Re: [Xen-devel] xen & MacVtap

hi Pasi

    Thanks for your reply, I think we know what you said, we have ever tried these ways.

     While you know, these ways are not stable enough for the engineering requirement, we have to apply many patches, and there are many restrictions for the Guest VM types.

     We need a more general & engineering  solution.

     Any way thanks for your reply.
