Subject: oVirt UI plugins feature announcements
Hello everyone,
I'd like to share some important updates on oVirt UI plugins feature.
First of all, UI plugins wiki [1] is finally complete. API reference
(application events, API functions, API options, entity types) now
includes all the details and snippets of example code. I've also added
section Why load plugins via iframe element? explaining reasons behind
this design decision.
[1] http://www.ovirt.org/Features/UIPlugins
Great! Thanks a lot for the documentation - this makes life much easier!
You might have noticed the changes in oVirt Engine URI layout [2], these
are already reflected in UI plugins wiki. For existing plugins, this means
changing URLs like this:
/webadmin/webadmin/plugin/ExamplePlugin/start.html
to this:
/ovirt-engine/webadmin/plugin/ExamplePlugin/start.html
[2] http://gerrit.ovirt.org/#/c/20473/
Which version of oVirt uses the new URI - I assume 3.4? (and do you know
if the URI will be changed in RHEV as well)?
Correct, new URI layout takes effect in oVirt 3.4, not sure about RHEV but I
think ovirt-engine in URI might change there.
I think it's important to mention this change in oVirt upgrade/release
notes to let users know that they have to change the UI plugin URI. When
packaging an UI plugin it's not a problem to check the oVirt version in
a %post section and run a sed command over the JSON file...
I assume the URI layout change BZ [https://bugzilla.redhat.com/961677] will
have some release notes attached.
For UI plugins, I was talking with Alon about this, we could promote the use of
relative URIs to make UI plugins unaware of absolute URI layout.
For example, in plugin descriptor:
url: plugin/ExamplePlugin/start.html // relative to WebAdmin base context
path, i.e. /ovirt-engine/webadmin
would result in:
iframe src=plugin/ExamplePlugin/start.html
custom content could be added like this:
api.addMainTab('Example Tab', 'example-tab', 'plugin/ExamplePlugin/tab.html');
and any content within the iframe (either start.html or tab.html) could use:
script src=dir-relative-to-plugin-resources/custom-script.js
link href=dir-relative-to-plugin-resources/custom-stylesheet.css
I'll verify this and update the UI plugins wiki accordingly. Should have
thought about relative URIs in the first place :)
I also have a question (not related to this topic) too:
In webadmin I select e.g. a vm and click on Disks webadmin displays disk
details for this vm. When selecting another vm I can see the disk infos
for this vm (webadmin keeps me in Disks subtab which is what I would
expect).
When I click on Monitoring Details (which is a subtab created by my
monitoring UI plugin) and I select another vm webadmin doesn't show me
the content of the ui plugin subtab (Monitoring Details) but instead the
Disks subtab (always the last clicked non-ui-plugin subtab).
Didn't test in in oVirt 3.3 yet, only in oVirt 3.2 and RHEV 3.2...
Is it possible to let subtabs created by ui pugins behave in the same
way as subtabs provided by webadmin?
Right, this is a known issue with dynamic sub tabs. I've created RFE BZ
[https://bugzilla.redhat.com/1028968] to track this issue.
Thanks for your feedback!
Regards,
René
We're planning to merge patch Improve UI Plugin vs. REST API integration
[http://gerrit.ovirt.org/#/c/20404/] soon, please review the change
outlined in commit message, let me know if you have any questions.
Last but not least, oVirt Space Shooter (a.k.a UI plugins crash course)
wiki [3] has been updated to reflect changes mentioned above.

Re: [Users] oVirt Updates - Special KVM Forum/oVirt edition
On Oct 27, 2013, at 22:31 , Itamar Heim ih...@redhat.com wrote: A great week at linuxcon/cloudopen/kvmforum/ovirt conference at Edinburgh, and some other nice feedback on oVirt, meriting a special edition of this update. There are recordings and slides for *all* the talks in ovirt/kvmforum tracks already, please check out http://www.ovirt.org/KVM_Forum_2013 for slides and youtube session recordings. Cloudopen videos are not yet released, but they should be professionally recorded, so worth a wait:) Thanks, michal Feel free to chime in with your feedback as well. It is sometimes hard to remember we only released oVirt 3.0 last year, and that it takes time to get traction. For example, see slide 3 in the presentation i gave on oVirt Updates[1] to see the clear trend in adoption (via total users mailing list addresses). Similarly, in Livnat's oVirt-intro session at CloudOpen, with ~75 people in the room, almost all raised their hand on her question who knows/has oVirt. We had a plethora of topics (same link as [1]), but i wanted to highlight: SUSE support During Livnat's talk, a question was raised wrt SUSE support. Asking for more details, we got ~I'm running oVirt in testing and RHEV in production. with 200 SUSE 10/11 servers. I just want the guest-agent to have their ip address in the gui. So first of all, good to know SUSE runs as a guest without issues. Also, the guest-agent itself is just a python script that should just work. Just some packaging is required, so we're looking to revamp this in build.opensuse.org, and hope some SUSE users will help us with closing and testing this one. In related SUSE news, I just saw this posted After looking into oVirt it looks absolutely fantastic. Might look into seeing if I can help with porting this to openSUSE. What kind of work is involved in the porting of the application like this? (discussion ongoing) on PPC: Leonardo from the Eldorado research center in Brazil gave a lecture on their work to add PPC support to oVirt. Paul Mackerras (KVM PPC developer) from IBM and Alexenader Graf attended and gave a lot of feedback, and potential interest from other PPC vendors, which should be hopefully mostly config level changes. User Stories: Keele university presented their path to oVirt. Always nice to hear how our project is used, and we actually asked them a lot of questions on why/how they use it the way they do. They also did a case study with Dave Neary, which i hope to see more from oVirt community members. Also, always nice to hear: in an irc chat on #ovirt: I looked at ovirt about 4 months ago and when I came back a few days ago I was blown away at how far it had come! The devs have done an awesome job. All KVM Forum/oVirt sessions slides (and youtube's) should be available here[1] Thanks, Itamar [1] oVirt Updates session by Itamar Heim http://www.youtube.com/channel/UCRCSQmAOh7yzgheq-emy1xA ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Live storage migration snapshot removal (fails)
I can open a bug on this. Should I file it for the entire snapshot removal fails-problem or just this error? I've looked at the parsing error and the problem seems to be that the qemuImg.check() function expects a qemu-img version that outputs a string like: Image end offset: 262144. The only version I could find that does that is the one in the F19 virt-preview repository. Stock F19 qemu-img doesn't have this output. Nor do the stock EL6 or qemu-img-rhev EL6 versions. The only function that calls qemuImg.check is blockVolume.shrinkToOptimalSize() this function needs (and uses) the parsed offset to shrink the LV containing the qcow2 image.

Subject: oVirt UI plugins feature announcements
Hello everyone,
I'd like to share some important updates on oVirt UI plugins feature.
First of all, UI plugins wiki [1] is finally complete. API reference
(application events, API functions, API options, entity types) now
includes all the details and snippets of example code. I've also added
section Why load plugins via iframe element? explaining reasons behind
this design decision.
[1] http://www.ovirt.org/Features/UIPlugins
Great! Thanks a lot for the documentation - this makes life much easier!
You might have noticed the changes in oVirt Engine URI layout [2], these
are already reflected in UI plugins wiki. For existing plugins, this means
changing URLs like this:
/webadmin/webadmin/plugin/ExamplePlugin/start.html
to this:
/ovirt-engine/webadmin/plugin/ExamplePlugin/start.html
[2] http://gerrit.ovirt.org/#/c/20473/
Which version of oVirt uses the new URI - I assume 3.4? (and do you know
if the URI will be changed in RHEV as well)?
Correct, new URI layout takes effect in oVirt 3.4, not sure about RHEV but I
think ovirt-engine in URI might change there.
Ok, thanks for the information!
I think it's important to mention this change in oVirt upgrade/release
notes to let users know that they have to change the UI plugin URI. When
packaging an UI plugin it's not a problem to check the oVirt version in
a %post section and run a sed command over the JSON file...
I assume the URI layout change BZ [https://bugzilla.redhat.com/961677] will
have some release notes attached.
For UI plugins, I was talking with Alon about this, we could promote the use
of relative URIs to make UI plugins unaware of absolute URI layout.
For example, in plugin descriptor:
url: plugin/ExamplePlugin/start.html // relative to WebAdmin base
context path, i.e. /ovirt-engine/webadmin
would result in:
iframe src=plugin/ExamplePlugin/start.html
custom content could be added like this:
api.addMainTab('Example Tab', 'example-tab',
'plugin/ExamplePlugin/tab.html');
and any content within the iframe (either start.html or tab.html) could use:
script src=dir-relative-to-plugin-resources/custom-script.js
link href=dir-relative-to-plugin-resources/custom-stylesheet.css
I'll verify this and update the UI plugins wiki accordingly. Should have
thought about relative URIs in the first place :)
Thanks for the hint of relative URIs!
I also have a question (not related to this topic) too:
In webadmin I select e.g. a vm and click on Disks webadmin displays disk
details for this vm. When selecting another vm I can see the disk infos
for this vm (webadmin keeps me in Disks subtab which is what I would
expect).
When I click on Monitoring Details (which is a subtab created by my
monitoring UI plugin) and I select another vm webadmin doesn't show me
the content of the ui plugin subtab (Monitoring Details) but instead the
Disks subtab (always the last clicked non-ui-plugin subtab).
Didn't test in in oVirt 3.3 yet, only in oVirt 3.2 and RHEV 3.2...
Is it possible to let subtabs created by ui pugins behave in the same
way as subtabs provided by webadmin?
Right, this is a known issue with dynamic sub tabs. I've created RFE BZ
[https://bugzilla.redhat.com/1028968] to track this issue.
Thanks a lot for creating the BZ.
Thanks for your feedback!
Regards,
René
We're planning to merge patch Improve UI Plugin vs. REST API integration
[http://gerrit.ovirt.org/#/c/20404/] soon, please review the change
outlined in commit message, let me know if you have any questions.
Last but not least, oVirt Space Shooter (a.k.a UI plugins crash course)
wiki [3] has been updated to reflect changes mentioned above.

Re: [Users] Bug: adding LocalStorage Data Centers
I created a BZ for this: https://bugzilla.redhat.com/show_bug.cgi?id=1029107 additional info: we were able to reproduce this with a fresh ovirt 3.3 setup, without defect storage connections, so this can not be the storage connection bug.

Re: [Users] Bug: adding LocalStorage Data Centers
Hi Sven,
What is the path of the third local storage domain you can't add.
Could it be the same as the other existing connections (/home/DATA,
/data/images/rhev)?
It could be an issue of this bug https://bugzilla.redhat.com/1023739 - -
Cannot create same Local SD path on different Hosts

https://[your-rhevm-setup]/api/storageconnections (!), please
I tried to add another one for host 4, by putting the host into
maintainence mode, and then clicking: setup local storage
When you click then ok in the popup you get the error:
can't add storage connection, connection already exists
So it means that you have a storage connection which is not used by any
storage domain. One thing is how it was created (I suppose a duplicate
of aforementioned bug), the other - how to fix it.
Fix:
* GET https://[your-rhevm-setup]/api/storageconnections
* find id of the problematic connection
* DELETE
https://[your-rhevm-setup]/api/storageconnections/[id_of_the_connection]
Last step perform with cURL or REST Client for Firefox or whatever is
your favourite tool for REST API.
The bugzilla entry seems not to fit as this is:
a) no NFS Storage Domain
Doesn't matter, it may happen for any non-iSCSI (and maybe non-FC)
storage, localfs duplicate here:
https://bugzilla.redhat.com/show_bug.cgi?id=1014966
b) no Export Storage Domain
Doesn't matter, I've seen it for data domains as well.
Here you have duplicate for ISO:
https://bugzilla.redhat.com/show_bug.cgi?id=991739
c) the name of our SD does not contain any spaces
Doesn't matter, the only important thing is if you ever tried to add
this domain and the command failed.
d) the bug entry mentions this bug only occurs via api
because the webfrontend doesn't allow to create SDs with spaces
however how can I check if the postgres db doesn't contain any other
storage domains, just to make 110% sure this is not this bug?
You don't have additional storage domain, you have only additional
storage connection. That's why I asked also for output of
api/storageconnections

[Users] Default route on hosts
Before I ask my question, I want to make sure I'm using the right terms: engine == the system that manages the ovirt environment. Runs the web interface, etc host(s) == the physical machine(s) the engine uses to deploy virtual machines on. Sometimes referenced as a node? vm(s) == the guest systems that are controlled by the engine and run on the hosts, that do the stuff you present to the world at large, whatever your world at large would be. Is that correct? In my environment, I have a customer facing network and another network that's on a set of isolated switches. I desire to use the isolated network as the management network, and am naming the other network public in the web management interface. In the interface, I see these labeled as ovirtmgmt and public, for the management network (private) and the customer facing network (public). From what I can tell from poking at the configuration files, and from a couple references in other threads, the 'DEFROUTE' setting in the ifcfg-* files gets set to 'yes' only for the ovirtmgmt network, not for any other bridged network. I can override this by hand as I deploy hosts, but am hoping for a way to do so within the ovirt management framework, so I have less bits that can go wrong. Is there a way for me to get the DEFROUTE set to no for the ovirtmgmt interface and to yes on the public interface as I deploy hosts? Is there a reason I'm not seeing for avoiding this behavior? --Chris ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Bug: adding LocalStorage Data Centers
Hi Maor,
thanks for this hint. It definitely could be some kind of an issue of
that bug.
Iirc we had this error in our logs but I also tried to change the path -
same results.
I'm also curious about the fact that the first two host have this same
path and they work.
If I delete one of those I can add another one but the deleted host
can't be readded until I delete another one (no matter what node you
select).
btw:
Our storage connection output was ok - one connection per domain - no
orphan connections.
Fabian Deutsch already assumed that it might have been a bug with a non
deleted storage connection. Sadly that wasn't the reason.
The sc output posted by Sven was from a later stage of this project
where we already had experimented with several export domains. The
local storage bug occured before that with a fresh installation of
oVrit 3.3.
Regards
Daniel
PS: I work with Sven on the same project.
