If you need to reproduce the installation hang I suggest using qemu
-snapshot or qemu -drive ...,snapshot=on. These options prevent changes
made by the guest to the disk image from being permanent.
Once you terminate QEMU the changes will be gone and your disk image
will be unchanged - useful for repeatedly testing these types of issues!
