Re: [ovirt-users] [3.6] User can't create a VM. No permission for EDIT_ADMIN_VM_PROPERTIES

[Maksim Naumov]

As I was able to understand this error mean that user tried to rewrite the
destination host of VM. But the problem is that there is no setting like
this in the user interface. User can't change the destination 100%. It is
not hardcoded in the template settings because he was trying to run Base
template (which is not attached to any host).

Thanks for the report!

Please open a bug about this, attach relevant logs (including engine setup
logs and yum.log), and try to describe the exact flow leading to this.

 Hi,

 At some point I had the oVirt reporting configured on my engine and it
 worked. I had a "reports" option in the menu and could generate
 reports for various resources.

 At some point I've noticed that the "reports" option was no longer
 there but did not have time to investigate. I believe it happened when
 I migrated the engine host from CentOS 6 to 7 using engine-backup and
 restore.

 How can I debug this?

 In the ovirt-engine-dwh log I used to see the following error:

Quick search suggests that it works:

Some features require guest agent, which is probably not available for OS X,
but I guess it is possible to port the ovirt-guest-agent to OS X.
Yeah it's not available at this point. Some things might work out of the

However the biggest problem for the port will be the VirtIO support

You got it mostly right.

Did you have a look at [1]?

The engine is the process that manages the whole thing. It exposes an admin
interface (web+api), monitors the hosts and VMs, etc.

A host and node are where VMs run. In many cases these terms are
interchangeable,
although usually "node" is a host installed with the ovirt-node image, whereas
an "ovirt host" is a host installed with a "normal" OS and later provisioned to
be used (by installing stuff on it, usually using the "New Host" wizard in the
web ui).

I assume you refer to 3.6, released a few weeks ago.

The release notes page [2] does mention specific versions of fedora
and el. I agree
it could be written more clearly. The Download page [3] lists them too.

3.2.1? Where is this one referenced?

RN [2] has a section "ovirt node" with links to pre-release (has
ovirt-node-iso-3.6-0.999.201510221942) and final (still empty).

Not sure I fully understand. ovirt node includes its own OS, and IIUC we only
ship one based on el7. Technically it's probably possible to build one with
fedora, never tried that.

Architecture [1] above does have some text about that, and links at [4] which
has more.

Some more info:

Generally speaking, and until 3.5, storage was separated from what we call
"compute nodes" (those running VMs). You can bring your own external storage,
be it a mere linux machine serving its disks through nfs/iscsi/etc., or some
"dedicated" storage boxes (netapp/emc/etc.). You can also use gluster. The
engine also manages gluster storage. In 3.6 there was some work to allow
using the same hosts for both. Some of it was finished, some postponed
to 4.0. You can check e.g. [5][6].

Re: [ovirt-users] Delete disk references without deleting the disk

Hi Nir,

I wonder if it can be made any more efficient, I think this method is clear
enough. The only thing not clear to me was that while deleting the storage
domain, it doesn't touch it's contents.

[ovirt-users] Greetings and observations from an oVirt noob

[Kenneth Marsh]

Hello all,

I do development operations for a part of a software division of a large
multinational. I'm an experienced user of VMWare and Amazon AWS, soon to be
pushed onto Azure, and I've found a common thread among all solutions -
they are all expensive enough that my budget will certainly not be approved
with them. I'm deferred to the IT part of the organisation, which operates
too slowly and inefficiently (in terms of both cost and time) for my
requirements. This is what led me to RHEV, and ultimately to oVirt. This is
a feasibility study for what may ultimately be a RHEV-based data center in
a new office, and if I succeed we will be doing more on a fixed budget by
using more RHEV and less Azure.

I spent the weekend working with oVirt and I'm very impressed. I had no
idea such a comprehensive enterprise-class solution was even available.
Being a complete newcomer, I started without a clue and after a weekend had
set up a nearly-working data centre including an oVirt hypervisor node, all
on old Dell notebooks loaned to me temporarily by our IT group. I started
with RHEV but decided to use oVirt for two reasons - one being to see
what's possible with the latest and greatest, the other because RHEV
required some licensing I've not yet purchased. Long term it'll have to be
RHEV for enterprise support reasons I'm sure many are familiar with.

There are a few things I found, from a newcomer's perspective, very unclear.

   - What is oVirt, vs oVirt engine, vs oVirt node, vs oVirt host. Try to
   find documentation on any of these and get spammed with references to the
   others. I think I've worked out that these are the collective suite of
   products, the management centre, the bare-metal hypervisor, and
   participating member servers, respectively.
   - Which versions of CentOS/Fedora/oVirt Node are compatible at which
   oVirt compatibility level? This would normally be addressed in the release
   notes. It was also confusing to discover oVirt node 3.2.1 is compatible at
   the 3.5 level. The answer to this remains unclear but I'm trying to use
   Fedora 22 across the board now with oVirt node 3.2.1 and this seems to be
   working, although I haven't gotten a server node into a cluster yet, only
   oVirt nodes.
   - Storage domains - much doco about them being needed and how to
   configure them but nothing about what they are or why they are needed. I
   would have expected an oVirt node to be capable of both data and ISO
   storage but apparently there needs to be an NFS or iSCSI filesystem there
   first? And there's local storage vs shared, another concept much talked
   about how to prepare and add it but not explained why one would want to do
   that or what it means.

I think with further internet combing and by trial-and-error I'm very
likely to figure it all out. I hope all goes well and implement this stuff
in our new data centre and then I'd be keen to contribute some of my own
tech writing.

Meanwhile, I hope to be active on this mailing list and I thank everyone in
advance for sharing their oVirt experience. For any who are looking at the
doco thanks much for the plethora of stuff out there already and I hope the
above bullet points help you understand where doco most needs more
attention. At least from the perspective of one who has just come across
oVirt.

deletion. What I want to do is delete the VM's including disks without
actually deleting the disk images from the storage array itself. Is that
possible? At the end I want to be able to delete the storage domain (which
then should not hold any data, as far as ovirt is concerned).

Reason for this: it's a ZFS pool with dedup enabled, deleting the images
one by one will kill the array with 100% iowa for some time.

Hi John,
sorry for the delay.

We have several options.
How are you with writing Java code?

Hi
You are probably trying to set the list of hosts dedicated to run this VM or

For those you must be administrator

Re: [ovirt-users] report option gone missing

[Shirly Radco]

Hi Rik,

The ovirt-engine-dwhd process is responsible for collecting the data from the 
engine to the oviry_engine_history database where samples data is stored and 
then aggregated to Hourly and daily.

If this service is running and there are no errors in the log then you should 
be able to see up to date data in the statistics tables in the history database 
(They end with samples/hourly/daily).

Please check these table are up to date.

http://www.ovirt.org/Ovirt_DWH


The ovirt-engine-reportsd is the service of the reports server. If it is 
running and it is configured with a FQDN you should be able to log in through 
http://FQDN:8090/jasperserver/

If you want to remove the reports you can just run 

$yum remove ovirt-engine-reports 

and run 
$ engine-setup

and when you install it again 
$ yum install ovirt-engine-reports 

run again 
$ engine-setup 

to configure the reports.


http://www.ovirt.org/Ovirt_Reports

Please let me know how it goes.

Select the vm, click "remove", in the confirmation dialog, uncheck the
"Delete disks"
checkbox, confirm.

Ovirt deleted the vms, but is keeping the disks, so the storage domain
does hold all
the disks.

So what do you need is to destroy the storage domain, which will
remove all the entities
associated with it, but will keep  the storage without any change.

Do this:
1. Select the storage tab
2. select the domain
3. In the data center sub tab, click "maintenance"
4. When domain is in maintenance, click "detach"
5. Right click the domain and choose "destroy"

This will remove the storage domain from engine database, leaving
the contents of the domain.

You can now delete the contents using favorite system tools.

Now, if we want to add support for this in ovirt, how would you delete
the entire domain in a more efficient way?

Re: [ovirt-users] report option gone missing

[Rik Theys]

Hi,

I was able to resolve my issue by adding the reports.cer file to the
/etc/pki/ovirt-engine/.truststore file. It seems the certificate got
updated by an engine update but was not added automatically to the
truststore.

Regards,

Rik

Hi,

I was able to login on the ovirt-engine-reports web application as

What is the procedure to fully remove the reporting from the system and
start anew? Will a remove of the package automatically clean up the

Hi,

At some point I had the oVirt reporting configured on my engine and it

At some point I've noticed that the "reports" option was no longer
there but did not have time to investigate. I believe it happened when
I migrated the engine host from CentOS 6 to 7 using engine-backup and

How can I debug this?

In the ovirt-engine-dwh log I used to see the following error:

But after rebooting the engine host it now only lists 'Service Started'.

The ovirt-engine-reportsd is also running.

Which of these two processes (reportsd vs dwhd) is generating the
reports (and showing it in the engine admin interface)?

In /var/log/ovirt-engine-reports, the reports.log file is empty, the
server.log reports Deployed ovirt-engine-reports.war as the last line
(without any obvious errors). Only jasperserver.log shows:
