Re: qemu-2.0 / spice crash

[Dominique Rodrigues <dominique.rodrigues@xxxxxxxxxxxxx>]

I did not uninstall spice agent to test that.

However, I am quite sure that there is a link with the SPICE driver. I have crashes after switching to fullscreen (and coming back or not to windowed screen). Usually, launching a video or an application (word 2013) is enough to crash the VM in only a few secondes.

If I never switch to fullscreen, the VM seems to keep stable, at least during more time.

Under SPICE_DEBUG_LEVEL=5, I got this message once (screen stayed freezed) :

(qemu) *** Error in `/usr/local/bin/qemu-system-x86_64': corrupted double-linked list: 0x00007f2e586fe490 ***

(not sure if there is a link with crash)

I also have crashes when I launch a Windows 7 VM with recent releases of qemu-kvm-2.0, while I don't have problems with qemu-kvm-1.7.1.

I use snapshot=off :

-drive file=${SYSTEM_DISK},if=virtio,media=disk,cache=writeback,aio=native,snapshot=off

and the following SPICE options :

-nographic \
-device qxl-vga \
-spice $SPICE_OPT \
-global qxl-vga.vram_size=$VGA_MEM \
-device virtio-serial-pci \
-soundhw hda \
-chardev spicevmc,id=vdagent,name=vdagent \
-device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
-balloon virtio \
-readconfig /opt/qemu_usb_redir/ich9-ehci-uhci.cfg \
-chardev spicevmc,name=usbredir,id=usbredirchardev1 \
-device usb-redir,chardev=usbredirchardev1,id=usbredirdev1  \
-chardev spicevmc,name=usbredir,id=usbredirchardev2 \
-device usb-redir,chardev=usbredirchardev2,id=usbredirdev2  \
-chardev spicevmc,name=usbredir,id=usbredirchardev3 \
-device usb-redir,chardev=usbredirchardev3,id=usbredirdev3 \
-monitor stdio


with SPICE_OPT=port=$SPICE_PORT,addr='localhost',password=$SPICE_PASS,image-compression=off,streaming-video=off,playback-compression=off

Hey

----- Original Message -----

Try with hard disk image snapshot=on.

Here is how I run qemu:
QEMU_AUDIO_DRV=spice
TMPDIR=/home/rick/qemu/hds
/usr/local/bin/qemu-system-x86_64 -cpu host -enable-kvm \
-m 1536 -name Win7Pro64 -localtime -no-fd-bootchk -smp cores=4 \
-pidfile /home/rick/qemu/hds/win7pro64.pid \
-drive file=/home/rick/qemu/hds/win7pro64.qed,if=virtio,index=0,snapshot=on \
-vga qxl \
-net nic,model=virtio -net user \
-device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 \
-chardev spicevmc,name=vdagent,id=vdagent \
-device
virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent,name=com.redhat.spice.0
\
-spice port=1247,disable-ticketing \
-monitor telnet:localhost:12471,server,nowait \
-drive if=none,id=cd,file=/dev/sg1 \
-device virtio-scsi-pci,id=scsi \
-device scsi-generic,drive=cd \
-balloon virtio \
-soundhw hda \
-device usb-ehci

Let me know if you still can't reproduce, then I'll run with spice debug
level 5.

I have been trying to get closer to your configuration, however windows is pretty picky on configuration changes and I hit BSOD.

Can you remove as much hw/arguments from your qemu command line? (for ex, is it still reproducable without soundhw, balloon, CD etc?)

In any case, I think the log could provide some hints.

thanks
