Old cpu not support new operator [CPU does not support x86-64-v2]

[nut-api]

I deploy strimzi operator version 0.46.0 and have this error Fatal glibc error: CPU does not support x86-64-v2, what a workaround for this if I want to use kafka version 4.

My machine:
CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Strimzi operator version: 0.46.0
Using KVM running on proxmox to form k8s cluster

I am not sure if a workaround exists for such an issue. I mean, currently our images our based on UBI9. UBI9 requires a CPU with v2 features. I am not familiar with `proxmox ', is that some kind of infrastructure as a service where you can manage your VMs? If so, then I would try to have a different CPU type/flavor machines which has those v2 features. But maybe @strimzi/maintainers has better idea.

I do not think we will do anything special to support some old CPUs. So, assuming this is about the physical CPU and not about some virtualization layer, the only option would be to rebuild Strimzi from source with some base image that supports it.

PS: Nobody else reported this, not sure if your CPU is that old / rare so that only you have this problem.
PS2: We use the UBI9 images already for some time, it is not new in 0.46. But it is possible that something changed in the UBI9 image just recently.

I found this issue on keycloak (keycloak/keycloak#17290)
They also use the UBI9 as a base image and encounter the same problem when using it on a Proxmox VM with the default CPU setting.

They said that with kvm64, which is the default setting for CPU type, has a limited set of instructions for the VM's OS (missing SSE4.2, which UBI9 requires).
I just changed the VM CPU type to host and it worked! 🎉

Thanks for your fast response.

Glad it works now. And thanks for providing the details on how you solved it! 👍

Great @nut-api! 👍
