Hosts/Cluster Arch Types Allocation
Since CloudStack 4.20.0, it is possible to add AMD 64 bits and ARM 64 bits clusters (and hosts). A single zone can contain clusters (and hosts) of different arch types (multi-arch zones).
When a multi-arch zone is selected for VM deployment, CloudStack allows the users to filter the templates/ISOs by their arch type.
Once a template/ISO is selected, only the clusters (and hosts) matching the arch type will be considered for the VM allocation
