oVirt Node install with Foreman VG issue
by simon＠justconnect.ie 28 Feb '21

28 Feb '21

Hi All, I have a server with a RAID1 disk for sda and RAID 5 disk for sdb. Following default install, prior to Cockpit Gluster and Engine wizards there is only a single Volume Group which doesn’t allow me to continue. If I manually configure the install and deselect sdb it gives other issues with multipath but at least I can resolve those. Is there a specific kickstart confuguration that should be used? Kind Regards Shimme

Re: oVirt Node install with Foreman VG issue
by Simon Scott 28 Feb '21

Thanks Strahil, Unfortunately changing the filter is done after the initial install. We manually partition sda so that sdb isn’t touched during install. The issues with multipath grabbing sdb are ongoing with a possible manual fix being tested now. Testing has paused at the moment as we have lost gluster on the arbiter node as per https://lists.ovirt.org/archives/list/users@ovirt.org/thread/U64MGWSUCFJRIV… which looks like a full oVirt rebuild again. Any help on that thread would be appreciated. Thanks again Shimme On 28 Feb 2021, at 08:35, Strahil Nikolov <hunter86_bg(a)yahoo.com> wrote: Most probably there is an LVM filter.

Reinstalled Host 4.4.4 bricks failing to start
by simon＠justconnect.ie 28 Feb '21

28 Feb '21

3 Node HCI - Local Storage Replica 2+1 After changing the Cluster 'Default Network Provider' from ovirt-provider-ovn to 'No Default Provider' notification (as expected) to reinstall was flagged against each host. Host 3 (Arbiter) was reinstalled but failed to Activate due to Gluster Bricks not starting. No GlusterFS process for the bricks is listed when checking Status of glusterd. Please can someone help to identify the issue and resolution. Attempted further reinstallation of the Host fails. Kind Regards Shimme

oVirt 4.2 cluster upgrade
by Fedele Stabile 26 Feb '21

26 Feb '21

I have a 3 node oVirt 4.2.1 cluster, i'm using a self-hosted engine architecture and storage-engine is on a glusterfs replica 3 of the cluster. The oldest CPU is SandyBridge family (E5-2609) and incidentally I have connectivity problems with IPMI NIC of one node, but Hosted Engine HA is enabled and working. Is it safe to upgrade to the last oVirt 4.4 without a down of vm running on the cluster? May I just click on the button Upgrade that appears on the host page?

[ANN] oVirt 4.4.5 Seventh Release Candidate is now available for testing
by Lev Veyde 25 Feb '21

25 Feb '21

oVirt 4.4.5 Seventh Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Seventh Release Candidate for testing, as of February 25th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG is already available for CentOS Linux 8 - We found a few issues while testing on CentOS Stream so we are still basing oVirt 4.4.5 Node and Appliance on CentOS Linux.

Starting a defined VM on a different host
by lavi.buchnik＠exlibrisgroup.com 25 Feb '21

25 Feb '21

Hi, I might be missing something here, but I'm looking for the right API way to start a defined VM on a different host. The scenario is this: 1. VM is running under Cluster Affinity Host. and there is a need to cold migrate it to another host on that Affinity. 2. for that I will stop the VM. 3. And now I would like to start the VM on another host, I tried few ways like: vm_service.start( vm=types.Vm( host=types.Host( name='<host name>' ), ) ) But VM keep starting on the current host. Can you please show me the right way to do it. Thanks, Lavi

25 Feb '21

I am having some issues figuring out how to get a list of VMs and the host that they are running on. I seem to be able to get a reference to the host object, but can't see how to print the name of the host. See the below code snippet: #! /usr/bin/python import ovirtsdk4 as sdk import ovirtsdk4.types as types connection = sdk.Connection( url='https:/<redacted>:443/ovirt-engine/api', username='admin@internal', password='<redacted>', ca_file='ovirt-engine_ca.crt', ) vms_service = connection.system_service().vms_service() vms = vms_service.list() for vm in vms: print("VM.name = " + vm.name) vm_service = vms_service.vm_service(vm.id) #vm = vm_service.get() print(vm.status) if vm.name == 'vmexample': print("HERE") print(vm.host) print(vm.host.name) connection.close() OUTPUT: VM.name = vmexample up HERE <ovirtsdk4.types.Host object at 0x7f5ca250e810> None What am I missing?

Q35: disk type view not consistent in edit vm and new disk pages
by Gianluca Cecchi 24 Feb '21

24 Feb '21

Hello, if I create a VM and select Q35 machine type, still the General --> create image option in edit phase doesn't show sata as an option. Even if I create the VM without disks and then go to edit General --> create, I only see IDE, VirtIO-SCSI and VirtIO. Instead if I click VM name, DIsks --> New, I can select VirtIO-SCSI, VirtIO and SATA After the first disk (SATA in my case) has been created, now if I go and edit VM --> General --> Instance Images + --> Create, I see consistent options. I think GUI experience could be improved. Also because I can reproduce this workflow converging to an error (even if IDE disks are not so common nowadays...): New VM In general I create an IDE disk In System I select in Advanced parameters, Custom Chipset/Firmware Type Q35 (EFI or BIOS based) go ahead At the final OK I get the error: Cannot add Virtual Disk: The disk interface is not supported by the VM OS: Other OS. The result is VM created but without the IDE disk as not supported in Q35 type. Tested in 4.4.4 Gianluca

Cannot add VM. Maximum number of threads per cpu exceeded
by Lavi.Buchnik＠exlibrisgroup.com 24 Feb '21

24 Feb '21

Hi, We have a strange thing, which not clear to us. When provisioning a new VM via REST API, if the number of vCPU for that VM is more than 16, I'm getting this error: Fault reason is "Operation Failed". Fault detail is "[Cannot add VM. Maximum number of threads per cpu exceeded]". HTTP response code is 409. Our version is: Version 4.3.6.6-1.0.9.el7 Note that manual provisioning from the UI do not produce any error when using vCPU > 16. It seems like the issue is related to this setting (from the engine): [root@olvmengine01 ~]# engine-config -g MaxNumOfThreadsPerCpu MaxNumOfThreadsPerCpu: 8 version: 4.1 MaxNumOfThreadsPerCpu: 8 version: 4.2 MaxNumOfThreadsPerCpu: 8 version: 4.3 [root@olvmengine01 ~]# But when trying to set it to another number, I'm always get this error, for example: [root@olvmengine01 ~]# engine-config -s MaxNumOfThreadsPerCpu=10 Please select a version: 1. 4.1 2. 4.2 3. 4.3 3 Cannot set value 10 to key MaxNumOfThreadsPerCpu. Questions: 1. Can you please explain why we getting this error: "Cannot add VM. Maximum number of threads per cpu exceeded"? 2. Is it related to engine-config -g MaxNumOfThreadsPerCpu? 3. Why it is working manually via the UI? 4. if its related to engine-config, why we can't set it to another number? Thanks in advance, Lavi

VM Portal. User can't access the details box
by Nicolás 24 Feb '21

24 Feb '21

Hi, We're running oVirt 4.1.8. We make an intense use of the VM Portal, as our students use it to access and handle their machines. We're currently having an issue with just one of our users. He claims that he created a VM, and when tried to edit its details (clicking on the pencil), a screen stating that the "VM Portal is experiencing some issues" is shown (screenshot added). I granted a UserRole permission on a user I handle, and I don't experience that problem, I can edit the VM with no issues. The user also states that this happens on any VM he creates. I see nothing relevant in the log regarding this issue. Please, any hint how to debug this? Thanks. Nicolás

Did you install ovirt-guest-tools on the VM from the iso available at your engine vm package? Did the related service start in WIndows 10 OS? You didn't reply why you are forced to use so an "old" oVirt version: it is not old in absolute, but oVirt is rapidly evolving and you should stay at maximum behind one version. So if the latest is 4.3, stay no behind 4.2. Now, with 4.4 out since many months, stay no behind 4.3 at least... This way you get more correct help because more guys are on latest versions, that got many enhancements and many bug fixes (eg with snapshot management, illegal disks state some time, and so on) Gianluca

Invalid status on Data Center Default. Setting status to Non Responsive.
by Jelte Veldstra | Order2Cash 23 Feb '21

23 Feb '21

All, We have built a new oVirt cluster from scratch. We used the 4.4.4 installer released in December 2020. When deploying the engine we had the wizard create a Gluster volume for the engine on three hosts. All went well and the cluster is starting to take shape. When starting the engine we do see the following error each time the engine is started in /var/log/ovirt-engine/engine.log: 2021-02-23 08:06:09,208+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-33) [4293beae] EVENT_ID: SYSTEM_CHANGE_STORAGE_POOL_STATUS_PROBLEMATIC(980), Invalid status on Data Center Default. Setting status to Non Responsive. Also when navigating in the engine web-ui to Compute -> Data Centers -> Default and check the events an event of id 980 is shown with the message: “Invalid status on Data Center Default. Setting status to Non Responsive.”. The date/time matches when the error is shown in the engine log. The datacenter overview does not show any warnings or errors and lists the Default datacenter as status Up. An interesting observation is that the cluster overview does have a status column on the far left, but the status is not mentioned. The field underneath the status heading is empty. Could that be the unknown status that the data center refers to? How could we investigate this further? The storage volumes do not show any issues and the cluster seems to function okay (it has not been used a lot yet as it has been built yesterday/today), but the error message does sound like something we need to get out of the way before we put the actual workload on it.

Hi Joseph, Somehow I missed your email. I am thinking in similar direction, but in all honesty, it’s takes bit of effort to accept that we need complete platform deployment from 4.3 to 4.4, considering EL 8 is required, to have this fixed. Anyway, let’s try re-deploying engine with current platform version in testing env, take our notes and share them. This is actually nice, team work. 😊 For now, in production, I am going to increase the RAM and CPU, and if reboot is required, just do it again. Too many CI/CD deployment failures, to leave the engine process fighting for resources. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

Re: oVirt Engine increase RAM and CPU (Joseph Goldman) ---------------------------------------------------------------------- Date: Tue, 23 Feb 2021 17:22:48 +1100 From: Joseph Goldman <joseph(a)goldman.id.au> Subject: [ovirt-users] Re: oVirt Engine increase RAM and CPU To: users(a)ovirt.org Message-ID: <a8b53498-170b-e6c4-4c86-f8f0df8b46f8(a)goldman.id.au> Content-Type: multipart/alternative; boundary="------------28E9B49759C19EA5FB57BA34" This is a multi-part message in MIME format. --------------28E9B49759C19EA5FB57BA34 Content-Type: text/plain; charset=windows-1252; format=flowed Content-Transfer-Encoding: quoted-printable Hi Marko, =A0I have also had this problem on an oVirt 4.3 install - I could never=20 fix it and have not tried to upgrade to 4.4 yet - my workaround for now=20 (as you have deduced) is to just 'up' it while running so its hotswapped=20 in - annoying, but I think the best way around this without upgrade=20 would be to re-deploy the hosted engine defining the new resources using=20 an engine-backup - but again this is just as scary as in-place upgrade=20 lest you lock yourself out from your other running VMs in a production=20 environment. =A0I plan to do it - I just need some time to set it up in a lab so I=20 know what to expect.

There are different parameters around memory - are you sure you change the correct one(s)? Also adding Arik. Arik - please see the history of this thread. It might be an issue in the engine, or in hosted-engine HA, or both - not sure. > But before I do that, we are currently on 4.3.8.2 version – is this by any change fixed by latest 4.3 version? No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it reproduces, file a bug and attach all relevant logs (including engine, vdsm, hosted-engine-ha).

Re: oVirt Engine increase RAM and CPU

Hi Marko, I have also had this problem on an oVirt 4.3 install - I could never fix it and have not tried to upgrade to 4.4 yet - my workaround for now (as you have deduced) is to just 'up' it while running so its hotswapped in - annoying, but I think the best way around this without upgrade would be to re-deploy the hosted engine defining the new resources using an engine-backup - but again this is just as scary as in-place upgrade lest you lock yourself out from your other running VMs in a production environment. I plan to do it - I just need some time to set it up in a lab so I know what to expect.
