Hi Dmitry,
A bug that can lead to corruption was recently discovered in the vdi
image format code in QEMU.

The vdi image format code is only designed to work for
importing/exporting image files in qemu-img convert.  It is not suitable
for running guests and achieving good I/O performance.

I recommend using raw or qcow2 image files instead.
