Recently, Lubuntu powerpc becomes
stable and QEMU also becomes more
stable and compatible.
I found the report of
windows7 running on qemu / macport of OSX but it was reported to be still slow compared with VirtualPC for Mac 7.02
Then, I tried to run windows7 on QEMU2.0 / Lubuntu 14.04,1.
First, install qemu
apt-get install qemu
for sound emulation
apt-get install pulseaudio
Second, I converted
the previous disk image file installed windows7 starter (VPC for Mac 7) to qcow2 file.
qemu-img convert -f vpc -O qcow2
diskimage.vhd diskimage.qcow2
QEMU for PPC-linux can simulate at most 2047 MB RAM while VPC7 can do max. 512MB. QEMU can also be simulated multi-processor or -core, however windows7 starter supports only uniprocessor.
For sound emulation, "-soundhw ac97" option is needed and the
driver must be installed manually (
link).
qemu-system-i386 -m 2047 -smp 2,cores=2,sockets=1,threads=1 -localtime -vga std -soundhw ac97 -hda
diskimage.qcow2
Unfortunately, Windows7 on QEMU/Linux was slow as same as on
VPC7 with ramdisk.
Sounds also work ....but with severe delay.
On my several trials, a little speed-up could be observed when a disk image file was on high-speed USB drive (I used SANDISK EXTREME) than on the internal SATA HDD.
Other faster devices (SSD or RAM disk) may show better perfomance. I hope for the future updates, for expamle more RAM could be assign.
