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 I guess the documentation on oVirt site (https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks/) is outdated with respect to FCoE.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?

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 22 Jan '18

22 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

correct settings for gluster based storage domain
by Artem Tambovskiy 19 Jan '18

19 Jan '18

I'm still troubleshooting the my oVirt 4.1.8 cluster and idea came to my mind that I have an issue with storage settings for hosted_engine storage domain. But in general if I have a 2 ovirt nodes running gluster + 3rd host as arbiter, how the settings should looks like? lets say I have a 3 nodes: ovirt1.domain.com (gluster + ovirt) ovirt2.domain.com (gluster + ovirt) ovirt3.domain.com (gluster) How the correct storage domain config should looks like? Option 1: /etc/ovirt-hosted-engine/hosted-engine.conf .... storage=ovirt1.domain.com:/engine mnt_options=backup-volfile-servers=ovirt2.domain.com:ovirt3.domain.com Option 2: /etc/ovirt-hosted-engine/hosted-engine.conf .... storage=localhost:/engine mnt_options=backup-volfile-servers=ovirt1.domain.com:ovirt2.domain.com:o virt3.domain.com Option 3: Setup a DNS record gluster.domain.com pointing to IP addresses of gluster nodes /etc/ovirt-hosted-engine/hosted-engine.conf .... storage=gluster.domain.com:/engine mnt_options= Of course its related not only to hosted engine domain, but to all gluster based storage domains. Thank you in advance! Regards, Artem

Q: Optimal settings for DB hosting
by andreil1 19 Jan '18

19 Jan '18

Hi ! What is optimal setting for oVirt KVM guests for database hosting on Xeon server (2 x Xeon 4-core each) (in my case this is Firebird based accounting/stock control system with several clients active)? 1st of course its preallocated disk image. VirtO-SCSI enabled Migration disabled. Balloning disabled. CPU shares disabled Pass-through host CPU enabled What should be other CPU settings? 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? Any idea of NUMA settings ? Node running 4 VMs total, CPU load is quite low, RAM is enough to preallocate for each VM + 4GB for node itself. Thanks in advance ! Andrei

The future of backups in oVirt 4.2+
by Jayme 19 Jan '18

19 Jan '18

I've been running a non-production oVirt setup for a while and plan on building a more robust oVirt setup for eventual production use. Part of that planning of course is backup/disaster recovery options. I've been playing around with a few options to backup oVirt, I'm sure most of you are aware of them. The github webfix it python scripts, and starting to look at bacchus as well although have not set it up or tested bacchus yet. The webfix it python script is fairly simple to setup and seems to work ok as intended, even on 4.2, but it's definitely clunky in terms of having to snapshot, clone, export. A lot of resource usage. I assume bacchus most likely uses the same method of snapshot/clone/export as well (due to what was available in oVirt at the time these scripts were written). My concerns with using something like these are: 1. It's using old 3x api -- which is fine for now but probably not with oVirt 4.3 2. Inefficient / resource intensive 3. Using export domain which is depreciated >From what I've read in oVirt documentation the Export domain is depreciated. I assume that this means that instead of a export domain you could instead create a regular data domain for backups that can be detached and attached to another environment, is that the correct assumption? I've also read that it might be possible to skip the cloning of the VM part and export snapshots directly. Is this now possible in 4.2 or will be in the future? if it is possible to perform VM backups without cloning to a new VM first is anyone aware of any scripts/software that is available now which takes advantage of that? Essentially all I want is a simple solution to backup my VMs to separate NFS storage. If for some reason my main storage crashes I then have the option to connect that backup NFS storage to a secondary stand alone oVirt instance and run my VMs from there until the primary oVirt instance is repaired. What I want to avoid is implementing an older more inefficient solution that might work for a while but will eventually no longer work due to ovIrt updates in the future. I know options like active-active failover and georeplication exist but that may be too complex for my needs although I would be interested in hearing about how some of you may be implementing these features. In summary, I'd trying to figure out what the best backup option may be going forward with oVirt in the future so I can implement the best option from the start rather than having to change it all around in the near future. Thanks!

Zombie kworker process on node took 100% CPU load
by Andrei V 18 Jan '18

18 Jan '18

Hi, I've got strange problem with oVirt Node 4.2 installed on CentOS 7 with mainline 4.14 kernel & HP ProLiant ML350. Kworker process loaded 1 cpu CPU core at 100%, and since it didn't finish even after several hours, it was clearly a zombie. I logged into each VM, and powered them off with "shutdown now". From SPICE console it was seen VMs halted. However, in oVirt engine web they have been marked with tripple green down arrow. An attempt to shutdown them completely with oVirt button resulted in error message something like "Can't shutdown VM because highly available and can't be moved". Sorry, I forgot to take screenshot. Its was also impossible to shutdown the node correctly, process freezes. After restart, everything seem to work correctly. Anyone have any idea how to cope with this kind of problem? Thanks in advance Andrei

docker, kubernetes and ovirt
by Nathanaël Blanchet 18 Jan '18

18 Jan '18

Hi all, Regarding to this video : https://www.youtube.com/watch?v=JyyST4ZKne8 and ovedou.blogspot.fr/2014/03/running-docker-container-in-ovirt.html, it appears that some stuff has been done in integrated docker into ovirt. I'm interested into these two UI plugins : docker-resources (I found it in samples-uiplugins) and the kubernetes one that I didn't find anywhere. Can anyone tell me if the development of that projects are definitively stopped and the reason why? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

oVirt Node 4.1.8 -> 4.2 upgrade
by Ed Stout 18 Jan '18

18 Jan '18

Good Morning, Perhaps someone could clarify for me, please - to update oVirt Nodes from 4.1.8 -> 4.2, should I just be able to yum install the 4.2 release file, then yum update? Or, do I have to start with the 4.2 ISO then update from there? When I try the former it fails with dependency issues for the nodes, I did however manage to update a self hosted appliance engine to 4.2. I had a read through the mailing list archive and couldn't find similar issues, so perhaps I'm doing something wrong. --> Processing Dependency: lshw for package: vdsm-4.20.9.3-1.el7.centos.x86_64 --> Finished Dependency Resolution Error: Package: ovirt-hosted-engine-setup-2.2.3-1.el7.centos.noarch (ovirt-4.2) Requires: libvirt-daemon-config-network Error: Package: ovirt-hosted-engine-setup-2.2.3-1.el7.centos.noarch (ovirt-4.2) Requires: virt-install Error: Package: glusterfs-geo-replication-3.12.3-1.el7.x86_64 (ovirt-4.2-centos-gluster312) Requires: python-prettytable Error: Package: vdsm-4.20.9.3-1.el7.centos.x86_64 (ovirt-4.2) Requires: lshw Error: Package: glusterfs-events-3.12.3-1.el7.x86_64 (ovirt-4.2-centos-gluster312) Requires: python-prettytable You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest OS Version: RHEL - 7 - 4.1708.el7.centos OS Description: oVirt Node 4.1.8 Kernel Version: 3.10.0 - 693.11.1.el7.x86_64 KVM Version: 2.9.0 - 16.el7_4.8.1 LIBVIRT Version: libvirt-3.2.0-14.el7_4.5 VDSM Version: vdsm-4.19.43-1.el7.centos SPICE Version: 0.12.8 - 2.el7.1 GlusterFS Version: glusterfs-3.8.15-2.el7 CEPH Version: librbd1-0.94.5-2.el7 Cheers, Ed

4.1.8: Run Once does not allow me to choose a CD Image to attach
by Derek Atkins 18 Jan '18

18 Jan '18

Hi, I upgraded from 4.0.6 to 4.1.8. I had created a VM in 4.0.6 but had never started it nor had I ever run it before I upgraded. I then upgraded to 4.1.8 (which went very smoothly), but then I tried to use the Run Once function to boot up and attach an ISO Image. However when I select Run Once, then Boot Options, the "Attach CD" option is unchecked and wont let me select it like I could in 4.0.6. If I try to select the checkbox I see the popup flash but the box remains unchecked. Is this a bug/regression in 4.1.8? I did clear my browser cache thinking that might be it, but no, that didn't help. The only thing I could do was Edit the VM, go to Boot options, select it there (which I could do) and then choose the ISO. THEN I could run it with the CD attached. Thanks, -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

Every User could see his VM=B4s, every Admi= n just could see his VM=B4s ( User View ). After the Update: Admin=B4s can see every VM in VM Portal The Users can=B4t see Vm=B4s anymore. The Portal is Empty. Role "UserVMMana= ger" is set. We tested some Scenarios: If the User create a new Virtual Machine, it is s= hown in the VM Portal. When he log out and in again -> VM is gone in his Vi= ew Admin View: The VM was created, Permission where set. Everything seems to b= e good. Any Ideas?
