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

Have you tried qemu.git/master?
Once you find out which version works and which is broken, you can use
git-bisect(1) to find the commit that broke "savevm".

Hi, Stefan
Thanks for your reply.
I have test the latest version of qemu.git/master(commit:9196dd411d580c27f85daa209ff9a501d719ebc0,2013-04-06).
But, this problem still exists.
This problem appears after the commit(500f0061d628b52220038939728f0d7aee634468, Use qemu_put_buffer_async for guest memory pages).
But I'm not sure why this commit cause this problem.
I simplified the qemu-kvm command to the below:
qemu-system-x86_64 --enable-kvm -m 1024 -smp 2 -boot c -drive file=/home/test/winxp.qcow2,
if=virtio,index=0,format=qcow2 -monitor stdio -vnc 186.100.8.131:1
Best Regards,
Jeremy Liu
