by TranceWorldLogic . 03 Aug '17

03 Aug '17

Hi, I was going through gluster document it was talking about libgfapi, that gives better performance. And I also went through many bug description and comment and mail thread in ovirt group. But still not understood, how to enable libgfapi ? Is it supported in 4.1 ? I am confuse. Please help me to understand whether it supported or not. If supported, then how can I enable it ? or use it ? Thanks, ~Rohit

oVirt 3.6.x and Centos 6.9
by Neil 02 Aug '17

02 Aug '17

Hi guys, I upgraded to the latest ovirt-engine-3.6.7.5-1.el6.noarch available in the ovirt 3.6 repo, however I seem to be encountering a known bug ( https://bugzilla.redhat.com/show_bug.cgi?id=1387949) which looks to be fixed in ovirt 3.6.9.2 but I can't seem to find out how to install this. I was hoping it was via http://resources.ovirt.org/pub/ovirt-3.6-snapshot but this link is dead. Is anyone using ovirt 3.6.9 and how does one obtain it? The issues I'm facing is, after trying to update my cluster version to 3.6, my hosts weren't compatible, as it says they only compatible with version 3.3, 3.4 and 3.5 etc. I then upgraded 1 hosts to Centos 6.9 and installed and updated the latest vdsm from the 3.6 repo, but this still didn't allow me to change my cluster version. I then rolled back the cluster version to 3.5. At the moment because I've upgraded 1 host, I can't select this host as SPM and I'm wondering if I can upgrade my remaining hosts, or will this prevent any hosts from being my SPM? I'm seeing the following error "WARNING Unrecognized protocol: 'SUBSCRI'" on my upgraded host. I'm wanting to upgrade to the latest 3.6 as well as upgrade all my hosts, so that I can start the ovirt 4 upgrade next. Please could I have some guidance on this? Thank you. Regards. Neil Wilson.

sanlock ids file broken after server crash
by Johan Bernhardsson 02 Aug '17

02 Aug '17

Hello, The ids file for sanlock is broken on one setup. The first host id in the file is wrong. >From the logfile i have: verify_leader 1 wrong space name 0924ff77-ef51-435b-b90d-50bfbf2e�ke7 0924ff77-ef51-435b-b90d-50bfbf2e8de7 /rhev/data-center/mnt/glusterSD/ Note the broken char in the space name. This also apears. And it seams as the hostid too is broken in the ids file: leader4 sn 0924ff77-ef51-435b-b90d-50bfbf2e�ke7 rn ��7afa5-3a91-415b- a04c-221d3e060163.vbgkvm01.a ts 4351980 cs eefa4dd7 Note the broken chars there as well. If i check the ids file with less or strings the first row where my vbgkvm01 host are. That has broken chars. Can this be repaired in some way without taking down all the virtual machines on that storage? /Johan

VDSM Command failed: Heartbeat Exceeded
by Neil 02 Aug '17

02 Aug '17

Hi guys, Please could someone assist me, my DC seems to be trying to re-negotiate SPM and apparently it's failing. I tried to delete an old autogenerated snapshot and shortly after that the issue seemed to start, however after about an hour, the snapshot said successfully deleted, and then SPM negotiated again albeit for a short period before it started trying to re-negotiate again. Last week I upgraded from ovirt 3.5 to 3.6, I also upgraded one of my 4 hosts using the 3.6 repo to the latest available from that repo and did a yum update too. I have 4 nodes and my ovirt engine is a KVM guest on another physical machine on the network. I'm using an FC SAN with ATTO HBA's and recently we've started seeing some degraded IO. The SAN appears to be alright and the disks all seem to check out, but we are having rather slow IOPS at the moment, which we trying to track down. ovirt engine CentOS release 6.9 (Final) ebay-cors-filter-1.0.1-0.1.ovirt.el6.noarch ovirt-engine-3.6.7.5-1.el6.noarch ovirt-engine-backend-3.6.7.5-1.el6.noarch ovirt-engine-cli-3.6.2.0-1.el6.noarch ovirt-engine-dbscripts-3.6.7.5-1.el6.noarch ovirt-engine-extension-aaa-jdbc-1.0.7-1.el6.noarch ovirt-engine-extensions-api-impl-3.6.7.5-1.el6.noarch ovirt-engine-jboss-as-7.1.1-1.el6.x86_64 ovirt-engine-lib-3.6.7.5-1.el6.noarch ovirt-engine-restapi-3.6.7.5-1.el6.noarch ovirt-engine-sdk-python-3.6.7.0-1.el6.noarch ovirt-engine-setup-3.6.7.5-1.el6.noarch ovirt-engine-setup-base-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-ovirt-engine-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-ovirt-engine-common-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-vmconsole-proxy-helper-3.6.7.5-1.el6.noarch ovirt-engine-setup-plugin-websocket-proxy-3.6.7.5-1.el6.noarch ovirt-engine-tools-3.6.7.5-1.el6.noarch ovirt-engine-tools-backup-3.6.7.5-1.el6.noarch ovirt-engine-userportal-3.6.7.5-1.el6.noarch ovirt-engine-vmconsole-proxy-helper-3.6.7.5-1.el6.noarch ovirt-engine-webadmin-portal-3.6.7.5-1.el6.noarch ovirt-engine-websocket-proxy-3.6.7.5-1.el6.noarch ovirt-engine-wildfly-8.2.1-1.el6.x86_64 ovirt-engine-wildfly-overlay-8.0.5-1.el6.noarch ovirt-host-deploy-1.4.1-1.el6.noarch ovirt-host-deploy-java-1.4.1-1.el6.noarch ovirt-image-uploader-3.6.0-1.el6.noarch ovirt-iso-uploader-3.6.0-1.el6.noarch ovirt-release34-1.0.3-1.noarch ovirt-release35-006-1.noarch ovirt-release36-3.6.7-1.noarch ovirt-setup-lib-1.0.1-1.el6.noarch ovirt-vmconsole-1.0.2-1.el6.noarch ovirt-vmconsole-proxy-1.0.2-1.el6.noarch node01 (CentOS 6.9) vdsm-4.16.30-0.el6.x86_64 vdsm-cli-4.16.30-0.el6.noarch vdsm-jsonrpc-4.16.30-0.el6.noarch vdsm-python-4.16.30-0.el6.noarch vdsm-python-zombiereaper-4.16.30-0.el6.noarch vdsm-xmlrpc-4.16.30-0.el6.noarch vdsm-yajsonrpc-4.16.30-0.el6.noarch gpxe-roms-qemu-0.9.7-6.16.el6.noarch qemu-img-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.479.el6_7.2.x86_64 libvirt-0.10.2-62.el6.x86_64 libvirt-client-0.10.2-62.el6.x86_64 libvirt-lock-sanlock-0.10.2-62.el6.x86_64 libvirt-python-0.10.2-62.el6.x86_64 node01 was upgraded out of desperation after I tried changing my DC and cluster version to 3.6, but then found that none of my hosts could be activated out of maintenance due to an incompatibility with 3.6 (I'm still not sure why as searching seemed to indicate Centos 6.x was compatible. I then had to remove all 4 hosts, and change the cluster version back to 3.5 and then re-add them. When I tried changing the cluster version to 3.6 I did get a complaint about using the "legacy protocol" so on each host under Advanced, I changed them to use the JSON protocol, and this seemed to resolve it, however once changing the DC/Cluster back to 3.5 the option to change the protocol back to Legacy is no longer shown. node02 (Centos 6.7) vdsm-4.16.30-0.el6.x86_64 vdsm-cli-4.16.30-0.el6.noarch vdsm-jsonrpc-4.16.30-0.el6.noarch vdsm-python-4.16.30-0.el6.noarch vdsm-python-zombiereaper-4.16.30-0.el6.noarch vdsm-xmlrpc-4.16.30-0.el6.noarch vdsm-yajsonrpc-4.16.30-0.el6.noarch gpxe-roms-qemu-0.9.7-6.14.el6.noarch qemu-img-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.479.el6_7.2.x86_64 libvirt-0.10.2-54.el6_7.6.x86_64 libvirt-client-0.10.2-54.el6_7.6.x86_64 libvirt-lock-sanlock-0.10.2-54.el6_7.6.x86_64 libvirt-python-0.10.2-54.el6_7.6.x86_64 node03 CentOS 6.7 vdsm-4.16.30-0.el6.x86_64 vdsm-cli-4.16.30-0.el6.noarch vdsm-jsonrpc-4.16.30-0.el6.noarch vdsm-python-4.16.30-0.el6.noarch vdsm-python-zombiereaper-4.16.30-0.el6.noarch vdsm-xmlrpc-4.16.30-0.el6.noarch vdsm-yajsonrpc-4.16.30-0.el6.noarch gpxe-roms-qemu-0.9.7-6.14.el6.noarch qemu-img-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-0.12.1.2-2.479.el6_7.2.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.479.el6_7.2.x86_64 libvirt-0.10.2-54.el6_7.6.x86_64 libvirt-client-0.10.2-54.el6_7.6.x86_64 libvirt-lock-sanlock-0.10.2-54.el6_7.6.x86_64 libvirt-python-0.10.2-54.el6_7.6.x86_64 node04 (Centos 6.7) vdsm-4.16.20-1.git3a90f62.el6.x86_64 vdsm-cli-4.16.20-1.git3a90f62.el6.noarch vdsm-jsonrpc-4.16.20-1.git3a90f62.el6.noarch vdsm-python-4.16.20-1.git3a90f62.el6.noarch vdsm-python-zombiereaper-4.16.20-1.git3a90f62.el6.noarch vdsm-xmlrpc-4.16.20-1.git3a90f62.el6.noarch vdsm-yajsonrpc-4.16.20-1.git3a90f62.el6.noarch gpxe-roms-qemu-0.9.7-6.15.el6.noarch qemu-img-0.12.1.2-2.491.el6_8.1.x86_64 qemu-kvm-0.12.1.2-2.491.el6_8.1.x86_64 qemu-kvm-tools-0.12.1.2-2.503.el6_9.3.x86_64 libvirt-0.10.2-60.el6.x86_64 libvirt-client-0.10.2-60.el6.x86_64 libvirt-lock-sanlock-0.10.2-60.el6.x86_64 libvirt-python-0.10.2-60.el6.x86_64 I'm seeing a rather confusing error in the /var/log/messages on all 4 hosts as follows....

We are in the process of expanding the SAN Array too, but we trying to get to the bottom of the bad IOPS at the moment before adding on addition overhead. Ping tests between hosts and engine all look alright, so I don't suspect network issues. I know this is very vague, everything is currently operational, however as you can see in the attached logs, I'm getting lots of ERROR messages. Any help or guidance is greatly appreciated. Thanks.

Pass Discard guest OS support?
by Doug Ingham 01 Aug '17

01 Aug '17

Hi All, Just today I noticed that guests can now pass discards to the underlying shared filesystem. http://www.ovirt.org/develop/release-management/features/storage/pass-disca… Is this supported by all of the main Linux guest OS's running the virt agent? And what about Windows guests? (specifically, 2012 & 2016) Cheers, -- Doug

oVirt and Foreman
by Davide Ferrari 01 Aug '17

01 Aug '17

Hello list is anybody successfully using oVirt + Foreman for VM creation + provisioning? I'm using Foremn (latest version, 1.15.2) with latest oVirt version (4.1.3) but I'm encountering several problem, especially related to disks. For example: - cannot create a VM with multiple disks though Foreman CLI (hammer) - if I create a multidisk VM from Foreman, the second disk always gets the "bootable" flag and not the primary image, making the VMs not bootable at all. Any other Foreman user sharing the pain here? Foramn's list is not so useful so I'm trying to ask here. How do you programmatically create virtual machines with oVirt and Foreman? Should I switch do directly using oVirt API? Thanks in advance Davide

Deploying training lab
by Andy Michielsen 01 Aug '17

01 Aug '17

Hello all, Don't know if this is the right place to ask this but I would like to set up a trainingslab with oVirt. I have deployed an engine and a host with local storage and want to run 1 server and 5 desktops off it. But the desktops will be used on thin clients or old laptops with some minimal os installation running spice client or a webbrowser. I was wondering if anyone can give me pointer in how to set up a minimal laptop which only need to run an spice client. Kind regards.

Re: [ovirt-users] Yum error while installing host on Centos7
by Yanir Quinn 01 Aug '17

01 Aug '17

where did you manually install the packages ? engine or host machine ? you can you provide the engine.log to see what might cause the error on the engine's side. maybe rollback the last yum transaction you did and try to run the engine again. as far as for the host installation you might need to check the exiting repositories (Cenots or other existing repos on the machine) , its not recommended to use --skip-broken usually when adding a host.
