Issue with ovirt 4.4 after doing some incremental backups.

Hello, After doing a few vm backups, something breaks and I am unable to perform any operations. I cannot do incremental backups and even full backups doesn't work. I have this issue third time.

Hi oVirt land Hope you are well. Don't even know what to call this. But let me describe what I want to achieve. We have a cluster with say 100 vm's. But we want two use two hosts in the cluster two run only certain VM's. I think you can do that with affinity rules. But how can I restrict those two hosts to only run the VM's, meaning that no other VM's will run on them. I don't want to go and edit the 100 other VM's to not run on 2 hosts. Is there an easy way for doing this? Oracle VM uses pools, I dont know what vmware uses. Any advice will help. Regards Nar

Management Engine IP change
by Anton Louw 28 Jul '20

28 Jul '20

Hi All, Does somebody perhaps know the process of changing the Hosted Engine IP address? I see that it is possible, I am just not sure if it is a straight forward process using 'nmtui' or editing the network config file. I have also ensured that everything was configured using the FQDN. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

CentOS 8.2, ovVirt 4.4.1.8, SHE -- kernel: device-mapper: core: ovirt-ha-broker: sending ioctl 5401 to DM device without required privilege
by Dmitry Kharlamov 28 Jul '20

28 Jul '20

Good day! CentOS 8.2.2004 (Core), ovVirt 4.4.1.8-1.el8, storage type FC with multipathing. Please tell me what could be the problem. Messages are constantly poured into the console and / var / log / messages: kernel: device-mapper: core: ovirt-ha-broker: sending ioctl 5401 to DM device without required privilege Messages appeared during the installation process (SHE via CLI), during the LUN partitioning phase, and after that they do not stop. At the same time, the installation was successful and now everything is working fine. A similar problem is described here, but no solution has been proposed: https://bugzilla.redhat.com/show_bug.cgi?id=1838453 Best regards, Dmitry

Re: Failed to execute stage 'Environment customization': IPAddress() does not support netmasks or subnet prefixes! See documentation for details.
by James Loker-Steele 28 Jul '20

28 Jul '20

Hi Anton, I tried without the /24 it threw an error saying it wasn’t a correct cidr address 10.93.130.50/64 (it added the /64) Interesting though, I have manually created the ovirtmgmt bridge interface and assigned an IP address to it (as per another post) and it has gone past this step now without the /24. The part I am crashing out on is being unable to resolve the address. I can post the error shortly. This is strange behaviour as the host can resolve, but I will be adding dns addresses to the ovirtmgmt interface and trying again(post didn’t show to add them) When I installed <4.2 I didn’t get these issues it went smoothly. The problems seem related to ansible.

Adding hypervisor fails, yum links deprecated (Centos 7.7/ oVirt 4.3)
by wjb2130＠cumc.columbia.edu 28 Jul '20

28 Jul '20

Greetings. In a multi-hypervisor environment, we are running Centos 7.7.1908, with ovirt-4.3. There are problems adding a new hypervisor, because all the yum resources have switched in favor of newer versions. Is there a proceedure to add a hypervisor under the oVirt Virtualization manager while retaining an older, known working OS version like Centos 7.7.1908 ? Upgrading everything across the board isn't an immediate option. There are many VMs and hypervisors in production, and can't be disturbed. In sum: is it still possible to install known working 4.30.33-1.el7? All that is presented now is 4.30.46-1.el7 I ran: yum install vdsm-4.30.33-1.el7.x86_64. This completed. However, when I tried to add the resulting hypservisor using the oVirt web UI, that fails. Logs on that management server showed that the install process insists on using 4.30.46-1.el7. Any way to avoid this? 2020-07-22 20:30:58,621-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (VdsDeploy) [45782a5f] EVENT_ID: VDS_INSTALL_IN_PROGRESS_ERROR(511), An error has occurred during installation of Host hypervisor7: Failed to execute stage 'Package installation': [u'vdsm-4.30.46-1.el7.x86_64 requires lvm2 >= 7:2.02.186-7.el7_8.1'].

change lun for hosted_engine use?
by Philip Brown 27 Jul '20

27 Jul '20

I currently have a self-hosted engine, running in a dedicated ISCSI storage domain. I'd like to change the backend hardware for the storage. i think there's some longwinded and complicated method of shutting down the engine, backup, creating a NEW one, restore, and whoknowswhat. I was wondering though, if maybe there's a way to just add an iscsi lun to the storage domain, and tell ovirt, "Hey, move the stuff over to that other lun" ? Ive added the new lun already :) havent found a reference to move the files' residence though. If it helps, my end goal is to remove that lun completely. -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com
