Hi List,
Im trying to control a winxp installation process (esp. the text-mode
part) via pipe through kvm. Im using the git-version of kvm from
yesterday (2011-12-19), build with these parameters:
~/qemu-kvm$ ./configure --enable-sdl
~/qemu-kvm$ make
~/qemu-kvm$ sudo make install
What works:
1. Generating ~/.winpipe/path.{in,out}via mkdir .winpipe; mkfifo
.winpipe/path.in; mkfifo .winpipe/path.out
2. Creating emty image via qemu-img create win.img 20G
3. Starting kvm via: qemu-system-x86_64 -m 1G -hda win.img -cdrom
winxpsp3.iso -chardev pipe,id=mywinpipe,path=.winpipe/path
What doesn't:
1. Piping some text via echo "R" > .winpipe/path.in (i.e. for starting
repair console in winxp-textmode) doesnt have any effect
2. Reading from path.out via cat ~/.winpipe/path.out (nothing happens
except the vm ends, then the command "cat .winpipe/path.out" ends, too)
has no result, only waiting
3. There is no .pipe/ directory inside winxp, wether on C: nor on D:
(looked in via starting repair-console with "R")
Whats wrong?
Tfh!
Oliver

Are you sure that windows is using the serial device at all?
You're not emulating a keyboard there, you're emulating input from a
serial device.

HI Sasha,
Ive found a better solution:
It is possible to pipe the qemu-monitor:
qemu ... -monitor pipe:.winpipe/path
so Im able to send commands through the path.in pipe via
sendkey-kommand, i.e.
echo "sendkey r" > .winpipe/path.in
echo "sendkey d" > .winpipe/path.in
echo "sendkey shift-dot" > .winpipe/path.in
echo "sendkey ret" > .winpipe/path.in
Its not very komfortable, but does its job :-)
Tfh!
Regards,
Oliver
