[ovirt-users] ovirt 4.2.2-rc3 switching from legacy to OVS..

[Thomas Davis]

I'm getting further along with 4.2.2rc3 than the 4.2.1 when it comes to hosted 
engine and vlans..  it actually does install
under 4.2.2rc3.

But it's a complete failure when I switch the cluster from Linux Bridge/Legacy 
to OVS.  The first time I try, vdsm does
not properly configure the node, it's all messed up.

I'm getting this in vdsmd logs:

So something is dreadfully wrong with the bridge to ovs conversion in 4.2.2rc3.

Doh! Problem solved. Well at least I found it on my own...

Date on server is wrong, and certs were silently failing.

Hi Yaniv,

To give an example, We are planning to create and manage our VM's using
oVirt.
Instead of managing oVirt using UI, We will be writing the script which
hits the oVirt engine periodically for different functionality.


May I suggest Ansible, or any of our SDKs?
It'll surely make your work more productive and quite likely higher
performance (as it's already quite built for performance, with pipelining,
multiplexing, compression and connection management).

so We would like to take a benchmark to finalise the number of hits to
ovirt.


Hits for which functionality exactly?


This is what we are trying to achieve.


I suspect you focus too much on synthetic benchmark rather than a real use
case.
Y.


Coming to my query,
What is the difference between sso token and session maintance in oVirt, If
I have a token timeout of 4 days, How the concept of session plays a role
in oVirt?

Thanks,
Hari

Hi,

If you are looking for VM image backup, you may have a look at Open Bacchus 
https://github.com/openbacchus/bacchus

Bacchus is backing up VMs using the oVirt python api and final image will 
reside on the Export domain (which is an NFS share or glusterfs) in your 
environment. It does not support moving the images to tapes at the moment. You 
need to use another tool to stage your backups to tape.

Hope this helps.

[ovirt-users] How to force remove template

[John Nguyen]

Hi Guys,

I apologize if you may have addressed this earlier.  I have a template in
an odd state.  The template show it's disk on one storage domain, but in
actuality the disk is on a different domain.  I would like to delete this
template since its not in uses and out of date.  However when I try, I get
the error "image does not exit in domain."

Is there a way to force remove a template from the database?  Any thoughts
would be greatly appreciated.

Thanks,
John

Re: [ovirt-users] Limitation in using Ovirt SSO Token

[Hari Prasanth Loganathan]

Yes, we will take a SSO token using SSO auth Rest API call and use the same
token for all the API hits for next 4 days (Example If 4 days is the SSO
token timeout). Is there an issue with using like that?

If there is a session concept there for SSO token in using as Rest API?

Re: [ovirt-users] Limitation in using Ovirt SSO Token

[Hari Prasanth Loganathan]

Hi Yaniv,

To give an example, We are planning to create and manage our VM's using
oVirt.
Instead of managing oVirt using UI, We will be writing the script which
hits the oVirt engine periodically for different functionality. so We would
like to take a benchmark to finalise the number of hits to ovirt.

This is what we are trying to achieve.

Coming to my query,
What is the difference between sso token and session maintance in oVirt, If
I have a token timeout of 4 days, How the concept of session plays a role
in oVirt?

Thanks,
Hari

Hi Team,

I would like to know, Is there any limitation in using the same sso token
for multiple request.


Are you reusing it or abusing it? Are you actually using it in a single
session, to avoid reauthentication, or just sharing between multiple
sessions? While I'd still would not want to see the engine affected by such
abuse, the latter is quite atypical use case.

Can you share engine and server logs?

And again, it'd be very helpful if you could share what you'd like to
achieve and we'll gladly assist.
Y.


I observe that when I use the same sso token for more than 900 HTTP Rest
request, the application went down. Is there any limitation in using same
SSO token? I could see that my status is showing as ACTIVE and memory and
CPU seem fine. Still, the oVirt is not reachable and I need to restart it
to access again.

[ovirt-users] Limitation in using Ovirt SSO Token

[Hari Prasanth Loganathan]

Hi Team,

I would like to know, Is there any limitation in using the same sso token
for multiple request.

I observe that when I use the same sso token for more than 900 HTTP Rest
request, the application went down. Is there any limitation in using same
SSO token? I could see that my status is showing as ACTIVE and memory and
CPU seem fine. Still, the oVirt is not reachable and I need to restart it
to access again.

Re: [ovirt-users] Very Slow Console Performance - Windows 10

[FERNANDO FREDIANI]

Hello Gianluca.

As I mentioned previously I am not sure it has anything to do with SPICE 
at all, but with the amount of memory the VM has assigned to it. Proff 
of it is that when you access with via any Remote Desktop protocol it 
remains slow as if the amount of video memory wasnt being enough and 
have seen it crashing several times as well.

Resurrecting this topic. I made the changes as per your

don't think is necessary to do any changes on the hosts right ?


correct on both



Hello Fernando and Michal,
at that time I was doing some tests both with plain virt-manager and 
oVirt for some Windows 10 VMs.

More recently I haven't done anything in that regard again, unfortunately.
After you have done what you did suggest yourself and Michal 
confirmed, then you can test powering off and then on again the VM (so 
that the new qemu-kvm process starts with the new parameters) and let 
us know if you enjoy better experience, so that we can ask for 
adoption as a default (eg for VMs configured as desktops) or as a 
custom property to give



On the recent updates has anything changed in the terms on how to
change the video memory assigned to any given VM. I guess it is
something that has been forgotten overtime, specially if you are
running a VDI-like environment whcih depends very much on the
video memory.


there were no changes recently, these are the most recent
guidelines we got from SPICE people. They might be out of date.
Would be good to raise that specifically (the performance
difference for default sizes) to them, can you narrow it down and
post to spice-de...@lists.freedesktop.org
?



This could be very useful too

Cheers,
Gianluca

Yes, I see that there are some VSS events intercepted in event viewer when
I run a snapshot.
But in my particulr case I have an Oracle database used for Business
Intelligence that for performance reasons is not in archive log mode, so it
can't interact with VSS layer.
Due to its nature I can shutdown this database during the evening and then
reopen it before the ETL processing happens during the night.
So in that time frame I would like to have a pre-snapshot operation of
shutdown db and post-snapshot operation of start db.
And then I clone the snapshot and export it in case I have to restore the
"blob" as a consistent whole

It is for this reason that I'm trying to verify if the freeze-hook is
usable also in WIndows environments (based on some threads I find it should
be...)

Gianluca

Re: [ovirt-users] Tunable parameters in ovirt engine

[Hari Prasanth Loganathan]

Hi Juan,

Now we got a clue, I try to hit 100 concurrent request in which 1 request
got failed with the 503 error, I observed this in apache ssl_access.log

172.30.36.167 - - [08/Mar/2018:17:22:42 +0530] "GET /ovirt-engine/api/vms/
HTTP/1.1" 503 299

Is it thrown from Apache / ovirt engine?

 Could you let me know the configuration of Apache web server is correct?

Re: [ovirt-users] Ghost Snapshot Disk

[Lionel Caignec]

Hi,

i finished to move my data, but now when i want to remove my old disk i get 
stuck to this error : 
"Cannot detach Virtual Machine Disk. The disk is already configured in a 
snapshot. In order to detach it, remove the disk's snapshots". 
But like i said before there is no snapshot anymore.
So what can i do? Delete manually inside database? So where?
Delete manually lvm volume, so how can i find the good one?

Please help ;).

Hi Lionel,

Sorry for the delay in replying you.

If it's possible from your side, syncing the data and destroying old disk
sounds about right.

In addition, it seems like you're having this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1509629
And it was fixed for version 4.1.9. and above.



*Regards,*

Re: [ovirt-users] Tunable parameters in ovirt engine

[Juan Hernández]

I think the configuration is good. There may be some connections that 
the server is closing before the client expected, but that is normal, in 
my opinion.

I googled it and found that it is due to the connection drop. So It would
be Great, If you could check my Apache server configuration I shared in the

Hello,

you select the vm disks you want to move and with the right click you
select the menù entry "Move". You'll get a windows asking for the
destination storage domain.

Once set the values, you confirm and disk will be moved.

Re: [ovirt-users] Tunable parameters in ovirt engine

[Hari Prasanth Loganathan]

This is the only error message we received from ab.

I googled it and found that it is due to the connection drop. So It would
be Great, If you could check my Apache server configuration I shared in the
thread and let me know your thoughts on this.

Thanks,

Because there are some operations (lvm initialization & so on) to be

I supposte that your question is related to the way that FC is
managed. Since every host sees all the drives, there question is no
more appropriate.

Sure, nfs storage domain or fc storage domain doesn't make difference
in terms of interaction. You can move disks from one to the other
without issues.

[ovirt-users] Fibre Channel Protocol (FCP)

[maoz zadok]

Hello All,
I connected existing data center with NFS storage domain to a new
Fiber-Channel storage domain according to the following guide, and I have
three questions.
https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storage/

1. why does the storage domain asks me to "Use Host"?

   - does it mean that if this host is down there is no access to the FC
   storage or the next available host elected to manage the FC storage?
   - does it mean that all the traffic to my storage is routed via the
   selected host?
   - what is the best practice, do I need to split the workload to other
   hosts as well by letting each host manage one small LUN instead of letting
   one host manage all LUNs or one big LUN?

2. is it possible to set the newly created fiber-channel storage(data
domain) as master?

3. can I easily migrate all VM disks to the FC storage instead of the NFS?

Thank you!

It's not clear to me why it's urgent.
Please look at past replies and provide more information so we can assist

Hi , this has now become really urgent.

Everything I try, I am unable to get the Cluster Compatibility Version to
change.

The entire platform is running the latest 3.6 release.

Windows is somewhat different. In fact, it's a bit better than Linux (ARGH!
but it's true) with its support for VSS - an API for applications to
register to events such as backup.
You should have the QEMU guest agent VSS provider installed (Note: need to
see where's the latest bits - I found[1]).

Then, if your application supports VSS, you are all good (I believe).
