Not a bug, this is just how hosts are numbered in Linux. Note that you do not need to delete and readd the virtio-scsi-pci device, only the scsi-hd device. If you do so, the scsi-hd device will reside on host3.

If you do so, the scsi-hd device will reside on > host3. yes, i test it as your indication. if do not delete the virtio-scsi-pci controller, noly remove the scsi-hd device, the index of the SCSI controller and partition table for the disk can be sequential. But why cann't delete the virtio-scsi-pci controller? if hot-remove SCSI controller, then hot-add it again, the index of SCSI controller was not decremented after hot-plug it again, while the partition table can decrement to the right number. Paolo, could you help explain it here & thx. Best Regards. sluo |
