[Users] A mobile monitoring application for oVirt
by Martin Betak 03 Feb '15

03 Feb '15

Hello oVirt users, I'm in the process of developing a simple monitoring application for oVirt on the Android platform. This is still under heavy development, but first usable version can be found at [1] Please note that this is still a development preview so it can be a little unstable and the UI design is not yet perfect (well ... design by programmer :-)) but I hope it could be useful. All comments, remarks, feature requests and general feedback are very welcome. You can file any issues directly at [2]. Below follow the details of using and configuring the app. Description: The goal of this project was to create a simple Android app that would enable oVirt admins to configure conditions on Vms, Clusters, or whole datacenter upon which they want to be notified. At the moment you can configure 3 types of "Triggers": - when Vm CPU is over given level - when Vm Memory usage is over given level - when Vm enters given state (Down, Unknown ...) You can also choose if you want just simple standard android notification or also want the device to vibrate. You can also define all these triggers on per-Vm, per-Cluster or "global" level. Configuration: On first run the app will prompt you to enter connection parameters of your running oVirt engine instance. API URL should be in the form of http://host:port/ovirt-engine/api Username is user@domain i.e. admin@internal Password is ... well the above user's password :-) sadly only http (not https) is supported so far for endpoint url. If you have any more questions feel free to use this thread and I'll do my best to answer them :-) Best regards, Martin [1] https://github.com/matobet/moVirt/blob/master/moVirt/moVirt.apk [2] https://github.com/matobet/moVirt/issues

[Users] connecting to oVirt/RHEV VMs through proxy and the oVirt API
by i iordanov 31 Oct '14

31 Oct '14

Hello, My apologies for cross-posting, but this discussion concerns both mailing lists, I think. In Opaque, I recently started setting the proxy property of SpiceSession from a console file, as is done in remote-viewer, in order to support installations where the nodes are not "visible" from the point of view of the client. However, then I remembered that I have not seen the proxy property being available through the oVirt/RHEV API. I looked at the latest remote-viewer code, and I looked through the oVirt/RHEV API documentation, and indeed, I see no way to get proxy information other than through the console.vv file. If I am correct, then this means that both Opaque and remote-viewer cannot connect to VMs behind a proxy unless a console.vv file is used, which also means that since console.vv files are unobtainable through the User Portal on mobile devices, mobile devices effectively cannot at all connect to such VMs if the user is not an Administrator. Would it be possible to expose the proxy parameter through the API? I couldn't find a bug opened about this, but it doesn't mean it isn't there :). Thanks! iordan -- The conscious mind has only one thread of execution.

[Users] How to See Ovirt Console From a Remote Windows Host
by Jon Forrest 13 Oct '14

13 Oct '14

I know that this is simple for some of you, but I also know from Googling around that lots of people have had trouble seeing their ovirt console from a remote Windows host. Below I describe what finally worked for me. I hope this helps somebody avoid wasting as much time as I did today. I'm a fairly experienced VMWare user who's learning ovirt. I just installed an all-in-one ovirt server and copied a CentOS 6.5 iso into it. I then tried to boot a new VM but soon learned that console access is different in ovirt than on VMWare. I then spent over an hour trying the various documented ways to view a remote console using Spice on my Windows 7 desktop. I even tried using a Linux VM to see if the Firefox plugin for Spice would work. Nothing. What finally worked was installing the virt-viewer Windows client (http://virt-manager.org/download/) Then, I opened the ovirt Administration Portal in Firefox running on my Windows 7 desktop. I created a new VM and configured it the way I wanted. Then, from the "Virtual Machines" tab, I started the new VM. Pretty soon the little console icon turned green so I clicked on it. I got the prompt from Firefox asking me what app I wanted to associate with the ".vv" URL that opened when I clicked on the console icon. I browsed around and selected \Program Files\VirtViewer\bin\remote-viewer.exe which is from the virt-viewer client package I installed above. I told Firefox to always use this app for this kind of file. This works great! I was able to boot the CentOS system and install it with no problems. Good luck! Jon Forrest

[Users] Unable to delete a snapshot
by Nicolas Ecarnot 23 May '14

Hi, With our oVirt 3.3, I created a snapshot 3 weeks ago on a VM I've properly shutdown. It ran so far. Today, after having shut it down properly, I'm trying to delete the snapshot and I get an error : "Failed to delete snapshot 'blahblahbla' for VM 'myVM'." The disk is thin provisionned, accessed via virtIO, nothing special. The log below comes from the manager. I hope someone could help us because this server is quite serious.

"Could not connect host to Data Center" after rebooting, how to resolve?

Hi list, I had to do some fsck-related things last week on my ovirt box (centos, single node and NFS on localhost). Afterwards ovirt refused to start VMs according to the webinterface because it can't connect host to Data Center. On my OS it works fine (I just replaced the IP by 'IP'): [root@server ovirt-engine]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_leiden-lv_root 51606140 6872592 42112108 15% / tmpfs 3978120 0 3978120 0% /dev/shm /dev/sdb1 495844 99542 370702 22% /boot /dev/mapper/vg_server-lv_home 62990260 2584272 57206196 5% /home /dev/sda1 5814366992 4629615452 1184751540 80% /raid IP:/raid/ovirt/data 5814367232 4629615616 1184751616 80% /rhev/data-center/mnt/IP:_raid_ovirt_data IP:/raid/ovirt/iso 5814367232 4629615616 1184751616 80% /rhev/data-center/mnt/IP:_raid_ovirt_iso in my event log in the webinterface I found correlation ID 7a735111 .

How should I solve this? To me everything looks just fine. Cheers Boudewijn Ector
