[CFP] Virtualization & IaaS Devroom
by Piotr Kliczewski 11 Dec '20

11 Dec '20

We are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2021, to be hosted virtually on February 6th 2021. This year will mark FOSDEM’s 21th anniversary as one of the longest-running free and open source software developer events, attracting thousands of developers and users from all over the world. Due to Covid-19, FOSDEM will be held virtually this year on February 6th & 7th, 2021. About the Devroom The Virtualization & IaaS devroom will feature session topics such as open source hypervisors and virtual machine managers such as Xen Project, KVM, bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as KubeVirt, Apache CloudStack, Foreman, OpenStack, oVirt, QEMU and OpenNebula. This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at users or developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM.

Nodes in CentOS 8.3 and oVirt 4.4.3.12-1.el8 but not able to update cluster version
by Gianluca Cecchi 11 Dec '20

Hello, my engine is 4.4.3.12-1.el8 and my 3 oVirt nodes (based on plain CentOS due to megaraid_sas kernel module needed) have been updated, bringing them to CentOS 8.3. But if I try to put cluster into 4.5 I get the error: " Error while executing action: Cannot change Cluster Compatibility Version to higher version when there are active Hosts with lower version. -Please move Host ov300, ov301, ov200 with lower version to maintenance first. " Do I have to wait until final 4.4.4 or what is the problem? Does 4.5 gives anything more apart the second number... (joking..)?

oVirt 4.4: Self-hosted engine deployment fails with backup restore from 4.3 engine
by Oliver Leinfelder 11 Dec '20

11 Dec '20

Hi there, I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to version 4.4 in a self-hosted engine environment. My idea was: Set up a new host with a clean ovirt node 4.4 installation, then deploy the hosted engine on this with a restored backup from the production cluster and go from there. This however fails with the following error: 2020-05-27 00:17:08,886+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 {'msg': 'non-zero return code', 'cmd': ['engine-setup', '--accept-defaults', '--config-append=/root/ovirt-engine-answers'], 'stdout': "[ INFO ] Stage: Initializing\n[ INFO ] Stage: Environment setup\n C onfiguration files: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf, /etc/ovirt-engine-setup.conf.d/10-packaging.conf, /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf, /root/ovirt-engine-answers\n Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20200527001657-fyeueu.log\n Version: otop i-1.9.1 (otopi-1.9.1-1.el8)\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - AppStream\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - Base\n[ INFO ] DNF Downloading 1 files, 0.00KB\n [...] ... anwsers from backup config follow ....

Another illegal disk snapshot problem!
by Joseph Goldman 10 Dec '20

10 Dec '20

Hi List, oVirt 4.3 I know there have been threads about this before - but I am unable to find the exact scenario I am facing. I have a VM with 3 snapshots - Active, and 2 dated ones (technically created by vProtect) After trying to do a fresh snapshot in the GUI it failed out and marked one of the old snapshot disks as 'illegal' - then the other tried to follow suit. I tried 'unlocking' the entity using the unlock_entity.sh tool but any action reverts them back to illegal. Following previous advice - I can see the VDSM status is all showing LEGAL: image: 23710238-07c2-46f3-96c0-9061fe1c3e0d - *c3dadf14-bb4e-45a7-8bee-b9a01fe29ae1* *status: OK, voltype: INTERNAL, format: RAW, legality: LEGAL, type: SPARSE, capacity: 107374182400, truesize: 18402942976** * - *a6d4533b-b0b0-475d-a436-26ce99a38d94** ** status: OK, voltype: INTERNAL, format: COW, legality: LEGAL, type: SPARSE, capacity: 107374182400, truesize: 21521768448* - 4b6f7ca1-b70d-4893-b473-d8d30138bb6b status: OK, voltype: LEAF, format: COW, legality: LEGAL, type: SPARSE, capacity: 107374182400, truesize: 12617457664 The 2 bold entries are the 'illegal' snapshots. Looking in the DB see's: select image_guid,parentid ,imagestatus ,vm_snapshot_id ,volume_type ,volume_format ,active from images where image_group_id='23710238-07c2-46f3-96c0-9061fe1c3e0d'; image_guid | parentid | imagestatus | vm_snapshot_id | volume_type | volume_format | active --------------------------------------+--------------------------------------+-------------+--------------------------------------+-------------+---------------+-------- 4b6f7ca1-b70d-4893-b473-d8d30138bb6b | a6d4533b-b0b0-475d-a436-26ce99a38d94 | 1 | d5044ae5-dc48-4700-9e46-d61e676c73fc | 2 | 4 | t c3dadf14-bb4e-45a7-8bee-b9a01fe29ae1 | 00000000-0000-0000-0000-000000000000 | 4 | 57337968-28da-4b03-ac40-134a347d8c11 | 2 | 5 | f a6d4533b-b0b0-475d-a436-26ce99a38d94 | c3dadf14-bb4e-45a7-8bee-b9a01fe29ae1 | 4 | d2d82724-9fe7-452c-a114-f8d70b555520 | 2 | 4 | f So from here previous advice has been to do things such as delete the snapshot/disk etc but thats when they showed as illegal status. I also notice the Active Image is not the same image that has a parentid of all 00000's so im not sure on the process of possibly deleting the other snapshots and disks cleanly and/or safely. Deleting or any tasks in the gui 100% fails and its at a point that if I shut down the (critical) VM it will not come back on because of these status'. On top of this what is a good way to take a clean, manual backup of current in use disk before I start playing with this in case worse comes to worse I have to try build it as a new server (As at this point I can't trust my vProtect backups) Any help appreciated. Thanks, Joe

ovirt 4.3 - locked image vm - unable to remove a failed deploy of a guest dom
by 3c.monitor＠gruppofilippetti.it 09 Dec '20

09 Dec '20

Hi all. I've deployed a VM from a corrupted template (it's disk is missing, but I've checked it later...). My Software Version is:4.3 Now, I have an unmanaged VM in inventory and unable to remove it too. It's reference is "locked image". I've restarted ovirt-engine many times on self-hosted engine and hosts too, but no benefits. So, what's now? I've also consulted: https://access.redhat.com/solutions/396753 but still no results. No tasks or items results to be "locked"... Any other ideas? Thanks a lot.

Re: difference between CPU server and client family
by Vinícius Ferrão 09 Dec '20

09 Dec '20

AFAIK Client is for the i3/i5/i7/i9 families and the other one is for Xeon platforms. But you have pretty unusually Xeon, so it may be missing some flags that will properly classify the CPU. You can run this on the host to check what’s detected: [root]# vdsm-client Host getCapabilities Sent from my iPhone On 8 Dec 2020, at 10:52, jb <jonbae77(a)gmail.com> wrote:

Hi, How easy would it be to re-use the existing Storage Domain used for 4.3 Self Hosted Engine VM when upgrading to oVirt 4.4?
