Installation Help
by bilal.ahmed＠kfueit.edu.pk 05 Aug '18

05 Aug '18

Dear Sir I have successfully installed the ovirt engine and ovirt node separately on two machines and I have accessed their web portals as well . But I am facing a problem in its initial configuration that I am unable to add a host and its installation fails . I am using default data center and default cluster . Could you please guide what can be the issue , credentials are correct . I have tried to add both the ovirt engine and ovirt node as a host but failed.

Unable to revive host after a reboot
by Julius Schwartzenberg 03 Aug '18

03 Aug '18

Hi, I recently had to shutdown my oVirt system which contains both the engine and the host. After it came back up, the host was not able to initialize anymore from the oVirt UI. First it kept getting stuck in a loop with setting "ExecutingStarted: Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode." This was being repeated over and over again. It also gave this error: Host pc331 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' Even though I am using that interface (ovirtmgmt) to access the system and 'ip addr show' shows that it's set up properly. I tried some more things, including upgrading the host, When I do that, the status changes to 'Installing' and later to 'Install Failed'. Here are the engine.log, vdsm.log and ovirt-host-deploy*.log: https://drive.google.com/open?id=13vIUDVjPynmAK0pnFRLabDfUlG1lmkpI https://drive.google.com/open?id=10Zm2dDpxM2k5A2bEs_l6gOv_yWv4cjlN https://drive.google.com/open?id=1AieWMzRuA0gZj3x5yDH1AGnsT2E3VtOM Any idea what is going wrong (what I'm doing wrong) and how to solve it? Thanks in advance! Best regards, Julius

How is safe that? I just need do remove the nightly repo and update? Need to apply a yum update * before or not? Please describe me what is the safe procedure. Thanks in advance, Regards, Tibor

Possible to use Console via Mac web browser?
by Jayme 03 Aug '18

03 Aug '18

I recall in the past (on a bit older of an oVirt build) I was able to launch VM consoles from my web browser. I believe it may have been using spice html5 at the time, is this still possible? Currently launching console downloads the typical .vv file. What is currently the best/easiest method to access VM consoles using MacOS?

uploading ISOs
by William Dossett 02 Aug '18

02 Aug '18

Hi, Before I go to the work of making my iso's available to the ovirt-engine so I can use the iso uploader cli. I haven't worked with ovirt for a while and the documents still refer to an ISO domain and engine-iso-uploader the former which I understand is not required now, just wondered if there was any easier way to upload through the web UI maybe? I noticed an upload button under images. could that be used for ISOs? I remember that was something that put me off slightly working with Ovirt last time was the number of steps I had to take to get an ISO available to build a VM from, but if that's still the way I will soldier on. Thanks Bill

Trouble connecting to IDRAC7
by Jayme 01 Aug '18

01 Aug '18

I just enabled power management/fencing successfully on two of my hosts (Dell poweredge R720s with Idrac 7) but am failing to add the third. I enter the IP and user/pass like the others, it takes 15 seconds or so they spits out "Test Failed: Internal JSON-RPC error" I tried resetting the IDRAC on that server. I can also ping it and access it fine in a web browser. I can ping it from the host as well. Is there any configuration in IDRAC that could be blocking the fence attempt or any logs in oVirt I can look at to figure out what might be happening with the connection? I see there is a "fence_idrac" command on the hosts but unsure what switches to use with it to test. Thanks!

Primary passthrough: QXL gets dosent disabled on boot Windows 10
by Alexis Enrrique Gavidia Albornoz 01 Aug '18

01 Aug '18

when the VM boots with the real GPU attached, the emulated QXL graphics gets disabled by windows itself., Moreover, you can install windows 7 running on QXL, then install the real GPU drivers and the QXL will be turned off by windows, why with WIndows 10 dose not ocure the same behaivor, i want to use my Quadro k2200 as the primary board. br Alexis E Gavidia A [cid:3eb0e384-752e-449d-b5d2-dabc1d22cb4f] [cid:f3eecd6f-2333-4d03-9cfc-656de75f4050]

template disk attribute in version 4 restapi
by like.ma＠cs2c.com.cn 01 Aug '18

01 Aug '18

Hi All, In the restapi of version 3, there is bootable attribute in disk. But in version 4, the bootable attribute is removed from disk. For vm i can get bootable attribute from diskattachment. But there is no diskattachment in template. So, is there any way in the restapi of version 4 that i can know if the disk of the template is bootable or not? Thanks Regards. like.ma(a)cs2c.com.cn

Data Recovery from snapshot
by Jim Kusznir 01 Aug '18

01 Aug '18

Hi: With yet another gluster disk failure / gluster collapse, it appears I lost the "main" backing image for one of my vm servers. I have snapshots still in tact (or at least, appear to be), but the main image is gone. The main server process stores a backup at regular intervals in its disk, and that would have been changed data, so it would be in the snapshot rather than the base image. Is there any way to recover this one .tar.gz file from the snapshot with the missing main image? This is a backup of dynamic data, and without it, I will have lost several customers data, some of which cannot be recreated/regenerated. it also appears that my backup (gluster geo-replication) did not work (had crashed a while ago, and has a very old backup of this image). --Jim

[No question] NFS disabled, hosts wandering tearful
by Nicolas Ecarnot 01 Aug '18

01 Aug '18

Hello, This is a simple testimony about what happened yesterday in one of our DC. This DC runs on a dedicated bare-metal engine, oversized compared to the need, thus I've added a NFS service on it to host a small storage domain and the ISO storage domain. Yesterday, after having received the colorful announce about the 4.2.5 version, I decided to upgrade. As our engine was still on a CentOS 7.4, I first upgraded its OS version to 7.5, then reboot. Smooth. Then I followed the very usual oVirt engine upgrade path. Smooth. Eventually, I upgraded the hosts with ovirt-ansible-cluster-upgrade as usual. The result was frightening because the hosts were put in maintenance, upgraded, back to life, seen unavailable, unreachable, connecting, alive, rebooted, then back to another turn and looping... During this, the SPM role was obviously jumping around, and that did not help the debug. In the end, it appeared that something during an upgrade stopped and disabled the NFS service. My hosts partially relied on it, so after having restarted the NFS service, all came back to life. The NFS disabling may come from the CentOS upgrade, except if someone tells me it could come from something on the oVirt side? I'm sure the RH people will advice me not to run NFS on the engine, but apart this event, I had no trouble doing this in years. Regards, -- Nicolas ECARNOT
