[one-users] XML interface to open nebula

[Carlos Martín Sánchez]

Hi Bharath,

You can let the VMs get to data created externally using contextualization.
Take a look at the CONTEXT/FILES attribute of the VM template [1].

Alternatively, you could create a FS image, mount it, and store your data in
it. Then create a new DATABLOCK Image [2] [3] and make use of that Image in
your VMs [4].

Regards.
