Hi all, I have an Ovirt 4.2.8 cluster. Nodes are 4.2 ovirt nodes and the volumes (5) attached to nodes by FC. 2 weeks ago i made a small vm (centos 7 based) for me to test (name A). After the test i dropped a vm. Next day a made an another vm (named B) to the developes and tired to add a new disk to the vm (B). Than a original volume group (vg) of the vm (B) missed and i got back the yesterday dropped vm`s (A) vg! I tired to restart a vm, but the vm never started again. I dropped this vm (B) too, and tired to add a new disk an older running vm (C) too, but a volume group changed to that vm`s vg what i dropped before (B). I checked this „error” and i got it ,then i delete or move disks from the end of the FC volume. Have sombody ever seen error like this? Thanks, csaba Ps: in this cluster a managed 120 productive vm, so….

Hi all, If anyone uses latest pycurl 7.43 provided by pip or ansible tower/awx, any ovirtsdk4 calling will issue with the log: The full traceback is: WARNING: The below traceback may *not* be related to the actual failure.

oVirt 4.2.8 CPU Compatibility
by Stefano Danzi 24 Jan '19

24 Jan '19

Hello! I'm running oVirt 4.2.7.5-1.el7 on 3 hosts cluster. Cluster CPU Type is "AMD Opteron G3". On default cluster I can see the warning: "Warning: The CPU type 'AMD Opteron G3' will not be supported in the next minor version update'" Is it still supported in version 4.2.8? I can't see references in documentation or changelog.

Q: Is it safe to execute on node "saslpasswd2 -a libvirt username" ?
by Andrei Verovski 23 Jan '19

23 Jan '19

Hi ! Is it safe to execute on oVirt node this command ? saslpasswd2 -a libvirt username Its a production environment, screwing up anything is not an option. I have no idea how VDSM interacts with libvirt, so not sure about this. Thanks in advance Andrei

Host non-responsive after yum update CentOS7/Ovirt3.6
by jaherring＠usa.net 23 Jan '19

23 Jan '19

Hi, I working on a CentOS7 based Ovirt 3.6 system (ovirt-engine/db on one machine, two separate ovirt vm hosts) which has been running fine but mostly ignored for 2-3 of years. Recently it was decided to update the OS as it was far behind on security updates, so one host was put into maintenance mode, yum update'd, rebooted, and then it was attempted to take out of maintenance mode but it's "non-responsive" now. If I look in /var/log/ovirt-engine/engine.log on the engine machine I see for this host (vmserver2): "ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesVDSCommand] (DefaultQuartzScheduler_Worker-36) [2bc0978d] Command 'GetCapabilitiesVDSCommand(HostName = vmserver2, VdsIdAndVdsVDSCommandParametersBase:{runAsync='true', hostId='6725086f-42c0-40eb-91f1-0f2411ea9432', vds='Host[vmserver2,6725086f-42c0-40eb-91f1-0f2411ea9432]'})' execution failed: org.ovirt.vdsm.jsonrpc.client.ClientConnectionException: Connection failed" and thereafter more errors. This keep repeating in the log. In the Ovirt GUI I see multiple occurrences of log entries for the problem host: "vmserver2...command failed: Vds timeout occurred" "vmserver2...command failed: Heartbeat exceeded" "vmserver2...command failed: internal error: Unknown CPU model Broadwell-noTSX-IBRS" Firewall rules look identical to the host which is working normally but has not been updated. Any thoughts about how to fix or further troubleshoot this?

Migrating Hosted Engine environment from untagged to LACP bonded interfaces with tagged ovirtmgmt network
by Bernhard Dick 23 Jan '19

23 Jan '19

Hi, I have an oVirt 4.2 environment running with the engine in hosted engine state. We are now going to change our whole setup migrating to redundancy on switch side and using a different VLAN for the ovirt management traffic. Currently all host and management-traffic is running untagged on one network interface on all of our hosts and we want to change this to be VLAN-tagged inside LACP-Bonds (each bond containing two network interfaces) on all hosts. While changing the configuration for the VM networks should be straight forward as I can shutdown all VMs during the migration I'm asking how to handle this for the hosted engine VM and configuration. Is there any information how to do such a change? Regards Bernhard

Adding host with local-storage VMs configured
by Callum Smith 23 Jan '19

23 Jan '19

Dear All, We’re in a world where we had to recover from outage by installing a clean hosted engine and importing VMs from storage. We do, however, have a host that is configured for local-storage and has a VM running on it. What is the best way to re-introduce this host to a new hosted-engine with minimal outage of the VM on that host.
