It doesn't matter if it's a fresh install or import. I go to ui and edit vm and change to one of the default size templates, usually large, it boots with no nic and I can add a nic once it's booted and restart it, then it gets an IP and is fine unless you shut it down. In that case, you have to go through setting size and adding nic after vm boot. Any help would be appreciated. Thanks in advance/

Unable to create a network bond in OLVM
by jdmr4815＠gmail.com 10 Feb '25

10 Feb '25

Good morning all, I'm rather new to this so please forgive my ignorance. I've searched official Oracle documentation, the oVirt administration guide, reddit, LLMs, and about every other source I could find but haven't seen anything that allows me set up a bond successfully. For background, I'm currently using one server as management and another server as a local storage host. I'm not smart enough yet to do network storage. I've tried to create a bond in two ways: the recommended way (in the administration guide, Oracle documentation, etc.) of simply creating a bond within OLVM by dragging/dropping interfaces to form a bond. Also, I've created a bond manually on my management server and verified it was present in the hosts -> network interfaces screen. When I attempt to assign a logical network to the bond, I get some variation of the following in /var/log/vdsm/vdsm.log: from=::ffff:10.90.104.68,37286, flow_id=6d139ffe-d9dc-4993-b050-72baa9eca527 (api:35) 2025-02-10 09:53:11,257-0600 ERROR (jsonrpc/1) [jsonrpc.JsonRpcServer] Internal server error (__init__:343) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/yajsonrpc/__init__.py", line 338, in _handle_request res = method(**params) File "/usr/lib/python3.6/site-packages/vdsm/rpc/Bridge.py", line 186, in _dynamicMethod result = fn(*methodArgs) File "<decorator-gen-508>", line 2, in setupNetworks File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 33, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 1576, in setupNetworks supervdsm.getProxy().setupNetworks(networks, bondings, options) File "/usr/lib/python3.6/site-packages/vdsm/common/supervdsm.py", line 38, in __call__ return callMethod() File "/usr/lib/python3.6/site-packages/vdsm/common/supervdsm.py", line 36, in <lambda> **kwargs) File "<string>", line 2, in setupNetworks File "/usr/lib64/python3.6/multiprocessing/managers.py", line 772, in _callmethod raise convert_to_error(kind, result) libnmstate.error.NmstateVerificationError: desired ======= --- name: bond0 type: bond state: up ipv4: enabled: false ipv6: enabled: false link-aggregation: mode: 802.3ad options: xmit_hash_policy: layer2+3 port: - eno5 - eno6 current ======= --- name: bond0 type: bond state: up ipv4: enabled: false ipv6: enabled: false lldp: enabled: false difference ========== --- desired +++ current @@ -6,10 +6,5 @@ enabled: false ipv6: enabled: false -link-aggregation: - mode: 802.3ad - options: - xmit_hash_policy: layer2+3 - port: - - eno5 - - eno6 +lldp: + enabled: false After some research, it seemed like the solution was to take the "desired" state and use nmstatectl apply filename.yaml to apply the desired state.

Hosted Engine setup issues.
by daznis＠gmail.com 10 Feb '25

10 Feb '25

Hello, I can for figure out what is happening with deployment of my hosted engine setup into a glusterfs cluster. For some unknown reason ansible is getting the IP address of the virbr0 interface which is the default interface created with libvirt installation. Which is down as it's not connected to anything. The error message I'm getting is [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The resolved address doesn't resolve on the selected interface\n"}, But after digging deeper I found that ansible is getting a wrong "he_host_ip" value log snippet: 2025-02-10 15:39:13,484+0200 DEBUG var changed: host "localhost" var "he_host_ip" type "<class 'ansible.utils.unsafe_proxy.AnsibleUnsafeText'>" value: ""192.168.124.1"" How should I proceed to solve this? I'm using bonded interface with a vlan for management network bond0.536.

Gettting VM permissions from ovirt.ovirt ansible colllection
by Colin Coe 10 Feb '25

10 Feb '25

Hi all I'm writing an Ansible playbook to capture VM info, specifically the MAC address and the user permissions, but I'm having issues resolving the user ID returned by ovirt.ovirt.ovirt_vm_info into something I can use, like their userid. ovirt.ovirt.ovirt_vm_info gives me: "vm_facts.ovirt_vms[0].permissions[0]": { "href": "/ovirt-engine/api/vms/39e07b2a-4cbe-48d8-9e03-3a903027c2b0/permissions/00000003-0003-0003-0003-0000000002ad", "id": "00000003-0003-0003-0003-0000000002ad", "role": { "href": "/ovirt-engine/api/roles/00000000-0000-0000-0000-000000000001", "id": "00000000-0000-0000-0000-000000000001" }, "user": { "href": "/ovirt-engine/api/users/fdfc627c-d875-11e0-90f0-83df133b58cc", "id": "fdfc627c-d875-11e0-90f0-83df133b58cc" }, "vm": { "href": "/ovirt-engine/api/vms/39e07b2a-4cbe-48d8-9e03-3a903027c2b0", "id": "39e07b2a-4cbe-48d8-9e03-3a903027c2b0" } } I'm looking to get the userid's of the users assigned to this VM with the "UserRole" role. Any ideas how I can do this with the ovirt.ovirt ansible collection? Thanks

Query on Cluster CPU type in OLVM
by dushyantk.sun＠gmail.com 10 Feb '25

10 Feb '25

1. Does selecting particular "Cluster CPU Type:" while creating cluster has any performance impact on vms. 2. I have Dell and HP servers, while creating cluster if i select intel broadwell or cascadelake cpu type, it shows "Host CPU Type Is Not Compatible With Cluster Properties" 3. Since Intel Nehalem is lowest CPU family version and supporting for old dell/HP, i selected it for my cluster. HOwever vm shows CPU model name "Intel Core i7 9xx (Nehalem Class Core i7)" however same host in vmware shows " Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz" How we can fix this CPu model name.

export very slow
by Enrico Becchetti 06 Feb '25

06 Feb '25

Dear all, I have an Ovirt cluster with 3 Dell R7525 nodes and about 70 virtual machines. I have been using ovirtbackup (python) for a long time to save the VMs. Unfortunately it has always been a very slow process that with time and the ever-increasing size of the VMs has become unusable. The oVirt cluster has two storage domains. "DATA" is a the fibre channel type (8Gbs) with 18TB and an EXPORT domain NFS managed by a dual-processor server HPE Proliant with 4x1Gbs. I'll give you an example. I have a vm with four vdisk for a 1.8TB and these are the steps performed to backup this VM. As you will see it takes many hours to get the clone from the snapshot and then many hours to copy the clone to the NFS storage. How can I reduce the time needed to save ? Thank you !

vms shutdown during boot
by eevans＠digitaldatatechs.com 02 Feb '25

I have an issue with getting vms to run. I get this error: VM is down with error. Exit message: Lost connection with qemu process. 2025-02-02 13:27:55,131-05 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-13) [5ad46633] EVENT_ID: VM_DOWN_ERROR(119), VM DBServer-2-18-2024 is down with error. Exit message: Lost connection with qemu process. I see this in the RedHat portal but I don't have entitement or I wouldn't be here. My setup Centos 9 with Ovirt 4.5 with a seperate node controlling the gluster server and ovirt and three nodes managed by the fourth. I ran this same setup in the past with no problem. I hope one of the RH folks will post the fix. It is a verified issue on the REDHAT portal I appreciate any help yu can give me.

Re: Help With CPU Type
by Jorge Visentini 31 Jan '25

31 Jan '25

Hi. If you do this right, you will need downtime because the VM's processor model will change, even though the VM's processor is only showing the family. Another thing that can happen is that you change the family and the host becomes non-operational in the cluster, so you would have to test that at least. But you can roll back to the original cluster family. I have done this in the past and as far as I remember, the only thing that causes a warning on the VM is that it is running on a different cluster, that's all. Please correct me if I'm wrong. Cheers!

Edit/Change MAC Address Pools
by milad.norouzi1370＠gmail.com 31 Jan '25

31 Jan '25

According to this link: https://www.ovirt.org/documentation/administration_guide/index.html#sect-MA…, we can edit the MAC address pool. Question: If I edit the MAC address pool, what effect will it have on the existing VMs' MAC addresses? Is there any mention in the documentation or elsewhere that indicates this change could be harmful to current configurations?
