Trying to run an AlmaLinux 10 container on older x86 hardware, and getting the following?
Fatal glibc error: CPU does not support x86-64-v3

The incantation you're looking for is, from the command line:
podman run --variant=v2 quay.io/almalinuxorg/almalinux:10

Or, from a Dockerfile:
FROM --platform=linux/amd64/v2 quay.io/almalinuxorg/almalinux:10

Notice that these don't (currently?) work with Docker's container repository, so Red Hat's it is.
