[Bug 584143] Re: qemu fails to set hdd serial number

[Serge Hallyn]

** Description changed:

+ =========================================
+ SRU Justification:
+ 1. Impact: 'qemu -drive ...,serial=xyz' does not work
+ 2. How addressed: a patch from upstream fixes bug that sizeof was called on the wrong thing.
+ 3. patch: is in the description
+ 4. to reproduce: use '-drive ...,serial=xyz' option to qemu
+ 5. regression potential:  this only changes one line which called sizeof on the wrong thing, so should not impact any other code.
+ =========================================
+ 
  The -drive ...,serial=xyz option is broken, at least in 0.12.  See
  Debian bug#573439, http://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=573439 for details.
