Re: [ovirt-users] providing hosts with foreman
by Oved Ourfali 22 May '15

22 May '15

At this step, after the host installation was successful, which means iirc that all puppet classes were applied correctly, the plug in on the foreman side handles the bootstrapping of the new host. Attaching the production.log file on Foreman, and the engine.log from the ovirt engine is needed to understand what went wrong. A workaround is to remove the host, and add it back. Iirc we haven't allowed reinstall for the installing-OS status.

providing hosts with foreman
by Nathanaël Blanchet 22 May '15

22 May '15

Hi all, I've setup a foreman server, but when adding a new host by "discovered hosts", I can't modify the address item which is default filled with a built "mac-DNS". In ovirt setup, I want to identify my future hosts by their IP and not their unknown DNS name like it is described here: http://www.ovirt.org/Features/ForemanIntegration. How can I setup foreman to do such a thing? Is the setup of the DNS proxy related? -- 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

vdsmd fails to start on boot
by Chris Jones - BookIt.com Systems Administrator 21 May '15

21 May '15

Running oVirt Node - 3.5 - 0.999.201504280931.el7.centos. On first boot, vdsmd fails to load with "Dependency failed for Virtual Desktop Server Manager." When I run "systemctl start vdsmd" it loads fine. This happens on every reboot. Looks like there is an old bug for this from 3.4. https://bugzilla.redhat.com/show_bug.cgi?id=1055153 -- This email was Virus checked by UTM 9. For issues please contact the Windows Systems Admin.
