upgrading 4.0.1 to latest 4.2
by Charles Kozler 15 Aug '18

15 Aug '18

Hello - I am kicking around different ideas of how I could achieve this I have been bitten, hard, with in place upgrades before so I am not really wanting to do this unless its a complete last resort...and even then I'm iffy Really, the only configuration I have is 1 VDSM hook and about 20 networks. The physical hardware is not going anywhere. Out of my three nodes, I can push all VM's to the other 2 nodes and do a fresh build on 1 node I am hoping there may be a way for me to do a fresh install of 4.2, export engine config from 4.0.1, and then import it in some way - is this possible? Quick google doesnt yield much and searches for 'export' usually result in storage related results

[ovirt-engine-api-model] Any solutions to add custom key/value pairs into entities?
by Joey Ma 14 Aug '18

14 Aug '18

Hi all, In my case, I need to add customized KVs into API model entities, such as VM, Disk, Template and etc. I looked through the API model documents and got some existing Tag/Property/CustomProperty structs, all of which have limitations and can not work it out. Are there any solutions? Thanks, Joey

Is there a way to specify which volume is used for VM imports?
by Jayme 14 Aug '18

14 Aug '18

I have multiple data volumes and when I import a VM from an NFS attached export domain the disk always gets created on on specific volume. I understand I can move the disk from one volume to another after the fact but is there a way I can specify which volume to use for the initial import?

Network requirements for ovirtmgmt
by Marcel Hanke 14 Aug '18

14 Aug '18

Hi, we currently have a big layer 2 network in our datacenters, so every node in a cluster can reach the other nodes in the datacenter on network layer 2. In the future we'd like to route directly on the switches and connect the nodes in one cluster, as well es other clusters in one datacenter via network layer 3. The question now is, do we need multicast and/or broadcast for any operation, or is the connectivity with layer 3 fine? Thanks Marcel

Connection issues when using gluster + infiniband + RDMA
by housemouse＠squeakz.net 13 Aug '18

13 Aug '18

I am trying to setup gluster using Infiniband and mounting it in RDMA mode. I have created a network hook so that it configures the interfaces as MTU=65520 and CONNECTED_MODE=yes. I have a second server doing NFS with RDMA over Infiniband with some VMs on it. When I try and transfer files to the gluster storage it is taking a while and I am seeing the message “VDSM {hostname} command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues” This is usually followed by “Host {hostname} is not responding. It will stay in Connecting state for a grace period of 60 seconds and after that an attempt to fence the host will be issued.” I just installed the Infiniband hardware. The switch is a Qlogic 12200-18 with QLE7340 single port Infiniband cards in each of the 3 servers. The error message varies on which of the 3 nodes it comes from. Each of the 3 servers is running the opensm service.

Passing through Quadro cards to guest
by Wesley Stewart 13 Aug '18

13 Aug '18

Has anyone experimented with this? I have had really good success with AMD cards, but consumer end graphics cards fail to load due to NVIDIA blocking them. I happened to have an NVIDIA Quadro P2000 lying around and I thought I would give it a shot. I really like these cards as they only require the 75W provided PCI power. I can pass the Quadro through just fine, however after a couple minutes of playing a video, the audio gets really "buzzy" and the video drops to about 3-5 FPS. This is while doing pretty minimal stuff. Currently testing with 720/1080 youtube videos. Card is pulling about 6-10W total. And otherwise working fine on my Windows 10 guest. I have also tried enabling/disabling MSI interrupts which the card supports without making a difference. I am running a single host setup: X10SDV-6c+ (Xeon D - 1528) running oVirt 4.2.3
