Re: [ovirt-users] ovirt ansible module

[Oved Ourfali]

The VM leases feature is a new feature in 4.1, and I'm not sure whether it
was included in the ansible modules or not.
CC-ing Ondra as he will know for sure.

Re: [ovirt-users] How to enable tunnel migration

[like...@cs2c.com.cn]

OK. Thanks. I filed a bug https://bugzilla.redhat.com/show_bug.cgi?id=1430198

The software stack as follows:
OS: RHEL7.2
Libvirt: 1.2.17-13.el7_2.5
Qemu-kvm-ev: 2.3.0-31.el7_2.23
ovirt-engine: 3.6.7.5
vdsm: 4.17.32-2

BTW, i'm wondering why there is no place to enable tunneled migration feature 
on the WebUI.

The installation is of 1 week. Normaly it should have collected the data by

Re: [ovirt-users] Problems adding iSCSI storage domain

[Pavel Gashev]

Actually you have added the storage, but it’s not attached to your datacenter 
so you can’t see it your cluster.

1. Select System (root) on the tree at the left
2. Select Storage tab. Now you should able to see your storage as Unattached
3. Select your storage, and then Data Center tab
4. Attach your storage to a datacenter

"*Important:* If more than one path access is required, ensure to discover

This is from the oVirt admin guide, did you discover and login to all the

You can manually delete the domain from the database.  Run a backup
first though.

Re: [ovirt-users] 3.5->3.6 did not import hosted engine storage domain

[Michael Watters]

Can you configure a *new* cluster and migrate the engine to that? You
should be able to import your existing storage domains and logical
networks under the new cluster which can then be used as a migration
target for any running VMs.  Your other option would be to build a new
engine using 4.0 and then restore your 3.6 backup.

Hello I have got Dell MD3820i and four interfaces which was connected to

But there is only one IP which I can set during the configuration of iSCSI
RHV storage.
Everything has been fine until I pluged off cable from the storage NIC
interface with IP configured in the RHV iSCSI section.

Now VDSMD got problem because it tries to connect via iscsiadm with exact
IP and does not use the configuration from the /var/lib/iscsi/, where are
tree extra paths to achive the LUN. In multipath -ll I see an active path,
of course with the second storage interface IP

Is this a new installation? The odds are highly likely that for whatever 
reason (being a new installation would mean the data is not there) the DWH

will rotate the missing data out and eventually the 24 hours worth of data

The cloud connector[1] of CF uses Fog[2]. oVirt Fog support uses the old
Ruby SDK, which will be an issue for us.
AFAIK, this is the same way that Forman / Spacewalk is talking to oVirt, so
we need to think how we can update our support there.
We should add it to our GSoC or outreachy projects: update our Fog support
to use the official Ruby SDK.

Re: [ovirt-users] OVirt new cluster host only logins on one iSCSI

[Duarte Fernandes Rocha]

Hi,

Could it be because of this:

/http://www.ovirt.org/documentation/admin-guide/chap-Storage//[1]

Adding iSCSI Storage
...
Important: If more than one path access is required, ensure to discover and log 
in to the target 
through all the required paths. Modifying a storage domain to add additional 
paths is currently 
not supported.

It's true that the second iscsi path was discovered later, and on the host1 I 
am not able to put 
on maintenance to check if both iscsi sessions are disconnected, but according 
to that 
documentation it is not currectly suported. Is there a way to do it without 
removing the storage 
and importing it again (this is not an option at this point..)?

Your words may me think that you believe that there is an standard REST
API that VMware and OpenStack both implement, and your question is if
oVirt implements it as well. But that isn't correct, VMware and
OpenStack have different REST APIs, and so does oVirt. Cloud Foundry can
talk to the VMware and OpenStack APIs, but not to the oVirt API, as far

[ovirt-users] DWH reports in 4.X ?

[Eduardo Mayoral]

Hi,

I see the DWH reports disappeared in 3.5 or maybe 3.6, there seems
to be no substitute por 4.X

Is there some alternative to have some pre-made reports from the DWH
on 4.X ? Maybe not something on the oVirt project itself but from
someone on the community?

Thanks in advance!

The reason there is no status there is that in oVirt there is no
cluster status (look at the cluster main-tab, for example).
We only have statuses for objects like DCs, Hosts, VMs, SDs
(well, maybe we have for some more, but not clusters...).
We decided to include clusters in the inventory part anyway, for
user visibility, and provide access to the clusters main tab by
pressing the link.

 1. On the lower part at "Cluster Utilization" and "Storage
Utilization" we don't have any information at all.

Where does this information come from? DWH service is up and
running

The inventory part is taken from the engine.
All the rest is taken from DWH.
You can start with sharing the engine logs here.
Shirly - any other logs or information you think is required?

Where do I have have to investigate further to find out what
is missing/not working?

Let me know if you need further information.

Re: [ovirt-users] Graphics are turned upside down when install QXL in Windows

The issue with Spice HTML5 is as old as native client for MacOS(X). Both are 
not maintained well.

That´s a real shame, IMO it´s awesome to not have a native client that
you have to maintain for every platform. I think it works great, and
being platform independent is super!

That´s a real shame, IMO it´s awesome to not have a native client that
you have to maintain for every platform. I think it works great, and
being platform independent is super!

I agree. I think if you could send a patch to fix this and maintain the client, 
that'd be awesome ;-)
(There might have been fixes to this issue - I know people tried, but I'm not 
up-to-date wrt the latest status of that client).

Nice try Y, I would if I could:)

What I meant is that if resources was diverted from maintaining several
native clients to one browser client, that could be a win, having less
to maintain.

[ovirt-users] oVirt 4.1 Dashboard

[Arsène Gschwind]

Hi,

I've update our oVirt installation 3.6 --> 4.0 --> 4.1, everything went 
smooth except update some of the hosts which i could update after 
several hour playing around.


We greatly appreciate the dashboard in 4.1 but we see the information 
missing:


1. On the cluster block in the upper part we see the amount of clusters
   but no Status (N/A)
2. On the lower part at "Cluster Utilization" and "Storage Utilization"
   we don't have any information at all.

Where does this information come from? DWH service is up and running

Where do I have have to investigate further to find out what is 
missing/not working?


Let me know if you need further information.

Rgds,
Arsène

Re: [ovirt-users] oVirt Nodes Monitoring

[Arsène Gschwind]

Hi Fernando,

We do monitor our oVirt hosts using Zabbix and we add the zabbix repo to 
the host so we keep it up to date.


rgds,
Arsène

Hi.

How do you guys monitor your hosts with Zabbix ?
I see the oVirt Nodes have snmpd service installed and could be used 
for basic things but ideally, for Zabbix is good to use its agent.


What would be the best way to install its zabbix-agent package and 
make it persistent ? Add its repository to the oVirt-Node in 
/etc/yum.repos.d/ and install it with yum or install using a .rpm 
directly ?


Thanks
Fernando

Hi,

I added the LICENCE file [1] to the project.

Hi,

I implemented a storage domain balancer [1], i.e. a script that
tries to
keep all storage domains under a defined threshold. We use our
oVirt
infrastructure for teaching so have several hundreds of users and
cca.
800 VMs at this time, so something like this is really needed
considering that when students create their VMs they tend to create
their disks under the same storage domain (normally the first
available
one). This results in one or two heavily used SDs and the rest
underused.

I tried to keep it as simple as possible and doesn't have many
features,
but it seems to work (I tried it under our conditions: About 10
SDs,
relatively highly used). If someone want to improve something on
it,
pull requests are welcome.

Might also be an inspiration on [2].

That´s a real shame, IMO it´s awesome to not have a native client that
you have to maintain for every platform. I think it works great, and
being platform independent is super!

Known issue with the Spice HTML5. We should drop it, it's not being very
well maintained.
