As we continue to develop oVirt 4.2 and future releases, the Development and Integration teams at Red Hat would value insights on how you are deploying the oVirt environment. If you haven't already done, please help us to hit the mark by completing this short survey. Survey will close on February 1st. Here's the link to the survey: https://goo.gl/forms/cAKWAR8RD7rGrVhE2 Thanks, -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.

VirtIO-SCSI and viodiskcache custom property
by Matthias Leopold 22 Jan '18

22 Jan '18

Hi, is there a reason why the viodiskcache custom property isn't honored when using VirtIO-SCSI? On a Cinder (Ceph) disk "viodiskcache=writeback" is ignored with VirtIO-SCSI and honored when using VirtIO. On an iSCSI disk "viodiskcache=writeback" is ignored with VirtIO-SCSI and the VM can't be started when using VirtIO with "unsupported configuration: native I/O needs either no disk cache or directsync cache mode, QEMU will fallback to aio=threads" We actually want to use "viodiskcache=writeback" with Cinder (Ceph) disks. oVirt version: 4.1.8 Thanks Matthias

Configuration of FCoE in oVirt 4.2 on HP BladeSystem c7000

------=_Part_3635619_1374417168.1515792280983 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit We are running oVirt 4.2 on a HP BladeSystem c7000 with six BL460 gen 9 blade servers, all running oVirt Node 4.2 distro. We want to configure FCoE for the storage domains, but I find no places in the GUI where I can define the logical network. I guess the documentation on oVirt site (https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks/) is outdated with respect to FCoE. Can anyone tell us how to configure FCoE in oVirt 4.2?

For example, Xeon have 2 threads per core, should I set in oVirt 1 or 2 threads per virtual CPU? IO Threads on or off? On. Any idea of NUMA settings ? Indeed. + Huge pages, in both host and guest. Node running 4 VMs total, CPU load is quite low, RAM is enough to preallocate for each VM + 4GB for node itself. In short, use high performance VM. See ovirt.org feature page. Y. Thanks in advance !

Questions about converged infrastructure setup and glusterFS sizing/performance
by Jayme 22 Jan '18

22 Jan '18

I am attempting to narrow down choices for storage in a new oVirt build that will eventually be used for a mix of dev and production servers. My current space usage excluding backups sits at about only 1TB so I figure 3-5 TB would be more than enough for VM storage only + some room to grow. There will be around 24 linux VMs total but 80% of them are VERY low usage and low spec servers. I've been considering a 3 host hyperconverged oVirt setup, replica 3 arbiter 1 setup with a disaster recovery plan to replicate the gluster volume to a separate server. I would of course do additional incremental backups to an alternate server as well probably with rsync or some other method. Some questions: 1. Is it recommended to use SSDs for glusterFS or can the performance of regular server/sas drives be sufficient enough performance. If using SSDs is it recommended to use enterprise SSDs are consumer SSDs good enough due to the redundancy of glusterFS? I would love to hear of any use cases from any of you regarding hardware specs you used in hyperconverged setups and what level of performance you are seeing. 2. Is it recommended to RAID the drives that form the gluster bricks? If so what raid level? 3. How do I calculate how much space will be usable in a replicate 3 arbiter 1 configuration? Will it be 75% of total drive capacity minus what I lose from raid (if I raid the drives)? 4. For replication of the gluster volume, is it possible for me to replicate the entire volume to a single drive/raid array in an alternate server or does the replicated volume need to match the configuration of the main glusterFS volume (i.e. same amount of drives/configuration etc). 5. Has the meltdown bug caused or expected to cause major issues with oVirt hyperconverged setup due to performance loss from the patches. I've been reading articles suggesting up to 30% performance loss on some converged/storage setups due to how CPU intensive converged setups are. Thanks in advance!

OVS not running / logwatch error after upgrade from 4.0.6 to 4.1.8
by Derek Atkins 21 Jan '18

21 Jan '18

Hi, I recently upgraded my 1-host ovirt deployment from 4.0.6 to 4.1.8. Since then, the host has been reporting a cron.daily error: /etc/cron.daily/logrotate: logrotate_script: line 4: cd: /var/run/openvswitch: No such file or directory This isn't surprising, since: # systemctl status openvswitch ● openvswitch.service - Open vSwitch Loaded: loaded (/usr/lib/systemd/system/openvswitch.service; disabled; vendor preset: disabled) Active: inactive (dead) The host was just upgraded by "yum update". Was there anything special that needed to happen after the update? Do I *NEED* OVS running? The VMs all seem to be behaving properly. Thanks, -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant
