Configuring LDAP backend in non interactive mode
by Luca 'remix_tj' Lorenzetto 30 Nov '17

30 Nov '17

Hello, i'm looking for some examples on how to configure LDAP authn and authz in non interactive mode. I'd like to add some authentication sources immediately after hosted-engine deployment. I've seen that ovirt-engine-extension-aaa-ldap-setup has an option config-append. Help refers to an answer file, but i can't find out how to generate it. All the servers i'm deploying should use the same configurations to access to 3 different active directory servers. Anyone has experiences about this?

Migration from Proxmox to oVirt
by Gabriel Stein 30 Nov '17

30 Nov '17

Hi again! well, I'm trying to migrate all my VMs from Proxmox to oVirt. Proxmox doesn't have libvirt and I can dump the files using vzdump <vm-id> <directory> and the output is a *.vma file I think from Proxmox. I can't even find the files, Proxmox create Logical Volumes for every VM. I converted that to *.qcow2 using qemu-img convert, the conversion worked(at least no errors) but I can't import it using a script that I found on web* and the export storage domain(oVirt didn't found it). I would like to know if there is a way to do that. I read a lot about and found that one could build a conversion server and use virt-v2v to import. But it will require a RH Enterprise for that, right? I don't have a subscription and I would like to know if is possible without the subscription? And sorry for the offtopic question, if there is a "redhat" which would like to answer me privately, if I buy a subscription for 1 Server and I have NN CentOS Servers, it will be possible to use all benefits since I have a valid subscription(of course, support just for the RH Server)? * https://rwmj.wordpress.com/2015/09/18/importing-kvm-guests-to-ovirt-or-rhev/ Thanks in Advance!

by Greg Sheremeta 29 Nov '17

Hi everyone, [I should have sent this message sooner -- apologies, and thanks to Martin Sivak for the reminder!] If you're trying out oVirt 4.2 Beta, please check that any existing UI plugins [1] you are using 1. still work (they should!), and 2. look good in the new UI. If something doesn't look quite right with a UI plugin [for example, if it doesn't quite match the new theme], please contact Alexander Wels and me and we can assist with getting it updated. [1] https://www.ovirt.org/develop/release-management/features/ux/uiplugins/ Best wishes, Greg -- GREG SHEREMETA SENIOR SOFTWARE ENGINEER - TEAM LEAD - RHV UX Red Hat NA <https://www.redhat.com/> gshereme(a)redhat.com IRC: gshereme <https://red.ht/sig>

Update gluster HCI from 4.1.3 to 4.1.7
by Gianluca Cecchi 28 Nov '17

28 Nov '17

Hello, I have an environment with 3 hosts and gluster HCI on 4.1.3. I'm following this link to take it to 4.1.7 https://www.ovirt.org/documentation/how-to/hosted-engine/#upgrade-hosted-en… The hosts and engine were at 7.3 prior of beginning the update. All went ok for the engine that now is on 7.4 (not rebooted yet) Points 4. 5. 6. for the first updated host were substituted by rebooting it I'm at point: 7. Exit the global maintenance mode: in a few minutes the engine VM should migrate to the fresh upgraded host cause it will get an higher score One note: actually exiting from global maintenance doesn't imply that the host previously put into maintenance exiting from it, correct? So in my workflow, before point 7., actually I have selected the host and activated it. Currently the situation is this - engine running on ovirt02 - update happened on ovirt03 Then after exiting from global maintenance I don't see the engine vm migrating to it. And in fact (see below) the score of ovirt02 is the same (3400) as the one of ovirt03, so it seems it is correct that engine remains there...? Which kind of messages should I see inside logs of engine/hosts?

"Cannot acquire bridge address" / Failure in "hosted-engine --deploy" on 4.1.8
by Frank Wall 28 Nov '17

28 Nov '17

Hi, when running "hosted-engine --deploy" on a fresh CentOS 7.4 with pre-built network configuration (and ovirtmgmt bridge), the following error occurs: 2017-11-27 19:08:12 DEBUG otopi.context context._executeMethod:142 method exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/otopi/context.py", line 132, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-common/network/bridge.py", line 295, in _get_hostname_from_bridge_if raise RuntimeError(_('Cannot acquire bridge address')) RuntimeError: Cannot acquire bridge address While checking the source of bridge.py line 295 the root cause is interesting: Running "vdsClient -s $HOSTNAME getVdsCapabilities" works perfectly, all NICs and bridges are returned, but only "networks" is returned as empty list: {}. Clearly looks like a bug. How can I resolve this issue? ovirt-hosted-engine-setup-2.1.4-1.el7.centos.noarch vdsm-4.19.40-1.el7.centos.x86_64 Regards - Frank

Time management in self hosted engine vm
by Gianluca Cecchi 28 Nov '17

28 Nov '17

Hello, I have a self hosted engine HCI environment that was born in 4.0.5 through the ansible/gdeploy mechanism and then gradually updated to 4.1.7 Now the engine and host are at CentOS 7.4 level. Inside the gdeploy jobs the engine vm was installed through the appliance at the 4.0.5 time. I see in web admin gui that hw clock of engine vm is configured as UTC (so far so good) and the same is inside the OS. And I would like to change it to UTC+1 like the 3 hosts I also see that neither chronyd nor ntpd are installed on engine vm. Can I fix the situation the normal os level way: - timedatectl set-timezone "Europe/Rome" - install and configure chronyd or better not to configure time sync in engine vm? Thanks, Gianluca
