I've been having crashes with the same assertion message, when trying to run Windows 10 ARM under a VM. But I finally figured out that what's actually crashing it is not the fact that it's Windows, it's the fact that I was attaching the virtual drive via virtual USB.

If I do the same thing to an Ubuntu ARM64 guest, it *also* crashes.

qemu-system-aarch64: ../../block/aio_task.c:64: aio_task_pool_wait_one: Assertion `qemu_coroutine_self() == pool->main_co' failed

With the RISC-V guest, does your crash change if you change the type of attachment that's used for the virtual disk?

Also, I tried enabling core dumps in libvirt, but it didn't seem to dump cores to apport. Enabling core dumps would be useful for issues like this.
