Convert raw images to qcow format
by Jonas
Hi there
I want to create incremental backups of a few imported VMs, but the VM disks are in the raw disk format which does not support incremental backup. Is there a way to convert existing disks from raw to qcow in oVirt? Since qemu-img can do this,I assume there must be a way..
Thank you

Pre-Installing OpenVSwitch For oVirt Self-Hoster Install - Issues?
by Matthew J Black
Hi All,
Is anyone aware of any issues (ie "gotchas") with pre-installing OpenVSwitch in preparation for an oVirt Self-Hosted install?
We're trying to work around an error we're getting with `hosted-engine --deploy` which spits out: `error: Failed to start network default\nerror: internal error: Network is already in use by interface bond1.a`. What we're thinking is if we pre-create the OVS Network (ie ovirtmgmt) then `hosted-engine --deploy` won't baulk and fail to install.
We've been grinding away at this and other issues for several weeks now and we're getting pretty desperate at this stage, to the point that we're starting to seriously consider giving up on oVirt completely - which would be a shame because it seems to be made for the job we want to do, but if we can't get it installed, let along working, then what's the point? (Plus I hate the thought of all the wasted time and effort - but that may just be the "suck cost fallacy" at work).
Anyway, if anyone has any insights we'd appreciate them.
Cheers

Re: OVS Task Error when Add EL Host
by Łukasz Pelczyk
I just hit the same error. Initially I got it on the beginning of installation (both netaddr and jmespath were not found). Seems that python3.9 is used so initially I solved it via pip3.9 install. Alternatively you can get the rpm packages from epel.
The same issues is on ovirt VM side. As a workaround I started deployment with pause (hosted-engine --deploy --ansible-extra-vars=he_pause_host=true). With that you can ssh to the instance, and manually run pip install which got me: 'Successfully installed jmespath-1.0.1 netaddr-0.8.0'.
This is just a workaround and proper fix should be reflected in engine VM image, or on the repos side.

Re: OVS Task Error when Add EL Host

Hi,
please try to downgrade ansible-core-2.13 to 2.12, oVirt doesn't support
2.13 on EL8 yet.

Martin

Question: How does ovirt storage domain differ from VMFS?
by jstk888＠gmail.com
Hello,
I was asked the other day what file system oVirt uses to store virtual machine images and how it differed from VMware VMFS. I had to admit that I didn't quite understand this aspect of oVirt. I've had a look around but haven't found an answer. I was wondering if someone could explain at a high level, how the underlying oVirt VM storage domain differs from VMFS? What file system is used? Does it use a file system at all?
Thank you.

OVS Task Error when Add EL Host

Hi,
Getting strange error when adding EL Host (Using CentOS Stream 8) :

Already checking the python-netaddr and its already installed on the system (both python3-netaddr and python38-netaddr).
Using oVirt 4.5. Anybody getting this same issue ?
Thanks before.

Snapshot not working
by Facundo Badaracco
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?

Issues with snapshot and template
by David Johnson
Good morning all,
Thank you in advance.
My current environment is ovirt 4.5.2.4-1.el8, running on centos 7.9.
I'm looking for advice on resolving two issues that have just come to light:
*Issue #1*: When I attempt to create a template from the oVirt GUI, I click
the "Make Template" button, enter the name for the new template, then click
the "OK" button. The OK button highlights, but nothing happens.
*There are no entries showing activity in the engine.log.*
*Issue #2:* When I delete a snapshot, after the snapshot is deleted, I
receive this error message from the GUI:
[image: image.png]
*ui.log entry:*

Yes. It is what I configured during the setup, and which I use when I ssh from the host to the engine VM.
Sorry, I should have mentioned this in my previous message.

oVirt 4.5.2 /var growing rapidly due to ovirt_engine_history db
by sohail_akhter3＠hotmail.com
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;
