[Users] VM payload
Hi, I created a vdsm hook script for passing payload information (vm name) to a virtual machine, which is placed in before_vm_start folder on my hypervisor (CentOS 6.5). If I create a new virtual machine out of a template some strange things happen: When starting the vm the first time I can see that the vdsm script is executed, but no additional cd drive is shown in this vm. But after shutting down the vm and powering on again, the cd drive appears. Here's the vdsm hook I use: https://raw.github.com/ovido/ovirt-stuff/master/hooks/50_payload I don't really get why the payload isn't working when starting a vm the first time. This happen on oVirt 3.2 and 3.3.

In Nagios this is done in the check scripts / on the client side while Zabbix mainly collects data and fires triggers if certain conditions in that data are met. Yes that's true. Maybe adding a Zabbix compatibility mode for check_rhev3 could also be an option where no decisions about the status is done in the script so you can let Zabbix triggers handle this?

I specifically need the scsi support (virtio-scsi). I do know about the virtio-block support, which results in /dev/vd* devices as you say. From what I read even EL6 earlier than 6.3 does not support virtio-scsi Sorry, I did read your email to fast as it seems. You're right you need at least RHEL 6.3 for virtio-scsi support.

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)

Re: [Users] ovirt nagios plugin email flood on engine upgrade
On Sun, 2013-10-27 at 10:08 +0200, Itamar Heim wrote:
Hi René,
a question - when we upgrade the engine, we move the service to down.
at that point, nagios is sending lots of emails on each failing
monitored resource due to inability to connect to the API.
Hi Itamar,
That's the default behavior of Nagios - it send's out an email for all
services which aren't in state ok.
As check_rhev3 plugin uses the API for all datacenter, cluster, storage,
host, pool (and maybe vm) checks and during upgrade the API isn't
available all service checks fail and so Nagios starts spamming.
Is thee a way to report this once per the root cause for all monitored
resources?
Yes, there are multiple ways how you can prevent mail floods.
First of all I suggest to schedule downtimes in Nagios for all affected
hosts/services. If a service has a scheduled downtime no notifications
will be sent out during this time (no matter how often state changes).
If using Icinga CGI gui or Icinga-Web instead of Nagios you can select
multiple hosts and choose Schedule Downtime For Checked Host(s) and All
Services. I'm not sure if this is implemented in Nagios CGI gui as well
or if you have to do this step for all hosts manually.
An alternative to downtimes is disabling notification globally. But keep
in mind that you want receive any notifications during this period - so
e.g. a firewall outage isn't reported via email then either.
Beside the handling of planed downtimes there's also a feature I
recommend you to prevent email floods if the engine goes down unplanned:
service dependencies
(http://nagios.sourceforge.net/docs/3_0/dependencies.html)
All my check_rhev3 service checks are members of service group rhev
and I created a service dependency where no notifications are sent out
(execution_failure_criteria n) if a service of service group rhev is in
a state other then ok and the datacenter check oVirt DC Status Check
on host ovirt-engine.lab.ovido.at is in state unknown, critical or
pending:
define servicedependency {
host_name ovirt-engine.lab.ovido.at
service_description oVirt DC Status Check
dependent_servicegroup_name rhev
execution_failure_criteria n
notification_failure_criteria u,c,p
}
With service dependencies for all check_rhev3 checks you will only
receive 2 notifications when engine is down: 1 for the first service
check failing and 1 for the DC Status Check (this checks is triggered
automatically when using service dependencies and one of the services
fails).
Please let me know if you need further information (service dependencies
can be quite confusing)...
Regards,
René
Thanks,
Itamar

Your feedback and input is invited. I think your proposal looks way better than the current oVirt interface and I think it would definitively be an improvement. Though I think the oVirt admin interface still looks somewhat bloated. I always thought that it shows too much information at once, but only few of these facts are actually useful. Some columns are useless most of the time. This is especially true if you consider the Virtual Machines tab just an overview, not an in-depth view of all VMs. Lets discuss this further: - Display: not interesting if I just want to see the overview - Status: redundant, the icon in the first row already tells me about this - Uptime: not interesting at all, I never used this information for anything - Host, IP, Cluster, Datacenter: Really, why should I care about these details, if I just want to see an overview of my VMs? If I want to know any of these, I can click on any VM and see every detail. Or I choose a specific datacenter or Cluster to see specific details about it. I think this applies to almost every overview page in oVirt. It's too much information at once, and even worse, too much useless information. The point is to show only *really* important information first (status, usage), and from this point the user/admin should be able to go deeper and view specific details. Remember, it's just my opinion :-) as malini mentioned, this focused on look and feel. please open a BZ to track the RFE of allowing to choose which columns to see per main tab. I'm of the same opinion as Frank (and others) - there should be an option to remove/add columns to improve the look and feel. Focusing on look and feel includes this discussion as well (imho) - not just colors. The login screen posted by Malini looks really great - much better then the actual one. I also like the colors of the webadmin interface, but usability is decreased (in the screenshot) compared with the old design. Let me explain why: When I click on Virtual Machines the most important information for me is the name of a virtual machine, but it's not that easy to find the name (Name column is smaller as Host, IP Address, Cluster and Data Center). If the Name would be bold (or in another color) and columns can be removed it's much easier for me to find the right vm. Furthermore the columns for Memory, CPU and Network are ways to big and the green is too bright - this is just additional information which can be very useful but shouldn't attract me too much. So I suggest to highlight the vm names in some way and make the Name column the bigger then all other (per default - users can resize it anyways). The blue highlight of the tabs looks nice, but I fear many users will not recognize these items as tabs. As a conclusion: I like the new colors a lot, but a few adjustments are needed to improve the usability.

Your hypervisor must be CentOS 6 or Fedora 18/19 in order to be able to manage it with oVirt (other Linux distributions are still a wip).

E.g. Limit CPU, Memory and Network for group of test vms, but give full resources to production vms. Maybe this could be done with cgroups? So e.g. I don't want to give a compile machine a full cpu core, but only 1 core with 500MHz or limit the bandwith to e.g. 10Mbit/s. Hi René, Due to time constraints, it did not make it into the 3.3 release, however in master we already have network QoS allowing you to limit bandwidth for vNICs. Also, we managed to implement CPU shares which allows you to handle priorities. Both will be included in the next version, and hopefuly some more. So if you ever feel like taking a ride with the bleeding edge, you have both network QoS and CPU shares waiting there. Thanks a lot for the information! It's great to know that this is/will be available. - Upload ISOs within the GUI to ISO domain - Use existing share for ISO domain When creating an ISO domain, oVirt creates it's own directory structure with IDs. It would be nice if an existing share could be used (e.g. an ISO share on NFS server which is used by other service, too) without creating the structure with IDs. I know that the IDs are needed internally but I think

Thanks, Itamar [1] from the top 12 V Allow disk resize Great!

Great to hear that spice support has improved and Chrome can be used as well! Other items mentioned in previous survey which should be covered by now: - Fix timeout when adding local host during all-in-one configuration - Fix engine set-up when SELinux is disabled - Provide packages for el6 (CentOS, Red Hat Enterprise Linux) - Allow multiple VMs to be deployed from the same template at the same time - ISO domains on local/GlusterS ISO and export domains on FC/iSCSI would be good to have as well. - Show IP addresses in Virtual Machines-Network Interfaces - OpenStack Quantum support (now called Neutron) - noVNC support - Support spice.html5 and websocket proxy - Add other guest OSes to list Good to hear that other Linux distributions will be added as well. - Port oVirt guest agent to Ubuntu[6] - SLA - Allow resource time-sharing - Spice - Mac client (via mime based launch) - Spice - port XPI plug-in to Windows (not sure this will happen, but mime based launch allows using firefox now) - Spice - client for Ubuntu/Debian (should be covered via mime based launch) Additional features I would like to see are: - oVirt guest agent for Ubuntu/openSUSE/SLES/Debian * *Ubuntu is already available thanks to Zhou Zheng Sheng - Resource pools At the moment only Quotas are available (which is great, btw), but in some cases it's necessary to implement resource pools. E.g. Limit CPU, Memory and Network for group of test vms, but give full resources to production vms. Maybe this could be done with cgroups? So e.g. I don't want to give a compile machine a full cpu core, but only 1 core with 500MHz or limit the bandwith to e.g. 10Mbit/s. - Upload ISOs within the GUI to ISO domain - Use existing share for ISO domain When creating an ISO domain, oVirt creates it's own directory structure with IDs. It would be nice if an existing share could be used (e.g. an ISO share on NFS server which is used by other service, too) without creating the structure with IDs. I know that the IDs are needed internally but I think it should be possible to reuse an existing share. Last but not least I want to thank all contributors of this project for their great work so far! Regards, René [2] hosted engine is in active development, but not released yet. [3] host update is supported, but not for general yum update.

Re: [Users] Setup Host Network dialog - actions availability [ux][BZ#984737]
On Thu, 2013-08-22 at 13:04 -0400, Einav Cohen wrote: Hi, This is about attempting to address the difficulty of finding the edit-action in the Setup Host Network dialog, as documented in Bug 984737 - usability: webadmin difficulty in assigning client ip, no gateway possible in bugzilla. We have a suggestion from Eldan (see attached HostSetupNetworks-HoverPopUp.png) which was described in the BZ (comment #3) and seemed acceptable by the reporter (comment #4), however IIUC - one of the main pain points described in the BZ was the fact that the user could not find the option to Edit the connection properties since he was looking in the wrong place, and needed to hover on the correct place, in order to find that option. So although the idea is somewhat helpful, my concern is that this solution is not enough (comment #5). Another proposal from Malini (comment #6) is to add an actions drop-down menu in the form of a small gear icon-button - see attached HostSetupNetworks-DropDownMenu.png. This proposal addresses my concern, however I have a question about another concern with this solution: would the actions-drop-down menu-items panel be revealed appear upon click or upon hover? In my opinion this is the better solution but still not enough. Let me explain why: There are 4 reasons (or did I forgot one?) why I want to change the network configuration: 1. Add new logical networks 2. Remove logical networks 3. Change ip addresses of 1 (or more) logical networks 4. Configure/change bonding options Ad 1 and 2: In the Setup hosts networks dialog the behavior is ok - improvements should be done when creating new logical networks. I think neutron integration will improve this... Ad 3: When changing (or adding) an ip address I first have to verify what's the current ip configuration of this host. If I don't use dns/static hosts entry I can see the current ip address of ovirtmgmt host in hosts tab, but for all other networks or when having hostnames configured I have to go to the Network Interfaces subtab of each host. In this tab I can already see the address I (properly) want to change or the interface where I want to add a new ip address. So why not allowing to edit ip addresses here? I don't mean going back to oVirt 3.0 style but just make existing ip addresses changeable here already by making the existing ip address clickable and open the edit network window. Bondings/logical networks should stay in setup host networks and there should also be a gear icon to edit/remove logical networks like in the DropDownMenu.png screenshot which reveals when clicking on it. Then you have the possibility to change the ip config wherever it's easier for you. I also vote for removing the tooltip on logical networks and instead display the ip address (and maybe MTU) below the logical network name. e.g. ovirtmgmt (VLAN 1) IP: 192.168.0.1 - logical network 1 - logical network 2 As ip addresses will most likely be configured only for ovirtmgmt, display network and storage network this dialog wouldn't get floated with too many information... Ad 4: Add a gear icon in the same way as for 3, but keep the ability to change the configuration only in Setup hosts networks dialog, no need imho in Network Interfaces subtab... Regards, René if it will be upon hover, it might seem weird/be conflicted/be somewhat confusing with the hover functionality that reveals the logical-network details pop-up. if it will be upon click, it means that in order to edit a logical network, two clicks will be required in order to get to the edit dialog, as opposed to one click in the current state and in Eldan's suggestion. maybe having two clicks in order to get to the edit dialog is acceptable, however there may be some solutions for that: one possible solution would be to combine both attached suggestions, i.e. the actions within the hover pop-up, as well as the actions drop-down menu, however it means that there will be some redundancy of the actions availability. another possible solution is to keep only the gear + down-arrow icon (or maybe only the down-arrow icon), without the actual drop-down menu there, just in order to indicate that there are some options available in that area, and have Eldan's pop-up appear when hovering on that icon (or even on the entire logical-network area, as happens today with the current details pop-up) thoughts?

Taking all the feedback into account, we have made an iteration to the concept and want to present it back to you for your feedback. Please see attached. In this version, the dialog presents the following flow from top to bottom - 1. enable power management 2. Then Select which cards to use 3. Then indicate to the system whether those cards should be used concurrently or sequentially. Great that you choose this flow - I think it's the one which is the most user friendly one. Within Step 2 in the flow, the details for each card are collapsed by default but can easily be expanded. Besides feedback on the attached mockup, we also have some questions that we would like some clarifications on - 1. When power management is enabled on a host, will atleast one card NEED to be enabled? If yes, is that always the Primary card ( in other words, should the primary card ever be disabled?) I think the primary card has to be enabled whenever power management is enabled, but power management should stay disabled per default. 2. Currently, in the mockup, we have checkboxes to enable and disable certain cards and also the ability to add cards. Should there be an ability to remove cards too in addition to turning them on/ off or is it ok to just add/ remove and take out the checkboxes all together? If you keep with the concept of having a primary and secondary card you shouldn't be able to remove one of these 2 cards - only enabled/disable/edit it. One thing that keeps in mind for a future improvement (somewhere after 3.3) would be a power management template. When having a bigger setup (assuming 20 hosts from the same manufacturer and therefor with the same remote management cards) you have to set address, username, password, type, (maybe port) and (maybe options) 20 times (with 2 cards 40 times). But it would be much easier if I create a power management template and set all parameters except address, choose this template in power management tab of each host and set the address of the card there. But as said - would be nice to have in the future.

It went in recently so may not be in whichever version you're running, but you can probably borrow some of the concepts to get the job done. Thanks a lot for your answer - this definitely points me into the right way. Great, happy to help. Just a few ideas: - create a vm payload [2] and attach it to the VM which can hold your config info e.g. vm name, which a custom script could pick up. No need for the latest oVirt with this option. For some strange reason I totally missed the vm payload feature (and it seems to be introduced already in oVirt 3.1 according to the release notes). Can I attach a vm payload via webadmin portal of oVirt 3.2 (and if yes - how?) or only via REST-API? So if I understand this right, I would do the following: - use before_vm_start_hook which creates the payload and updates vm xml definition - add payloads with e.g. file name unattended.txt andcontent hostname=pool-vm95 - have script started in host which mounts the floppy, reads the content of unattended.txt and do some magic Only REST API.

[Users] Please test check_rhev3 1.3 alpha
Hi, As discussed in previous thread I improved the authentication of my Nagios plugin to use auth cookies per default and fall back to username and password authentication on failure. Here's a documentation how authentication is handled now: https://github.com/ovido/check_rhev3/issues/1 You can download the alpha version from: https://github.com/ovido/check_rhev3/blob/master/plugin-dir/check_rhev3.pl Please note that this is an early development version not intended to use in production setups yet (requires some testing). If you test it, please give me some feedback if the authentication is working as expected. This means, that no user@domain logged in messages appear in oVirt engine (if using oVirt = 3.1) when Nagios is checking oVirt environment. Thanks a lot for testing and your feedback! There's one known issue - if REST-API returns an error the plugin also falls back to username and password. This happens e.g. when querying interface statistics for vlan tagged interfaces on RHEV 3.2, which returns Operation Failed (see https://bugzilla.redhat.com/show_bug.cgi?id=993123). Don't have a solution for this right now... Regards, René ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

The basic idea is to have, first of all, a domain (in our case it´s MS Active Directory) where all of your customers are stored so that they are able to just use their regular accounts when ordering and administering their resources, and a mail-server that can send the confirmations out directly to them. Then it´s our job as admins to fix up some templates so that it´s possible to spin up new VM's fast and effortlessly enough. Another one of the things that enables this solution is to have dynamic DNS activated on the network where these VM's are located so that they can just be called something, e.g. based on their MAC address, like we do. That way, you are able to anticipate what their domain name is going to be. You then register an alias for that domain name with the alias name of whatever the customer wanted it to be called. Create a domain user that you use to connect all of these VM´s to the domain when the template machines start up, so that your customers can log in to their VM's with their regular domain accounts. And create a role in oVirt that you assign to this manager that is only permitted to do what it´s supposed to be doing, and nothing else; create VM, take snapshot, assign permissions, etc. What´s needed to get up and running with all of this? - A LOT!:S Thing is, I´ve done this so that it basically just works for us™, and not much done about making the code dynamic or flexible so you´re going to have to dig in and mod all of the config files so that it fits your situation accordingly. But I thought that since the basic grunt work is done, I might as well share it so that if anyone else gets the same idea, they won´t have to invent the entire wheel all over again, they´ll just have to make my wheel fit into their car:) Anyone who decides they´d like a shot at this, I´ll be more than happy helping with any questions you might have. Big thanks to you developers, who gave me directions about how to use the PythonSDK! I´d also like to give my warmest thanks to the guys at paperboardinc, especially Ning, who helped fixing up the authentication popup. Having an orderportal without an authentication would have been waaay to naive for anyone to stomach:) Screenshots are attached. -- Med Vänliga Hälsningar --- Karli Sjöberg Swedish University of Agricultural Sciences Box 7079 (Visiting Address Kronåsvägen 8) S-750 07 Uppsala, Sweden Phone: +46-(0)18-67 15 66 karli.sjob...@slu.se ___ 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

Finally - I had previously asked about using MD RAID1 redundancy on the root drive, which isn't available yet on the node. Are there any options for creating redundant local storage using MD RAID1, or it's the same -- no redundancy on local storage unless you're using a RAID card where the driver for that card has been integrated into the node? MD-Raid or DRBD,... isn't possible, (yet?). You could try GlusterFS 3.4 (replicated volume over your 2 nodes)... Hope this helps.

Re: [Users] Engine-config -s small problem
Hi, No, oVirt isn't aware of config changes - it's by design, not a bug. You always have to restart engine when changing values (as noted in engine-config help text). # engine-config -h snip ### 2. In order for your change(s) to take effect, ###restart the oVirt engine service (using: 'service ovirt-engine restart'). Regards, René On Fri, 2013-05-17 at 13:57 +0200, noc wrote: Hi All, Don't know if this is documented somewhere but I ran into an interesting problem yesterday. First we had intermittent problems with ssh connecting to VMs which we traced to having two oVirt installation being active in one subnet. Found the post from January where it is explained how engine allocates its mac address pool and how to set it with engine-config -s MacPoolRanges. Today I remembered that I had done that when I was about to start a VM and removed the nic from the VM and added it back. To my surprise it got the same macaddress as it had (from the old range). On a hunch I restarted ovirt-engine and redid the remove/add operation and now it got a new mac address from the range specified. Shouldn't the engine be aware that the config is changed if you use engine-config and reload its cached values from the database? I expected this but it seems not to be the case, bug or by design.

The disadvantage is the inability to connect VMs through the ovirtmgmt network, which requires configuring at least one VM network on any of the hosts in order to be able to configure nics on the VMs. Thanks a lot. I never tried this before. As there are repeating questions about networking I'll try to find some time this week to write a networking documentation (bonding, vlan tagging, non-vm networks,...) in oVirt wiki this week. - create a new datacenter (without hosts in it!) With the fix for https://bugzilla.redhat.com/909820 (merged), any network can be editing, in spite of it's configured on hosts. It will result with network being marked as 'not synced' on the host. - edit ovirtmgmt logical network (if it's not possible: delete it and create new interface ovirtmgmt with vlan tag) - put host(s) in new datacenter - configure network from oVirt webadmin gui (maybe you have to uncheck verify connectivity between engine and hosts) I can't say for sure if the steps above will work - maybe you have to do more directly on the host. Did a few setups with tagged ovirtmgmt interfaces in oVirt and RHEV but newer wrote down a definitive guide for it :( Regards, René -Original message- From:Juan Pablo Lorier jplor...@gmail.com Sent: Wednesday 8th May 2013 21:14 To: René Koch r.k...@ovido.at Cc: users@ovirt.org Subject: Re: [Users] Vlan interface on top of bonding Hi René, Tanks for your help. I've tried in the direction you pointed and I was able to share the bond among other tagged networks. One of the problems would be how to edit ovirtmgmt network now that it's created, I just can't find in the way to do it by the web. I've tried starting a hole new datacenter, but it creates the network and disables all changes. Thus, I can't mark the ovirtmgmt network as tagged and add other tagged networks to the bond. I can't tag the management network neither not use it, so I'm kind of stuck again. Regards, On 08/05/13 11:51, René Koch (ovido) wrote: Hi, first of all welcome to the oVirt project.

If you're using vlan tagging on (bonded) interfaces in oVirt you have to add a vlan tag to all logical networks - can't mix tagged and untagged logical networks. e.g (same for bonds as well): Name - VLAN- Network Name eth0 - eth0.10 - ovirtmgmt eth0.11 - lan1 eth0.12 - lan2 Hope this helps. ___ 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
[Users] NFS domain and LVM
Hi,
I just rebooted my NFS server which hosts a ISO domain which is used by
RHEV 3.1 and oVirt 3.2. In both environments the ISO domain became
inactive and I tried to activate it again.
In RHEV this worked fine, but in oVirt it didn't.
Just for your information: both - RHEV and oVirt use Local on host as
datacenter storage type.
I normally use a local NFS server and mount the share locally (dc with
storage type NFS) as Local on host is making troubles in most of my
setups (in both - oVirt and RHEV) and the issues are mainly missing
(sometimes lost) volume groups.
As my oVirt 3.2 setup is a testing environment and my test vms are still
running, I'll keep it in this state for finding a solution for this. As
said, have seen issues like this more then one time before, so maybe
this is a bug and need some attention (can also open a bug report if
needed).
vdsm.log is telling me that the storage domain doesn't exist (as
complained by vdsm daemon):

Re: [Users] High Availability OVirt
Hi, You can use a cluster software like pacemaker or RH Cluster to make your ovirt-engine high available. I personally recommend to virtualise it on a KVM host, as keeping virtual machines high available is much easier then making all services ovirt-engine need high available (but it's possible for sure). So what happens when your engine hosts goes down: - You can't login into webadmin and user portals - high availability and live migration features of your virtual machines aren't working - You can't start/deploy new virtual machines - Your hosts and virtual machines that are already running stay up of course As clustering brings in more complexity I would use a server with RAID, redundant power supplies and redundant network interfaces (bonding) for ovirt-engine instead of clustering. Only when using desktop virtualization where availabilty of the user portal is really important I would cluster ovirt-engine. (But this is just my personal opinion) Regards, René On Fri, 2013-04-19 at 08:19 -0300, victor nunes wrote: Is there any way to create redundancy oVirt-engine?

Re: [Users] Ipa server inside ovirt itself. ..
Hi, I don't see big issues, as you can always log into oVirt as admin@internal and start/stop/reset/... your IPA-vm. If your other vms use IPA for authentication (e.g. for service SSH) you can configure sssd for caching credentials if your IPA server is unavailable. ipa-client-install is doing it automatically, btw.

Re: [Users] DNS for IPA in oVirt
Hi, Thanks a lot for your detailed explanation. That mean that I don't need DNS entries (forward and reverse) for oVirt engine anymore, only SRV records for the directory service (for sure)? So using IP or /etc/hosts is sufficient.

This will cause the internal java kerberos implementation to issue DNS srv requests per realm (for example, if you want to add the domain example.com, the realm will be EXAMPLE.COM) for kerberos - the srv record query will look like _kerberos._tcp.example.com and it will return a list of KDCs for the realm. If useDnsLookup is not set to true, This will cause the manage-domains utility to issue kerberos DNS srv records, and fill the krb5.conf file with information on KDCs per realm. In return you will get a list of corresponding hosts for the ldap servers. b. If -ldapServers was not passed - a DNS srv record will be issues to get the ldap servers for the domain - _ldap._tcp.example.com after the manage-domains utility performs kerberos authentication. This is done, in order to get a URL of an ldap server to be used, to send an ldap query and get the user id for the given user at the command line utility. So, as long as your DNS is configured properly, and the SRV records are well defined, you will get SRV records for kerberos and ldap. - Original Message - From: René Koch (ovido) r.k...@ovido.at To: ovirt-users users@ovirt.org Sent: Friday, April 5, 2013 3:47:07 PM Subject: [Users] DNS for IPA in oVirt Hi list, I don't want to ask my question in the mail thread of Eduardo to avoid mixing topics.

The second event is at the Graz Linux Days in Austria on April, 20th: http://www.linuxtage.at/ (Sorry, there's no English version available) Details on my presentation (in German): http://glt13-programm.linuxtage.at/events/174.de.html As this event is a non-profit community event I'll be focusing on oVirt, but will also talk about differences to RHEV. Eventually I'll be talking about oVirt on the Linux Weeks in Vienna, Austria, too. This event is from May, 2nd to May, 4th: http://www.linuxwochen.at/ At the moment the call for papers is still running...

Yes, it is an Intel modular server (I don't know well this platform
but I think IMS is its acronym)
You can contact me if you have questions regarding these server - I
use(d) this system in the company I worked before and on customer side.
The multipath working configuration would be more than appreciated ;-)
But does this mean there are configuration with dual scsi or is
multipath needed in every case (as I see oVirt config implies
multipath configuration anyway.)
Attached is a working multipath.conf for RHEV-H 3.0.
You need a working multipath.conf file if you have redundant storage
controllers.
Find out the wwids of your devices and add them to your

Sorry, can't give you detailed information on how to create a Samba 4 directory (use UCS appliance) - there is plenty of documentation in the internet on how to do that. To connect oVirt to your existing Samba domain, use the DNS server from your samba server on your ovirt-engine host (don't do replication to external bind servers, as this causes some issues). You have to make sure, that you have valid forward (A) and reverse (PTR) DNS entries for your ovirt-engine host and SRV records for LDAP, Kerberos,... (but these should be created by default and are required for your Windows clients, too). You can join your Samba4 domain with engine-manage-domains -provider=ActiveDirectory ...

Re: [Users] Templates and originating VM relationship
Hi Gianluca, @oVirt-team: please correct me if I misunderstood something on the template-concept... Unlike Vmware (which converts a vm into a template) RHEV/oVirt is copying the vm into a template. So you can remove or edit your original vm without having an impact on your template. More important is the template provisioning method when creating vms from your template. If you choose Thin, only changes between your template and your vm are written to your vms disk file, where clone creates a clone of your template's disk. Template thin provisioning saves disk space, but you can't delete the template as long as you don't delete all vms linked to this template. The name of your disk is just a name (and it seems that it doesn't have to be unique) - important is the ID, which is used by oVirt internally.

I think it's because of sealing/sysprep. Let's assume you create a template of a windows vm, I would do the following steps: 1. Install all apps and settings in your vm 2. Take a snapshot of this vm 3. sysprep your vm 4. Create a template 5. Revert to previous snapshot when reusing your vm, as otherwise sysprep would start (and you don't want it for your master-image).

Re: [Users] User Portal
Hi, If you login with PowerUser permission you have 2 tabs (Basic and Extended) where Basic is the UserPortal and Extended the PowerUserPortal. So you can switch between these 2 views. Btw, in RHEV (3.0 and 3.1) I see a (for me) strange behaviour and haven't tested if this is the same in oVirt. When installing RHEV a Default datacenter is created and everyone has permission on template blank. As long as I don't remove permissions on blank template user with role UserRole start in PowerUserPortal (Extended view) instead of UserPortal (Basic view) - without permission on template blank they can't switch between these 2 views/portals (which is the expected situation - users with UserPortal permission shouldn't be aware of the PowerUserPortal). Is this bug or intended?

UI framework creates an iframe for each plugin, so the plugin code is separated from the main oVirt webadmin code (and other plugins). When creating a new (big) jQuery dialog in an sub tab-iframe (sub tab of selected vm or host) it can't be displayed without scrolling in the sub tab or resizing the sub tab (that's clear as it's displayed in an too small iframe). So it would be great if it would be possible to display dialogs in the middle of the main windows and overlap the iframe (don't know if this is possible). In short terms I want to create a dialog which behaves like e.g. the Setup Host Networks or Add Permission to User dialogs - click on a link in the plugin iframe and dialog opens in the middle of the website not the middle of the iframe. What I found out so far is that: 1. I must be aware of the same origin policy (that's no problem) 2. I need to put my jQuery-dialog-code in the main oVirt windows and then I can call it from within the iframe (that's my problem) So my questions are: Is it possible to place code outside of the iframe?

[Users] oVirt 3.2 and Solaris 10 guests
Hi, I've a strange network issue with Solaris 10 x86 guests on oVirt 3.2 (beta) with an CentOS 6.3 hypervisor (using dreyou's repository for VDSM packages). My host configuration is the following: Operating system: Other Network interface type: rtl8139 Network Name: ovirtmgmt Disk interface: IDE Disk is working fine and the network interface is detected by Solaris 10 guest, as I can see a rtls0 interface with ifconfig -a and Solaris installer also detects this interface. But when I try to send packages over this interface they never reach a target - e.g. ping the gateway and arp -an doesn't show it's MAC address. On the hypervisor I can see vnet(x) interface is on ovirtmgmt bridge. Network traffic is working fine for all other VMs (RHEL 6 and Fedora 18) on ovirtmgmt bridge. Btw, when creating a Solaris 10 guest on RHEV 3.1 with RHEL 6.3 hypervisor the exactly same issue occurs - network interface is detected but no traffic passes this interface. On a plain KVM-Host (RHEL 6.3) I can create a Solaris 10 host with virt-manager using rtl8139 Virtual Network Interface Device model on a bridge (network setup is nearly the same as for oVirt and RHEV). On this RHEL 6.3 KVM-host network is working fine for Solaris guests. In the process list (ps -ef) the settings for oVirt and RHEL-KVM seem the be nearly the same (different fd's and option bootindex=3 is missing on KVM): oVirt 3.2: -netdev tap,fd=25,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=00:1a:4a:00:64:9e,bus=pci.0,addr=0x3,bootindex=3 RHEL 6.3 KVM: -netdev tap,fd=36,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:8e:3a:57,bus=pci.0,addr=0x3 KVM-Version is exactly the same on CentOS-oVirt-Hypervisor as on RHEL KVM-host: # rpm -qa | grep kvm qemu-kvm-rhev-tools-0.12.1.2-2.295.el6.10.x86_64 qemu-kvm-rhev-0.12.1.2-2.295.el6.10.x86_64 Do you have any clue why Solaris networking isn't working on oVirt but on RHEL-KVM it is? I didn't try Fedora 18 or oVirt Node as a hypervisor yet - don't think that there will be a difference. Thanks a lot for your feedback. -- Best Regards, René Koch ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Try e1000 which is usually much more reliable or virtio iface. I personally always had terrible experience with emulated rtl8139 by qemu-kvm, e1000 was OK. For me, it's the same if I choose the e1000 (which I choose the first time and then try the rtl8139). Same for me - e1000 aren't working with oVirt 3.2 and Solaris 10, too. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] set host status up from backend?
Hi, What happens when you try to activate your host? Is there an error message?
