(i.e - java on top of android, Swift/Objective-C on top of IOS) 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. (?) 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 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?

I also have a gluster storage cluster. There are 4 storage domains, an Export domain (Export-Dom1) nfs v1, and ISO domain (Gluster-ISOs) posix FS v1, a Data domain (Gluster Data) GlusterFS V3, and a Data (Master) (Gluster-VM-Store) GlusterFS v3.

Thanks Sven, Detaching the domain is not an option, sorry if did not make it clear i meant to backup the storage domain while VMs are running. Also regarding the Live Snapshot option, The live snapshot simply create a second hardisk for the VM and start to write on it.. it does not do any backup just a restore point. Thanks, Mohye.

Yes exactly, so you can safely backup the first disk. You have a consistent point in time backup. But it depends on your workload, if you run dbs inside the vm you want to have an agent for backups in the vms. there is plenty of documentation on this topic available. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH Co.

[ovirt-users] Upgrade order 3.4.2 - 3.5.x
Hi, maybe a stupid one. Just want to make sure that nothing goes wrong. We plan to make a rolling upgrade of our landscape going to 3.5.1 in december. So we always need some hypervisor nodes up and running during the process. Looking at older posts I assume that upgrading the engine should be sufficient, while hypervisor nodes with vdsm 4.14.17 (from 3.4 repos) and the active VMs keep on running. The start of the engine after the upgrade should catch up and resync all states. Afterwards I clean hypervisor hosts one by one and clean/reinstall it into the cluster? Thanks in advance.

[ovirt-users] How to do Simulation of huge ovirt setup
Hi All, I am writing a solution to monitor ovirt/RHEV manager which will list out all the entities and thier properties/statistics. My setup consists of manager running on virtual machines and 2 physical machines acting as hosts. However I am interested in creating a setup where I will have hundreds of hosts and thousands of vms. I have looked at following tutorials. http://www.ovirt.org/VDSM_Fake http://www.ovirt.org/Vdsm_Developers#Fake_KVM_Support However I faced problems such as manager not recognizing hosts/setting their status to Install Failed/Non-responsive. Is there a detailed step-by step guide available to do the fake/simulated PSR setup. I have availability of VMs but not of physical hardware. Please let me know if this is correct forum or should I ask on the devel list.___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] webhook
Hi,
if I get this correctly, you'd like to be notified when certain event
happens (VM created/deleted/etc.) and react upon that. I see multiple
possible approaches here:
0, improve Engine extension API (refer to Alon Bar-Lev for details)
- if extensions can be packaged as JARs and these JARs could include
web fragments [1] it would mean the possibility to deploy custom
servlets onto existing Engine instance (in context of webapp that
processes extensions)
- your custom Java servlet could query REST interface (or be notified
once something happens, but AFAIK we don't have that implemented yet)
and do whatever logic is needed
- once I asked Alon about ^^ but never got response from him
- IMHO this would be a nice way to deploy custom Java code on Engine
[1] https://blogs.oracle.com/swchan/entry/servlet_3_0_web_fragment
1, improve UI plugin API
- add VirtualMachineDataLoaded event fired upon each refresh of
VM data in UI table (generalization - {Entity}DataLoaded)
- this is similar to existing {Entity}SelectionChange events
2, write UI plugin that uses oVirtJS to periodically check VM events
The disadvantage of 1, and 2, is that WebAdmin GUI must be open.
In any case, if you'd like to explore the possibility of doing this
via UI plugin, I'm here to help.

Subject: Re: [ovirt-users] webhook
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!

Hi all,
Just a quick question. Is it possible to set a webhook on the removal and
creation of a new vm? So we can send to foreman a delete action when the
VM
is deleted...

(i.e - java on top of android, Swift/Objective-C on top of IOS) 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. (?) 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 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.) Sorry, I was very excited about the news, so I forgot to answer the rest. I agree about user portal - sounds good to begin with. Another idea I had in the past is to have an app (push-based) that will push events to a special client. We will have a push sever that will get notifications from the event notifier, and this server will push the events to registered clients. Excellent idea! Could we get such notifications and publish them to some event bus within Engine backend (exposing them to other webapps running within Engine EAR context) + have WebSocket webapp that pushes them to connected clients? (or, if we don't want WebSocket, some other push-like alternative) Imagine a different way to build JavaScript web applications - it first fetches all relevant data, caches it, and then just receives updates that modify its cache. 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 do you mean is that possible? technically sounds feasible to me (well, we'll need to figure out about the console, but an mgmt app without the console, why not?) ) What would people like to see in such an app?

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. The custom script is currently the only option to add files via Cloud-Init Thanks, Shahar Havivi. 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). 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, 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! Hi, Please if somebody can help me because I am pretty stuck. As I said in previous posts I used this Python example http://www.ovirt.org/Features/Cloud-Init_Integration to set root password, hostname and resolv.conf. It worked without any problems for 3.4 oVirt version and equivalent Python SDK (ovirt-engine-sdk-python-3.4.x.noarch). Then, I have tried to write through yuml scripts more conf files than just resolv.conf to configure guest. I also saw this post on the list: http://lists.ovirt.org/pipermail/users/2014-October/028539.html. So based on that, I decided to upgraded oVirt and SDK (ovirt-engine-sdk-python-3.5.0.7-1.el6.noarch) to 3.5 version. The upgrade itself passed without any problem. From that point forward I tried to use custom_script parameter (as suggested by Shahar) inside Initialization class and CloudInit class without any luck. Can somebody please provide a simple Python code to submit yaml script to cloud-init? Also after the upgrade the example script I mentioned above can only change hostname. It does not write resolv.conf anymore nor it sets root password. I don't know if something is changed inside methods? For example, customization of virtual machine (memory,cpu,high availability, pinning to a certain host etc works
[ovirt-users] templates and freeipa
Ovirt 3.5 is running well for me and I have freeIPA controlling access to the user portal. I would like to provide templates of various linux setups that all have freeipa for user authentication in the VM for my developers to be able to create a new VM from and then log in using their freeIPA access and sudo control. I'm wanting to group developers by project and use freeIPA to set sudo commands as needed (group A get oracle, group B get postgresql, etc). Wanting to maximize developer ability while minimizing my clean up time :-) They will be able to delete VMs they create. It's possible to do a kickstart deploy with freeIPA registration but a template from that will be a problem as it will have the same keys for all VMs. Is there a post-creation scripting process I can attach to in ovirt or should I look at a default root user and script that personalizes the new VM? -- -- James P.

I have 1000 VMs in my setup, and I just added a VM named z, it will
be added to the last page which is not displayed right now, so I
wouldn't even be aware that something was added.
(2) potentially creating fake events:
changes in the displayed data in the UI can occur due to change in the
Search query; if I have 50 VMs in my setup, and I initially had the
Vms: search query, and now I change it to VMs: name = a*, which
results in displaying only 10 VMs, this may falsely hint on removal
of 40 VMs from the system.
2, write UI plugin that uses oVirtJS to periodically check VM events
not sure if this is referring to VM-related events in the code (e.g.
hooking to the click on OK within the New VM / Remove VM dialog,
or hooking to the Success callback of the action response, or
something similar), or to the VM-related Events (i.e. the ones that
are displayed in the GUI within the Events main-tab / bottom section).
If the former: can be done, I assume, though not sure how complex it
would be to implement the infrastructure for that.
If the latter: this will catch actions that were performed either
via the GUI or outside the GUI; in this case, it would probably be
better to use an Engine extension API (solution 0 above) rather
than a UI plugin, since it will be more reliable, will be active
even when the GUI is not in use, etc.
The disadvantage of 1, and 2, is that WebAdmin GUI must be open.
In any case, if you'd like to explore the possibility of doing this
via UI plugin, I'm here to help.

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!

Oved

Hi all,
Just a quick question. Is it possible to set a webhook on the removal
and
creation of a new vm? So we can send to foreman a delete action when
the
VM
is deleted...
Kind regards,
Koen

Re: [ovirt-users] How to do Simulation of huge ovirt setup
Hi This is the correct forum, and you according to the problem description you should use VDSM_Fake. Your problem is that when you install a host from API, it tries to connect via SSL and install the agent. You need to update your VDC_OPTION table. 1. Shut down the ovirt process 2. Run psql on your postgres machine and run the following command: update vdc_options set option_value='false' where option_name='InstallVds'; update vdc_options set option_value='false' where option_name='EncryptHostCommunication'; You should be able to connect to the hosts now.

Hi,
if I get this correctly, you'd like to be notified when certain event
happens (VM created/deleted/etc.) and react upon that. I see multiple
possible approaches here:
0, improve Engine extension API (refer to Alon Bar-Lev for details)
- if extensions can be packaged as JARs and these JARs could include
web fragments [1] it would mean the possibility to deploy custom
servlets onto existing Engine instance (in context of webapp that
processes extensions)
- your custom Java servlet could query REST interface (or be notified
once something happens, but AFAIK we don't have that implemented yet)
and do whatever logic is needed
- once I asked Alon about ^^ but never got response from him
- IMHO this would be a nice way to deploy custom Java code on Engine
Please allow me to step in as someone who worked on the extensions API as well,
There are more missing bits here.
You are referring to the webapp side, but this is not enough.
We have also the engine side which has to become more pluggable.
In addition, we will probably need to handle all kinds of issues that rise from
our singletons at engine - class loading might be an issue here, no?
You don't want the X-ton (doubleton, tripleton, etc..) phenomena in your
setup - you don't want for example X instances of AsyncTaskManager.
I think that in general we should strive to turn engine into way more
pluggable/modular than it is now, imagine an engine microkernel (for those of
you who did not hear the term microkernel, I am referring you to jboss
architecture) - we should have a thin microkernel and the rest of the code
should be pluggable, using the extension API (and perhaps web fragments as
well).
What do you think?
[1] https://blogs.oracle.com/swchan/entry/servlet_3_0_web_fragment
1, improve UI plugin API
- add VirtualMachineDataLoaded event fired upon each refresh of
VM data in UI table (generalization - {Entity}DataLoaded)
- this is similar to existing {Entity}SelectionChange events
relying on changes in the UI table is a bad idea:
(1) potentially missing events:
the UI displays paginated data; if my VMs are sorted by name, and
I have 1000 VMs in my setup, and I just added a VM named z, it will
be added to the last page which is not displayed right now, so I
wouldn't even be aware that something was added.
(2) potentially creating fake events:
changes in the displayed data in the UI can occur due to change in the
Search query; if I have 50 VMs in my setup, and I initially had the
Vms: search query, and now I change it to VMs: name = a*, which
results in displaying only 10 VMs, this may falsely hint on removal
of 40 VMs from the system.

I used an example given here: http://www.ovirt.org/Features/Cloud-Init_Integration . But unfortunately I cannot do the same thing If I want to write multiple files to a vm in params.Action class. Thank you in advance! 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: http://cloudinit.readthedocs.org/en/latest/topics/examples.html#writing-out-arbitrary-files Shahar Havivi. 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. The custom script is currently the only option to add files via Cloud-Init Thanks, Shahar Havivi. 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 http://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). 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, 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! Hi, Please if somebody can help me because I am pretty stuck. As I said in previous posts I used this Python example
