Comment 3 for bug 1548411

It works if the disk is backed by / pass-through an actual DASD drive.
One can change partitioning table to msdos or gpt by using preseed keys in the paramfile.

However, msdos & gpt partitioning tables fail on the disks backed by / pass-through an actual DASD drive.

So at the moment, one cannot have a partition table that works in all configs, on all virtualisation types with support for automatic recipes throughout.

I believe this is actually an upstream bug in parted, and it should be able to created dasd partition tables on virtio hard-drives in KVM which are backed by simple qcow2 file.

Let me email further details.
