Hi Craig, The simulator is a dummy hypervisor that essentially uses the database (MySQL) to simulate resources (such as hosts, VMs, disks etc) while using the same orchestration/business logic as would any hypervisor. The CloudStack kernel/plugin based orchestration architecture allows developers to build feature that are agnostic of hypervisors/storage to be developed using the Simulator.
For my blog, you can attempt all-in-a-single RasberryPi4 as long as you've got the 8GB model, with the 4GB model it's possible but such a setup will eat all the available memory pretty soon (running CloudStack mgmt server, agent, mysql and nfs all). The toy setup I've got at home has one 4GB-ram rpi4 for mgmt server and two 8GB-ram rpi4s for KVM hosts, I run Ceph on all three of them, and on the mgmt server I run NFS server and Ceph dashboard.

What's the difference between the simulator and a full install? Also on your blog is everything installed on one pi? I assume it is but wanted to check.
