Rather than listen for asynchronous uevents, paths must be explicitly registered with multipathd -- see mpathutil.py for CLI-like commands.


Thank you for the comment, but could you elaborate on the issue?
[ what's wrong with automatic detection by multipathd? ]

I took a look at mpathutil.py, but I couldn't figure out what you mean.
I think I'm missing how XCP uses multipath, so I'd appreciate your comment.

As we added Eucalyptus EBS support for vastsky, now our code for XCP is at:
http://vastsky.svn.sourceforge.net/viewvc/vastsky/trunk/drivers/xcp/

Best,
Tomoe
