The issue is that the XML does not contain the CPU model type, following is what is actually being passed.

https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L6337

This is the actual XML provided on an arm64 deploy (can be confirmed using "virsh cpu-compare file.xml" -

<cpu>
  <arch>aarch64</arch>
  <topology sockets="1" cores="48" threads="1"/>
</cpu>

more logs: https://pastebin.canonical.com/209211/

If you insert <model>anything</model> then cpu-compare works, e.g.

However, https://github.com/openstack/nova/blob/f94c728bdddc9d1d3e3ae5f8f34b0111b9168bc9/releasenotes/notes/aarch64-set-proper-cpu-mode-8455bad7d69dc6fd.yaml indicates that no host-model will be passed.
