Can you verify basic IP networking is working correctly for those VMs?
For example, we've established that they can get to the Linux VMs - how?
Are they on the same subnet? Or do they go through their default gateway?
Without knowing the IP topology, if the Linux machines were on the same
subnet as the Windows one, and the Windows machine fail to get to their
default gateway for some reason, this may perfectly explain the issue.

Re: [ovirt-users] Problem with Adding Pre-Configured Domain

[Roger Meier]

Hi Ivan,

The problem is their is no warning in the webUI. I can press the button
and nothing happens (i only see the error message in the logfile) no
error, i stuck in the config UI.

I tried now another approach based on your idea. I turned the master
storage domain into maintenance mode and changed the nfs path and
activated it again with the new share path. After this ovirt used the
slave storage and i can start the VM's of the snapshot and read/write on
it. After the test i switched back with modify the nfs path and started
the VM on the master storage without problem. This works if master 
storage is completly lost and i must switch complete to the slave storage.

The only problem now is for the use case if only one VM had a problem
and I only need the snapshot data which is on the slave storage. I read
your link, and this can perhaps be that what i need, but at the moment
it looks like
a feature that is on status implementation since october last year.
Perhaps it works when i add a new VM on the data storage which create's
empty disk images (or use the existing broken VM) and after that i copy
the disk images from the slave storage over the empty disk images. But
this woul'd be in the console and fault-prone.  An way to import
snaps/replicated storage domains would be realy cool.

Greetings
Roger

Re: [ovirt-users] Error when trying to retrieve cluster, hosts via ovirt API

[Jean-Pierre Ribeauville]

H,

Thanks for infos.

BTW,  as I need to retrieve cluster and datacenter to which my host belongs   
within a software running on the host , I use a Python script 
interacting with the ovirt-engine ; is there another way to get these  infos 
"locally" on the host itself ?

Thx

The certificate is needed to secure the SSL communication. You can do without 
it, adding "insecure=True" to the constructor of the API object, but then the 
identity of the server could be forged and you won't notice.

That should work, but when you are doing this kind of query it is usually 
better to let the server do the search. You can achieve that using the same 
query language that is used in the GUI search bar. For example, in the GUI 
search bar you can type "Hosts: cluster=mycluster".
With the SDK you can do the same, using the "list" method and the "query" 
parameter:

  hosts = api.hosts.list(query="cluster=mycluster")
  for host in hosts:
print(host.get_name())

You can open the "params.py" file
(/usr/lib/python2.7/site-packages/ovirtsdk/xml/params.py if you are using the 
RPM packags) and look for the corrsponding class: Host, Cluster, DataCenter 
etc. There you will see all the available "get_..."
methods.

did you tried  manually running

As far as I know not at the same time.
You have to detach and then attach do the new datacenter.

It's basically for the size, we'll fix it when we'll move to new

This looks strange, the engine should be up at that point.

For 3.6.1 (it should be in 3.6.0 but it's bugged) you will be able to edit
some parameter of the engine VM from the engine (than of course you need to
reboot to make them effective).
I'm not sure if it's worth to make the setup more complex or if it's better
to keep it simple (single nic, single disk) and then let you edit the VM
only from the engine as for other VMs.

You can simply edit the network bindings from the engine:
http://www.ovirt.org/OVirt_Administration_Guide#Editing_Host_Network_Interfaces_and_Assigning_Logical_Networks_to_Hosts

Is up to you to choose if you want just to use the 10 GbE NIC or if you
prefer to create two distinct logical networks or an active-backup bond of
the two interfaces.

Actually after I manually started ovirt-ha-broker and ovirt-ha-agent at
host side, the engine vm has been started.
And I was able to: access it, put infra in maintenanance, shutdown all and
then restart host and exit form maintenance with the engine vm started
again and accessible
I also see italian shown as a possible language, so it is indeed master
version and I can begin to crosscheck... ;-)

To analyze the ERRORS I got from host deploy phase, you can find

[root@ovc71 qemu]# hosted-engine --check-liveliness
Hosted Engine is up!

due to the bug that the storage domain of hosted engine is not shown inside

You can upload the OVA file to export domain with the image-uploader [1].
Then import the template from the domain itself and create a VM with that
template.

[ovirt-users] oVirt Node roadmap

[Fabian Deutsch]

Hey,

in the last few months the Node team spent a lot of efforts in
stabilizing Node by closing tons of bugs, rebasing Node onto CentOS
7.2, and in addition adding features like Hosted-Engine - to get Node
in shape for the recently released oVirt 3.6.0.

But we were also seeing how Node is showing it's age. It becomes more
and more challenging to solve bugs and implement features in Node's
current architecture.
To address these problems, and let Node adjust better to new changes,
a few months ago we started to look at how we can change Node, to make
it easier to develop, test, and use.

This comparison [1] shows a brief summary of our investigations. We
especially looked at Atomic and containers [2].
At the bottom line both of them provided us an architecture which
would help us to achieve something like 70% of what we need. But
during early trials we quickly ran into issues which we experience in
similar ways with today's Node.

Finally we settled an approach - the idea was around since right from
the beginning - which aligns very well with existing technologies
which we already use in the oVirt and Fedora/CentOS scope.

The new Node will be using anaconda for installation, LVM for upgrades
and rollbacks, and Cockpit [3] for administration. The future design
is taking care that packages don't need to take special care to work
on Node - which was a major obstacle in the past. Node will rather
behave (mostly) like a regular host - but with the advantages of an
easy & ready to use image, image based delivery and a robust rollback.
The current design principles and links to some additional resources
are in the wiki [4].

Stay tuned, we are just getting started.

On behalf of the Node Team
fabian

Re: [ovirt-users] Windows Networking Issues -

[Matt Wells]

All networking within oVirt seems fine.  I can ping devices on other
networks, I'm able to use a squid proxy on the same network with no
issues.  I'm able to use Terminal Services from another VM in oVirt.  One
oddity is when I first boot, I'm able to hit Google and search for a Dog.
On my 2nd search it starts to timeout.

All and all ip networking seems to be configured well.  The DG lives
outside of oVirt and I'm always able to ping it; even increasing the packet
size.

MTU size is 1500 and matches the VLAN MTU in oVirt; the bond0 is set to set
to an 9000 MTU.
EM1 and EM2 are in bond0 and show no framing errors.

Hi Willard,

Which packages versions are you using?

Could you provide the output of the following commands:
# yum list installed | grep engine
# yum list installed | grep vdsm

Best Regards,
Roman

Hi Simone,

Looks like the vdsm log is empty...

[root@ovirt-node-01 ~]# ls -l /var/log/vdsm/vdsm.log
-rw-r--r-- 1 vdsm kvm 0 Nov 23 15:41 /var/log/vdsm/vdsm.log

Yes, I did execute the ‘vdsm-tool configure –force’ command before the restart, 
looks like it worked OK, but still the same problem with starting vdsm...

did you tried  manually running 
 vdsm-tool configure --force
before restarting vdsm?

[ovirt-users] Controlling UI table column visibility and position

[Vojtech Szocs]

Dear developers and users,

it's now possible to tweak table column visibility and position
through header context menu in WebAdmin's main & sub tabs [1,2].

  [1] https://gerrit.ovirt.org/#/c/43401/
  [2] https://gerrit.ovirt.org/#/c/47542/

This allows you to turn "unwanted" columns off and re-arrange
those which are visible to match your personal preference.

Screenshot of customizing VM main tab:

  https://imgur.com/5dfh8QA

There's also RFE [3] to persist (remember) such column settings
in the browser, similar to persisting other client-side options.

Vojtech

After uploading the OVA file with image-uploader to the export domain, go
to "Storage" tab, click on the export domain and then click on "Template
Import" tab below, look for your template image and then click on Import.
After this you should be able to see the template under the "Template" tab.

 If you are using 3.6 then you are using ovirt-engine-extension-aaa-jdbc,
 as it is enabled by default, but looks like it isn't related to your
 problem.

 That line takes a long time to execute because it has to process two
 large Python modules: the "params" module that contains a class per each
 type used by the API (393 classes) and the "brokers" module that
 contains a class per each resource used by the API (358 classes). That
 makes a total of 751 classes. In my environment it takes 0.9 seconds,
 approx. You may want to use the python profile in your environment and
 share the results:

 $ cat > profile.py <<.
 import cProfile
 cProfile.run("from ovirtsdk.api import API")
 .

 $ python profile.py

 I won't be surprised to see this taking those 3 seconds in a slower
 environment.

 But even if this takes those 3 seconds it shouldn't be a big problem,
 because you shouldn't be running that "from ... import ..." line
 frequently. Your program should do this once only, when it starts.

You can upload the OVA file to export domain with the image-uploader

The script doesn't contain only the imports, it is also calling the
server, and we know parsing the result is slow, due to the excesive use
of "inspect", as I mentioned before:

  [RFE][performance] - generate large scale list running to slow.
  https://bugzilla.redhat.com/show_bug.cgi?id=1221238#c2

In the profiling information seems to corresponds to the script before
commenting out the part that lists all the VMs, as it looks like the
constructor of the VM class was called 21 times (you probably have 21 VMs):

  21 0.004 1.308

Really useful 
However, I would filter out status columns since this column does not have a 
title and also  I can not see a use-case of removing this column from the view

Thanks Simone for your reply!

You are right: I was bothering you with this setup wishlist item *mainly* 
because further Engine vm modification was impossible/awkward/difficult before 
3.6.1

Nonetheless I have seen many cases in which at least a second NIC would be 
absolutely needed to complete the Engine installation: it is a well known best 
practice to keep the management network (maybe conflated with the IPMI network 
in smaller cases) completely isolated from other services and to allow only 
limited access to/from it, and that network would be the 
ovirtmgmt-bridge-connected network (the only one available to the Engine, as of 
now); now think of a kickstart-based Engine OS installation/update from a local 
repository/mirror which would be reachable on a different network only (further 
access to the User/Administration Web portal could have similar needs but could 
be more easily covered by successive Engine vm modifications)

The "additional disks" part was (maybe "artificially") added by me out of 
fantasy, but I know of at least one enterprise customer that by policy mandates 
separate disks for OS and data (mainly on FC LUNs, to be honest, but FC is 
supported by hosted Engine now, isn't it?)

I absolutely don't know how the setup code is structured (and the recent 
logical "duplication" between mixins.py and vm.conf.in scares me a bit, 
actually ;), but I naively hope that changing the two single hardcoded nic/hdd 
questions into two loops of minimum 1 iteration (with a corresponding 
generalization of related otopi parameters) should not increase the complexity 
too much (and could be an excuse to rationalize/unify it further).

Obviously I could stand instantly corrected by anyone who really knows the 
code, but in exchange I would gain for free some interesting pointers/insights 
into the setup code/structure ;)

[ovirt-users] Strange permissions on Hosted Engine HA Agent log files

[Giuseppe Ragusa]

Hi all,
I'm installing oVirt (3.6) in self-hosted mode, hyperconverged with GlusterFS 
(3.7.6).

I'm using the oVirt snapshot generated the night between the 18th and 19th of 
November, 2015.

The (single, at the moment) host and the Engine are both CentOS 7.1 fully 
up-to-date.

After ovirt-hosted-engine-setup successful completion, I found the following 
(about 3 days after setup completed) "anomalies":

666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/agent.log
666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/agent.log.2015-11-23
666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/broker.log
666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/broker.log.2015-11-23

The listing above comes from a custom security checking script that gives:

"octal permissions" "number of links" "owner" "group" - "absolute pathname"

Is the ominous "666" mark actually intended/necessary? ;-)

Do I need to open a bugzilla notification for this?

Many thanks in advance for your attention.

Regards,
Giuseppe

Re: [ovirt-users] Ovirt 3.6 | After upgrade host can not connect to storage domains | returned by VDSM was: 480

[Sahina Bose]

The error 480 - Gluster volume replica count is not supported, seems to 
indicate that vdsm has not read the updated conf.

Have you made the change in all the nodes (hypervisor)?

Hi Punit,

Based on comment 2 in
https://bugzilla.redhat.com/show_bug.cgi?id=1238093, you should be

and restart vdsm.

Could you attach error that you continue to face (post above step?)

Hi

Seems like you have existing VMs running on the host (you can check that by
looking for qemu processes on your host).
Is that a clean deployment, or was the host used before for running VMs?
Perhaps you already ran the hosted engine setup, and the VM was left there?

CC-ing Sandro who is more familiar in that than me.
