After having run qemu with the -snapshot option, I tried to run another
time without the -snapshot option, only to see that qemu reported that
the device is empty.
Each time running again with that option, brings back a working system,
but never again without that option.
I like to know what went wrong and how I can use qemu again without that
option.
I am using qemu-2.0 and am using an image file.
Most likely the image file is incorrect in some way.
Try attaching it to a loopback device (losetup -P -f --show <file>)
and examining the image file to see if it's a correctly formatted disk
image.
Most likely, if it was damaged, it was not damaged by Qemu but by some
other action.
