[Xen-devel] [PATCH v2] xend: Unlink VDI instances and VBD instances

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi Keir,

VBD information in xend does not have a VDI value if XenAPI mode 
is invalid.
A new patch confirms the VDI value is valid.  So, the new patch 
cuts off VDI->VBD links if the VDI value is valid.

Signed-off-by: Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>

Best regards,
 Kan
