Title:
  fdisk still shows the "/dev/sdb" partitions even after the removal of
  scsi disk

Status in QEMU:
  Incomplete

Bug description:
  RHEL guest shows the partittions even after the removal of scsi disk:
  fdisk still shows the "/dev/sdb" partitions even after the removal of scsi 
disk.

  Guest details:
  -------------------
  Kernel : 2.6.32-358

  
  Host Details :

  Upstream Kernel, Qemu, Libvirt and virt-manager
  ---------------------------------------------------------------------

  kernel version : 3.9.0+
  qemu version : QEMU emulator version 1.5.0
  libvirt version : 1.0.5
  virt-install : 0.600.3

  
  Steps to reproduce the issue:

  I. Add the SCSI disk through the virt-manager.
  2. Create the partition using fdisk  (eg: /dev/sbb) 
  3. Create a filesystem and format using mkfs.ext3 or mkfs.ext4 
  4. Remove the scsi disk  through the virt-manager. 
  5. Again run the fdisk /dev/sdb, the guests still shows the partition even 
after the removal of the disk.

  This issue is not seen with virt-io disk.

  This issue is also reproducible without even creating the partitions.

  Expected Result:

  The output of fdisk /dev/sd*  should not show the enties after the
  removal of scsi disks
