Blog Post - Using Ceph Only Storage For oVirt Datacenter by Sandro Bonazzola – Wednesday 14 July 2021
by Matthew J Black 10 Nov '22

10 Nov '22

Hi All, In the above mentioned blog post (https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacente…) in mentions the line: "Follow oVirt documentation for setting up Cinderlib" with a link to this URL: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_us… This link is broken/obsolete/no longer available, so my question(s) is/are: Where can I obtain this information? Is there a new URL? Are these instructions no-longer required with the new oVirt v4.5.X? Can someone who has these instructions post/email them, please? Thanks in advance Dulux-Oz

[4.4.7] The latest guest agent needs to be installed and running on the guest
by Christoph Timm 28 Oct '22

28 Oct '22

Hi list, I have upgraded my oVirt from 4.4.4 to 4.4.7 and notice that some VMs have issues to report the performance information via the guest agent. I see the following message on the VMs: The latest guest agent needs to be installed and running on the guest The qemu-guest agent is installed on VMs (the VM OS is CentOS 8). Any advice how to troubleshoot this? I can see the stats will be presented in the GUI, if I migrate the VM to a different host. Best regards Christoph

Snapshot not working
by Facundo Badaracco 06 Oct '22

06 Oct '22

hi everyone, I have a glusterFS replica x3 node. I can't create snapshot. when I create it, if I select to save the memory, then in the disks section only appears the snapshot of the memory and in locked state. If instead, I remove the option to make snapshot of the memory, it does not make the snapshot saying "failed". Any idea?

oVirt 4.5.2 /var growing rapidly due to ovirt_engine_history db
by sohail_akhter3＠hotmail.com 05 Oct '22

05 Oct '22

Hi, We have recently upgrade our oVirt environment to 4.5.2 version. Environment is based on hosted-engine. Since we have upgrade we noticed rapid incrase in /var partition in engine VM. It is increasing very rapidly. If we vacuum ovirt_engine_history db, /var size reduces but next day size will increase again upto 5-10%. We did db vacuuming couple of time but not sure we it is increasing so rapidly. Here is the partial output of vacuuming that was done on 26-08-22. Table "host_interface_hourly_history" had more entries to be removed. Rest of the table had not much entries. Previously table "host_interface_samples_history" had entries to be removed. Any Idea what can be the reason for that? # dwh-vacuum -f -v SELECT pg_catalog.set_config('search_path', '', false); vacuumdb: vacuuming database "ovirt_engine_history" RESET search_path; SELECT c.relname, ns.nspname FROM pg_catalog.pg_class c JOIN pg_catalog.pg_namespace ns ON c.relnamespace OPERATOR(pg_catalog.=) ns.oid LEFT JOIN pg_catalog.pg_class t ON c.reltoastrelid OPERATOR(pg_catalog.=) t.oid WHERE c.relkind OPERATOR(pg_catalog.=) ANY (array['r', 'm']) ORDER BY c.relpages DESC; SELECT pg_catalog.set_config('search_path', '', false); VACUUM (FULL, VERBOSE) public.host_interface_samples_history; INFO: vacuuming "public.host_interface_samples_history" INFO: "host_interface_samples_history": found 3135 removable, 84609901 nonremovable row versions in 1564960 pages DETAIL: 0 dead row versions cannot be removed yet.

ovirt-engine-appliance Location (Pre-Installation)
by Matthew J Black 03 Oct '22

03 Oct '22

Hi All, A couple of Qs: During the `TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package]` stage of the Management Engine deployment, is this trying to install the ovirt-engine-appliance, or something else? When we do a pre-install of the ovirt-engine-appliance (ie dnf install ovirt-engine-appliance) where is this installed too, so that we can enter this information into the deployment script at the `Engine Appliance Image Path` stage? Cheers Dulux-Oz
