  Good point !

  My recollection of talking with James Bottomley is indeed that all
the special features are being migrated as part of the commonly agreed
upon set of kernel primitives put in the kernel for containers. So I hope
that this driver will indeed work based on those primitives and not
the Parallels specific extensions, as those may vanish sooner or later.

  What kernels do you support, only CentOS-6 modified ones ?
