Hi Christian:

I still couldn't reproduce the issue:

[marios@name deltacloud]$ curl -X POST -H "X-Deltacloud-Driver: opennebula" -H "X-Deltacloud-Provider: http://occi.c12g.com" -v -u "USER:PASS" http://localhost:3001/api/instances/2715/stop?format=xml

Having said that - I ran into another issue just trying to list instances:

[marios@name deltacloud]$ curl  -H "X-Deltacloud-Driver: opennebula" -H "X-Deltacloud-Provider: http://occi.c12g.com" -v -u "USER:PASS" http://localhost:3001/api/instances?format=xml

this seems to be related to the xml sent back by http://occi.c12g.com. The current opennebula driver was written for ON 3.2... looking at this thread http://mail-archives.apache.org/mod_mbox/deltacloud-dev/201206.mbox/%3C4FE7DB26.4040600@twgrid.org%3E - it seems there are some compatibility issues (following the thread it seems that http://occi.c12g.com may now be running v 3.6). 

So in general it seems some work is needed on the ON driver - I'll try and ping the ON guys who maintain the driver (and point them at this issue) to see if they have the time - otherwise I'll be looking at it asap. For now I'll leave the ticket open and unresolved.

many thanks for reporting this issue,

all the best, marios
