[ovirt-users] Cinderlib db not contained in engine-backup
Dear oVirt users, I just noticed that the ovirt_cinderlib database does not seem to be contained in the archive file created by engine-backup. Is it missing there? Or is there any other way to restore the data of the ovirt_cinderlib database in case a restore the engine-backup would be required?

Re: [ovirt-users] Hosted Engine won't start, how to debug?
Dear Martin,
a follow up question regarding this case:
we managed to get the hosted engine up and running again, but we'd like
to permanently add the missing graphics device to the vm.conf (instead
of starting with the vm-custom.conf in case of trouble).
How do I add this line to the vm.conf config file (it seems to be
overwritten after a few seconds - I suppose it's copied from somewhere?)
Thanks,
Thomas

Re: [ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?
Hi Martin, I fully understand. The only reason is that it's not only me administering this oVirt setup, it's a setup for a client that has 2 local administrators. We are trying to eliminate any configuration that might cause confusion. When doing a hosted-engine --vm-status a list like this is shown: --== Host 1 status ==-- ... Hostname : ovirt1.munk.de Host ID : 1 ... --== Host 2 status ==-- ... Hostname : ovirt3.munk.de Host ID : 2 ... and so on. This "Host 2" -> ovirt3 will sooner or later cause confusion and will lead to administrative actions applied to the wrong hosts. I'll give it a try and try to align the hosts and ids. I'll backup the old values in order to be able to roll back the changes if it does not work. Thanks for your help!! Best regards, Thomas > Hi Thomas, > > is there a real need to have them aligned?

Re: [ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?
Dear Simone, thanks for the help, I already have noticed, that there is a mismatch between SPM IDs and the hosts. >From my knowledge this may be our fault. vds_name | vds_spm_id oVirt4 | 3 oVirt2 | 4 oVirt6 | 6 oVirt5 | 5 oVirt1 | 1 oVirt3 | 2 oVirt3 was re-installed using the node ng image - and was assigned id 2 that was available at that time (taken into account this database query). It was not available in fact because of the host ovirt2 having the host_id=2 entry in the configuration on the host and the sanlock having locked the appropriate space. I can't remember where this mismatch came from but I assume that some time ago someone maybe manually changed the entry on oVirt2 host in order to match with the hostname (oVirtX -> Host id X). Thus I think it is not a bug at the moment. But that leads me to the next question: Is there a manual way to align numbers in the hostnames with the SPM IDs? (oVirt4 should be spm id 4) Does this work? Update the database, change the entry in hosted-engine.conf and then reboot the node?

[ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?
Dear oVirt Users, we installed a third ovirt node using the ovirt node ng image (4.2.2), and added that node using the web interface of the hosted engine: Compute->Hosts->New - including the Hosted engine option "Choose hosted engine deployment action" set to "Deploy" After that we found out, that on the new node the host_id entry was causing problems. In /etc/ovirt-hosted-engine/hosted-engine.conf we found the entry ... host_id=2 ... But that host id already exists and was alive during deployment process. So my questions are: * How is the host id chosen (when adding a new host via GUI)? * Is there an option to preselect the host id in the GUI for a new node? * How can we prevent further duplicate host ids?

Re: [ovirt-users] Hosted Engine won't start, how to debug?
Dear Martin,
thanks, ok, good to know. We have a hosted engine that was created on
ovirt 3.x and after that has only been updated.
Maybe this is the cause.
Thanks for your help again.

Re: [ovirt-users] Hosted Engine won't start, how to debug?
Dear Martin,
yes, that worked. Thank you so much!!
We were able to see that the latest kernel update failed and did not
create the initramfs file and thus the boot process failed with a kernel
panic.
Debugging this problem took us many hours... It felt so complicated to
connect a vnc to this vm - compared to a bare metal setup with display
and keyboard.
Wouldn't it be a good idea to have the vnc device in the config by default?
Best regards,
Thomas

Re: [ovirt-users] Hosted Engine won't start, how to debug?
Dear Martin, thanks for the feedback. We already read this and tried it. It seems to me that the graphics device was removed from the hosted engine by some ovirt release. If I try to set a console password I see this message: hosted-engine --add-console-password Enter password: no graphics devices configured Furthermore, there is nothing listening on port 5900 after that. The HostedEngine qemu process shows a " -display none " as parameter and I have no idea where this can be changed. I already created a /var/run/ovirt-hosted-engine-ha/vm-custom.conf containing: display=vnc kvmEnable=true But nothing changed. I also edited the HostedEngine VM config using virsh and added a vnc display: /usr/bin/virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf edit HostedEngine But there is still "display none" passed as command line parameter to qemu and thus, I suppose, there's no display.

[ovirt-users] Hosted Engine won't start, how to debug?
Dear oVirt Team, after trying to reboot a hosted engine setup on oVirt 4.2 the VM won't come up anymore. The qemu-kvm process is there but we're unable to access the VM using - the serial console (simply does not show anything, does not react to characters typed) - VNC / Spice because the hosted engine vm.conf does not contain any graphics device. Before trying to reinstall, we'd like to recover and debug what is going on. We mounted a Centos7 install .iso and started the VM using hosted-engine --vm-start --vm-conf=/var/run/ovirt-hosted-engine-ha/vm-custom.conf But we still have to problem, that the serial console does not show anything and there is no way to connect using VNC. So, what is the recommended way to move forward in such situation? IMHO the classical way would be to add a graphics device and connect via VNC? I did not use the serial console much, up to now. Should the serial console show any output during boot? Thanks for your help, Thomas -- Dipl.-Inform. Thomas Klute kl...@ingenit.com Geschäftsführer / CEO -- ingenit GmbH & Co.

[ovirt-users] Stable Next Generation Node Image for 4.0.2?
Dear oVirt community, what is the correct way to set up a next generation node of the latest stable version (4.0.2)? Take the image from http://resources.ovirt.org/pub/ovirt-4.0/iso/ovirt-node-ng-installer/ ? Seems to be 4.0.0 and then update? Or take the image from http://resources.ovirt.org/pub/ovirt-4.0-snapshot/iso/ Seems to be 4.0.2 but nightly and thus unstable? Thanks for the clarification, best regards, Thomas ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
