Hi Erik,
Changes looks good so far. I did some basic testing with these patches.
I used above example snippet of hostdev element and it throws below
error. Add a '/' before '>' and after uuid in address line.
error: (domain_definition):74: Opening and ending tag mismatch: address
line 73 and source
</source>
---------------^
Failed. Try again? [y,n,i,f,?]:
Thanks,
Kirti
