Bug detailed description:
After qemu is upgraded to 0.9, it could support SATA disk emulation. However,
the feature is not stable. I attach an image file or a partition and config it
as a sata disk, and I can see that it shows as /dev/sda1 in the guest. Then I
mount /dev/sda1, and copy some files to it. The guest will hang after a few
minutes, or the cp command will fail and never reture.

Reproduce steps:
1. attach an image file as the second disk in the config file, and set it as
2. Create the guest

Current result:

Expected result:
