Foreman: Add external provider (Failed with error PROVIDER_FAILURE and code 5050)
by Daniel Helgenberger 25 Sep '15

25 Sep '15

Hello, did anyone actually get this working in oVirt 3.5 / EL6 - Engine? I am trying this for two days now. Setup: Engine; EL6.5 Foreman; EL6.5 Foreman seems to do it's as I can use it to deploy hosts and also smart proxies are running fine. I have opened a BZ [1]; because this really can not work out of the box with EL6 plain vanilla packages. I wonder if this was ever tested... ? Java 7 used i n EL6 [4] does only support DH keys up to 1024byte. This is known issue in Foreman [2] as longer DH keys are now used by default in Foreman / PuppetCA. A dirty fix confirmed working is adding default DH parameters to the foreman cert; effectively disabling it [3]. So I got SSL working and I get beyond the authentication (entering wrong data gets me auth errors)- however, I am still not able to add the external provider. Pressing 'test' results in (Failed with error PROVIDER_FAILURE and code 5050) Sample engine.log 2014-10-28 23:49:40,860 ERROR [org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand] (ajp--127.0.0.1-8702-1) [6a3da4e7] Command org.ovirt.engine.core.bll.provider.TestProviderConnectivityCommand throw Vdc Bll exception. With error message VdcBLLException: PROVIDER_FAILURE (Failed with error PROVIDER_FAILURE and code 5050) I can't find any more hints in oVirt; access logs in Foreman are telling me API queries by the engine. Did I miss a crucial step in the foreman setup? How can I debug this issue? I am willing to upgrade openjdk; provided this does not break my engine... Thanks!

Multiple NICs on hosted engine?
by Chris Adams 06 Jun '15

06 Jun '15

I have installed the first node of a new oVirt 3.5 setup with a hosted engine VM. I have multiple networks: one public-accessible and one private (with storage, iDRAC/IPMI, etc.). I set the engine VM up on the public LAN, but now realize that it can't access the power control. I tried to add a second NIC to the engine VM through the web interface, but of course that doesn't work (because it isn't really managed there). How can I add a second NIC to the hosted engine VM? -- Chris Adams <cma(a)cmadams.net>

Deploying oVirt engine has never been so easy. Checkout oVirt dockerized projects on docker hub[1] and github[2]. You can find some overview on oVirt-dockerized blog[3] Please let me know if you find it useful. Cheers, Moran.

[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

name of virtual machine and hostname
by nicola gentile 28 Jan '15

28 Jan '15

Good morning, I would like to ask you an information. After I have installed ovirt, I have created a pool of vm with name like centos-?? (from 1 to 20) and then ovirt generated 20 vm with name centos-1, centos-2, centos-3 etc. etc. The problem is when the vm starts the hostname is not the same of the vm name in ovirt but is the same name of the template. Is it possible to make sure that the name of vm and the hostname is identical? Best regard Nicola Gentile
