Hello everybody,
I have created a patch for blkif.py to support only hd[a-t] devices from 
1 to 63. There was missing $ sign at the end of the regular expression 
and therefore even hda100 was able to be attached but not working 
correctly. Anyway hda989898 was able to be mounted but it crashed guest 
kernel. This patch solves this issue...
