The above runs a 32-bit kernel, if you were already running 64-bit Raspbian use the arm64 kernel instead and replace qemu-system-arm with qemu-system-aarch64. netdev tap,id=net0,ifname=tap0,script=no,downscript=no \ device virtio-scsi-device -device scsi-hd,drive=hd \ drive file=/rpi/root.img,format=raw,id=hd,if=none,media=disk \ Sudo dpkg -install linux-image-5.10.0-21-armmp-lpae_5.10.162-1_bĬopy out the kernel and initrd from /boot to the host, then run QEMU with something like this: qemu-system-arm \ First install a virtualization-capable kernel, Raspian doesn't provide one but the regular Debian ARM distro does: wget Getting it running is a bit more work but in the end not too complicated (more instructions here). It also supports arbitrary CPU counts and memory sizes.

I've had better success using the virt model which emulates a generic ARM system, but uses virtualization, rather than device emulation, which leads to lower CPU utilization on the host and much better I/O performance. It's also locked to 4 CPUs and 1 GB of memory.
While the raspi3b model works well, it is quite inefficient and its network speeds are really low because it emulates the USB-Ethernet adapter.
