There was also project from Iordanov about spice/oVirt support on android..
See:
http://lists.ovirt.org/pipermail/users/2013-December/018434.html

Some days ago it seems he go also support international keyboard layout
support:
"
I finally got some time to back-port the international keyboard layout
support from the Android Ovirt client Opaque into the SPICE client
aSPICE
"

I made same preliminary tests at the end of 2013 but I was not able to
connect to oVirt...
I don't know actually how it went ahead... the Google channel seems stopped
since February...

+100

Sorry for the ignorant question - does this mean the technology will be web 
based or native? (i.e - java on top of android, Swift/Objective-C on top of IOS)

I spoke with mbetak about this a few months ago.
When you speak of console, you mean to actually view the VM using spice? sounds 
very interesting.
If I recall, Alon levy (a former red hatter) worked on some spice 
implementation for html5 or something like that.

Anyway, back in TLV I also had some ideas around that. Do you have some IRC 
meetings or something that I can join?

Cheers,
Yair

[ovirt-users] [RFC] oVirt mobile client

[Greg Sheremeta]

Hi,

The focus of our OPW internship program starting in December will be
mobile and/or lightweight engine clients -- hopefully integrating the
new ovirt.js project.

I see that there are some already existing mobile clients for oVirt.
I'm trying to grasp what we have and what the needs are.

moVirt: https://github.com/matobet/moVirt (mbetak)
This appears to be more of a lightweight webadmin. No console access,
but I believe it's planned as part of OPW. (?)

nomad: http://www.ovirt.org/Project_Proposal_-_Nomad and
https://github.com/Vizuri/ovirt-nomad
Looks dead -- last commit 3 years ago.
Anyone know more about this one?

That's all I see on the first few pages of google.

When I think of a mobile client for oVirt, I think the most useful
part would be the user portal -- simple operations for start, stop,
and the ability to view the console of vms. moVirt mentions it wants
to support some basic management operations, though. I think it would
be difficult to do complex management in a mobile client. (I'm biased
towards huge screens, though.)

I'd like to see an official subproject started that coordinates our
mobile efforts.

Is this possible? What would it take to start it?

What would people like to see in such an app?

Re: [ovirt-users] qemu-kvm from Jenkins - renamed packages to rhev?

[Trey Dockendorf]

Ah, thanks for the info.  I've yet to update to 3.5 but good to know that
the packages are now in ovirt repo for when I do upgrade I don't need to
maintain a copy of qemu-kvm locally.

Thanks,

Well I doubt EL6 support will be dropped from ovirt, as downstream

It won't happen in ovirt-3.6, but support for el6 would be dropped at

I agree that notification sounds like the best option,
Although I would use the SNMP traps for that.
If you already have a SNMP monitoring system you can catch the trap there and 
do your foreman magic.

[ovirt-users] Simple script to split VMs on different host - No affinity group

[Amedeo Salvati]

hello guys,

if you are interested, I wrote a simple python script to balance VMs on
different host/hypervisor, logic is simple and will search for same
couple of vm name and number suffix, odd and even, and it will try to
migrate even VM, if it resides on same host where resides the odd VM.

For example if VMPROJ1PROD01 and VMPROJ1PROD02 resides on same host,
then, the script will migrate only VMPROJ1PROD02.

url of script and rpms are on github:

http://github.com/amedeos/ovirt-BalanceVMOnDifferentHost

and feel free to suggest new patch, enhancement, create a fork...

p.s. I haven't use affinity groups, because maintenance of them will
become a struggle, and I want *only* to run same project/application VMs
with same name on different hypervisor.

Best regards
Amedeo Salvati

[ovirt-users] qemu-kvm from Jenkins - renamed packages to rhev?

[Trey Dockendorf]

In the past in order to have live snapshots work in CentOS 6.5 I had to use
RPMs from http://jenkins.ovirt.org/job/qemu-kvm-rhev_create-rpms_el6/.
I've noticed now that the RPMs have been renamed and no longer match the
names of those distributed by CentOS.  Are the CentOS builds of QEMU now
supporting live snapshots, or are these builds in Jenkins still required?

[ovirt-users] VM Migrate problem on HA Cluster

[N. Vidiadakis]

Hello to all,

I am trying to build a two-node ovirt cluster, using a VNXe 3150 iSCSI SAN.
The two physical machines used for hypervisors are HP DL380p servers, with
128GB RAM and two E5-2630.

On both servers I created a 100GB logical volume used for GlusterFS, to
install on top of it both the hosted engine used and the ISO repository.
Installation was fine, and under Virtualization Manager, the datacenter
seems OK and both hypervisors seems to be registered properly.

I have also added the two hosts to the VNXe, created some iSCSI LUNs to
test the whole platform and created iSCSI bond interfaces to enabled
multipathing.

My problem is that live VM migration only works to one direction, lets say
from server VH1 to VH2, and not backwards. If I try to bring the VM back to
VH1, I get the following:

=
Migration failed due to Error: Fatal error during migration (VM:
Test_Centos_7, Source: hosted_engine_2, Destination: hosted_engine_1).
=

I cant seem (and to be honest dont know exactly how) to identify something
in the log files. I have verified though that both servers are identical,
with the same services up, SELinux disabled, firewalls down and ntp enabled
and reporting same time.

Now, if I powerdown the VM from VH2 and start it up again, it starts OK on
VH1.

Also, if I try to migrate the Hosted Engine itself, I get:

=
Error while executing action:

HostedEngine:

Cannot migrate VM. There are no available HA hosts in the VM's Cluster.
Cannot migrate VM. There is no host that satisfies current scheduling
constraints. See below for details:
The host hosted_engine_2 did not satisfy internal filter HA.
=

and I have already enabled HA Reservation on the Cluster properties.

Thank you in advance,
Nick Vidiadakis

Hello,

I seem to have some issues understating what and when something happens
if I change a cluster or datacenter to a higher version after upgrading
engine.
Maybe somebody could help me understand how this works in general and
when features will get enabled? If possible, pinpoint it to concrete
features added in 3.5.

My assumptions learned form experience so far, upgrading oVirt 3.4 to
3.5; please correct if wrong:
- New features are enabled if I set the cluster compat version to a
newer version after upgrade


unless the features don't need a host change, so engine may just support 
them on your previous cluster level as well.

(or some even at host level upgrade)


- Prior to upgrading a datacenter all cluster need to run the higher
version (seems logical).


yes.


- This involves Engine database updates (?) and, more crucial, it will
change settings and data on the storage domains.


storage domains are only changed on DC upgrade, not cluster upgrade.


- Because of that, downgrade is not possible any more
- Also, its usually safer to keep the old cluster version while using a
newer engine version; because it is more likely to run into regressions
with an upgraded datacenter (see regression blockers for oVirt 3.5.1).

My questions so far:
- What happens if I only upgrade the cluster and *not* yet the datacenter?


you can use new features at host/cluster level (if any), but not DC 
level (storage usually, sometimes network) yet.



- In case of 3.5; exactly when could I have used the new NUMA
management? I assume after upgrading the cluster?


because its unrelated to storage, so its host or cluster level.


- In case of 3.5; exactly when could I have used the new QoS settings
(like disk profiles) - here I assume after upgrading the datacenter?


I think while these are "storage", they only relate to VM behavior, not 
to storage domains, so cluster level sounds like the right level.

doron/allon?



If the the case of NUMA policy is not true but happens only after
upgrading the datacenter, what is the purpose of the cluster compat
version setting? I can think of making sure a certain minimum VDSM
version is running?


simply put:
host level (automatic) - engine may base some features on making sure
host has the right version

cluster level - features which require all hosts to have the new version 
to simplify things (we don't want to not be able to schedule a VM using 
a new feature only on some hosts, so we only allow them after cluster 
level upgrade.


dc level - since storage domains (mostly), and some network definitions, 
span multiple clusters, and for storage, all hosts in the DC may be 
asked to perform the new storage operations, hence DC level makes sure 
all hosts at DC level can do these actions.


and no, I don't have a mapping of which features require which...

Previously, on EL 6.5, Live snapshots worked with oVirt 3.5.

Are Live snapshots on EL 6.6 no longer possible?

Hi Jaicel,
please attach agent.log and broker.log from the host where you trying to
run hosted-engine --vm-status. I have a feeling that you ran into a
known problem on gluster - stalled file descriptor, in that case the
only known solution at this time is to restart the broker & agent as you
have already found out.



Adding Niels and gluster-devel to troubleshoot from Gluster NFS perspective.

actually Foreman has support for puppet, chef and saltstack.
Although it's support may differ in maturity it should be in a usable 
state.

Regarding puppet performance issues... did you read about Puppet Server?

Maybe you should have a talk with the Foreman team over in #theforeman

Date: Tue, 28 Oct 2014 16:52:54 +0100
From: Sven Kieske 
To: de...@ovirt.org 

Hi,

I just wanted to ask if there are some plans to also
support other automation tools like salt, chef, cfengine
or others, because puppet is imho not a good tool for
large environments performance wise.

I noticed there is some support for saltstack in foreman.
So this seems to be a first step to extend the support
for different configuration management tools.

I know RH seems to favor puppet (it's used in the new
satellite product) but I don't think it scales well
(talking about thousands of hosts to manage).

Are there any opinions or plans within the ovirt community
regarding this topic?

This is an interesting feature. I wonder whether something like that should fit 
the cluster/DC, or the provider itself.
As one can create a foreman provider, specifying the relevant location as well.
However, I'm not sure it is really required here, as you have a "search" 
support for provisioned hosts.
So you can easily put a location query there (didn't test it, but see no reason 
for it not to work).
Have you tried that?
We can also add a selection for that in the add host dialog, although the 
dialog is already a bit cumbersome today

Thanks for the input/feedback.

Hi Guys,

restarting ha-broker and ha-agent normalizes the status but eventually

guys could help me with this.



Hi Jaicel,
please attach agent.log and broker.log from the host where you trying to 
run hosted-engine --vm-status. I have a feeling that you ran into a 
known problem on gluster - stalled file descriptor, in that case the 
only known solution at this time is to restart the broker & agent as you 
have already found out.

Jirka


Thanks,

Re: [ovirt-users] webhook

[Oved Ourfali]

Hi 

CC-ing also Vojtech, the "father" of the UI plugins.

Anyway, the only way to accomplish that via UI plugins at the moment is via 
adding a new "action menu item", that in the background deleted the VM, and 
reports to Foreman.
I would be nice to have a "hook" for different UI action items, but it isn't 
available at the moment.
There are plenty code samples for UI plugins, most of them available at: 
http://www.ovirt.org/Features/UIPlugins

I must say that I'm not sure webhooks are the right approach for that, as I 
guess it is relevant only in environments in which one doesn't use the 
API/CLI/SDK
but.. it will be a cool feature!

Regards,
Oved

Hi Shahar,

Thanks! I will try this one. I was not aware of this feature. Although I
can see that it was mentioned on the list (my bad).

Thank you for your effort! I really do appreciate it!

You don't need to use the GUI,
the sdks initialization have custom_script as string which is equivalent to
the text box that you see in the GUI, and you can put the same content there
(ie multiple files).
Is that sufficient enough?

Hi Shahar,

Granted. But the example in python
http://www.ovirt.org/Features/Cloud-Init_Integration uses custom script :)
I just want to know how to do the same thing in case when I want to write
more than one file to a VM - and yes  - all those multiple files that I
want to write are specified via custom scripts.

>From the link - (The "Python SDK" paragraph: scontent object holds the
custom script):

 scontent = "write_files:\n-   content: |\nsearch
example.com\nnameserver 10.10.10.1\nnameserver
10.10.10.2\npath: /etc/resolv.conf"

For example (and just for example), I want to write to /etc/issue and
/etc/hosts not only /etc/resolv.conf. In essence, when vm goes to run-once
mode I want to write more than one file to a vm via Python (using
CloudInit) in automated fashion (and not touching oVirt GUI at all).

Thanks in advance!

The custom script is currently the only option to add files via Cloud-Init

I am using plan vanilla openjdk from the centos repos:

According to

 it might be related.

I am not really sure about the versioning: but the article states this
problem is gone with 1.7.0-21 - yet 1.7.0-65 is installed?




funny, thought only I encountered that issue and fought with it a day
due my out-of-date machine..

I assume foreman integration was not tested against CentOS 6.5 -
engines? Or, might this be foreman in the end? (I am using 1.6.2-stable).


sorry I didn't share (learned for next time) :/ all you need is to
upgrade your jdk, read more about it in the stackoverflow page.

Thanks for raising the issue.

No problem, I am happy to open a BZ - but how do I get the upgrade jdk;
more exactly to which package version? I do not want to break my engine ;)
yum update comes up negative.

I did "yum upgrade java-1.7.0-openjdk" and restarted ovirt-engine service.
the version I currently have is 
java-1.7.0-openjdk-1.7.0.71-2.5.3.0.fc19.x86_64

Hello,

I tried to add foreman as external provider - without successes.

Hosted Engine 3.5
CentOS6.5

The foreman is a plain vanilla install; working so far (can log in, do stuff,
local smart proxy registered)

foreman FQDN is resolvable via DNS

In the engine UI I enter:
https://foreman.lab.mbox.loc
user
pw

and press test.
The cert is shown and after clicking ok, the chain is imported. However, the
test fails with a SSL error. Please see engine log below:

Re: [ovirt-users] Ovirt VM Performance abd CPU times

[Xavier Naveira]

Yeah, that's definitively worth a try. The problem is that we have been
running on ovirt for some months now and haven't realized the problem with
the RHEL 5.x vms until recently, when we began to import them (until now we
mainly run RHEL 6.x vms), so the ovirt hypervisors are production machines
and I don't have a lot of margin doing tests on them. Hopefully next week
we'll be able to decomission another of the "old ones" and then we can do
some testing before adding it to the ovirt cluster... The other thing that
we're going to test is disabling HT.

So one "important" thing is that hypervisor OS was RHEL 5 with plain
Qemu/KVM and instead RHEL 6 with oVirt
You could check if plain Qemu/KVM with RH EL 6.5 generates the same
problems for RHEL 5.x VMs..
Not that it would solve the problem itself, but it would help to put the
different OS version of hypervisor as a possible cause

These hardware is exactly the same, no changes in bios, reinstalled from
scratch.

The versions in the "old ones" are:

RHEL 5.6
kvm-83-224.el5
libvirt-0.8.2-15.el5_6.1
kmod-kvm-83-224.el5

I the ovirt "new" ones:

RHEL 6.5
qemu-img-rhev-0.12.1.2-2.415.el6_5.14.x86_64
qemu-kvm-rhev-0.12.1.2-2.415.el6_5.14.x86_64

I haven't gone into the details but the command line generated by our old

So a point is that the hw is the same and that the problem is only related
to RH EL 5.x VMs.
Also no change in BIOS settings.
Did you reinstall from scratch?

What about the sw?
previously used version of Qemu/KVM and libvirt?
current version of Qemu/KVM and libvirt with oVirt?

Also, did you compare the qemu-kvm generated command line between plain
Qemu/KVM and the one instantiated by oVirt?

Hi Shahar,

Thank you for the reply.

To be honest I knew for those scripts but I want to do it in automate
fashion just like in that example that I put in my original message. I have
tried to specify in params.Files class multiple files:

vm_file1 = params.Files(file=[params.File(name = 'file1', content =
file1_content, type_= 'PLAINTEXT')])
vm_file2 = params.Files(file=[params.File(name = 'file2', content =
file2_content, type_= 'PLAINTEXT')])

and then give them as arguments to params.CloudInit _init_ constructor
(files=...)  just like in that example above but it seems that I am doing
something wrong because it does not write multiple files - it writes only
when you specify one file all right. The exception is "Error: 'list' object
has no attribute 'export'" (I tried to specify those files as a list -
files=[vm_file1,vm_file2]).

Thanks for any help.

Best regards,


Branimir

All:

I just wanted to share the news that oVirt is the hot topic of the week on the 
Red Hat community blog this week!

Moran Goldboim has an excellent two-part article on Dockerizing oVirt[1][2] 
that has so far gotten a good deal of social media and web visit traffic.

Jason Brooks of OSAS has written another installment in his excellent Up and 
Running series, this time focusing on oVirt 3.5! [3]

And I just edited a very detailed article from Martin Sivák on the new 
Optimizer feature in oVirt 3.5. This has not been posted yet, but it could be 
up today or tomorrow, depending on the Community blog's schedule. Keep an eye 
on @oVirt in Twitter for this article's release!

Thank you to Moran, Jason, and Martin for their contributions! If you want to 
write about oVirt, feel free to send me your contributions, and we will get 
them posted!

Peace,
Brian

Re: [ovirt-users] Ovirt VM Performance abd CPU times

[Xavier Naveira]

I haven't tested the performance differences with or without HT. We were
running pure kvm-libvirt hosts on these machines and we're migrating them
to oVirt and that's what triggered the problem with the Redhat 5 vms.

I'll probably give it a try and disable HT on the next hypervisor that
we'll be adding to the cluster next week and see if that solves the problem
or it just mitigates it.

Re: [ovirt-users] Ovirt VM Performance abd CPU times

[Arman Khalatyan]

On our clusters with pure computation we use always HT off, HT was slowing
down scientific calculations.
Just I'm interested if any benefit of enabling HT on the Ovirt host?
At least on my system host-Centos6.5, guest-Centos7VM-LAMPstack with
separate CentOS7-MariaDBVM did not show any performance boost if I switch
on/off HT on 2650v2.

 Hi,

 We are migrating our ifrastructure from kvm+libvirt hypervisors

 ovirt.

 Everything is working fine but we're noticing that all the

 The typical example is an idle machine, running top from the
 machine
 itself it reports cpu use percentages below 10% and loads (with
 2
 processors) of 0.0x. The process running that machine in the
 hypervisor
 rports cpu uses in the order of the 80-100%.

 Should the values look like this? Why are the idle machines
 eating
 up so
 much CPU time?

 Thank you.

Re: [ovirt-users] SPICE HTML5 Browser Clinet does not work

[Frantisek Kobzik]

I exchanged couple of mails with Fumihide and it seems that oVirt doesn't work 
with newest release of SPICE-HTML5 (0.1.5). 

For others: If your setup worked before (with SPICE-HTML5 0.1.4) and stopped 
working after upgrade to 0.1.5 (e.g. from EPEL), downgrading might solve the 
problem.

In the meantime I'll try to investigate what's the problem with 0.1.5.

Cheers,
Franta.

Subject: [ovirt-users] SPICE HTML5 Browser Clinet does not work

Hi everyone,

Today I have updated oVirt 3.5 to GA from RC5.
And I have tried SPICE HTML5 Browser Clinet, but console screen is 'blank'.
Before updating to GA, My oVirt 3.5 could display console screen correctly.
Browser is the Firefox 31 running on Windows 7.

Toggle messages output shows:

[ovirt-users] Hosted-Engine HA problem

[Jaicel R. Sabonsolin]

Hi Guys, 

I need help with my ovirt Hosted-Engine HA setup. I am running on 2 ovirt hosts 
and 2 gluster nodes with replicated volumes. i already have VMs running on my 
hosts and they can migrate normally once i for example power off the host that 
they are running on. the problem is that the engine can't migrate once i switch 
off the host that hosts the engine. 




oVirt 3.4.3-1.el6 
KVM 0.12.1.2 - 2.415.el6_5.10 
LIBVIRT libvirt-0.10.2-29.el6_5.9 
VDSM vdsm-4.14.17-0.el6 




right now, i have this result from hosted-engine --vm-status.

restarting ha-broker and ha-agent normalizes the status but eventually it would 
become "false" and then return to the result above. hope you guys could help me 
with this.

you can use the custom script text box in oVirts cloud-init section,
there you can add any cloud-init section - adding files examples can be found
here:
