Description: We are facing an issue while starting the Elasticsearch/Kibana service on the current virtual machine. The application fails during startup because the host CPU does not support the instruction sets required by the bundled executable/image. Error Observed: ```root@virtkibana:~# journalctl -u elasticsearch.service --no-pager May 08 04:19:04 virtkibana systemd[1]: Starting elasticsearch.service - Elasticsearch... May 08 04:19:04 virtkibana systemd-entrypoint[8297]: The current machine does not support all of the following CPU features that are required by the image: [CX8, CMOV, FXSR, MMX, SSE, SSE2, SSE3, SSSE3, SSE4\_1, SSE4\_2, POPCNT, LZCNT, AVX, AVX2, BMI1, BMI2, FMA, F16C]. May 08 04:19:04 virtkibana systemd-entrypoint[8297]: Please rebuild the executable with an appropriate setting of the -march option. May 08 04:19:04 virtkibana systemd[1]: elasticsearch.service: Main process exited, code=exited, status=1/FAILURE May 08 04:19:04 virtkibana systemd[1]: elasticsearch.service: Failed with result 'exit-code'. May 08 04:19:04 virtkibana systemd[1]: Failed to start elasticsearch.service - Elasticsearch. Log Reference: May 08 04:19:04 virtkibana systemd-entrypoint[8297]: Please rebuild the executable with an appropriate setting of the -march option. Impact: - Elasticsearch/Kibana service is unable to start. - Portal functionality is unavailable. - Deployment on the current VM/host is blocked. Probable Cause: The deployed Elasticsearch/Kibana image or binary was built targeting newer CPU architectures requiring advanced instruction sets (AVX/AVX2 and related features), which are not available on the current VM host CPU. Required Action: - Verify CPU compatibility on the VM/hypervisor host. - Use a compatible Elasticsearch/Kibana version built for older CPU architectures, OR - Rebuild the executable/image using a lower `-march` target compatible with the current hardware, OR - Migrate the workload to a host supporting AVX/AVX2 instructions. Environment: - Service: Elasticsearch / Kibana - Host Type: Virtual Machine - OS: Linux - Startup Method: systemd Severity: High – Service unavailable. Expected Result: Elasticsearch/Kibana services should start successfully without CPU compatibility errors. ---

As given above, there's a parallel thread on this topic, found [here](https://discuss.elastic.co/t/elasticseach-9-4-0-wont-start-on-nehalem-cpu-does-not-support-all-the-following-cpu-features/386216) As noted there, 9.4.1 does not contain a fix, 9.4.2 might, and the pull request includes a (better temporary) workaround if needed. Maybe also best to watch that other thread for updates going forward. ---

I tried the mention possible solution but it is not working. ---

This looks exactly like a CPU instruction set mismatch issue rather than a service configuration problem. If the VM host doesn’t support AVX/AVX2, newer Elasticsearch/Kibana builds will fail to start because they’re compiled with higher `-march` targets. At this point, the quickest fix is usually either: - confirm CPU flags on the host (`lscpu | grep avx`) - downgrade to an Elasticsearch/Kibana version built for older architectures, or - move the deployment to a VM that supports AVX/AVX2 Rebuilding with a lower `-march` can work too, but in most cases upstream binaries are the real constraint here, so version alignment is usually the cleaner solution. ---

> [@nathan0](#): > > lscpu | grep avx Currently, our virtual environment does not support AVX/AVX2, and we have also downgraded the Elasticsearch version. Could you please confirm whether this issue will be resolved in a future release, or if all future Elasticsearch packages will require CPUs with AVX support? If the latter is the case, migrating the VM to hardware that supports AVX would be mandatory. ---

The issue has been resolved in the latest release, version 9.4.2.
