[DOC] Upgrade guide from 3.6 el6 to 4.0 el7
by Sandro Bonazzola 19 Jul '16

19 Jul '16

Hi, for those who missed it, a guide has been created to help migrating from 3.6 running on EL6 to 4.0 running on EL7 which also applies to 3.6 on FC22 to 4.0 on FC23. You can find the guide here: http://www.ovirt.org/documentation/migration-engine-3.6-to-4.0/ For hosted engine a guide is under review on GitHub here: https://github.com/oVirt/ovirt-site/pull/296 pending to fix some issue with travis build. If you're doing an upgrade with OS migration, feedback, suggestions and improvements are welcome. Thanks, -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

oVirt + Gluster Hyperconverged
by Fernando Frediani 18 Jul '16

18 Jul '16

Hi folks, I have a few servers with reasonable amount of raw storage but they are 3 with only 8GB of memory each. I wanted to have them with an oVirt Hyperconverged + Gluster mainly to take advantage of the amount of the storage spread between them and have ability to live migrate VMs. Question is: Does running Gluster on the same Hypervisor nodes consumes any significant memory that won't be much left for running VMs ? Thanks Fernando

deploying ovirt 3.6 engine on a glustered storage
by Andy Michielsen 18 Jul '16

18 Jul '16

Hello, I'm trying to install a new oVirt enviroment at my company but I'm having troubles installing the engine on the /gluster/engine/brick as it is not in replica 3 mode. I want to install it first on 1 host as I have only 1 host available at the moment. Afterwards I will add 2 additional host but I need to get past this replica 3 requirement first now. How can I accomplish this ? Kind regards

centos 7.1 and up & ixgbe
by Johan Kooijman 18 Jul '16

18 Jul '16

Hi all, Since we upgraded to the latest ovirt node running 7.2, we're seeing that nodes become unavailable after a while. It's running fine, with a couple of VM's on it, untill it becomes non responsive. At that moment it doesn't even respond to ICMP. It'll come back by itself after a while, but oVirt fences the machine before that time and restarts VM's elsewhere. Engine tells me this message: VDSM host09 command failed: Message timeout which can be caused by communication issues Is anyone else experiencing these issues with ixgbe drivers? I'm running on Intel X540-AT2 cards. -- Met vriendelijke groeten / With kind regards, Johan Kooijman

Re: [ovirt-users] CARP Fails on Bond mode=1
by Matt . 18 Jul '16

18 Jul '16

How can it lead into packet duplication when the passive should not be active and only it's mac-address should be visible on the switch to prevent confusion on the switch ? For a VRRP setup on the switch there is no other option then mode=1 as far as I know ? 2016-07-13 14:50 GMT+02:00 Pavel Gashev <Pax(a)acronis.com>: > I would say that bonding breaks CARP somehow. In example mode=1 can lead to packet duplication, so pfsense can receive it's own packets.

Debian linux and oVirt SSO
by Tadas 18 Jul '16

18 Jul '16

Hello, i'm struggling to get oVirt SSO working on Linux guest VM. I can confirm, that SSO is fully functional on Windows guest (please note it's not a full oVirt installation - I'm just testing oVirt guest agent on virtual machines running on plain KVM hypervisor). Steps I've made: got oVirt guest agent up and running, I can communicate with it from hypervisor: socat /var/lib/libvirt/qemu/channel/target/domain-80-KDE64_1/com.kvm- vdi.0 - {"__name__": "os-version", "version": "4.6.0-1-amd64"} Compiled and copied pam_ovirt_cred.so to /lib/x86_64-linux-gnu/security Configured /etc/pam.d/kdm-ovirt-cred with: %PAM-1.0 auth required pam_ovirt_cred.so auth include password-auth account include password-auth password include password-auth session required pam_selinux.so close session required pam_selinux.so open session include password-auth Compiled and copied kgreet_ovirtcred.so to /usr/lib/kde4 Configured /etc/kde4/kdm/kdmrc with: PluginsLogin=ovirtcred Symptoms: After starting kdm, I get login prompt with barely visible title (I assume it should spell "oVirt Authentication" from kgreet_ovirtcred.cpp). Username and password boxes are inactive - i cannot enter anything to them. After emitting username/password to oVirt agent, I can see the following log entries: Dummy-1::INFO::2016-07-15 12:29:51,628::CredServer::207::root::The following users are allowed to connect: [0] Dummy-1::INFO::2016-07-15 12:29:51,629::CredServer::273::root::Opening credentials channel... Dummy-1::INFO::2016-07-15 12:29:51,629::CredServer::132::root::Emitting user authenticated signal (509542). CredChannel::INFO::2016-07-15 12:29:56,634::CredServer::241::root::Credentials channel timed out. The only thing that worries me, - are the entries in kdm.log file: klauncher(6100) kdemain: No DBUS session-bus found. Check if you have started the DBUS server. Since oVirt guest agent sends wakeup message to greeter plugin via Dbus, perhaps this is the problem? Maybe someone had the same problem here? This happens on Debian 8 and 9. Thank you.
