Description

What would you like to be added

We have hash for other arch than x86, but it's not tested, and some things are broken (download delegation, for instance, though I'm working on that).

Why is this needed

This should not actually be that hard to have multi-arch working properly, we just need to be a bit more mindful of using Ansible correctly (aka, consider that variable are host local, not constant across all hosts).

@ant31 Besides working on the kubevirt manifests in .gitlab-ci/kubevirt.yml, maybe we need some change on the test cluster at qemu level ? /help

Research direction
Examine the .gitlab ci/kubevirt.yml file to understand the current CI testing setup. Investigate the download delegation issue mentioned in the context of multi arch testing. Explore if QEMU emulation can be used for testing non x86 architectures. Review any existing multi arch support in the Kubespray codebase.
