Comment # 8 on bug 1200564 from Michal Suchanek

You probably want

- qemu commandline and version
- kernel version of host and guest (the newer the better)
- the way to observe the corruption

like if you create a zero filled disk, overwrite it with /dev/urandom, shut
down the machine gracefully, and look at the disk do you still see zeroes?

or if you create disk filled with /dev/urandom, write zero to it, shutdown
machine do you see non-zero blocks?

or write something in the VM, read back something else?
