What Went Wrong
What was I trying to do?
Set the boot order for a block device in a newly define VM
 
What was the expected outcome?
The USB device would be listed first
 ++ 
What actually happened?
The USB device is not listed first
 
Steps to Reproduce
1) ** Append this XML to a file
<disk type="block">
  <target dev="sda" bus="usb" />
  <boot order="1" />
  <source dev="/dev/sdc" />
</disk>
2) virsh define test.xml
3) virsh start --console test-vm
4) Press "Ctrl+[" during boot
5) Navigate "Boot Maintenance Manager" > "Boot Options" > "Change Boot Order"
6) Observe the listed boot order
 
How Reproducible
Intermittent. Around 1 out of every 3 times the VM is defined
