FWIW if you're running a more recent version of QEMU (>=3.1) then you can also
boot
from the virtio-blk-pci device directly instead of having to switch back to the
IDE
device after installation as you have done above. Should be something like:
qemu-system-sparc64 \
-m 4096 \
-device virtio-blk-pci,bus=pciB,drive=hd \
-drive
file=/home/brauner/.local/share/qemu/sparc64.img,format=raw,if=none,id=hd,bootindex=0
\
-net nic \
-net user \
-nographic
Note the removal of the legacy -boot argument and the addition of "bootindex=0"
to
the -drive argument.
ATB,
