Re: NetBSD on qemu-ppc

NetBSD/ofppc INSTALL kernel drops to db (after OpenBIOS console
printing lots of dma-alloc errors -21) with "/dev/console" not found.
It looks like PCI before cannot be configured, as there seem to be
problems with OpenBIOS/the firmware interface.

But hey, after your suggestion and more experiments, I tried /prep
again, and this time I had success:

A simple "qemu-system-ppc -nographic -M prep -hda disk.qcow2 -serial
pipe:ppc -kernel sysinst_com0.fs" can reach sysinst! sysinst_com0.fs
is taken from ftp.netbsd.org/pub/NetBSD/NetBSD-6.1/prep/installation/floppy/.
Console is redirected to the serial port, as the emulated VGA output
stays black.
generic_com0.fs, on the other hand, does not even reach NetBSD's
bootloader when called with the same arguments... No idea why.
The question is why the emulated IDE disk is not recognized. /prep
kernels seem to be quite limited regarding IDE controller support,
maybe I have to roll my own?

CPU usage on the host is also 100% when the guest is idle, but this
can be significantly reduced to ~0% by choosing another guest CPU
(like "-cpu 604", perhaps because of "powersave == 1").

Emulated PCI network cards (fxp, ne, pcn) give "couldn't map
interrupt", but I will try to get a working disk first...

Console output follows.
