"We'll also explore how you can install and run full Linux distributions on Apple silicon, and share how you can take advantage of Rosetta 2 to run x86-64 Linux binaries." That sounds like running Linux on bare metal...
But the title is "Create macOS or Linux virtual machines", which strongly suggests it's not bare metal.
But sometimes people write titles that only hit the biggest highlights, and the title may not mention everything that's in the video, so it's not impossible that it's Mac VMs, Linux VMs, and Linux bare metal.
