In addition to UAE to run real AmigaOS, there's AROS, which will run on PC hardware or hosted under Linux and a number of other OS's (AROS "boots" to the Workbench on my Linux laptop in a couple of seconds)
Any good guide on getting started with hosted AROS on Linux (Arm64 or x86_64)? I've been able to get to so far was building, being able to run but just getting an unresponsive process that did nothing (didn't debug further, but there was no high CPU utilization), but I could have missed a crucial step or have used a bad revision of the codebase.
It's been years since I built it, and then it just worked, though I think you're less likely to run into problems if you do a 32 bit build (it's not like any of the applications running in it are going to need a larger address space). But if you just want to play with it, it's probably better to look at one of the distributions, like Icaros (I don't like all of the choices made with Icaros, but it's a good starting point to have something functional rather than just a near empty default setup - in particular it includes support for integrating 68k Amiga apps into the host system):
