i get the below error when i try to add a new kvm host to the cluster. I know that the cpu is a haswell. if i run "virsh capabilities" it returns <model>Haswell-noTSX-IBRS</model>. My KVM server is redhat 8.4 fully patched today on an DL-360 Gen9. oVirt is at 4.4.7.7-1.el8. i have tried many diffent CPU settings for the cluster and none of them work. this is new oVirt install. ERROR: "The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: vmx, model_Haswell-noTSX, nx. Please update the host CPU microcode or change the Cluster CPU Type." MIRCOCODE: root@kvm09 ~]# dmesg | grep 'microcode' [ 0.000000] microcode: microcode updated early to revision 0x46, date = 2021-01-27 [ 1.625108] microcode: sig=0x306f2, pf=0x1, revision=0x46 [ 1.625753] microcode: Microcode Update Driver: v2.2.

Change lease storage domain while VM running
by Gianluca Cecchi 01 Aug '21

01 Aug '21

Hello, on a 4.4.6 environment where I'm moving storage I want to change the lease domain for an HA VM. The VM is running and if I go and edit, change sd and then press ok button, I get a window with: " Changes that can be applied immediately: VM Lease " I don't select the "apply later" check box. But then instead when I confirm, I get an error window with: " vm_name: Cannot edit VM. Hot swapping of VM leases is not supported, please remove the current lease and then set a new one. " Possibly it is possible to hot add a lease but not swap? So I think the first window should be changed. Is this a known issue? No problem if I change the lease storage domain while the VM is powered off. I don't know if it is already fixed in 4.4.7... I'm going to check next days.. Gianluca

When the web UI reports OK (after that 1 sec), do you see a file with the same uuid on that nfs storage ? Maybe you can give some stat output of the file.

How many servers do I need to run oVirt?
by rp.neuli＠yahoo.com 31 Jul '21

31 Jul '21

Hello, sorry for a very basic question. But I searched the net for the basic answer and did not get it. How many servers do I need to run oVirt software? I understand I can access management GUI from anywhere on subnet but naming and they it is explained is confusing to me. I am planning to buy a bigger server (just one to use as compute host) with dual cpu and about 64GB RAM. I am thinking to run my webservers as VM on this proposed machine. I thought it was a level 1 hypervisor (then why does it say some places that I need CentOS or RH on my server?) I also have a FreeNAS server, I was thinking if it was possible to keep my VMs stored on there and run/load/execute them on this so-called-compute server. Will I have to build and keep my VMs (when powered down) on oVirt machine only? finally what will I loose in comparison to free vSphere, if I select oVirt? Thank you. Rajeev

Changing the Password Expiration for a User
by louisb＠ameritech.net 30 Jul '21

30 Jul '21

I've create a new user using ovirt-aaa-jdbc-tool, I'm unable to use the account because the password expiration date has passed. I'm now trying to change the password expiration using the following command: sudo ovirt-aaa-jdbc-tool user edit --password-valid-to=2025-12-31 00:00:00 The above command is not working, I've tried several different formats using double quotes and single quotes, onluy using the date without the time. I've not been able to get anything working, what format should the above command be in? Thanks

VM CPU Topology
by nelson.lameiras＠lyra-network.com 30 Jul '21

30 Jul '21

Hello, We are currently running oVirt 4.3.10 Our oVirt hypervisors (HV) have 2 cpu sockets * 6 cores * HT = 24 vcpu Our VMs (centos7) range globally from 2vcpu to 8vcpu oVirt allows to configure - per VM - the following 3 advanced parameters : virtual_sockets : cores_per_virtual_socket : threads_per_core We make sure that threads per core is always 1 (so no question there) But, for the other 2 parameters, we are unsure of the correct configuration, and if there is a performance penalty on bad configuration. Let's consider a 4vcpu VM 1- Is there a performance difference betwenn 1:4:1 and 4:1:1 configuration ? 2- When should we opt for one or another configuration ? 2- Our VMs total CPU provisionning sum is twice the hypervisors capacity, but they are mostly idle so it is not an issue, but can this influence configuration choice above ? Thank you for any information that can enlighthen us, since we are worried that we are suffering from bad performance due to naive cpu configuration choices.

Upload Image to NFS Storage Domain Doesn't Work
by Nur Imam Febrianto 30 Jul '21

Hi, Lastly in 4.4.6, I have a problem that I couldn’t upload any image to storage domain without clicking Test Connection. Well, after it was acknowledge as a bug and solved at 4.4.7 now I have similar issue. If I upload any image to Storage Domain that uses NFS it only show locked, and then showing OK even if no data are uploaded (can confirm 5GB ISO showing OK after only 1 second). This issue only occurs with NFS backend, another storage domain that uses iSCSI work fine though. Any idea how to solve this ? I’m using NFS Storage Domain for storing ISO and this issue bugged me all the time. Thanks before. Regards, Nur Imam Febrianto
