Alma linux 10 beta issue in virtualbox

Hi, i’m trying to run almalinux 10 on virtualbox but got the message about that my processor i90 9900x will be removed, so i assume that the 10th version will not support anymore this processor

RHEL 11 may remove it, whether AlmaLinux will readd support for it is another question.

so it’s strange because seems like in the 10 beta doesn’t working

RHEL is increasing the architecture version baseline to v3 dropping support for numerous older CPUs (and some newer ones). In AlmaLinux OS 10, developers will follow Red Hat’s decision to ship x86-64-v3 optimized binaries by default, but also will provide additional x86-64-v2 architecture ONLY for older hardware. So my question is did you try install x86_64_v2 ?

The RHEL 10 will require x86-64-v3 “microarchitecture level” x86-64 - Wikipedia
whose features match the 2013 Intel Haswell architecture (AVX2).

The Intel i9 9900X X-Series was released 2018 and has even AVX512, so probably is x86-64-v4 level. It should have no problem here.

Alma does build 10-beta also with x86-64-v2 requirement, but as said that should not be the issue.


Message from whom? With hypervisor there is possibility that the hypervisor (virtualbox) does not pass all CPU features to VM (by default).

i don’t know… but alma linux 9 works witho9ut any issue on virtualbox, i’ve got the message in virtualbox if i remember

You definitely can test with the x86_64_v2 images: Index of /almalinux/10.0-beta/isos/x86_64_v2/

If those start ok, while the default x86_64_v3 image does not, then we know that issue is therein.


You can also boot the baremetal machine with these images.
While it starts installer, you can abort before it touches anything.

If the hardware does not support x86_64_v3, then the installer fails to start at all.
If x86_64_v3 can start on baremetal, but not in virtualbox, then issue is with virtualbox.

yes i’ll can try that, i’ll let you know soon
