[Xen-devel] [PATCH][IOEMU] Fix to Allow blktap to be able to be booted as system volume for PV-on-HVM.

["Kasai Takanori" <kasai.takanori@xxxxxxxxxxxxxx>]

Hi All,

I sent the patch to allow blktap to be able to booted as system bolume for 
PV-on-HVM.
However, there was a problem that hdN and xvdN were not able to be specified at
the same time.

I made the patch to correct it as follows.
- Whether hdN is defined first is checked.
- If hdN is defined, xvdN is not replaced with hdN.
