[libvirt] fdisk still shows the "/dev/sdb" partitions even after the removal of scsi disk

Hi, I have filed a bug "fdisk still shows the "/dev/sdb" partitions even after the removal of scsi disk" for the upstream kernel. Bug link: https://bugs.launchpad.net/qemu/+bug/1190525 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 Thanks, Chandrashekar
