ovirt - in docker
by ReSearchIT Eng
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
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
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
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?
Best regards,
Mark

ovirt 4.2.6 and cockpit with plain hosts
by Gianluca Cecchi
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

and on the host

----------. 1 root root 0 May 24 16:18 /run/cron.reboot
[root@ov300 ~]#
Is this a bug? Can I manually create the " /run/cockpit" directory?
Thanks,

Migrating to Gluster HCI - Export/Import
by Vincent Royer
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!
