Cisco SD-Access home lab
Running Cisco SD-access in a home lab is difficult because of hardware requirements.
Running DNA center on a hypervisor requires at least ~60 vCPUs and 256GB of memory. That is a lot. You might be able to pull it off with older CPUs like the Xeon E5-2699v4 that offers 22 cores and 44 threads. It's a CPU from 2016 , so you could run into issues with modern hypervisors though.
You also need modern switches like the Catalyst 9300 with correct licensing. You can't emulate these using emulators like Cisco CML, EVE-NG, or GNS so you need physical hardware.
For now, you are better off using Cisco's hosted options like DevNet sandboxes. Cisco offers these for free.
