[libvirt-users] use of qemu-kvm --chardev pipe, id=X, path=... argument ?

[Jason Vas Dias]

Please can anyone enlighten me as to why linux qemu-kvm always
creates the console on my terminal, when I am trying to direct
all of its input and output to a pipe ?

I have created :
   $ mkfifo /tmp/el6x32{.in,.out,.monitor}
and use the command:
   $ /usr/libexec/qemu-kvm -M rhel6.4.0 -cpu n270 -smp 1 \
     -hda /home/rpmbuild/OEL6/img/OEL6_32.img \
     -kernel /home/rpmbuild/OEL6/boot/vmlinuz-2.6.39-400.215.14.el6uek.i686 \
     -initrd /home/rpmbuild/OEL6/boot/initramfs
2.6.39-400.215.14.el6uek.i686.img \
     -append 'root=/dev/sda rw selinux=0 enforcing=0 console=0' \
     -m 2048 -k en-gb -nographic -vga none -vnc none -enable-kvm \
     -chardev pipe,id=0,path=/tmp/el6x32 -monitor pipe:/tmp/el6x32.monitor

But this ends up with the kernel's console on qemu-kvm's  STDIO .

I actually want the console to be redirected to take input from
/tmp/el6x32.in and direct output to /tmp/el6x32.out -
I thought that was what the above '-chardev pipe,id=0,path=/tmp/el6x32'
should do if kernel boot params 'console=0' is also supplied ?
Why isn't this happening for me ? Anyone got a guest to read console input
from a pipe and direct console output to a pipe ? If so, how?

Thanks in advance for any replies, Jason.
