  Installer version: 421
  Kernel: 4.4.0.4

  When trying to partition a KVM Virtual Disk, in my case based on a
  qcow2 image file, the partitioner is detecting the disk to be a DASD

  Virtual disk 1 (vda) - 10.7 GB Virtio Block Device
  >     #1    10.7 GB    f  ext4          /
  >            8.7 kB       FREE SPACE

  It then uses fdasd to partition it. This fails with the error:

  "fdasd: Unsupported disk type -- Disk geometry does not match a DASD
  device of type 3390."

  I have attached the syslog and partman log files, as well as my guest
  definition file.
