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

Adding custom network filter to oVirt
by Peter 01 Aug '18

I can see from the libvirt docs how to create a new network filter (to block STP broadcasts in my case), but how do I add that filter to the vNIC list in oVirt?

I think we are in a race to see who can get a new HCI setup built faster. There have been a few hurtles along the way :) On Tue, Jul 31, 2018, 6:53 AM Bill Dossett, <bill.dossett(a)pb.com> wrote: > Hmm, resounding silence….

Migrating Legacy Hyperconverged Legacy switch type to OVS
by Mike 01 Aug '18

01 Aug '18

Spent the better part of a day trying to figure out how to bridge OVN networks with physical networks, only to later find out that "Attach to physical network" has zero effect in a Legacy cluster... which started me down the rabbit hole of "how do I switch the Default cluster to be OVS" Then, I come up with the bright idea that I'm going to create a new OVS cluster and migrate all the hosts there, well in order to do that you might: 1. Put the Host into maintenance 2. Install to UNDEPLOY the hosted engine 3. Remove the host from the cluster 4. Add the host to the new OVS cluster However this has a nasty bug where the required networks won't ever sync I believe because of some QoS settings (even though I haven't set that), so host is not able to reach gluster storage, and this was not one of the 3 replicas, it was just a client So moving on just to test the waters with another angle, I UNDEPLOY on one of the gluster servers, and then and only then after waiting however long it took to install/undeploy, does it tell me that It can't remove this host from the cluster because it holds gluster volumes......... How in the heck can I migrate what I have on Default to use native OVS? Let's say I started fresh (I'm using oVirt Node 4.2.5) since I have that option....I don't ever recall there being an option to select OVS as the hosted-engine switch type, and it of course sets up the Default cluster for you - which is the one I'm having issues with because it's legacy by default. Thanks
