Perhaps start by reading the readme file of the site:

https://github.com/oVirt/ovirt-site

and continue with "CONTRIBUTING.md" and "MAINTAINING.md" there.

If you are new to git/github, you should probably read about them too,
although for simply editing the web site the basics should be enough.

Feel free to ask any questions - perhaps on de...@ovirt.org instead of
here. Welcome and good luck!

Re: [ovirt-users] unhappiness with ovirt engine after upgrading file server handling storage domain

[plysan]

did you restart your nfs service or reboot your nfs host during the upgrade
progress ?
if you did, what's the webadmin portal's storage domain's status at the
time ?

what i'm suspecting is that you were restarting nfs while ovirt-engine is
using it.

Re: [ovirt-users] Docker images for oVirt engine

Checked it out. It seems more complicated than what I need, which
would be just a Dockerfile that pulls the required image. The
ovirt-containers repo seems to have a dependency on OpenCluster, which
I think I won't need since I'm after a basic install on one machine
for documentation purposes. Your advice is appreciated.

Hello,

I can create quotas with the SDK ( python) and make a user a 
consumer of the quota in the admin portal but don't know how to do it with the 
SDK or API.


Any help appreciated.

Hi Juan,

Currently we are seeing the lag/delay in the VM's. The slowness comes from 
when we access applications from the network vs. locally.  For instance 
Putty opens quickly when run locally, but when run from the network it may 
take a minute or so to launch.

I am watching the Nload graph on the physical server and not seeing 
any/minimal traffic go out on the vlan the vm is running on.

Currently my bonding options are setup as follows:

BONDING_OPTS='mode=4 miimon=1'

I will be changing the options to:
mode=4 miimon=100 xmit_hash_policy=2

[ovirt-users] Do we have to update ovirt to import storage domain?

[wodel youchi]

Hi,

We have a test environment build on ovirt 3.5 and now we have installed a
new platform build on ovirt 4.1 and we want to import the test VMs into it.

The question : do we have to update the test environment to be able to
import the vms?

If yes, to what version do we have to update? The minimum version needed

[ovirt-users] unhappiness with ovirt engine after upgrading file server handling storage domain

[Jason Keltz]

Hi.

I recently upgraded my oVirt infrastructure to the latest 
4.1.1.8-1.el7.centos, which went smoothly.  Thanks oVirt team! This 
morning, I upgraded my NFS file server which manages the storage 
domain.  I stopped ovirt engine, did a yum update to bring the server 
from its older CentOS 7.2 release to CentOS 7.3, rebooted it, then 
restarted engine.   At that point, engine was unhappy because our 4 
virtualization hosts had a total of 30 VMs all waiting to reconnect to 
storage.  The status of all the VMs went to unknown in engine.  It took 
almost 2 hours before everything was completely normal again.  It seems 
that the hosts were available long before engine updated status.  I'm 
assuming it's better to restart engine when I know that NFS has resumed 
on all the 30 virtalized hosts.  However, it's hard to know when that's 
happened, without trying to connect manually to all the hosts.  Is there 
a way to warn engine that you're about to mess with the storage domain, 
and you don't want it to do anything drastic? Sort of like a 
"maintenance mode" for storage?I would hate for it to start trying 
to power off hosts via power management or migrate hosts when it just 
needs to wait a bit...


Thanks!

Re: [ovirt-users] unable to set group on volume

[Joel Diaz]

I though I would try something different so I removed the key group and
value virt when creating the volumes. I was able to create the volumes. I
stopped the data volume. I then tried to set the volume group by issuing a
"gluster volume data group virt"

Still get "unable to open file '/var/lib/gluster/Virt'. Error: No such file
or directory.

I don't know if I should continue with the setup until I can set this value.

Please let me know if I can provide some logs to identify the issue.

Thanks for your help,

Joel

The file is empty. I created the file by issuing a "touch
/var/lib/glusterd/groups/virt"

The first time I attempted to set the group volume, the error was that the
file was missing. I read a bug report that advised to remove and reinstall
the gluster package in order to properly recreate the file. Since that did
not work, I created it manually.

Thank you,

[ovirt-users] Network Performance

[Bryan Sockel]

I am doing some testing with our current ovirt setup and i am seeing some 
lagging going on when i attempt to launch or access files from a network 
share, or even run windows updates.  

My current setup is 4 X 1 GB Nic bond with multiple Vlan's attached.  Server 
usage is currently low. I have also not setup any additional Network QoS and 
everything else is set to default.

My answer would be definitely.
If you are volunteering, you would be very welcome.

That one is obsolete AFAIK. The oVirt container images are now being
worked on in the 'ovirt-containers' repo.

GitHub generally contains a read-only mirror on the oVirt sources,
development work for most projects is done via gerrit.ovirt.org.

[ovirt-users] Docker images for oVirt engine

[Leni Kadali Mutungi]

I noticed that there had been some discussion regarding Docker images
in the devel mailing list. I wanted to confirm that this:
https://github.com/oVirt/ovirt-container-engine is alright to use with
Docker. If this isn't the official source to use, pointers in the

Re: [ovirt-users] Building ovirt-host-deploy gives `configure: error: otopi-devtools required but missing`

[Leni Kadali Mutungi]

Sorry for the silence. I've been doing some tinkering. I did what
Jason did i.e. `./configure --enable-java-sdk --with-maven
--with-otopi-sources=/home/user/otopi` since that's where I had
checked out otopi. ./configure is able to locate where the
otopi-bundle file is (/usr/share/otopi directory for me) with the
options above. If you try to use the options `--otopi-bundle` or
`--with-otopi-bundle`, you'll get a unrecognized option from
./configure.

I then ran `sudo ovirt-host-deploy/src/bin/ovirt-host-deploy` at my
command prompt and got the same error as that which Jason got.
 # ./src/bin/ovirt-host-deploy

 hypervisor. Are you sure you want to continue? (yes/no) yes

 [ INFO  ] Stage: Environment packages setup

 [ INFO  ] Stage: Pre-termination

Difference being that I wasn't doing the compilation as root, I was
using sudo for elevated privileges. Looking at the log file, I saw the
following errors:
2017-05-07 07:21:37,011+0300 DEBUG

NotImplementedError: Packager install not implemented

So as a workaround, I used the instructions in the README to create a
file called /etc/ovirt-host-deploy.conf.d/50-offline-packager.conf to
suppress this reaction.
Contains the following instructions:

  [environment:init]
  ODEPLOY/offlinePackager=bool:True
  PACKAGER/yumpackagerEnabled=bool:False

This allowed it to run further than it did for Jason (and myself when
I tried it out). The new error message I got was:

Adding the 3 bricks to engine does not redistribute the data. You need to
run rebalance on gluster volume engine for this. There's a bug currently
that rebalance causes corruption when performed with ongoing IO on the
volume.
I think the best way for you to do this, is put hosted-engine to global
maintenance, stop the hosted-engine and rebalance the engine gluster volume.

What was the original size of the engine gluster volume? (Curious to
understand why you ran out of space)

The VMs running on data gluster volume should not be affected by this.

Ok, I understand, now.
You have few options here.
If you want for example only VMs from datacenter 'X', you can use following:

- hosts: localhost
  connection: local
  tasks:
  - name: Get VMs from datacenter X
ovirt_vms_facts:
  pattern: datacenter=X
  auth:
url: https://acore.v100.abes.fr/ovirt-engine/api
username: admin@internal
password: ovirt123
insecure: true
  - debug:
  msg: "{{ ovirt_vms | map(attribute='name') | list }}"

Yes, because the 'data_center' parameter isn't part of the VM type. Take a
look here[1],
you will find there all attributes the VM has. As you can see there is no
'datacenter', but
there is a 'cluster', but as said in documentation, it's just a reference
to the cluster. That
means that it contains the ID of the cluster and the 'href' to the cluster,
so you can get
the cluster object by following that reference using this code:

 vm_cluster = connection.follow_link(vm.cluster)
 print vm_cluster.name

 # Same for datacenter:
 vm_dc = connection.follow_link(vm_cluster.data_center)
 print vm_dc.name

What you need to understand is, what is the difference between the 'full'
object and the reference to the object. It's good to take a look at the XML
output of the API and learn to read the API specification documentation,
when working with oVirt Ansible and Python SDK.

Re: [ovirt-users] unable to set group on volume

[Joel Diaz]

Thanks for the reply.

The file is empty. I created the file by issuing a "touch
/var/lib/glusterd/groups/virt"

The first time I attempted to set the group volume, the error was that the
file was missing. I read a bug report that advised to remove and reinstall
the gluster package in order to properly recreate the file. Since that did
not work, I created it manually.

Thank you,

Joel

Re: [ovirt-users] ansible and list of vms

[Nathanaël Blanchet]

Le 10/05/2017 à 10:29, Ondra Machacek a écrit :

Not sure I understand. You can use Ansible module to list VMs, you
can use ovirt_vms _facts[1] module.

For example to get only stopped VMs, you can use following:

- name: Get stopped VMs
  ovirt_vms_facts:
auth:
  url: https://ovirt.example.com/ovirt-engine/api
  username: admin@internal
  password: password
  ca_file: /etc/pki/ovirt-engine/ca.pem
pattern: "status = down"
I want a list of vms sorted by any possible attributes, i.e. sorted by 
datacenter or cluster, not only by status.


 * For example, ovirt_vms_facts doesn't allow to get the datacenter the
   vm belongs to , and the pattern filter doesn't return a list of vms
   as expected:


- hosts: localhost
  connection: local
  tasks:
  - name: Get stopped VMs
ovirt_vms_facts:
  auth:
url: https://acore.v100.abes.fr/ovirt-engine/api
username: admin@internal
password: ovirt123
insecure: true
pattern: name=centos* and cluster=west
  - debug:
  var: ovirt_vms
  - shell: echo "{{ ovirt_vms.name }}"

How can I successfully display this list of vms like described here :
namedescription returnedtypesample
ovirt_vms 	List of dictionaries describing the VMs. VM attribues are 
mapped to dictionary keys, all VMs attributes can be found at following 
url: https://ovirt.example.com/ovirt-engine/api/model#types/vm. 	On 
success. 	list 	



 * About the python SDK:

list_vms.py could be what I expect, but vm.datacenter_name doesn't exist

Re: [ovirt-users] do we need some documentation mainteiners?

[Fabrice Bacchella]

I'm might be saying things in a harsh way, but there is a real big problem with 
public documentation at ovirt, especially the latest python sdk.

I'm coding a python wrapper around the sdk4 and fighting a lot with 
documentation. 

First I tried to google:
ovirt python sdk4
ovirt python sdk 4
ovirt rest api 4

I was finally given http://ovirt.github.io/ovirt-engine-sdk/master, but 
http://ovirt.github.io returns a 404, the sdk is hidden under 
http://ovirt.github.io/ovirt-engine-sdk/, a mini-site that is barely usable, as 
it very hard to navigate between page. For example, when you're at : 
http://ovirt.github.io/ovirt-engine-sdk/master/version.m.html, how do you go to 
the first page ?

If I try to gogle the title of this page, I found 
http://www.ovirt.org/develop/release-management/features/infra/python-sdk/ as 
first result and it's even not in the first page of results .

Or you can have a look at 
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html-single/python_sdk_guide/,
 that talks only about v3 sdk, which is deprecated.

The python sdk change log:
http://www.ovirt.org/develop/sdk/python-sdk-changelog/

At pypi, no links to the sdk documentation
https://pypi.python.org/pypi/ovirt-engine-sdk-python

I requested the events codes, I was given that:
https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/AuditLogType.java#L726

Is there a formal list somewhere ?
