        !            17: Abstract: The blktap2 method provides a userland daemon to provide access to on disk files, arbitrated by the kernel. The NetBSD kernel lacks this support and currently disables blktap in xentools.

        !            19: Deliverables:
        !            20: 
        !            21: * blktap2 driver for /dev/blktapX
        !            22: * Tool support to be enabled in xentools
        !            23: * Enable access to various file formats (Qcow, VHD etc) , via the
        !            24: [ tap: ] disk specification.
        !            25: 
        !            26: Implementation:
        !            27: 
        !            28: The driver interacts with some areas of the kernel that are different
        !            29: from linux - eg: inter-domain page mapping, interdomain
        !            30: signalling. This may make it more challenging than a simple driver,
        !            31: especially with test/debug/performance risk.
        !            32: 
        !            33: Note: There's opportunity to compare notes with the FUSE/rump implementations.
