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.
