How did you copy the iso to the USB stick? See my Sig below for a link to the wiki page that has some advice about which tools to avoid.

Also, did you check that your downloaded file is not corrupted? There are sha256sums on all the mirrors showing what they should be.

I make flash with dd like in your link

Yes I compare sha256 and no mismatch.

Also when i try to setup Stream 8 i have no problem with it. Only Stream 9 always with this messages about Failed to start Reload Configuration and so on

That does it. The CPU does not support "x86_64-v2" microarchitecture and EL9 does require it.
https://developers.redhat.com/blog/2021 ... ure_levels
Several binaries in RHEL 9 (and CentOS Stream 9 due to their relationship) are compiled so that they use those CPU instructions. If CPU does not have them, then the binaries cannot run.

What has "x86_64-v2"? https://unix.stackexchange.com/question ... -x86-64-v2
That is, CPU should have flags: cx16, lahf, popcnt, sse4_1, sse4_2, and ssse3.

Your Q8200's "Penryn microarchitecture" had SSE 4.1, but it was the next, "Nehalem", that got SSE 4.2.

I think you are right . Thanks a lot. But minimal requirements of Stream 9 was not in plain site like many other things of great import.

Now i know. Thanks.
