[ovirt-users] Re: 4.3.10 cannot start VMs because of an error with USB

[lizhij...@fujitsu.com]

I recalled that i got similar error if i changed the default usb controllers to 
the error ones by before vm start hook.
I think you can try to check the ovirt-engine log where it will throw more 
details

[ovirt-users] Re: gluster service on the cluster is unchecked on hci cluster

[Strahil Nikolov via Users]

Well... not yet.Check if the engine detects the volumes and verify again that 
all glustereventsd work.
I would even consider restarting the engine, just to be on the safe side.
What is your oVirt version ? Maybe an update could solve your problem.

well, on db side it looks like cluster has gluster_service disabled...

engine=# select virt_service, gluster_service from cluster;
  virt_service | gluster_service
--+-
  t            | f
(1 row)

still don't know why the checkbox is disabled. Would it be safe to 
enabled gluster_service directly in db? I suppose no... :-)

[ovirt-users] Re: Seeking best performance on oVirt cluster

[Strahil Nikolov via Users]

I would consider using smaller templates .Also, give it a try with iSCSI.

  On Wed, Jul 13, 2022 at 3:10, Pascal D wrote:   I 
have experienced the same performance problem in creating new template or 
creating new stateful image from template. I have traced it to the use of 
qemu-img convert which is very very slow. 

Currently a template creation on my setup, takes around 29m for a 45G image 
when a simple copy over NFS  takes 1m26s over a 10G network which is expected 
since there is roughly as many read as write over the network (4Gbps)

Adding --cache writeback to qemu-img improves from 29m to around 8m but 
according to a prior comment on this mailing list might not work on all 
platform.

Hope that helps

[ovirt-users] Re: Import KVM VMs on individual iSCSI luns

[spcts1 spcts1]

Thank you Nir - this was very helpful.
It would be so much easier configuring this in a greenfield environment.  Now 
I'm battling network/bridge issues.  Probably due to the fact that I 
pre-created the bonds and bridges on the Hosts.  It looks like I'll need to 
backtrack and do some of that work within oVirt.

You can check in the job table,

select *
from job
where correlation_id = 'd19c0b79-76dd-40df-af41-fc18e59bb536';


No job returned from job query.
Can I proceed to remove 2 rows from command_entities referencing
6ae544f6-b608-4d8d-9f99-eabd5d5db0ad?

[ovirt-users] Q: Instaling Ovirt Engine 4.4.10 on Clean CentOS 8 Stream

[Andrei Verovski]

Hi,

Since I run into a lot of problems upgrading 4.4.7 to 4.4.10, is it OK to 
install clean
CentOS-Stream-8-x86_64-20220712-dvd1.iso 

and restore from backup?
4.4.10 release long before Stream 20220712, may I run again into similar 
problems, or I need to use earlier snapshot of Stream 8 ?

I use dedicated engine PC, not hosted engine.

Thanks in advance for any suggestion(s)

Andrei

    it looks like root of the problem is that Gluster service is
    disabled in
    cluster settings and cannot be enabled. But it was enabled before...
    also I have to manually install vdsm-gluster when I (re)install new

    I have no access to other HCI installation so I cannot compare

Its very frustrating ...


Yes, it is. Certificate refreshing should be automagic job on background...

If I understand it right, your hosted engine is running?

hosted-engine --vm-status

on any hosts state that cluster is in global maintenance mode? You 
should see this line at the end of output


!! Cluster is in GLOBAL MAINTENANCE mode !!

[ovirt-users] Re: gluster service on the cluster is unchecked on hci cluster

You can use the workaround from the github issue and reatart the 
glustereventsd service.


ok, workaround applied, glustereventsd service enabled and started on 
all hosts.


I can see this log entry in volume Events

Detected change in status of brick 
10.0.4.11:/gluster_bricks/engine/engine of volume engine of cluster 
McHosting from UNKNOWN to UP via gluster event.


but Bricks tab shows still two (.12 and .13) of three bricks in Unknown 
state. From command line point of view all bricks are up and healthy.


it looks like engine thinks that gluster service is disabled in cluster 
but I cannot enable it because checkbox is disabled. In my other (FC 
based) oVirt instance Gluster Service checkbox is not selected but not 
disabled. So I am interested what could make that checkbox inactive...


For the vdsm, you can always run '/usr/libexec/vdsm/vdsmd_init_common.sh 
--pre-start' which is executed by the vdsmd.service before every start 
(ExecStartPre stanza) and see if it complains about something.


[root@ovirt-hci03 ~]# /usr/libexec/vdsm/vdsmd_init_common.sh --pre-start

it looks like root of the problem is that Gluster service is
disabled in
cluster settings and cannot be enabled. But it was enabled before...
also I have to manually install vdsm-gluster when I (re)install new
host, but bricks from this host are in unknown state in admin. Maybe
vdsm-gluster is not correctly configured? Maybe glustereventsd is not
running? I am just guessing...

I have no access to other HCI installation so I cannot compare
differences.

I would be really happy if someone could tell me what circumstances
could disable Gluster service checkbox in admin and how to enable it
again...

Jiri

[ovirt-users] Keycloak - the default OpenID/SSO provider for oVirt Engine

[Artur Socha]

Hi,
With Ovirt 4.5.1 release [1], the Keycloak based authentication is enabled
by default for fresh/new installations.
Here [2] you can find some usage scenarios describing when/how it is
enabled.

In short - if you just want to login to oVirt Admin / VM / Monitoring
portal, please use 'admin@ovirt' user and the password provided during
engine-setup.
There is ongoing work to make it more explicit [3] and it will be addressed
soon.

For  Rest API access, the full user with profile name is required as
username:  admin@ovirt@internalsso
Here is a sample 'curl' illustrating the flow:
$ curl -k -H "Accept: application/json" '
https://ENGINE_FQDN/ovirt-engine/sso/oauth/token?grant_type=password=admin@ovirt@internalsso=SECRET=ovirt-app-api
'
And the token response:
{"access_token":"eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICJEdS10MlVQd0JaZ0gtRU1JUkRTRHFxNFZIOUhZbnc4Nkk5QUlGOERxZ1l3In0.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.Ov2IJ-ghtXSB6eb7osWZgT_yeb4prBgVzUU9vAY_VMoDr-ie5bMYBUyinYvNHWpBbYaFGNjg6bC7PHz3-s5H1rxXN1wH13wtIlO4obUbPt8wEb58Slrr42kXBoLLLDrXE3Af9LlabtNjJ0z-a5reSUZmOdVYiJl9sEF4YwG9177mwUSJz7VLQAI1hKN1pg6Ox1sJj2fBwdBqjIiRXsw-KBwoMQx9JmuMk9wCr5-gI5f8I-9Vqizb8Lf5ZJ4SMf35Wy3R8dwQeXXau_7t5zDe9wO9wnc9RfOMCuDCc359-oLDFmtrahgrMjmDx5YrQHol6jC43S_7gQ_2IPLE_TlqiQ","scope":"ovirt-app-api

In order to change default Keycloak configuration or set up any additional
identity providers you need to access the Keycloak Administration Panel (

By default, on a fresh installation, you can login using 'admin' and the
password provided during engine-setup.

Keycloak allows to easily use all the features that were previously
supported by oVirt in-house authentication implementation plus many more
almost for free - multi factor authentication,  3rd party identity
providers (ie. github,

[ovirt-users] Re: Cannot deserialize - engine doesn't start

[Benny Zlotnik]

Which ovirt version is this? Can you attach the full log?
As well as the output of
$ psql -U engine -d engine -c "\x on" -c "select * from command_entities"

This can likely be resolved by removing the relevant row from
command_entities, but first let's get a better understanding of what's
going on

[ovirt-users] Cannot deserialize - engine doesn't start

[Giulio Casella]

Hi guys,
I'm in big troubles.

Since last night my ovirt engine is unavailable (won't correctly start).
Process ovirt-engine is running, and systemd doesn't complain (systemctl 
status is ok).

Digging in engine.log I can find an error:

2022-07-13 09:57:48,314+02 ERROR 
[org.ovirt.engine.core.utils.serialization.json.JsonObjectDeserializer]

  "commandId" : [ "org.ovirt.engine.core.compat.Guid", {

  } ],

2022-07-13 09:57:48,315+02 ERROR

on org.ovirt.engine.core.bll.tasks.CommandContextsCacheImpl@3f52ccce

[...cut...]

During the night there was a job that was moving a disk (2.5TB) from a 
storage domain to another. I think it's related.


Any ideas?


TIA,
