Thanks a lot to Noah for reviewing and merging the MR. Trixie cloud 
images are now built for riscv64 [1].

To run the image with QEMU, you need to use to a UEFI firmware, the 
easiest is probably to use U-Boot (from the u-boot-qemu package), the 
alternative being to use EDK-2.

Here is a way to run the image with a graphical console:

qemu-system-riscv64 \
    -kernel /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin \
    -M virt \
    -m 1G \
    -smp 2 \
    -device virtio-net-device,netdev=usernet \
    -netdev user,id=usernet \
    -drive file=debian-13-nocloud-riscv64-daily-20250729-2188.qcow2,format=qcow2 \
    -device bochs-display \
    -device qemu-xhci -device usb-kbd -device usb-mouse

And with a serial console:

qemu-system-riscv64 \
    -kernel /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin \
    -M virt \
    -m 1G \
    -smp 2 \
    -device virtio-net-device,netdev=usernet \
    -netdev user,id=usernet \
    -drive file=debian-13-nocloud-riscv64-daily-20250729-2188.qcow2,format=qcow2 \
    -nographic
