info about reinstall dead node
by Gianluca Cecchi 23 May '18

23 May '18

Hello, I have an host dead in a 4.1.9 environment (broken raid controller compromised both internal disks, don't ask me how it could happen...). I have replaced controller/disks and reinstalled ng-node on the same hw with the same parameters and same version (but ovirtmgmt bridge not present yet, only a bond0 that has to become backed up by the ovirtmgmt bridge when installed). In web admin gui it had been set as not responsive when failed. Now I cannot reinstall it as new. If I try to put it into maintenance it is correctly rebooted but then it remains non responsive. I think I have to "force remove" in some way the previous instance of this node, but the option is greyed out... How can I clean the node and then try to install as new again? Thanks, Gianluca

First host within Self-Hosted engine stays in non-responsive state
by 03ce007＠gmail.com 23 May '18

23 May '18

I am trying to setup self-hosted-engine (4.2) on a single machine running centos 7.4. I ran hosted-engine deploy script and it ran all the way through but failed on last task (at "Wait for the local bootstrap VM to be down at engine eyes") while creating the local engine VM. However, the --vm-status shows the engine status as up and is in good health, but I cannot interact with host installed on engine VM. The host within engine VM shows it is in non-responsive state, not clear why and what caused it. I can ssh into the local engine VM and the engine.log has below entries - 2018-05-17 11:03:57,739+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.VmDevicesMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-78) [6768004b] Exception:: org.springframework.dao.DataIntegrityViolationException: CallableStatementCallback; SQL [{call insertvmdevice(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}]; ERROR: insert or update on table "vm_device" violates foreign key constraint "fk_vm_device_vm_static" Detail: Key (vm_id)=(114581bb-7fef-4b08-8e3c-85dd5a9e680b) is not present in table "vm_static". ... ... ... 2018-05-17 11:03:59,957+01 ERROR [org.ovirt.engine.core.bll.pm.FenceProxyLocator] (EE-ManagedThreadFactory-engineScheduled-Thread-44) [2bf8b18f] Can not run fence action on host 'ovirt', no suitable proxy host was found. ... ... ... 2018-05-17 11:20:00,093+01 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (EE-ManagedThreadFactory-engine-Thread-2) [1a833057] Exception during connection ... ... ... 2018-05-17 11:20:00,386+01 ERROR [org.ovirt.engine.core.vdsbroker.HostDevListByCapsVDSCommand] (EE-ManagedThreadFactory-engine-Thread-2) [1a833057] Command 'HostDevListByCapsVDSCommand(HostName = ovirt, VdsIdAndVdsVDSCommandParametersBase:{hostId='1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99', vds='Host[ovirt,1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99]'})' execution failed: java.net.UnknownHostException: ovirt: Name or service not known ... ... ... 2018-05-17 11:20:03,287+01 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Exception during connection 2018-05-17 11:20:03,292+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Unable to RefreshCapabilities: UnknownHostException: ovirt 2018-05-17 11:20:03,294+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Command 'org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand' return value 'org.ovirt.engine.core.vdsbroker.vdsbroker.VDSInfoReturn@46e3da89' 2018-05-17 11:20:03,294+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] HostName = ovirt 2018-05-17 11:20:03,297+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = ovirt, VdsIdAndVdsVDSCommandParametersBase:{hostId='1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99', vds='Host[ovirt,1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99]'})' execution failed: java.net.UnknownHostException: ovirt 2018-05-17 11:20:03,316+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-15) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM ovirt command GetCapabilitiesAsyncVDS failed: Connection issue ovirt 2018-05-17 11:20:03,317+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-15) [] Unable to RefreshCapabilities: VDSNetworkException: VDSGenericException: VDSNetworkException: Connection issue ovirt ... ... ... and then above 5 ERROR messages are keep getting repeated.

update from 4.1.9 to 4.2.3 and OVN doubt
by Gianluca Cecchi 23 May '18

23 May '18

Hello, at beginning of 2017 I configured OVN in my oVirt 4.1.0 setup, with the previosulsy described notes, I think the ones here: http://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ At that time OVN was not directly integrated in oVirt setup. Then I applied the updates in minor releases and coming at 4.1.9 level in late January this year. Now I plan to update to 4.2.3. I have doubts related to OVN setup. Will the new 4.2.3 OVN setup conflict with my current 4.1.x setup? WHat do I have to answer in setup related questions and prompt? In fact now, after enabling 4.2 repo and updating the setup itself, during the procedure (that I Canceled right now) I receive these questions: # engine-setup . . .

oVirt: engine backup
by femi adegoke 23 May '18

23 May '18

Reading this: https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restori… It says the node must be in maintenance mode. I was having a discussion on IRC & they were using this (see link) to backup, it makes no mention of maint mode https://scottlinux.com/2015/08/20/create-daily-rhevm-backups/ https://access.redhat.com/solutions/797463 Question: must the node be in maint mode before engine is backed up?

Planned restart of production services
by Evgheni Dereveanchin 23 May '18

23 May '18

Hi everyone, I will be restarting several production systems within the following hour to apply security updates. The following services may be unreachable for some period of time: - www.ovirt.org - project website - resources.ovirt.org - package repositories - gerrit.ovirt.org - code review - jenkins.ovirt.org - CI master It will not be possible to submit/review patches, clone repositories or run CI jobs during this period. Package repositories and the website will also be unreachable for a short period of time. I will announce you once the maintenance is complete. -- Regards, Evgheni Dereveanchin

Nginx proxy for Ovirt
by Aziz 22 May '18

22 May '18

Hi All, I'm trying to setup nginx as a reverse proxy in order to access ovirt remotely without having to add the fqdn in SSO_ALTERNATE_ENGINE_FQDNS , the idea is that nginx will handle the fqdn translation from my external FQDN (external.fqdn.net ) to ovirt's fqdn (lab.vdi.net) Is there a way to achieve scenario ? Thank you in advance ? Aziz

Hello, We have an old Windows XP VM, that requires access to a physical serial port for our telephone system. We have this working in VMWare, however, I'm not entirely sure how we would set this up in oVirt? Can someone help please? Kind Regards, Joshua Blake

Use local ansible to talk to engineVM and other vm
by 03ce007＠gmail.com 22 May '18

22 May '18

I have a self-hosted-engine (4.2) running on a centos 7.4 server. I have downloaded ovirt ansible roles from ansible-galaxy and can run them from the server where the engineVM is running and able to deploy new vms, clusters, dc, etc. I have seen the use of ovirt4.py file to target and group hosts which you can target for specific plays. However, the box where self-hosted-engine is running is a physical server but I am looking to run ansible from my local machine instead to manage vms running on engineVM. Is there a way to achieve this? Thank you in advance.
