Logical interface naming issues
by Tom Edwards 09 May '19

09 May '19

Hello oVirt community, Seems lik a bug. I don't have more than one environment to test on so I can't be 100% sure and didn't want to file a report (but didn't know where else to report this). I have a fresh install self hosted ovirt cluster 4.3.1.1-1.el7. When I build any logical network adapter with a "-" in the name ex "guest-network-01" the network interface names appear on the hosts (using ip addr command) as garbled names like on8cd19bc011414. They still appear to work, but when you try to make a VNic profile based on the broken name the VMs fail to boot, the VM has to be killed via command line on each host afterwards (they try to boot and hang on all hosts in the cluster corrupting the disk of the VM) because it can't find the parent logical network interface by name. Example errors: VM Security-Onion is down with error. Exit message: (1, 'Cannot find device "guest-dmz-ne"\n', ['/sbin/tc', 'qdisc', 'add', 'dev', 'guest-dmz-network', 'ingress']). VDSM ovirt-2 command DestroyVDS failed: General Exception: ('(1, \'Cannot find device "guest-dmz-ne"\\n\', [\'/sbin/tc\', \'filter\', \'show\', \'dev\', \'guest-dmz-network\', \'parent\', \'ffff:\'])',) That took me a very long time to figure out and broke many vms in the process =(

many 4.2 leftovers after upgrade 4.3.3

Hello everybody, after the upgrade of ovirt-engine node I have several packages still pointing from 4.2 repo. Actually everything is working as expected. yum clean all&& yum upgrade does not find any updates, but reinstall bringing same packages from the 4.3 repo for example: *yum reinstall safelease.x86_64 Loaded plugins: changelog, fastestmirror, langpacks, vdsmupgrade, versionlockRepository centos-sclo-rh-release is listed more than once in the configurationLoading mirror speeds from cached hostfile * base: centos.mirrors.as250.net <http://centos.mirrors.as250.net> * centos-qemu-ev: ftp.rz.uni-frankfurt.de <http://ftp.rz.uni-frankfurt.de> * extras: ftp.rrzn.uni-hannover.de <http://ftp.rrzn.uni-hannover.de> * ovirt-4.3: ftp.nluug.nl <http://ftp.nluug.nl> * ovirt-4.3-epel: mirror.infonline.de <http://mirror.infonline.de> * updates: centos.mirrors.as250.net <http://centos.mirrors.as250.net>Resolving Dependencies--> Running transaction check---> Package safelease.x86_64 0:1.0-7.el7 will be reinstalled--> Finished Dependency ResolutionDependencies Resolved============================================================================================================================================================================================== Package Arch Version Repository Size==============================================================================================================================================================================================Reinstalling: safelease x86_64 1.0-7.el7 ovirt-4.3-centos-ovirt43 21 kTransaction Summary==============================================================================================================================================================================================Reinstall 1 PackageTotal download size: 21 kInstalled size: 43 kIs this ok [y/d/N]: * But we have many others, should I reinstall them manually to get right packages? *yum list installed | grep ovirt-4.2Repository centos-sclo-rh-release is listed more than once in the configurationcollectd.x86_64 5.8.1-4.el7 @ovirt-4.2-centos-opstoolscollectd-disk.x86_64 5.8.1-4.el7 @ovirt-4.2-centos-opstoolscollectd-postgresql.x86_64 5.8.1-4.el7 @ovirt-4.2-centos-opstoolscollectd-write_http.x86_64 5.8.1-4.el7 @ovirt-4.2-centos-opstoolscollectd-write_syslog.x86_64 5.8.1-4.el7 @ovirt-4.2-centos-opstoolsgdeploy.noarch 2.0.8-1.el7 @ovirt-4.2-centos-gluster312nbdkit.x86_64 1.2.7-2.el7 @ovirt-4.2-epelnbdkit-plugin-python-common.x86_64 1.2.7-2.el7 @ovirt-4.2-epelnbdkit-plugin-python2.x86_64 1.2.7-2.el7 @ovirt-4.2-epelnbdkit-plugin-vddk.x86_64 1.2.7-2.el7 @ovirt-4.2-epelovirt-ansible-disaster-recovery.noarch 1.1.4-1.el7 @ovirt-4.2ovirt-ansible-image-template.noarch 1.1.9-1.el7 @ovirt-4.2ovirt-ansible-manageiq.noarch 1.1.13-1.el7 @ovirt-4.2ovirt-ansible-roles.noarch 1.1.6-1.el7 @ovirt-4.2ovirt-engine-cli.noarch 3.6.9.2-1.el7.centos @ovirt-4.2ovirt-js-dependencies.noarch 1.2.0-3.1.el7.centos @ovirt-4.2python-linecache2.noarch 1.0.0-1.el7 @ovirt-4.2-centos-ovirt42python-testtools.noarch 1.8.0-2.el7 @ovirt-4.2-centos-ovirt42python2-asn1crypto.noarch 0.23.0-2.el7 @ovirt-4.2-centos-ovirt42python2-cffi.x86_64 1.11.2-1.el7 @ovirt-4.2-centos-ovirt42python2-chardet.noarch 3.0.4-7.el7 @ovirt-4.2-centos-opstoolspython2-crypto.x86_64 2.6.1-16.el7 @ovirt-4.2-epelpython2-cryptography.x86_64 2.1.4-2.el7 @ovirt-4.2-centos-ovirt42python2-ecdsa.noarch 0.13-10.el7 @ovirt-4.2-epelpython2-extras.noarch 1.0.0-2.el7 @ovirt-4.2-centos-ovirt42python2-fixtures.noarch 3.0.0-7.el7 @ovirt-4.2-centos-ovirt42python2-idna.noarch 2.5-1.el7 @ovirt-4.2-centos-opstoolspython2-pyOpenSSL.noarch 17.3.0-3.el7 @ovirt-4.2-centos-ovirt42python2-pysocks.noarch 1.5.6-3.el7 @ovirt-4.2-centos-opstoolspython2-requests.noarch 2.19.1-4.el7 @ovirt-4.2-centos-opstoolspython2-traceback2.noarch 1.4.0-14.el7 @ovirt-4.2-centos-ovirt42python2-urllib3.noarch 1.21.1-1.el7 @ovirt-4.2-centos-opstoolssafelease.x86_64 1.0-7.el7 @ovirt-4.2-centos-ovirt42vdsm-jsonrpc-java.noarch 1.4.15-1.el7 @ovirt-4.2* Thanks,Arman.

Hi, I'm trying to attach an USB device to a VM but although the host detects the USB device (is shown in lsusb), the host device tab in the VM is not showing that device. It show all other but not that one. Is there something I should do to update ovrit host devices? Regards

Creating Thin-provisioned disks on a gluster volume
by Dmitry Filonov 08 May '19

08 May '19

Hi - We want to migrate our aging oVirt cluster to a new one and decided to go for the hyperconverged setup with Gluster and hosted engine. Got 3 new machines, set everything up, did a test VM migration and were almost ready to do final migration of our VMs when I notice one really weird thing. When migrating VMs from NFS storage onto Gluster they stay thin provisioned. But if I try creating new disk image from the oVirt GUI - I get preallocated volume. No matter if I select "thin provision" or "Preallocated" I always get preallocated volume created.

Hosted engine restore went very wrong
by Andreas Elvers 07 May '19

07 May '19

I really feel like an idiot. I tried to move our hosted engine from our Default datacenter to our Ceph Datacenter. I ran intro problems which were correctly addressed. see: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/ZFCLFWRN6XR6KM… It was in case a race condition. I was able to bring back the engine to our Default Cluster. And then I tried to do the move again to our Ceph Datacenter. I got the error "The target Data Center does not contain the Virtual Disk" twice yesterday. Because it was late, I decided to do it in the next morning. I did a new backup from the engine. Copied it over to the new node of the Ceph Datacenter and started the hosted-engine --deploy. But I FORGET TO SHUTDOWN the other engine! Oh man. The deploy script errored out with: [ ERROR ] fatal: [localhost]: FAILED! => {"censored": "the output has been hidden due to the fact that 'no_log: true' was specified for this result", "changed": false} [ ERROR ] fatal: [localhost -> engine.infra.solutions.work]: FAILED! => {"changed": false, "msg": "There was a failure deploying the engine on the local engine VM. The system may not be provisioned accord Then I realised something was different this time. I shutdown and undefined the Local Engine. The node is now in a degraded state. Is it possible to start the deployment again on a degraded node? I started the old engine again, but I'm not able to reach the login page. Any Idea what to do next?

Re: Best arquitecture for 2 location
by Strahil 07 May '19

07 May '19

You may use gluster with geo-replucation, but that doesn't support gluster updates from remote to local side, so the second location is your DR site and nothing else should be running. Maybe Simone/Sahina can clarify the ovirt part of the setup.

replaced ovirt certs, now i'm locked out with unable to find valid certification path
by michael＠wanderingmad.com 07 May '19

07 May '19

I followed the guide here to replace the self-signed certs with 3rd party certs, and now i'm getting this error on signin: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target do i need to have the .p12 in place also? I extracted the .key and .cer from the existing PFX, and copied them to all the places in the article, renaming the .cer to .pem as neded and I always get that error. Yes, I did copy to the java directory and ran the program to update the trust store, and I can list out the trust store and see it listed. Has there been a recent change in how it handles certs? I tried it with the blank password for the certstore, with "changeit" and also changing the password to "123456" and none work.

Problem with restoring engine
by Andreas Elvers 06 May '19

06 May '19

Hello today I tried to migrate the hosted engine from our Default Datacenter (NFS) to our Ceph Datacenter. The deployment worked with the automatic "hosted-engine --deploy --restore-from-file=backup/file_name" command. Perfect. Only thing is: I messed up with the cluster name. The name should be Luise01 but I entered Luise1. Duh... Now I want to bring the engine back to the Default Datacenter. Easy thing. Just repeat the same steps again. 1. Enable global ha maintenenace 2. Stop and disable the engine 3. create the engine backup 4 ... continue with all the steps from chapter 13.1.8 RHEV Docs 4.3 Beta. Everything looked great. The ansible playbook was running, then asking for the storage domain. I entered the NFS path. It got registered, but then the ansible playbook errors out with [ INFO ] TASK [ovirt.hosted_engine_setup : Add VM] [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Cannot attach Virtual Disk. The target Data Center does not contain the Virtual Disk.]". HTTP response code is 409. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Cannot attach Virtual Disk. The target Data Center does not contain the Virtual Disk.]\". HTTP response code is 409."} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook [ INFO ] Stage: Clean up [ INFO ] Cleaning temporary resources I see that there is a bug report on https://bugzilla.redhat.com/show_bug.cgi?id=1649424 Any idea how to get around this error ? Additionally I now have a HostedEngineLocal (shut off) on that node... How do I remove it? engine-cleanup ? Have to get some sleep. best regards.

NonResponsive Host and unknown VMs
by Alexis Grillon 06 May '19

06 May '19

Hello, Context : (probably) After a failed deletion of snapshot during a backup (it had been somes times since i got this problem), one of my host has gone Nonresponsive, and with him, all the VMs who was stored on it or run on it. Instead of removing the problem snapshot (usually it does the trick). I did reboot the host (and without maintenance, it wasn't available) On the Host log, it seems there's nothing wrong, on the Engine log, there's mostly a "ERROR [org.ovirt.engine.core.dal.dbbroker. auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-10) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM xxx command Get Host Capabilities failed: Message timeout which can be caused by communication issues", without further informations. One last thing, it seems gluster is working well but the command "gluster volume status" goes timeout (nothing from log seems wrong) Of course, the host ping from the engine, and the engine ping from the host. You'll find on the bottom of the mail more informations about the setup. Here are a few questions if someone can help : - Should i open a bug on that (looks a lot like https://bugzilla.redhat.com/show_bug.cgi?id=1404082 but i can't do all the test of this bug) ? - Should i be worried about the gluster timeout (the engine is on it) / should i move the gluster point of the unresponsive host on another, and remove the unresponsive host from the pool to fix that ? - i guess that if i fix the unresponsivness of the host, it'll fix the vm (that one is an easy one i hope !) - Once i will have found why the host is unresponsive, and if i can't fix it (have to reinstall it by example), how can i remove the host and the affected vms from the cluster (nearly everything is unavailable on them, maintenance for storage and host are unavailable) ? Any help will be greatly appreciated, thank you. Informations about the setup : ovirt 4.2.8.2 Gluster has been created on system before the installation of ovirt (but is well working this way). Mostly, storage of VMs are made with NFS mount on host, not on a gluster exception made for the engine. The unresponsive host is the arbiter brick of the gluster volumes. I can wipe the unresponsive host, but the cluster is a production cluster, i can't shutdown everything :) ---- Cordialement, Alexis Grillon Pôle Humanités Numériques, Outils, Méthodes et Analyse de Données.

Cascade Lake CPU in oVirt
by Matthias Leopold 06 May '19

06 May '19

Hi, do I get it right that hypervisor hosts with Cascade Lake CPU could be used in oVirt, but would be recognized as "Skylake"? Cascade Lake specific features could only be used in VMs after CL is supported by libvirt (https://bugzilla.redhat.com/show_bug.cgi?id=1677209) and this libvirt is imported in oVirt? We're thinking about buying new hardware and I want to be sure it can be used... thx matthias

Q35 in pre 4.3 updated environments?
by Gianluca Cecchi 06 May '19

06 May '19

Hello, having some environments born before 4.3.0 and Q35 introduction. Now on 4.3.3, but of course existing VMs seem not impacted and retain their machine type, eg a dumpxml gives: <type arch='x86_64' machine='pc-i440fx-rhel7.6.0'>hvm</type> Any advise if I want to update any of them to Q35 (supposing their installed OS does support that kind of hw emulation, of course)? Apart from shutdown, edit, system, advanced parameters, change, save and boot? This question leads me to something strange I have noticed: updating cluster to 4.3, when 4.3.0 was released, seems not to have changed default "Emulated Machine" type for it. In fact if I go in my cluster, I see it still with value "pc-i440fx-rhel7.6.0", even if its compatibility version is 4.3. Is this expected? If I edit the cluster I don't see an option to change to q35. My cpu type is "Intel Westmere IBRS SSBD Family", could it influence this situation in any way? Thanks in advance, Gianluca

Migrating from RHV to ovirt
by Andrés Jiménez 06 May '19

06 May '19

Hi, all I do have a 5 hosts cluster with over 300 VMs in production with Red Hat Virtualization version 4.2.8 and I am willing to switch to a pure CentOS + oVirt 4.2 setup. Management is based in a RHVM hosted-engine in a dedicated iSCSI DataStore and our hosts are a mix of RHVH nodes (3) and CentOS with oVirt 4.2 repositories (2). I was wondering if I can just set up a new hosted-engine in a CentOS host and recover a backup of our current ovirt- engine (rhvm). Would that work straight away without affecting my running VMs?

Please Help, Ovirt Node Hosted Engine Deployment Problems 4.3.2
by Todd Barton 06 May '19

06 May '19

I've having to rebuild an environment that started back in the early 3.x days. A lot has changed and I'm attempting to use the Ovirt Node based setup to build a new environment, but I can't get through the hosted engine deployment process via the cockpit (I've done command line as well). I've tried static DHCP address and static IPs as well as confirmed I have resolvable host-names. This is a test environment so I can work through any issues in deployment. When the cockpit is displaying the waiting for host to come up task, the cockpit gets disconnected. It appears to a happen when the bridge network is setup. At that point, the deployment is messed up and I can't return to the cockpit. I've tried this with one or two nic/interfaces and tried every permutation of static and dynamic ip addresses. I've spent a week trying different setups and I've got to be doing something stupid. Attached is a screen capture of the resulting IP info after my latest try failing. I used two nics, one for the gluster and bridge network and the other for the ovirt cockpit access. I can't access cockpit on either ip address after the failure. I've attempted this setup as both a single host hyper-converged setup and a three host hyper-converged environment...same issue in both. Can someone please help me or give me some thoughts on what is wrong? Thanks! Todd Barton

Stale hosted engine node information harmful ?
by Andreas Elvers 02 May '19

02 May '19

I have 5 nodes (node01 to node05). Originally all those nodes were part of our default datacenter/cluster with a NFS storage domain for vmdisk, engine and iso-images. All five nodes were engine HA nodes. Later node01, node02 and node03 were re-installed to have engine HA removed. Then those nodes were removed from the default cluster. Eventually node01,02 and 03 were completely re-installed to host our new Ceph/Gluster based datecenter. The engine is still running on the old default Datacenter. Now I wish to move it over to our ceph/gluster datacenter. when I look at the current output of "hosted-engine --vm-status" I see: --== Host node01.infra.solutions.work (id: 1) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : node01.infra.solutions.work Host ID : 1 Engine status : unknown stale-data Score : 0 stopped : True Local maintenance : False crc32 : e437bff4 local_conf_timestamp : 155627 Host timestamp : 155877 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=155877 (Fri Aug 3 13:09:19 2018) host-id=1 score=0 vm_conf_refresh_time=155627 (Fri Aug 3 13:05:08 2018) conf_on_shared_storage=True maintenance=False state=AgentStopped stopped=True --== Host node02.infra.solutions.work (id: 2) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : node02.infra.solutions.work Host ID : 2 Engine status : unknown stale-data Score : 0 stopped : True Local maintenance : False crc32 : 11185b04 local_conf_timestamp : 154757 Host timestamp : 154856 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=154856 (Fri Aug 3 13:22:19 2018) host-id=2 score=0 vm_conf_refresh_time=154757 (Fri Aug 3 13:20:40 2018) conf_on_shared_storage=True maintenance=False state=AgentStopped stopped=True --== Host node03.infra.solutions.work (id: 3) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : node03.infra.solutions.work Host ID : 3 Engine status : unknown stale-data Score : 0 stopped : False Local maintenance : True crc32 : 9595bed9 local_conf_timestamp : 14363 Host timestamp : 14362 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=14362 (Thu Aug 2 18:03:25 2018) host-id=3 score=0 vm_conf_refresh_time=14363 (Thu Aug 2 18:03:25 2018) conf_on_shared_storage=True maintenance=True state=LocalMaintenance stopped=False --== Host node04.infra.solutions.work (id: 4) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : node04.infra.solutions.work Host ID : 4 Engine status : {"health": "good", "vm": "up", "detail": "Up"} Score : 3400 stopped : False Local maintenance : False crc32 : 245854b1 local_conf_timestamp : 317498 Host timestamp : 317498 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=317498 (Thu May 2 09:44:47 2019) host-id=4 score=3400 vm_conf_refresh_time=317498 (Thu May 2 09:44:47 2019) conf_on_shared_storage=True maintenance=False state=EngineUp stopped=False --== Host node05.infra.solutions.work (id: 5) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : node05.infra.solutions.work Host ID : 5 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 0711afa0 local_conf_timestamp : 318044 Host timestamp : 318044 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=318044 (Thu May 2 09:44:45 2019) host-id=5 score=3400 vm_conf_refresh_time=318044 (Thu May 2 09:44:45 2019) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False The old node01, node02 and node03 are still present. The new incarnations of node01, node02 and node03 will be the destination the the deployment of the new home of our engine to which I wish to restore the backup to. But I'm not sure, if (and how) the old date should be removed first.

oVirt 4.3.3 - servers cannot be reached
by Wood Peter 02 May '19

02 May '19

Hi, I setup AD authentication and from command line all looks good. Unfortunately, on the Web UI users sometimes login successfully but most of the times the login screen just hangs and after 2-3 min. it displays "Unable to log in because servers cannot be reached. Try again later." In engine.log I see this: 2019-05-02 11:12:11,581-07 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-72) [] EVENT_ID: USER_VDC_LOGIN_FAILED(114), User peter(a)ad.mycompany.com connecting from '10.12.29.48' failed to log in : 'Unable to log in because servers cannot be reached. Try again later.'. 2019-05-02 11:12:11,583-07 ERROR [org.ovirt.engine.core.sso.servlets.InteractiveAuthServlet] (default task-68) [] Cannot authenticate user 'peter(a)ad.mycompany.com' connecting from '10.12.29.48': Unable to log in because servers cannot be reached. Try again later. Even when my login attempt on the Web UI is hanging I can still successfully run the login test from shell: ovirt-engine-extensions-tool aaa login-user --profile=ad.mycompany.com --user-name=peter The above command never fails. That makes me wonder why am I getting the "servers cannot be reached" error? I assume the AD servers cannot be reached but from the command line it works perfect every time. Any idea what could be the problem or where to look for the error. Thank you, -- Peter

Prevent Gluster Volume being monitored by oVirt
by smirta＠gmx.net 02 May '19

02 May '19

Dear all We are running a oVirt GlusterFS hyperconverged setup with arbiter version 4.2.6.4-1.el7 here. It looks like we are affected by this bug https://bugzilla.redhat.com/show_bug.cgi?id=1614430 with one or more gluster volumes that are not storage domains of oVirt. Is there a way to exclude them from monitoring (vdsm-gluster) or to prevent being added to the engine's database? Thanks Simon
