Can other VMs migrate (who use the same storage server, so you know
it's not a storage/network issue)?

Please check/share /var/log/ovirt-hosted-engine-ha/* on all hosts, as
well as output of 'hosted-engine --vm-status' on all of them.

Good luck and best regards,

[ovirt-users] Hosted Engine can't migrate

[McNamara, Bradley]

I'm new to oVirt, but not new to virtualization technologies.  I've run into a 
wall, but the solution has gotta be simple.  I've seen other threads with the 
same issue, but a solution is never posted.

I've followed the guide perfectly.  I get  the self-hosted engine up and 
running with no issues.  I add hosts to the cluster, but it won't let me 
migrate the HE because of Hosted Engine HA score of "N/A" on every host except 
the one it was initially deployed on.  The physical servers are exactly the 
same:  same networks, storage, OS, patches, etc.  The additional hosts are 
added thru the HE GUI and are added without issue.  Is there a secret button I 
gotta push?

What am I missing?  This is with 4.3 on CentOS 7.9.

HELP!  Thanks.  :-)

Is there someone who has done an NON PERSISTANT VDI over oVirt using
kubevirt (on OKD) as the infraestructure for vm's?

We plan to do a 1.000.000 concurrent users deployment...

Any help is welcome!

[ovirt-users] Found a host rebooting - ways to watch?

[Chris Adams]

I just noticed that one of my oVirt physical hosts has been rebooting
due to an apparent hardware voltage fault.  It's a Dell, and I've got
their tools installed and am monitoring status, but the issue clears
itself.  It has apparently been doing this for a bit now, and we didn't
catch it because (a) there weren't any VMs on it (probably were the
first time but they were restarted elsewhere fast enough that it wasn't
noticed) and (b) it reboots fast enough that at most it pops up in our
monitoring system for one pass and then clears so our NOC either didn't
see it or assumed it was okay since it cleared.

oVirt has been logging alerts when it happens, but seeing that requires
someone to log in and check the logs (and we've got a bunch of different
systems to manage, including multiple oVirt clusters, so nobody is doing
that on a regular basis).  We monitor most things with SNMP and/or CLI
checks (we have PRTG, Nagios, and LibreNMS for various different
things).

What are people doing to monitor the health of their oVirt systems?  Is
it possible to get alerts emailed to admins?  Is there any SNMP support
in oVirt to allow external systems to monitor its health?  This setup is
on 4.3.10 if that matters.

In another recent thread already replied that you need to be at latest 4.3
that for oVirt is 4.3.10.
So, in particular, the backup has to be taken while in 4.3.10.

I would add the new server as an additional host, first preparing the
gluster volumes under the hood. In this way you achieve HA for engine and
guest VMs. When third server arrives, repeat and have a proper 3 node
replica self hosted engine setup.

Hi Sandro,

Thanks for the response. I logged onto oVirt this morning, and I see the node 
is in a “Unassigned” state. I can ping it, but cannot SSH, so there is 
something that is causing the host to be unresponsive.

On Saturday after I sent the mail, I opened a console to the node, and I saw 
the below entries before logging in:

audit:backlog limit exceeded

I the tried the solution of increasing the buffer size in the audit.rules file 
in /etc/audit/rules.d/ , as per below, but it did not resolve the issue.

## First rule - delete all
-D

## Increase the buffers to survive stress events.
## Make this bigger for busy systems
-b 8192

## Set failure mode to syslog
-f 1

Is it possible to upgrade the node to 4.4 while the engine is still on 4.3?

Thanks

Hi Everybody,

I have built a new host which has been running fine for the last couple of 
days. I noticed today that the host crashed, but it is not giving me a reason

It happened at 13:45 today, but I have given time before that on the logs as

Is there something I am missing here?

Not related to the crash, but I see in the logs that 5 out of 20 guests have

Also you seem to have some issues with some firewalld rules. (Maybe +Dominik

I don't see anything explaining why the host got rebooted.

Hello there,

I am trying to connect via ovirt-shell to my ovirt manager.

To do this I've downloaded the CA File

 to /tmp and set up my config in .ovirtshellrc :

autoconnect = True

extended_prompt = False
url = https://127.0.0.1/api

filter = False
session_timeout = None
ca_file = /tmp/pki-resource?resource=ca-certificate
dont_validate_cert_chain = True
key_file = None
password = somepassword
cert_file = None

So when I am trying to connect I get the following error:

(60, "Peer's certificate issuer has been marked as not trusted by the user.")

While researching I also found a pretty similar issue here 
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IYG6AQPII25366IZQ7E3VD622CKP2OSC/
 but unfortunally there is no solution posted.

Does anyone have a hint for me what could cause this problem or where to look 
else ?

Thanks a lot !

Hi Toni,

Hi,

Chances are, that this performance issue may be unrelated to oVirt.

The first thing that comes to my mind is that the system may have a 
bottleneck on the I/O.



Please have a look at:

iostat -x 5

The system may have problems with disk performance, if %util > 95 and 
avgqu-sz > 3 over longer periods of time.





Actually %util never goes beyond the 85%, being the average on 70%; for 
the avgqu-sz, the average value is about 25 (with peaks of 160 as far as 
I could see).


If that's not the case, you may next want to have a look at limits 
(/etc/security/limits.conf).


There may also be default limits which may be too low. (nofile, nproc 
come to my mind)




This file seems not to have been touched (all the content is commented out).


Are there any errors or warnings in the messages or audit logs?




Nothing special, I've checked for the last couple days and everything 
seems ok.



And also htop, iotop, vmstat may help to get a quick overview.




Yep, I've used most of these commands to check, but I've been unable to 
see something clarifying.


In my opinion the slowness could be caused for not using SSD disks and 
because of a low polling interval by the DWHd, but that's just my 
assumption and I've been unable to get some data that would confirm this.


Thanks for the help!

Nico


Hope this helps,

Hi,

We're running oVirt 4.3.8 and even if this is a problem we've had 
since a lot of time (I would say since 4.0.x), I decided to look for 
help in case anything can be done.


Our environment is heavily used by users in our University (about 
3000 users), and currently our oVirt infrastructure has 1928 virtual 
machines, being 882 of them currently running. We have a separate 
physical machine for the manager node, and the problem is that this 
machine is very, very, very slow, despite it has (from my point of 
view) enough physical resources to run efficiently.


By slow I mean even the SSH access to it takes about 10 seconds, not 
just the admin/user portals. Any operation takes enough time to make 
the experience not comfortable to our users (enter the VM portal, 
start a VM, open a console...).


Node machine's parameters are:
18GB of RAM memory
1 processor with 12CPUs

After a quick glance, we need some more information. 
I think it is better to open a ticket and provide the below information to 
verify the gluster issue 

1. gluser volume info 
2. gluster logs when you observe this issue. 
3. Explain the scenario in the ticket when this happened.

[ovirt-users] Re: VM with illegal snapshots

[Florian Schmid via Users]

Hi, 




I have also sometimes the issue with snapshots or disk move, which is also 
related to snapshots, when the engine process is running for a longer time. 

After restarting the engine service, then it is working again for several 
weeks, until it gets too long and issues starting again to happen. 




I had never the time to dig in deeper here and I'm never on a version, which is 
still supported, but it would be nice to here, if you maybe have the same 
issue? 

How long was your engine process running, until the issues have started?

Betreff: [ovirt-users] Re: VM with illegal snapshots 

Hello 

We have the same issue, and not just one VM, we have about 10-15 VMs that have 
either snapshots that are illegal or snapshots that is not possible to remove. 
This have been an issue for quite some time, all since beginning of 4.3 we get 
"vm with illegal snapshots" almost every week, and most often we can remove the 
snapshot and all is ok, but now this have escalated quite much and leaves us 
with customer VM that we may not be able to reboot or that the disk gets 
corrupted, that have happed a few times. 
This is the VM with most snapshots that we are unable to remove any of them. 

Engine is on 4.3.10 and hosts on 4.3.9 

How can i safely remove these snapshots? 
(I am not super comfortable around database "hacking" so some informative 
description would be much appreciated.) 

And how can we eliminate that these things happen? 

Cheers 
Magnus

Hi, 
due to a bug in our Ovirt integrated backup system now we have some VMs 
with snapshots in illegal state. 

It seems that there's an inconsistency between the db and the real 
status of images on disk. 

Let me show an example: 

engine=# select 
image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active

so image guid a4c86a68-9123-454c-b417-1b15038a4bf2 is not present on 
disk, i think that the image was correctly merged but not removed from 
the database. 

Any suggestion on how to fix the database to reflect the real situation 
on disk?? 



In those cases I delete the entry from engine DB to reflect the status of the 
image chain.

Assunto: Re: [ovirt-users] Cannot copy or move disks 

After a quick glance, we need some more information. 
I think it is better to open a ticket and provide the below information to 
verify the gluster issue 

1. gluser volume info 
2. gluster logs when you observe this issue. 
3. Explain the scenario in the ticket when this happened. 

Regards

I'm pretty sure this is a bug on gluster side.

[ovirt-users] Re: VM with illegal snapshots

[Magnus Isaksson]

Hello

We have the same issue, and not just one VM, we have about 10-15 VMs that have 
either snapshots that are illegal or snapshots that is not possible to remove.
This have been an issue for quite some time, all since beginning of 4.3 we get 
"vm with illegal snapshots" almost every week, and most often we can remove the 
snapshot and all is ok, but now this have escalated quite much and leaves us 
with customer VM that we may not be able to reboot or that the disk gets 
corrupted, that have happed a few times.
[cid:2c902230-ccb6-4e63-98f6-ea667ba239bf]
This is the VM with most snapshots that we are unable to remove any of them.

Engine is on 4.3.10 and hosts on 4.3.9

How can i safely remove these snapshots?
(I am not super comfortable around database "hacking" so some informative 
description would be much appreciated.)

And how can we eliminate that these things happen?

Cheers
 Magnus

so image guid a4c86a68-9123-454c-b417-1b15038a4bf2 is not present on
disk, i think that the image was correctly merged but not removed from
the database.

Any suggestion on how to fix the database to reflect the real situation
on disk??
In those cases I delete the entry from engine DB to reflect the status of the 
image chain.

TIA

[ovirt-users] How to create a backup in event of hardware failure of a single hosted engine?

[ernestclydeachua]

Hello everyone,
Currently we have a single bare metal that hosts oVirt and glusterFS which 
later on to be converted to a 3 nodes for HCI, currently another bare metal is 
coming this week and was planning to  initially create it as a backup.

is it possible to deploy a new hosted engine then create a gluster volume for 
1st one as a backup domain then attach it to the new one if hardware failure 
occurred, or there is another kind of setup that can be done?

You are right. This was added for:

https://bugzilla.redhat.com/show_bug.cgi?id=1387146

The request there wasn't for full proxy support, just a warning.

This just logs all env vars when running ansible.

Similarly. Was added for:

https://bugzilla.redhat.com/1588720

And to further clarify. Adding full proxy support requires:

1. Some design and development work
2. Routinely testing deployment with a proxy
3. Fix new bugs as they are found

It's not clear this is worth it.

That said, patches are welcome :-). To consider including it, it
should obviously be written so that it also seamlessly works without a
proxy.
