by Thomas Letherby 16 Sep '18

16 Sep '18

Hello all, I've been looking around but I've not found anything definitive on whether Ovirt can do NFS Multipathing, and if so how? Does anyone have any good how tos or configuration guides? Thanks, Thomas

Failed to synchronize networks of Provider ovirt-provider-ovn
by Kapetanakis Giannis 14 Sep '18

14 Sep '18

Hi, After upgrading to 4.2.1 I have problems with ovn provider. I'm getting "Failed to synchronize networks of Provider ovirt-provider-ovn." I use custom SSL certificate in apache and I guess this is the reason. I've tried to update ovirt-provider-ovn.conf with [OVIRT] #ovirt-ca-file=/etc/pki/ovirt-engine/ca.pem ovirt-ca-file=/etc/pki/ovirt-engine/apache-ca.pem but still no go Any tips on this? thanks G

self-hosted engine lost password
by Rob Epping 04 Sep '18

04 Sep '18

Hello list, I'm trying to update our ovirt self-hosted engine to the latest version using the docs at https://www.ovirt.org/documentation/upgrade-guide/chap-Updates_between_ Minor_Releases/#updating-the-ovirt-self-hosted-engine-and-underlying- virtualization-hosts For this I need to logon to the engine VM, but none of the passwords we used seems to work. I can not seem to find information on how te reset passwords of the hosted engine, so I'm stuck. Am I doing something wrong or is access to the self-hosted engine required. When access is required, is there a way to reset the password? THNX && GRTNX, RobJE

Wrong network threshold limit warnings on 4.2.5
by Florian Schmid 04 Sep '18

04 Sep '18

Good morning, since we have upgraded to version 4.2.5, we get a lot of warnings about network interface exceeded defined threshold limits. For example: Aug 31, 2018, 7:54:05 AM Host xxx has network interface which exceeded the defined threshold [95%] (enp9s0.80: transmit rate[100%], receive rate [12%]) This is a 10 Gbit interface and on our monitoring software, which is getting network statistics every 10s, the bandwidth of TX was 150 Mbit maximum at this time, so far away from being 100%. Could it be, that the engine detected the wrong interface speed or there is a calculation error? In the engine for this host, I have 10000 Mbps for all interfaces. I have checked now all those warnings on our different hosts and they happen every time, we go over 100 Mbit and this is for sure quite often... Can I maybe disable these warnings, because we have it anyway in our monitoring software? If you need any logs, please ask. BR Florian Schmid

Bricks do not appear in oVirt Manager UI under Hosts unless manually created on nodes.
by payden.pringle+ovirtlist＠gmail.com 03 Sep '18

03 Sep '18

I have a CentOS 7.5 system running the oVirt-Engine package as the manager for three oVirt Nodes (version 4.2). Two of the nodes have a 200GB disk and one has a 2GB disk. I am attempting to create a Gluster Volume that replicates between the two 200GB disks with the 2GB as Arbiter. When I create the bricks by going to Hosts > host1 > Storage Devices > Create Brick (with the 200GB device selected), it succeeds, but no bricks appear under the Bricks tab for the Host. Doing the same for host2 and host3 results in the same problem. If I run the following command on a host `gluster volume create test-volume replica 3 arbiter 1 192.168.5.{50,60,40}:/gluster-bricks/200GBbrick/test`, it creates the volume correctly and the bricks then appear as they should. However, then these Bricks are labeled as "Down" and when I go to Storage > Volumes, I get this error: ``` Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'a' of null Please have your administrator check the UI logs ``` The Volume is also shown as "Down". SELinux is enabled on my CentOS 7.5 system. I'm not really sure what the correct method is to create bricks then a Volume in Gluster through the oVirt Management UI, but I've followed the guides and this is where it has got me.

oVirt Node 4.2.3.1. to 4.2.5 upgrade trouble, log attached
by Matt Simonsen 03 Sep '18

03 Sep '18

Hello all, I've emailed about similar trouble with an oVirt Node upgrade using the ISO install. I've attached the /tmp/imgbased.log file in hopes it will help give a clue as to why the trouble. Since these use NFS storage I can rebuild, but would like to know, ideally, what caused the upgrade to break. Truthfully following the install, I don't think I have done *that* much to these systems, so I'm not sure what would have caused the problem. I have done several successful upgrades in the past and most of my standalone systems have been working great. I've been really happy with oVirt, so kudos to the team. Thanks for any help, Matt

Possible vdsmd issues - " WARN Worker blocked"
by Johnson, Tim 31 Aug '18

31 Aug '18

Hi all, We have had a bit of a strange issue with the starting of the self-hosted engine due to the vdsm and ovirt-ha processes having errors and not able to be started. Running Ovirt version 4.2 with Gluster mounts (not hyper converged) gluster 3.12.13 replicated volumes with arbiter brick. The mounts for the storage are mounted on all the Ovirt hosts and able to read/touch files on the mounts. Unfortunately we can not pin a specific timeframe when this started happening. Meaning we don’t know if it started after a specific update or any other event.

Hosted Engine, Node, Local Storage, All in One

Can anyone tell me if this can be done? I have read various articles and I'm not sure. http://blog.domb.net/?p=2141 https://www.ovirt.org/develop/release-management/features/integration/allin…<http://blog.domb.net/?p=2141> According to my google search results the ovirt article date is within the last year approximately but I says deprecated after version 3.6 yet the 1st article makes it seem it can be done. I know this goes against standard practice but there is a reason I'm trying to do it. If it is possible, can anyone point me to a guide or give me an overview of the steps needed? Thank you for your help!

ovirt-engine-extension-aaa-ldap-setup credentials invalid
by Douglas Duckworth 30 Aug '18

30 Aug '18

Hi I am not able to finish ovirt-engine-extension-aaa-ldap-setup due to the error "credentials invalid." My password's correct. Our directory server's OpenLDAP standard schema. Our accounts are under OU=People. We are binding with a service account that has access to the entire DN. Any way to discern more information from attached logs? Thanks, Douglas Duckworth, MSc, LFCS HPC System Administrator Scientific Computing Unit Weill Cornell Medicine 1300 York Avenue New York, NY 10065 E: doug(a)med.cornell.edu O: 212-746-6305 F: 212-746-8690

Multiple CephFS Monitors cause issues with oVirt
by Stack Korora 30 Aug '18

30 Aug '18

Greetings, My setup is a complete Red Hat install. Manager OS: RHEL 7.5 Hypervisors OS: RHEL 7.5 Running Red Hat CephFS (with their Ceph repos on all of the systems) with Red Hat Virtualization (aka oVirt). Everything is fully patched and updated as of yesterday morning. Yes, I have valid Red Hat support but I figured this was an odd enough problem that the community (and the Red-Hat-ers who hang out on this list) might have a better idea of where to start. (Although I might open a ticket anyway just because that is what support is for, right? :) Quick background: Your /etc/fstab when you mount a nfs should probably look something like this: <your.nfs.ip.addr>:/path/ /mount/point nfs <various options> 0 0 Just one IP is needed. Since part of the redundancy for Ceph is in the monitors, to mount CephFS the fstab should look something like this: <your.ceph.ip.addr1>,<your.ceph.ip.addr2>,<your.ceph.ip.addrX>:/path/ /mount/point ceph <various options> 0 0 Both the Ceph community and Red Hat recommend the comma separator for mounting multiple CephFS monitor nodes. (See section 4.2 point 3) https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html/c… Now to oVirt/RHV. When I mount my Data Domain path as a Posix file system with a path of "<your.ceph.ip.addr1>:/path/" it works splendidly well (especially after the last Red Hat kernel update!). I've done a bunch of stuff to it and it seems to work every time. However, I don't have the redundancy of multiple Ceph Monitors. When I mount my Data Domain path as a Posix file system with a path of "<your.ceph.ip.addr1>,<your.ceph.ip.addr2>,<your.ceph.ip.addrX>:/path/" most things seem to work. But I noticed a higher rate of failures. The only failure that I can trigger 100% of the time though is to mount a second data import domain and attempt to copy a vm disk from the import into the CephFS Data domain. Then I get an error like this: would VDSM ovirt01 command HSMGetAllTasksStatusesVDS failed: low level Image copy failed: (u'Destination volume 7c1bb510-9f35-4456-8d51-0955f788ac3e error: ParamsList: sep , in /rhev/data-center/mnt/<your.ceph.ip.addr1>,<your.ceph.ip.addr2>,<your.ceph.ip.addr3>:_ovirt_data/70fb34ad-e66d-43e6-8412-5e020baa34df/images/23991a68-0c43-433f-b1f9-48b1533da54a',) Uh, oh. It seems that the commas in the mount path are causing the problems. So I went looking through the logs for "sep , in" and found a bunch more hits which makes me think that this is actually the problem message. I've switched back to just one IP address for the time being but I obviously want the Ceph redundancy back. While running on just one IP, the vm disk that refused to copy before had no problem copying. The _only_ change I made was dropping two of the three IP's from the Data Domain path option. Is this a bug, or did I do something wrong? Does anyone have a suggestion for me to try? Thank you! ~Stack~

Thanks for sharing I may want to do that Though first I want to understand how the emails are arriving. I stooped ovirt-engine-notifier.service and postfix.service on all hosts and the hosted engine. So how are the email being delivered? They are not running senmail so I don't understand what daemon's sending these messages.

Not for me. After restarting the engine,it doesn't matter if I restart the Hypervisors, I only get the "protocol=gluster" when I restart the VMs... migration is not enough.

Weird Memory Leak Issue
by Cole Johnson 29 Aug '18

29 Aug '18

Hello, I have a hyperconverged, self hosted ovirt cluster with three hosts, running 4 VM's. The hosts are running the latest ovirt node. The VM's are Linux, Windows server 2016, and Windows Server 2008r2. The problem is with any host running the 2008r2 VM will run out of memory after 8-10 hours, causing any VM on the host to be paused, and making to host all but unresponsive. This problem seems to only exist with this specific VM. None of the other running VM's have this problem. I can resolve the problem by migrating the VM to a different host, then putting the host into maintenance mode, the activating it back. The leak appears to be in glusterfsd. Is there anything I can do to permanently fix this?

Next Gluster Updates?

I had a bug request in Bugzilla for Gluster being killed due to a memory leak. The Gluster People say it is fixed in gluster-3.12.13 When will Ovirt have this update? I am getting tired of having to restart my hypervisors every week or so...

Guide for setting up GlusterFS geo-replication?
by Jayme 29 Aug '18

29 Aug '18

Is there an updated guide for setting up GlusterFS geo-replication? What I am interested in is having another oVirt setup on a separate server with glusterFS volume replicated to it. If my primary cluster went down I would be able to start important VMs on the secondary oVirt build until I'm able to repair the main cluster. In oVirt 4.2.5 clicking geo-replication > new in the volume GUI produces no results. Nothing happens when I click it (using multiple browsers). And under storage domains clicking remote data-sync -> setup produces a popup but just has a loading icon in the middle and never completes loading. Why are neither of these two features working for me?

Turn Off Email Alerts
by Douglas Duckworth 28 Aug '18

28 Aug '18

Hi How do I turn off hosted engine alerts? We are in a testing phase so these are not needed. I have disabled postfix on all hosts as well as stopped the ovirt notification daemon on the hosted engine. I kept it running while putting /dev/null in /usr/share/ovirt-engine/services/ovirt-engine-notifier/ovirt-engine-notifier.conf for mail server. Yet I still get alerts for every thing done such as putting hosts in maintenance mode. Very confusing.

mask or disabled lldpad service
by Klaas Demter 28 Aug '18

28 Aug '18

Hi, I have a QLogic Corp. QLogic 2x1GE+2x10GE QL41162HMRJ CNA network card. This network card comes with it's own lldp implementation inside their management firmware. Running two lldp agents seems to create several issues (http://lists.us.dell.com/pipermail/linux-poweredge/2018-July/051860.html) The QLogic engineers said I need to disable lldpad in the operating system. This leads me here, what is lldp actually used for within ovirt? If it is actually needed how could I deal with a card that does not support lldpad but rather has it's own implementation? Greetings Klaas

VDO + HCI = failed reboots
by Donny Davis 28 Aug '18

28 Aug '18

I just spun up the latest and greatest ovirt has to offer, and I am building out an HCI cluster. The deployment went wonderfully. I had dns setup for everything, and it just worked. Great job team! I just wanted to add in something i noticed after rebooting the nodes. The gluster service, and volumes would not come back up after rebooting. I found that there needs to be an entry in the fstab for the gluster logical volumes to tell them to start the vdo service. So without this, the node will fail to boot if you are using vdo. inode64,noatime,nodiratime,discard,x-systemd.requires=vdo.service the defaults are this inode64,noatime,nodiratime Hopefully it helps someone else :) Cheers

Migrating to HCI
by Vincent Royer 28 Aug '18

28 Aug '18

I have 2 hosts using NFS storage I want to migrate to HCI and add a third host. Have added the 10Gbe cards and drives to the 3 target hosts and setup a separate physical network for storage. Can I: - deploy a single-node HCI to host 3 - export the VMs to an NFS export domain - Import the VMs to the HCI node - wipe the first 2 hosts and re-deploy them to the HCI DC Is there a guide for this? or should I just export the VMs, blow away all the nodes, and deploy as a 3-node HCI using the wizards? I'm hoping to minimize downtime of the VMs to under one day. *Vince*

One Windows VM is not responding
by Jonathan Baecker 27 Aug '18

27 Aug '18

Hello Everybody! We have here 13 VMs running under ovirt 4.2.4. Two of them are Windows Server 2016. On one runs a AD, DNS and one application. On the second one runs an SQL Server and also an application. This second one have the problem, that periodical it goes in a state where I get in ovirt the message: *not responding * Beside this the VM is running normal. I can connect it over Remote Desktop. But I can not connect it with ovirt/noVNC, the button is gray out. In a weekly cycle it runs a backup script, maybe this brings some problems, but I really don't know how to debug this. It can be that the VM runs for 3 weeks normal, and then it goes in this state, so I can not really say when this is happen. Also the fact that the other Windows Server VM runs normal, wonders me. Do you have experienced this problem, or do you know how I found out the issue? Best Regards! Jonathan

Re: External ceph storage

No, The only way you have is to configure cinder to manage ceph pool or in alternative you have to deploy an iscsi gateway, no other ways are available at the moment. So you can't use rbd directly.

Unknown CPU model Broadwell-IBRS-SSBD

Hi, I've just installed hosted-engine. It proceeds to near the end of the Ansible script, then pauses at: "TASK [Check engine VM health]" then eventually errors: "Engine VM is not running, please check vdsm logs. The VDSM logs have error: "libvirtError: internal error: Unknown CPU model Broadwell-IBRS-SSBD" Also, in the oVirt Node webui, the HostedEngine VM is created, but not started. If I press Run, the following error is shown: VM START action failed error: Failed to start domain HostedEngine error: internal error: Unknown CPU model Broadwell-IBRS-SSBD I notice a Trello card was created to add similar Skylake & EPYC CPUs, but not Broadwell: https://trello.com/c/5nGTgQ9P/89-new-ibrs-and-ssbd-cpu-types# Does the Broadwell-IBRS-SSBD CPU need to be added to this supported types list? Many thanks.

Console to HostedEngine
by Daniel Menzel 24 Aug '18

24 Aug '18

Hi at all, we cannot access our hosted engine anymore. It started with and overfull /var due to a growing database. We access the engine via SSH and tried to fix that - but somehow we seem to have produced another problem on the SSH server itself. So unfortunately we can not login anymore. We then tried to access it via its host and a "hosted-engine --console" but ran into an internal error: cannot find character device <null> which I know from KVM. With other VMs I could follow the RedHat's advice to add a console (https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/ht…) but although I edited the hosted engine's profile those changes weren't applied - and after an engine restart even deleted again. That kind of makes sense to me, but limits my options. So my question is: Is there any idea how can I access the the console with my current limitations to fix the SSH server's problems and then hopefully fix everything? Regards Daniel

Hi Dominik Yes, the network-script was created by our Ansible role that deploys CentOS hosts. It pulls the IP from DNS then templates the script and copies to host. I will try this oVirt step then see if it works!

Upgrading librbd1 and librados2 for oVirt 4.2.x
by andreas.elvers+ovirtforum＠solutions.work 24 Aug '18

24 Aug '18

Hallo Group ! I am in need of upgrading librbd1 and librados2 for a oVirt 4.2.x cluster. The cluster was installed via node ng. Taking the repository for Ceph Mimic or Luminous will end in a dependency problem because liburcu-cds.so.1 is already installed as a more recent version provided by the oVirt repository. A hint on how to get a more recent versions of the above libraries would be very much appreciated. Thanks, - Andreas

HA VMs not starting automatically on another host after host crash.
by Eduardo Mayoral 24 Aug '18

24 Aug '18

Hi, Recently I have had 2 oVirt hosts (oVirt 4.2, CentOS 7.5) crash unexpectedly (not at the same time). Both seem hardware related. In both cases oVirt did detect the host as non responsive, did a fence on the hosts and set the VMs which were running on the host at the time as "Down". So far, so good. The hosts were on 2 different clusters. Both had Migration policy / resilience policy set to "migrate Virtual Machines". The VMs are not configured as "Highly available", but my understanding is that with that resiliency policy, this makes no difference. My (probably wrong) expectation, is that oVirt should have attempted to start the VMs in another host. It did not. A colleague started the VMs manually and they started with no further issues. So. How should I configure oVirt to try to start the VMs on another host when the physical host they are running in crashes? Thanks in advance! -- Eduardo Mayoral.

VM has been paused due to unknown storage error. - Only on NFS / EMC
by jeanbaptiste＠nfrance.com 24 Aug '18

24 Aug '18

Hello, I'm facing a strange issue on my OVirt Dev pool. Indeed, when I create high disk load a VM (kickstart installation or iozone test for example) , VM is paused due to storage I/O error. Problem is 100% reproducible, and is located only on NFS (v3 and v4) on my EMC VNXe3200 NAS's (I have a 10TB and a 20TB NAS) I have done test (simple iozone -a) with VM 1 vCPU / 2GB RAM and 2 disk (1*20GB + 1*10GB). Both VMs disk are placed into the same SAN / NAS for each test.

Update disk alias by using ovirtsdk4
by branimirp＠gmail.com 24 Aug '18

24 Aug '18

Hello list! I have been trying to rename a disk alias that defaults to "some_template_name-Disk1" to something more logical by using ovirtsdk4 (in my example to "vm2_disk_0"). On the list itself, I saw a couple of examples for older version of SDK. Basically, I am trying to create a VM and then update its properties, notably "alias" attribute that can be found in types.Disk. The first portion of the code works well (vm provisioning), but second one (alias update) does not, causing the TypeError exception. Obviously, I am doing something wrong here. I have spent most of the time trying to figure out how to actually do this. I would kindly ask for some hint. Thank you in advance! Regards, Branimir ******************************* # create a vm vms_service = connection.system_service().vms_service() vms_service.add( types.Vm( # --- vm name name='vm2', # --- vCpus cpu=types.Cpu( topology=types.CpuTopology(cores=2, sockets=1) ), # --- memory memory = 512*1024*1024, # -- oVirt cluster cluster = types.Cluster( name='cluster_1', ), # -- template to use template = types.Template( name='centos7-tmplt-compute-node-v1'), # -- boot device os = types.OperatingSystem(boot=types.Boot(devices=[types.BootDevice.HD])), ), ) # update the vm in terms of disk name vm = vms_service.list(search='name=vm2')[0] vm_service = vms_service.vm_service(vm.id) updated_vm = vm_service.update( types.Vm( disk_attachment = types.Disk(alias='vm2_disk_0') ) )

Upgrading librbd1 and librados2 for oVirt 4.2.x
by Andreas Elvers 23 Aug '18

23 Aug '18

Hello, I am in need of upgrading librbd1 and librados2 for a oVirt 4.2.x cluster. The cluster was installed via node ng. Taking the repository for Ceph Mimic or Luminous will end with a dependency problem because liburcu-cds.so.1 is already installed as a more recent version. A hint on how to get a more recent versions of the above libraries would be very much appreciated. Thanks, - Andreas

Data Center non-responsive, storage not loading, and psql errors after importing an ova
by josh＠nightscapetech.com 23 Aug '18

23 Aug '18

I posted about this a few months ago on Reddit when it happened the first time, and I have now repeated it on two more separate installations. I have a simple oVirt 4.2 hosted-engine setup, two hosts, with a qnap NAS as the shared NFS storage. I copied an ova file (exported from vmware) to the NFS storage. I then imported it by logging into the engine gui, going to "Virtual machines", selecting the host/file path/datacenter/etc, and starting the import. Once I started the import, I get an alert that it failed almost immediately, followed by a notice that the data center is in a non-responsive state. Clicking on the "storage" tab under Data Center, or going to the "Storage Domain" page directly yields the three ". . ." loading animation, which never ends. I can still see the storage mounts on the hosts, and I can move files to and from them. the engine.log file on the hosted-engine VM contains a lot of the following lines: Caused by: org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [select * from getstorage_domains_list_by_imageid (?)]; ERROR: integer out of range Where: PL/pgSQL function getstorage_domains_list_by_imageid(uuid) line 3 at RETURN QUERY; nested exception is org.postgresql.util.PSQLException: ER ROR: integer out of range Where: PL/pgSQL function getstorage_domains_list_by_imageid(uuid) line 3 at RETURN QUERY at org.springframework.jdbc.support.SQLStateSQLExceptionTranslator.doTranslate(SQLStateSQLExceptionTranslator.java:102) [spring-jdbc.jar:4.3. 9.RELEASE] What I have tried: Restarting the hosted-engine service Restarting nfs and vdsm services Rebooting the hosted-engine Rebooting both hosts Entering an exiting maintenance mode (one host never came out of maintenance, and refuses to with the error " General command validation failure ") Any idea what might have happened? And what should I have done to try to rectify it? Entering maintenance mode and restarting services seems to have made things much worse.
