Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?

This is a multi-part message in MIME format. --------------27CA2B1123847DBF1F81EC89 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable 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=3D2 ... 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?

FreeIPA authentication broken
by Kristian Petersen 24 Apr '18

24 Apr '18

Hey everyone, I had FreeIPA authentication set up on my oVirt instance and it was working great. Then something happened that disconnected my NFS storage and caused a problem with my hosted-engine. Once I got it back up and running again, my FreeIPA authentication was sill a choice for authentication, but it always rejects my password even though it is correct. I have tried running the setup again to no avail. Nothing shows up in the httpd error log when the login fails. The engine.log from ovirt-engine in /var/log shows the following upon attempting to authenticate with a user from freeIPA: 2018-04-23 08:08:24,384-06 WARN [org.ovirt.engineextensions.aaa.ldap.Framework] (default task-34) [] Ignoring records from pool: 'authz' 2018-04-23 08:08:24,384-06 ERROR [org.ovirt.engine.core.sso.servlets.InteractiveAuthServlet] (default task-34) [] Cannot authenticate user 'nesretep@IPA' connecting from 'UNKNOWN': The username or password is incorrect. I'm not sure why 'authz' is being ignored but it is certainly why IPA authentication isn't working as 'username@authz' is how IPA logins show up in oVirt when they do work. Any ideas where to look next? -- Kristian Petersen System Administrator BYU Dept. of Chemistry and Biochemistry

Hosted Engine won't start, how to debug?
by Thomas Klute 23 Apr '18

23 Apr '18

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.

Cluster Processor Change
by Clint Boggio 23 Apr '18

23 Apr '18

Forgive me if this is a duplicate, as I had spam filter problems previously when I sent this inquiry. Environment Rundown: OVirt 4.2 6 CentOS 7.4 Compute Nodes Intel Xeon 1 CentOS 7.4 Dedicated Engine Node Intel Xeon 1 Datacenter 1 Storage Domain 1 Cluster 10Gig-E iSCSI Storage 10Gig-E NFS Export Domain 20 VM’s of various OS’s and uses The current cluster is using the Nehalem architecture. I’ve got the deploy two new VMs that the current system will not allow me to configure with the Nehalem based cluster, so I’ve got to bump up the architecture of the cluster to accommodate them. Before i shut down all the current VMs to upgrade the cluster, I have some questions about the effect this is going to have on the environment. 1. Will all of the current VM’s use the legacy processor architecture or will I have to change them ? 2. Can I elevate the cluster processor functionality higher than the underlying hardware architecture ? 3. In regards to the new cluster processor, will all of the processor architectures below the one I choose be an option for the existing and future VMs ? I apologize for the long post and I hope that I haven’t left out any vital information.
