by ReSearchIT Eng 10 Oct '18

10 Oct '18

Hello! I am interested to run ovirt in docker container. It was noticed that there is an official repo for it: https://github.com/oVirt/ovirt-container-engine Unfortunately it did not get an update for 2 years (4.1). Can anyone help with the required answers/entrypoint/patch files for the new 4.2 ? Thanks!

IPoIB broken with ovirt 4.2.6
by Giulio Casella 10 Oct '18

10 Oct '18

Hi, latest ovirt node stable (4.2.6 today) introduced a bug in kernel: IP over infiniband is not workingh anymore after an upgrade, due to kernel 3.10.0-862.11.6.el7.x86_64. You can find some detail here: https://bugs.centos.org/view.php?id=15193 dmesg is full of "failed to modify QP to RTR: -22", and the networking stack (in my case used to connect to storage) is broken. The interface can obtain an address via DHCP, but also a simple ICMP ping fails. Does someone have news about a fix for this issue? TIA, Giulio

Power Management connection to Citrix Studio
by jtxtm25＠gmail.com 09 Oct '18

09 Oct '18

Hello, Making a transition into Ovirt from XenServer. Does anyone know of any resources around configuring Ovirt with Citrix Studio? Referencing: Studio > Configuration > Hosting > Add Connection and Resources Connection Types Citrix XenServer Microsoft System Center Virtual Machine Manager VMware vSphere CloudPlatform Microsoft Azure Microsoft Azure Classic Amazon EC2 Microsoft Configuration Manager Wake on LAN Mapping to the hypervisor from Studio is required to take advantage of power management features. Has anyone found a way to map directly to Ovirt? Thanks, Jake

Moving to new storage questions
by Mark Steele 09 Oct '18

09 Oct '18

Good morning, We are in the process of moving our oVirt installation to a new storage solution. We have been 'move'-ing VM disks to the new storage without issue. We have several templates that use the old storage device - is there an equivalent process for moving template disks to the new storage unit? I see there is a 'copy' function in the template disk screen which creates a disk in the new storage domain. Can I then remove the original disk image from the original domain?

ovirt 4.2.6 and cockpit with plain hosts
by Gianluca Cecchi 09 Oct '18

09 Oct '18

Is cockpit supposed to run on plain CentOS hosts? I didn't have it installed: possibly because it started as a hypervisor host in version 3.x when cockpit not available. During updates it has not put in as a requirement package. I manually installed it and then enabled/started the cockpit.socket systemd unit. It seems started and I can correctly connect to https at tcp port 9090, but when doing a status of the cockpit.socket unit I see Oct 09 15:59:01 ov300 update-motd[22990]: /usr/share/cockpit/motd/update-motd: line 24: /run/cockpit/active.motd: No such file or directory Oct 09 15:59:01 ov300 ln[22998]: /bin/ln: failed to create symbolic link ‘/run/cockpit/motd’: No such file or directory Oct 09 15:59:01 ov300 systemd[1]: Listening on Cockpit Web Service Socket.

Migrating to Gluster HCI - Export/Import
by Vincent Royer 09 Oct '18

09 Oct '18

I'm upgrading from 2 host w/ attached storage to 3-host HCI w/Gluster. What is the procedure for this? Is export domain depreciated? 1. Shut down and export all VMs - Do I use export domain? Or is the "Backup Domain" the newer method? 2. Detach domains from cluster and wipe hosts 3. Build HCI cluster, setup gluster bricks/vols 4. Attach backup domain and import VMs Thanks! Vincent

by Alex K 09 Oct '18

09 Oct '18

Hi all, I am running ovirt 4.2 with hosts based on CentOS 7. I see that the latest guest tools are the following: https://resources.ovirt.org/pub/ovirt-4.2/iso/oVirt-toolsSetup/4.2-3.el7/oV… https://resources.ovirt.org/pub/ovirt-4.2/iso/oVirt-toolsSetup/4.2-1.el7.ce… 4.2-3.el7 seems to have newer version than 4.2-1.el7.centos. Can I use 4.2-3.el7 ISO? Thanx, Alex
