XenVbd - The Xen Paravitual Storage Class Driver for Windows

The XenVbd package consists of two single device drivers:

• xenvbd.sys is a STORPORT miniport driver which attaches to a virtual device created by XenBus and creates a child device for each VBD for the generic disk driver (disk.sys) to attach to. It is also a protocol driver for the blkif wire protocol (see include\xen\io\blkif.h).

• xencrsh.sys is a driver which provides the necessary code to write a crashdump out to the paravirtual backend in the event of a BugCheck.

Miscellaneous

For convenience the source repository includes some other scripts:

kdfiles.py

This generates two files called kdfiles32.txt and kdfiles64.txt which can be used as map files for the .kdfiles WinDBG command.

sdv.py

This runs Static Driver Verifier on the source.

clean.py

This removes any files not checked into the repository and not covered by the .gitignore file.

get_xen_headers.py

This will import any necessary headers from a given tag of that Xen repository at git://xenbits.xen.org/xen.git.
