So I'm now told I'm holding it wrong, and I need to boot with UEFI. Which is *>2000* ages of specification, plus a load more reading on how to configure UEFI. And UEFI isn't even mentioned in the qemu docs for the machine I'm emulating (risc-v virt), so I don't even know if it's available.
How the hell is a human being meant to be able to understand all this stuff to actually use the hardware?
I've been trying to write a very basic OS. The goal: to make the thing understandable to one person. But modern hardware and systems... *sigh*.
I'm booting with U-Boot, because I couldn't get qemu to boot the kernel directly. Now I need some information from the device tree, but booting with u-boot's `bootelf` doesn't pass the DT to the kernel it's starting.

#虚拟化
突然发现很喜欢这种边讲边输入命令的视频
视频顺序是kvm qemu libvirtd
kvm kernel VM 是Linux的一个模块
qemu发音为kī mǔ 模拟
libvirt 虚拟化管理工具包，之前在cockpit的virtual machine管理用到了，libvirtd为守护进程

EDIT: Solved! Thank you to @penguin42 for the guidance. I now have an aarch64 VM running Debian and "host-only" networking so I can SSH in easily. My next challenge will be to do the same with Arch or Alpine, and get serial over TCP or a UNIX socket working.
#HIVEMIND: Does anyone have any tips on running ARM VMs on AMD64? Preferably both 32 and 64-bit.
I've got a few apps (#plptools, the new #SIBOSDK) that I'd like to be able to compile and test while on-the-go.
I'm guessing something like #qemu would do the job, but I don't know where to begin.
