Hello, everyone

After executing the "savevm" command, the QEMU process is hanging.
But in the v1.4.0, it's no problem.

Host OS: Fedora 17 x86_64
Qemu: the latest(2013-04-01)
Quest OS: WinXP

1) Use the following command to start the VM:
    qemu-kvm -enable-kvm -name winxp -M pc-0.15 -m 1024 -smp 2 -boot c -device 
piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 
    -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -drive 
file=/home/test/winxp.qcow2,if=virtio,index=0,format=qcow2 
    -net nic,model=virtio,macaddr=52:54:00:05:11:12 -monitor stdio -chardev 
spicevmc,id=charchannel0,name=vdagent 
    -device 
virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0
 -chardev pty,id=charchannel1 
    -device 
virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=arbitrary.virtio.serial.port.name
 -device usb-tablet,id=input0 
    -spice 
port=3001,addr=186.100.8.131,disable-ticketing,plaintext-channel=main,plaintext-channel=playback,plaintext-channel=record,image-compression=auto_glz
 
    -vga qxl -global qxl-vga.vram_size=67108864 -device 
AC97,id=sound0,bus=pci.0,addr=0x4
2) Execute the "savevm" command in the qemu monitor.
   After a long time (>20minute), the qemu process is still hanging.

Who can give me some advice?

Best Regards,
 
Jeremy Liu
