The virtio-scsi command virtqueues run during hotplug. This creates the
possibility of race conditions since the guest can submit commands while the
monitor is performing hotplug.
See Patch 2 for a fix for the ->reset() vs event race condition that Zhengui Li
encountered.
Zhengui Li: Sorry it took me so long to look into this. Please let me know if
this fixes the issue you are seeing. Thanks!
