Open Stack

Hello,


Thank you for your answers, it's work pretty well :)
I can create/delete volume and attach them to a vm.  Next time i will
look for the format of the file (qcow2 prefered to raw)

Plz can you tell me/us when your patch will be release for snapshot ?
you base it on qcow2 file ?

I can move to the next step :)

Regards,
