Undeploy oVirt Metrics Store
by toslavik＠yandex.ru 23 Apr '19

23 Apr '19

Deployed MetricStore on the engine and hosts as per the instructions. But using some time I realized that for me the functionality is redundant, enough data collected by DWH. https://www.ovirt.org/develop/release-management/features/metrics/metrics-s… Is there an instruction on how undeploy oVirt MetricStore?

Hi, I think you can go to the disk section in UI and migrate the disk from 1 storage domain to another. Best Regards, Strahil Nikolov

oVirt nVidia vGPU driver questions
by femi adegoke 17 Apr '19

17 Apr '19

I'm on oVirt 4.2.6. 1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver? 2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7? 3) Must the vGPU driver be installed on the host & in the vm? 4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”

How to fix ovn apparent inconsistency?
by Gianluca Cecchi 16 Apr '19

16 Apr '19

Hello, passing from old manual to current OVN in 4.3.1 it seems I have some problems with OVN now. I cannot assign network on OVN to VM (powered on or off doesn't change). When I add//edit a vnic, they are not on the possible choices Environment composed by three hosts and one engine (external on vSphere). The mgmt network during time has been configured on network named ovirtmgmntZ2Z3 On engine it seems there are 2 switches for every defined ovn network (ovn192 and ovn172) Below some output of commands in case any inconsistency has remained and I can purge it. Thanks in advance.

oVirt Node 4.3 Master on fc28
by femi adegoke 12 Apr '19

12 Apr '19

4.3 Master is looking good!! A few questions: - In Step #2: Fqdns: for a 3 host cluster, are we to add the 2nd & 3rd hosts? - In Step #5: Bricks: What effect does the RAID setting have? Enable Dedupe & Compression is new? Configure LV Cache: what do we enter for SSD? What happens if my disks are already all SSD, do I still benefit from using this?

Expand existing gluster storage in ovirt 4.2/4.3
by adrianquintero＠gmail.com 11 Apr '19

11 Apr '19

Hello, I have a 3 node ovirt 4.3 cluster that I've setup and using gluster (Hyperconverged setup) I need to increase the amount of storage and compute so I added a 4th host (server4.example.com) if it is possible to expand the amount of bricks (storage) in the "data" volume? I did some research and from that research the following caught my eye: old post "https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-62…" So the question is, if taking that approach feasible? , is it even possible an oVirt point of view? --------------------------- My gluster volume: --------------------------- Volume Name: data Type: Replicate Volume ID: 003ffea0-b441-43cb-a38f-ccdf6ffb77f8 Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: server1.example1.com:/gluster_bricks/data/data Brick2: server2.example.com:/gluster_bricks/data/data Brick3: server3.example.com:/gluster_bricks/data/data (arbiter) Options Reconfigured: cluster.granular-entry-heal: enable performance.strict-o-direct: on network.ping-timeout: 30 storage.owner-gid: 36 storage.owner-uid: 36 cluster.choose-local: off user.cifs: off features.shard: on cluster.shd-wait-qlength: 10000 cluster.shd-max-threads: 8 cluster.locking-scheme: granular cluster.data-self-heal-algorithm: full cluster.server-quorum-type: server cluster.quorum-type: auto cluster.eager-lock: enable network.remote-dio: enable performance.low-prio-threads: 32 performance.io-cache: off performance.read-ahead: off performance.quick-read: off transport.address-family: inet nfs.disable: on performance.client-io-threads: off Thanks.

Ovirt does not support AMD EPYC CPUs?
by Erick Perez 11 Apr '19

11 Apr '19

Hi, In its current release, OVIRT only shows AMD Opteron G1,G2,G3,G4,G5 and no mention of EPYC. This thread mentioned that a respin of Ovirt will address this, but never happened. https://lists.ovirt.org/archives/list/users@ovirt.org/message/2PEAYGK5PE33W… comments?

Re: Vagrant Plugin
by Jeremy Tourville 10 Apr '19

10 Apr '19

Thanks for your reply Luca, I confirmed the cluster name, it is "Default". I even tried to run the script again and I made sure the D in default was upper case because linux is case sensitive. It still fails in the same way as before.

I was able to get Vagrant installed and could even run the example scenario listed in the blog. https://www.ovirt.org/blog/2017/02/using-oVirt-vagrant.html My real issue is getting a vm generated by the SecGen project https://github.com/SecGen/SecGen to come up. If I use the VirtualBox provider everything works as expected and I can launch the vm with vagrant up. If I try to run using Ovirt provider it fails. I had originally posted this over in Google groups / Vagrant forums and it was suggested to take it to Ovirt. Hopefully, somebody here has some insights. The process fails quickly with the following output. Can anyone give some suggestions on how to fix the issue? I have also included a copy of my vagrantfile below.
