[Qemu-devel] qemu high cpu load when -monitor stdio and fifo is used |

Please help me.!
I'm trying to send command to the qemu monitor via a FIFO device in
order to stop,start and save the vm state in a file from another
process .
The script I'm using is the following:
#!/bin/bash
mkfifo /tmp/serin
qemu -boot c -cdrom win2000.iso -hda win2000s.img -m 256
-localtime -snapshot -nographic -serial null -monitor stdio -n
./qemu-ifup < /tmp/serin &
exit
When this script is started the emulator doesn't start.
I have to send the following command via /tmp/serin
echo "start " > /tmp/serin
After that, the emulator runs fine but the cpu load is very high (near
99%) also if i send the "stop" command : echo "stop" > /tmp/serin
the emulation get stopped but the cpu load remain high.
The emulated system is windows 2000 server
Any help is really appreciated
Sebastiano
