Shameless networking question
by Peter Harman 23 May '18

23 May '18

Ovirt Community, First off: thank you - these emails have helped me to get Ovirt running. I barely know what I am doing but learning quickly. I am trying to do a network separation and confusing myself. I have two physical networks (10.10.x.x/16 and 192.168.1.x/24) my ovirt management is bridged on 10.10.x.x. My (currently single) Hosts have at least one physical NIC connecting to each network. I am trying to get to the point there the VMs are on the 192.168.1.x network and the 10.10.x.x network. The goal is to join the VMs to a AD domain on 192.168.1.x but keep access as limited as possible to the 10.10.x.x network. I've been on a googlethon over the past few days and still don't understand the best practice - or even a working practice - to accomplish this goal.

How to delete leftover of a failed live storage migration disk
by Gianluca Cecchi 23 May '18

23 May '18

Hello, I had an error during live storage migration of a disk. The destination image was created but the process was not completed, because of a bug in the original version of sw. Then I updated sw but if I try to run again the move of the same disk to the same destination storage domain I get VDSM command HSMGetAllTasksStatusesVDS failed: Cannot create Logical Volume: ('679c0725-75fb-4af7-bff1-7c447c5d789c', 'd2a89b5e-7d62-4695-96d8-b762ce52b379') On destination storage domain, that is empty, from web admin gui I see only the 2 OVF_STORE disks. From OS point of view using lvs I see the leftover LV that oVirt complains not able to create (I suppose because already existent due to the former error) # lvs 679c0725-75fb-4af7-bff1-7c447c5d789c/d2a89b5e-7d62-4695-96d8-b762ce52b379 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert d2a89b5e-7d62-4695-96d8-b762ce52b379 679c0725-75fb-4af7-bff1-7c447c5d789c -wi------- 55.00g I know that I should use the "vdsClient -s 0 deleteVolume " command from the SPM host. the syntax should be # vdsClient -s 0 deleteVolume --help Error using command: list index out of range deleteVolume <sdUUID> <spUUID> <imgUUID> <volUUID>,...,<volUUID> <postZero> [<force>] Deletes an volume if its a leaf. Else returns error I have difficulties to do the exact mapping of the various elements. Is it right what below? sdUUID --> VG name spUUID I can retrieve using: # vdsClient -s 0 getStorageDomainInfo 679c0725-75fb-4af7-bff1-7c447c5d789c uuid = 679c0725-75fb-4af7-bff1-7c447c5d789c type = ISCSI vguuid = nkoZA2-nQOu-oeXX-Phpa-moqh-FWuR-AFAh4B metadataDevice = 36589cfc0000006dd999f5618bf759d3f state = OK version = 4 role = Master vgMetadataDevice = 36589cfc0000006dd999f5618bf759d3f class = Data pool = ['5af30d59-004c-02f2-01c9-0000000000b8'] name = ISCSI_400G so spUUID is the pool --> 5af30d59-004c-02f2-01c9-0000000000b8 in my case ? for imgUUID I don't know a command to retrieve. in my case the target storage domain (ISCSI_400G) in this moment is the master one and I can see it under /rhev/data-center/mnt/blockSD/ and so I find # ll /rhev/data-center/mnt/blockSD/679c0725-75fb-4af7-bff1-7c447c5d789c/images/ total 4 drwxr-xr-x. 2 vdsm kvm 4096 May 10 15:39 530b3e7f-4ce4-4051-9cac-1112f5f9e8b5 So it seems to me in my case imgUUID is 530b3e7f-4ce4-4051-9cac-1112f5f9e8b5 But even if it is right in my particular case, how can I get in general? volUUID ? Is it the LV name corresponding, so in my case d2a89b5e-7d62-4695-96d8-b762ce52b379 ? The result of the vdsCLient command should be the removal of LV also? Thanks in advance for any insight or link to details... Gianluca

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
