Through virt-manager, After we removed a virtio-scsi controller which
virtual disks still attach to it, Libvirt will add a LSI scsi controller
for this guest automatically and trigger a lifecycle event, virt-manager
updates and shows this new scsi controller in details panel once it got
the lifecycle event.
It may confuse user that a LSI scsi controller occurs while one removes
the virtio-scsi controller.
This patch prevents removing a scsi controller if any disks attaching to
it.
