[Qemu-devel] iotest 194 fails on vhdx

[Alexey Kardashevskiy]

Hi!

The latest QEMU fails on:
tests/qemu-iotests/check -vhdx 194


/home/aik/pbuild/qemu-aikhostos2-ppc64-softmmu-debug-build/ppc64-softmmu/qemu-system-ppc64
\
 -chardev socket,id=mon,path=/home/aik/qemudest-monitor.sock \
 -mon chardev=mon,mode=control \
 -display none \
 -vga none \
 -machine accel=qtest \
 -nodefaults \
 -incoming unix:/home/aik/qemu-migration.sock \
 -drive if=virtio,id=drive0,file=/home/aik/dest.img,format=vhdx,cache=writeback


GDB says it is assert(!(bs->open_flags & BDRV_O_INACTIVE)). The very same
test passes with a qcow2 image. Does it look any familiar to anyone? Where
to start digging from? Thanks.
