Your os system is installed on virtio-blk device (according to your screen shot)? Update: If I hotplug a disk to the existing virtio-scsi and do system_reset. No issue is observed. I tested both upstream and qemu-kvm-1.5.2-2.el7. I did not hit the issue. Consider the bug report is half year old, Can you retest with latest rhel7 package. Thanks.
