Doc Text Cause:
Opening a qemu disk image from multiple processes at the same time (for example, attempting to take a snapshot of a qemu image while the guest is running) can lead to image corruption.

Consequence:
The qemu image becomes corrupted.

Fix:
Never use qemu-img to modify images in use by a running virtual machine or any other process; this may destroy the
image. Also, be aware that querying an image that is being modified by another process may encounter inconsistent state.

Result:
Image corruption does not occur.

Using qemu-img to modify an image that is in use can corrupt the image

Opening a QEMU disk image from multiple processes at the same time, for example by attempting to take a snapshot of a QEMU image while the guest is running, in some cases corrupts the image. To avoid this problem, never use the qemu-img utility to modify images in use by a running virtual machine or any other process. In addition, be aware that querying an image that is being modified by another process may encounter inconsistent state problems. This update also adds the above admonition to the qemu-img(1) man page.
