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".

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 > Re: [Qemu-devel] After executing "savevm", the QEMU process is > hanging > > On Mon, Apr 01, 2013 at 11:45:13AM +0000, Liuji (Jeremy) wrote: > > 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,na > me=com.redhat.spice.0 -chardev pty,id=charchannel1 > > -device > virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,na > me=arbitrary.virtio.serial.port.name -device usb-tablet,id=input0 > > -spice > port=3001,addr=186.100.8.131,disable-ticketing,plaintext-channel=main,plaint > ext-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? > > 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". > > Stefan ^ permalink raw reply [flat|nested] 4+ messages in thread
