Yes, sadly Fedora is moving too fast to be able to match the changes
they've introduced between Fedora 24 and Fedora 27 which will be GA next
week.
I hope we'll be able to re-align with Fedora with oVirt 4.3.

Re: [ovirt-users] [ANN] oVirt 4.2.0 First Beta Release is now available for testing

[Arman Khalatyan]

I just tested the new 4.2, looks new shiny UI, thanks.

I would like to join to Jiris statement, ovirt should become more
stable, clean and useful.
The right or left clicks  or UI designs, mobile friendly or not,those
futures are the secondary tasks for me.
For those who would like to manage the vms from the mobile devices
they can use mOvirt app.
I wish that the development team will concentrate on the main
advertised futures to make them stable.
as a user I wish that the following points can make it stronger:
- please make a ovirt as a  FULL HA solution
- one of the weak points of the ovirt is a spm, this should go away in
the first point, not the right click one:).
- hosts management like a foreman, but without foreman.
- strong solution with a multirail HA storage
- move hosts complete to disk-less infrastructure, easy to scale-up
- scheduled backup solution integrated in the gui/api
- reasonable reports,( similar like dwd in 3.6)
Most of the points are almost done, but we have always hire or there
half-solved problems.


Greetings from Potsdam,
Arman.

 Short answer: No, we removed it on purpose.

 Long answer: No, here are the reasons why:
 - We are attempting to get the UI more mobile friendly, and while
 its not 100%
 there yet, it is actually quite useable on a mobile device now.
 Mobile devices
 don't have a right click, so hiding functionality in there would
 make no
 sense.

 - We replicated all the functionality from the menu in the

 We traded an extra click for some mouse travel

Re: [ovirt-users] Sync two Nodes

[Arman Khalatyan]

Yes, if you configure the cluster with networks /storage/etc  you can
put off the second node to save power:) and loose HA, but every time
when you change some thing in a  main node  you should turn on second
one and reinstall it.
Healthy node means that ovirt-engine can see that host has a access to
storage and all networks are available in order to start the failed
VM.
The HA function can be configured per VM, and the action what engine
should trigger on failure: reboot, pause or poweroff you can choose in
the vm settings.

[ovirt-users] oVirt management has lost its SSL.

[~Stack~]

Greetings,

OS: Scientific Linux 7.4
oVirt: 4.1
Everything fully updated.

Everything was working great. I received my new network card today to
upgrade my ovirt management node (physical node; not self-hosted), took
the machine down, swapped the card, and brought it up to many many errors.

Here's the basic break-down of my discoveries.

1) My /etc/pki/ovirt-engine/.trustedstore was corrupt. I had lots of
messages in my engine.log about it being corrupt. Restored from backup,
and oVirt engine was really peeved for not having my domain cert in it
(tons of messages in the engine.log file)...figured out how to add my
domain cert and it seemed OK. Which led me to...

2) My /etc/pki/ovirt-engine/keys/engine.p12 and
/etc/pki/ovirt-engine/keys/apache.p12 are _gone_. Don't have them in my
backups either. This results in a massive java dump when I try to start
the engine service.

3) I noticed that I had
/etc/pki/ovirt-engine/keys/engine.p12.201711021302 which is a time stamp
corresponding to when I shut the node down. Then I noticed, that I was
missing dang near EVERY file in /etc/pki/ovirt-engine but I had an
equivalent file with the ".201711021302" extension. So a touch of bash
and I copied all of my "*.201711021302" files with the proper
user/group/permissions into their base name. Hooray! No more errors in
the log files and all services start!!

4) I open my web browser and head to my management host...and I get this
error:
Keystore was tampered with, or password was incorrect

Well...yeah. I had to fix it in step one. :-/

I'm not getting anything useful out of my Internet searching. I don't
know what went wrong or why, but my SSL is just borked.

Any suggestions? Thoughts? Ideas?

Is there a way to just blow away and start over with the SSL _without_
destroying the VM's (which fortunately they all seem to still be
functional!)?

Any help would be greatly appreciated.
Thanks!
~Stack~

I'm using right click time to time, but for me is much more important
clean, simple and compatible UI. Especially if this means it will be
possible to simple select and copy any text or log messages from UI.
This is my biggest pain when interacting with manager.

Re: [ovirt-users] Start ovirt-engine in another node.

The image is in storage. I don't have backup because it was recently
migrated. I have a task to make backup system on the next week.
I just need to start in another node.

I have 5 servers with workload balance enabled and HA. The second node
suddenly restarted and I lost control of my cluster.

The ovirt does not contain any sync / HA functionality in the data side.
Maybe you are looking for some ha/failover-file systems like a

When I understand your right, then there is no necessary data on the

When one node crashes I can just migrate the VM to the second node? That

[ovirt-users] Sync two Nodes

[Jonathan Baecker]

Hello everybody,

I would like to sync two nodes, but I want that only one node runs 
permanently. Only once a week or a month I want to start the second node 
and sync them again, if this is necessary.


What you would recommend for this scenario? oVirt have a HA functions, 
what I could use, but I thought oVirt brings then maybe errors when one 
node is always off. I'm wrong here? Or is there other options what works 
better?


Have a nice day!

Jonathan

Re: [ovirt-users] oVirt Node 4.1.6 on IBM x3650 M3

[Jonathan Baecker]

Hello Yuval,
sorry for my late response! I installed from a USB stick... I try it now 
again on a second machine and the exact message is:


   *Failed to open \EFI\centos\grubx64.efi - Not Found**
   **Fail to load image \EFI\centos\grubx64.efi - Not Found**
   **start... image() returned Not Found*

What Brian Barry recommend didn't work for me to. I booted again from 
the stick and choice Troubleshooting, there I can select "1", this 
should mount my installation to a folder, but the starting process ended 
up in a loop, where error comes up saying something about error on line 
9. After a second round I lost my patience and I install again the 
normal centos minimal.


Is there any performance benefit with installing from oVirt Node?

Regards
Jonathan

We did have some problems in the past with efi, but they should be

Did you use the ISO for installation ?  What error are you seeing - 
which file is missing there ?


Thanks,

Yes, I use power management with ipmilan, no issues.

I do have license on the IMM for remote console, but that is not a

I remember I first tried to use for oVirt a dedicated login on

with just "Remote Server Power/Restart Access" and I could not

work, so I just granted "Supervisor" to the dedicated login.
Other than
that, no problem.

What is the *proper* way. Cause I've come across quite a few different ways
reading on this how to get it done. Some say do it by hand, others say
never do it by hand use the vdsClient, others say do it this way. I mean
between forum posts, blogs, it seems there are multiple ways to do this.

Thanks for sharing your experience, Darrell.
I'm testing some VMs with Oracle RDBMS where I configured 3 disks with
virtio-scsi and now I have assigned 3 IO threads. Let's see the numbers.
In the mean time I verified you have to deactivate/activate the disks in
the guest, otherwise you do get 3 SCSI controllers, but all the 3 disks are
bound to the first one (scsi0-0-0-0).
Now instead on hypervisor I correctly get this with dumpxml:

# virsh -r dumpxml my_guest | grep scsi
  
  
  
  
  
  

  

  

  
#

Martin, I have not understood when you write about "if you have multiple
storage devices across different NUMA nodes."
Can you elaborate a bit or point to any documentation link?

Thanks,
Gianluca

[ovirt-users] Host in kdumping state

[Davide Ferrari]

Hello

I've got a faulty host that keeps rebooting itself from time to time 
(due to HW issues), that is/was part of the 3 hosts group hosting the 
HostedEngine, and now it always appears as "Kdumping" in the web 
administration panel.


All my hosts are oVirt 4.1 on Centos 7.3 with glusterfs 3.7 but this one 
that was updated by mistake to Centos 7.4 with glusterfs 3.8.


Is this due to the different OS/gluster version? How can I "reset" it? I 
want to remove it permanently and assign the HostedEngine to another host?


Moreover, the main glusterfs volume, the one which holds the HE image, 
has some bricks on this failing machine (vm03):


#  gluster volume status data_ssd

What's the best way to replace them? Is this guide still useful?
