running the restore operation. (I had previously run the engine-setup script on this machine) Then I ran this- [root@engine ~]# engine-backup --mode=restore --file=ovirt-engine-backup-20200217125040.backup --log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db --restore-permissions Start of engine-backup with mode 'restore' scope: all archive file: ovirt-engine-backup-20200217125040.backup log file: ovirt-engine-backup-20200217125040.log Preparing to restore: - Unpacking file 'ovirt-engine-backup-20200217125040.backup' Restoring: - Files Provisioning PostgreSQL users/databases: - user 'engine', database 'engine' FATAL: Existing database 'engine' or user 'engine' found and temporary ones created - Please clean up everything and try again Time to research further for that FATAL error message. Isn't that the purpose of engine-cleanup though? Why the conflict? ________________________________ From: Robert Webb <rwebb(a)ropeguru.com> Sent: Monday, February 17, 2020 1:42 PM To: Jeremy Tourville <jeremy_tourville(a)hotmail.com>; users(a)ovirt.org <users(a)ovirt.org> Subject: Re: [ovirt-users] Move Self Hosted Engine to Standalone Try looking at the RHEV info here and go to section 6.2.2 and see if that helps. https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.0/ht… ________________________________________ From: Jeremy Tourville <jeremy_tourville(a)hotmail.com> Sent: Monday, February 17, 2020 2:26 PM To: Robert Webb; users(a)ovirt.org Subject: Re: [ovirt-users] Move Self Hosted Engine to Standalone OK, I was able to get the backup completed. I am a little confused on how to do the restore though. https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restori… Is this link even applicable? My environment is a single node, not EL based. Anyhow, here is what I have so far- [root@engine glusterfs]# engine-backup Start of engine-backup with mode 'backup' scope: all archive file: /var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup log file: /var/log/ovirt-engine-backup/ovirt-engine-backup-20200217125040.log Backing up: Notifying engine - Files - Engine database 'engine' - DWH database 'ovirt_engine_history' Packing into file '/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup' Notifying engine Done. [root@engine glusterfs]# I moved the backup file to my new engine. How do I perform the restore? The directions say: # engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --provision-dwh-db --restore-permissions What is the file name and log_file name?

What is this error message from?

I have seen this error message repeatedly when reviewing events. VDSM vmh.cyber-range.lan command HSMGetAllTasksStatusesVDS failed: low level Image copy failed: ("Command ['/usr/bin/qemu-img', 'convert', '-p', '-t', 'none', '-T', 'none', '-f', 'raw', u'/rhev/data-center/mnt/glusterSD/storage.cyber-range.lan:_vmstore/dd69364b-2c02-4165-bc4b-2f2a3b7fc10d/images/c651575f-75a0-492e-959e-8cfee6b6a7b5/9b5601fe-9627-4a8a-8a98-4959f68fb137', '-O', 'qcow2', '-o', 'compat=1.1', u'/rhev/data-center/mnt/glusterSD/storage.cyber-range.lan:_vmstore/dd69364b-2c02-4165-bc4b-2f2a3b7fc10d/images/6a2ce11a-deec-41e0-a726-9de6ba6d4ddd/6d738c08-0f8c-4a10-95cd-eeaa2d638db5'] failed with rc=1 out='' err=bytearray(b'qemu-img: error while reading sector 24117243: No such file or directory\\n')",) Can someone explain what this is? How do I get this cleared up/resolved?
