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!

moving storage away from a single point of failure
by Robert Story 25 Sep '15

--Sig_/d8.0dmwks3vvUk8CoFxP3Dz Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hi, I'm running oVirt 3.5 in our lab, and currently I'm using NFS to a single server. I'd like to move away from having a single point of failure. Watching the mailing list, all the issues with gluster getting out of sync and replica issues has me nervous about gluster, plus I just have 2 machines with lots of drive bays for storage. I've been reading about GFS2 and DRBD, and wanted opinions on if either is a good/bad idea, or to see if there are other alternatives. My oVirt setup is currently 5 nodes and about 25 VMs, might double in size eventually, but probably won't get much bigger than that.

VNC console behind NAT
by Alan Murrell 25 Sep '15

25 Sep '15

Hello, I am able to connect to SPICE that is behind a NAT (via Squid), but am wondering if there is a way to do it with VNC as the console option? I thought I had this working at one point, several installs ago, but it doesn't seem to be the case currently. When I do try to connect to a VM configured to use VNC as the console option, the remote-viewer screen opens, says "Connecting to graphic server", then after about 30 seconds or so says it is unable to connect to the graphic server. Thanks! :-) Regards, Alan

HI While mounting the EXport Domain to the different engine getting below error, Error while executing action New NFS Storage Domain: Error in creating a Storage Domain. The selected storage path is not empty (probably contains another Storage Domain). Either remove the existing Storage Domain from this path, or change the Storage path). -Nagaraju

HA - Fencing not working when host with engine gets shutdown
by Michael Hölzl 25 Sep '15

25 Sep '15

Hi all, we are trying to setup an ovirt environment with two hosts, both connected to a ISCSI storage device, a hosted engine and power management configured over ILO. So far it seems to work fine in our testing setup and starting/stopping VMs works smoothly with proper scheduling between those hosts. So we wanted to test HA for the VMs now and started to manually shutdown a host while there are still VMs running on that machine (to simulate power failure or a kernel panic). The expected outcome was that all machines were HA is enabled, are booted again. This works if the machine with the failure does not have the engine running. If the machine with the hosted engine VM gets shutdown, the host gets in the "Not Responsive state" and all VMs end up in an unkown state. However, the engine itself starts correctly on the second host and it seems like it tries to fence the other host (as expected) - Events which we get in the open virtualization manager: 1. Host hosted_engine_2 is non responsive 2. Host hosted_engine_1 from cluster Default was chosen as a proxy to execute Status command on Host hosted_engine_2. 3. Host hosted_engine_2 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" 4. Host hosted_engine_2 is not responding. It will stay in Connecting state for a grace period of 124 seconds and after that an attempt to fence the host will be issued. Event 4 is continuously coming every 3 minutes. Complete engine.log file during engine boot up: http://pastebin.com/D6xS3Wfy So the host detects the machine is not responding and wants to fence it. But although the host has power management configured over ILO, the engine thinks that it is not. As a result the second host does not get fenced and VMs are not migrated to the running machine. In the log files there are also a lot of time out exception. But I guess that this is because the host cannot connect to the other machine. Did anybody face similar problems with HA? Or any clue what the problem might be? Thanks, Michael ---- ovirt version: 3.5.4 Hosted engine VM OS: Cent OS 6.5 Host Machines OS: Cent OS 7 P.S. We also have to note that we had problems with the command fence_ipmilan at the beginning. We were receiving the message "Unable to obtain correct plug status or plug is not available," whenever the command fence_ipmilan was called. However, the command fence_ilo4 worked. So we use a simple script for fence_ipmilan now that calls fence_ilo4 and passes the arguments.

Older hardware deployment
by Chas Ecomm 25 Sep '15

This is a multipart message in MIME format. ------=_NextPart_000_00D6_01D0F555.6C3D0CF0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit I've searched on this issue all over the place and not found a full answer. I've got a lab with older Dell PE860 servers with Pentium D processors. We are attempting to prove out that we can move from VMware to KVM and oVirt, but with 3.5 we can't get these servers to enter into a cluster due to the age of the processors. I've seen it referenced in a few list entries to modify 'the database' to put CPUInfo entries in for the processor capabilities of this processor, but it is unclear to me and I've been unable to find any documentation that speaks to what database and how to modify it safely. I know we could update these servers and get better power consumption, heat generation, etc., but it's not in the cards and I can't move my newer servers until we prove it out with these older ones, which ran ESXi 5.5 with absolutely no issue. This cluster will be a functional test and small tools cluster ultimately, so I don't really care about their lower end specs, either. Would installing something older than 3.5 help me here? Or is there some doc somewhere I've just not found that describes this process of updating the DB with these CPU parameters.
