Comment 10 for bug 923552

Hm, that's not what your most recent partman log indicates. I couldn't reproduce this in an alternate amd64 installation with a blank disk.

Since you can reproduce this in a VM, though, it should be a matter of sufficiently exact instructions, so ... Could I have exact directions on how you're starting qemu, including the qemu-img command that creates the disk, and the full qemu command line?
