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. Create 4GiB disk image: dd if/dev/zero ofdisk. The PC emulation works well and doesn't suffer from major incompatibility problems from qemu release to qemu release. kernel /rpi/vmlinuz-5.10.0-21-armmp-lpae \ The qemu project is really cool, and their goal is to support lots of computers, not just PCs. 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. Here is the command line invocation I have been using: qemu-system-arm -M xilinx-zynq-a9 -cpu cortex-a9 -nographic -kernel BUILDDIR/mm. 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. ![]() If you are looking to build just the SPARC system emulators from source yourself. Inspect the VM state without an external debugger. Qemu is used in the Linux Kernel Virtualization project named KVM. Freeze/unfreeze the Virtual Machine (VM) and save or restore its state from a disk file. You can use it to: Remove or insert removable media images (such as CD-ROM or floppies). While the raspi3b model works well, it is quite inefficient and its network speeds are really low because it emulates the USB-Ethernet adapter. The QEMU monitor is used to give complex commands to the QEMU emulator.
