That works for me.

What doesn't work is mounting that file/device READ/WRITE in one domU
to update the filesystem.  For that, I have to take down *all* domUs. 
Not good...

(When I try I get a vbd: error saying "already in use".)

(I know about caching and that I need eg. a cluster-aware filesystem
to do this.)

I've spent a couple of hours hunting through various Xen source files.
 There's a lot of Python functions that are only 3-5 lines long and
which does little else than calling the next function, which makes it
very hard to figure out what's going on :-/.

Could one of you devel guys please let me know where I need to go to
remove this silly limitation? :-)
