[Libguestfs] [PATCH 7/7] v2v: add support for SUSE VMDP drivers
Cédric Bosdonnat

Tue Apr 5 11:47:33 UTC 2016
To add this support, the existing code searches for either the viostor
or the VMDP (Virtual Machine Driver Pack) files and updates the registry
accordingly.
Note that VMDP's block driver pvvxblk depends on the ballooning driver
pvvxbn.
