Looks great.
Sorry for the delay. That mail somehow got lost in my inbox.
So in general, I used qemu-system-sparc64 which is available in Universe with either Debian or Ubuntu and that's what I've been using as host distro. So you need a
deb http://us.archive.ubuntu.com/ubuntu/ <release-name> universe deb-src http://us.archive.ubuntu.com/ubuntu/ <release-name> universe deb http://us.archive.ubuntu.com/ubuntu/ <release-name>-updates universe deb-src http://us.archive.ubuntu.com/ubuntu/ <release-name>-updates universe
int /etc/apt/sources.list
So after this, you should be able to install
apt install qemu-system-sparc
Now we need an image and believe it or not there's a guy who lives in Berlin too who builds Debian images for all crazy architectures. You can download them from:
https://cdimage.debian.org/cdimage/ports/
They're built quite frequently. Sometimes you get unlucky because a new kernel won't boot anymore then going a couple of months back usually helps. So for this experiment I downloaded:
https://cdimage.debian.org/cdimage/ports/9.0/sparc64/iso-cd/debian-9.0-sparc64-NETINST-1.iso
then I did:
cd .local/share/qemu truncate -s 15GB sparc64.img
And then to _install_:
qemu-system-sparc64 \ -m 4096 \ -device virtio-blk-pci,bus=pciB,drive=hd \ -drive file=/home/brauner/Downloads/debian-9.0-sparc64-NETINST-1.iso,format=raw,if=ide,bus=1,unit=0,media=cdrom,readonly=on \ -drive file=/home/brauner/.local/share/qemu/sparc64.img,format=raw,if=none,id=hd \ -boot order=d \ -net nic \ -net user \ -nographic \
Then the Debian install will run after it finishes you can boot with:
qemu-system-sparc64 \ -name debian-unstable-sparc64 -machine sun4u,accel=tcg,usb=off -m 4096 \ -smp 1,sockets=1,cores=1,threads=1 \ -uuid ccd8b5c2-b8e4-4d5e-af19-9322cd8e55bf -rtc base=utc -no-reboot -no-shutdown \ -boot strict=on \ -drive file=/home/brauner/.local/share/qemu/sparc64.img,if=none,id=drive-ide0-0-1,format=raw,cache=none,aio=native \ -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-1,id=ide0-0-1 \ -msg timestamp=on -nographic
If the install isn't setting up the repos right and you can't install stuff the correct url is: http://ftp.ports.debian.org/debian-ports/ to put into sources.list

Thank you, Dave! Christian
