Hi Dave,

Sorry for replying late.

Hi,

i think i mostly finished my sr driver for our product.
you can find it at
        http://vastsky.svn.sourceforge.net/viewvc/vastsky/trunk/xcp/

Cool!

How would you like the code to be incorporated? Would it be best to take 
infrequent tarball snapshots or to 'svn up' from your repo on every build?

Looking at the driver code I think the only major thing we have to sort out is 
the multipath handling. XCP handles multipath in a slightly different way to 
standard CentOS. 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

Cheers,
Dave


can someone please review the code and consider to include it in
the xcp distribution?  thanks.
