Some background to my questions. I am currently investigating the port
on the Veritas volume manager and filesystem to the xen architecture.
The logical approach is to use the volume manager in Dom0 and the
filesystem in DomU and this can currently be done using the vbd driver.
However the filesystem in DomU then just sees the volume as a disk
partition and is unable to make use of a number of private functions
supplied by the volume manager to provide the filesystem with additional
functionality and performance. Therefore I am investigating the
implementation of a virtual volume driver that would provide those
private functions in DomU. There is no need for this driver to be
included in the xen source, hence the need for a loadable driver.
Considering that Xen drivers will end up in the Linux tree in the
(hopefully) not too distant future, and the Linux community's well
known aversion for out of tree modules, please consider submitting
it. It will make your life a whole lot easier in the long run.

Thanks for the suggestion. I'll certainly consider submitting it as it
clearly will have to be a GPL module, but as the associated filesystem
and volume manager are not in the tree I'd like to have the option of
having it out of the tree.
