I see no other error than that, where are the actual logs? Thanks!

Python SDK - get host VM is running on.
by darkman0101＠hotmail.com 25 Feb '21

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? Thanks, Jason

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

oVirt Ansible cluster deployment
by Jeremey Wise 24 Feb '21

I am trying to eat own dog food. Infrastructure as code... So.. I have taken three physical servers. Setup all the base packages, set NICs, NTP, DNS, collected disk UUIDs etc.. The servers are prepped. And one server has cockpit and ovirt-engine installed... and service started. ############################# --- # This task takes nodes prepaired and deploys cockpit, ovirt deployment and scripts cluster initilization.

If so.. how do you collect feedback etc.. 2) I assume there is a template. Maybe it is published but I could not find it. That I replace (or match) variables of my site that fill in that file. 3) I installed galaxy oVirt.ovirt-ansible-roles but.. how do I know it is deployed on my bastion host? I poked around in the ansible folder.. not seeing anything. And I assume this only is of help POST the above seven steps being done. But maybe this has deployment components and I am missing documents. Thanks, -- p <jeremey.wise(a)gmail.com>enguinpages

Re: guest-agent on windows10 vm

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. Regards, Jelte
