Qemu is still incomplete to fully support parisc. Mostly hardware-emulation is missing.

Nevertheless, emulating a Linux system is already possible.


HOW TO QUICK-START AND RUN A PRECOMPILED QEMU:


  1. Download statically compiled qemu: ftp://parisc.parisc-linux.org/qemu/qemu.tgz (just 8MB)
  2. Untar the tar-gz file in some directory
  3. Download a debian install CD into the same directory, e.g. http://ftp.nz.parisc-linux.org/debian-cd/9.3/debian-9.3-hppa-CD-1.iso
  4. Run qemu (either via the provided startme.sh script), or manually:

./qemu-system-hppa -drive file=hdd.img,discard=unmap -accel tcg,thread=multi -smp cpus=2 -drive file=debian-9.3-hppa-CD-1.iso,media=cdrom -m 3600M -boot menu=off,order=d -serial mon:stdio -device e1000,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5555-:22



HOW TO BUILD FROM SOURCE:


Richard Hendersons qemu git tree:

Helge Deller SeaBIOS git tree:

Howto:

  1. checkout out trees above, configure and build
  2. copy (or symlink) the parisc firmware file "out/hppa-firmware.img" from seabios into the qemu "pc-bios/" directory
  3. qemu-img create -f qcow2 hdd.img 30G
  4. download install image: https://cdimage.debian.org/cdimage/ports/, e.g. https://cdimage.debian.org/cdimage/ports/9.0/hppa/iso-cd/debian-9.0-hppa-NETINST-1.iso
  5. ./hppa-softmmu/qemu-system-hppa -drive file=hdd.img -drive file=debian-9.0-hppa-NETINST-1.iso,media=cdrom -boot order=d -nographic -serial mon:stdio


qemu options:

  • -accel tcg,thread=multi - always use this to enable parallel tcg (otherwise all guest CPUs run on one host CPU)
  • -smp cpus=4 - define number of CPUs in the guest (maximum CPUs: 32)
  • -boot menu=on - Firmware: enable interactive mode (boot prompt)
  • -boot order=c - Firmware: Boot from hard disc
  • -boot order=d - Firmware: Boot from CD/DVD
  • -serial mon:stdio use serial console
  • -nographic - no graphics device
  • -device VGA - provide PCI VGA graphic card

Examples:

  • ./hppa-softmmu/qemu-system-hppa -drive file=hdd.img -drive file=debian-8.0-hppa-NETINST-1.iso,media=cdrom -nographic -serial mon:stdio
  • ./hppa-softmmu/qemu-system-hppa -cdrom debian-8.0-hppa-NETINST-1.iso -nographic -serial mon:stdio
  • ./hppa-softmmu/qemu-system-hppa -device virtio-scsi-pci,id=scsi -drive file=debian-8.0-hppa-NETINST-1.iso,if=scsi,media=cdrom,bus=0 -nographic -serial mon:stdio
  • ./hppa-softmmu/qemu-system-hppa -device lsi53c895a,id=scsi -drive file=debian-8.0-hppa-NETINST-1.iso,if=scsi,media=cdrom,bus=0 -nographic -serial mon:stdio

How to run:

  • ./hppa-softmmu/qemu-system-hppa -drive file=hdd.img -drive file=debian-8.0-hppa-NETINST-1.iso,media=cdrom -boot menu=on -serial mon:stdio
