Thanks Clark for follow-up.
My explanation was not correct, and I should have said RSA + SHA1 no longer
Our problem was that the key generated by create keypair api in nova uses
RSA + SHA1
thus ssh by tempest with that key no longer works since SHA1 was disabled
in a recent update
in CentOS 9 Stream.
