This patch breaks starting qemu for me on 32-bit x86 with the following assert:
qemu-system-x86_64: savevm.c:1129: register_savevm_live: Assertion
`!se->compat || se->instance_id == 0' failed.
my qemu command line is:
/opt/qemu/bin/qemu-system-x86_64 \
-m 1500 \
-enable-kvm \
-drive if=none,file=/dev/vg01/qemu-root,cache=none,aio=threads,id=root \
-drive if=none,file=/dev/vg01/qemu-data,cache=none,aio=threads,id=test \
-drive if=none,file=/home/test1.img,cache=none,id=scratch \
-device virtio-blk-pci,drive=root \
-device virtio-blk-pci,drive=test \
-device virtio-blk-pci,drive=scratch \
-append "root=/dev/vda console=tty0 console=ttyS0,38400n8" \
-monitor tcp:127.0.0.1:31337,server,nowait \
-kernel arch/x86/boot/bzImage \
-nographic
btw, I can't find a patch for that commit anywhere in the qemu-devel
archives. Did it get reviewed anywhere at all?
