+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.
+
+|deploy-vm-arch-types.png|
+
+Once a template/ISO is selected, only the clusters (and hosts) matching the arch type will be considered for the VM allocation
