This will avoid overwriting all of the configuration during executing
vmcreate function, which initially doesn't know anything about existing
data - it only knows about passed through command line parameters. Now
it should be fixed.
In boxpy_data section it is possible to specify another nic and its type
to be attached to the vm:
boxpy_data:
advanced:
nic2: intnet
nic3: hostonly
It's a stub for now, and only intnet will work by providing another nic,
which user should take care about providing configuration.
Currently specifying attributes of VM was done by using command options
during creation, or only required VM name for rebuilding (due to smart
way of storing information within VM definition).
Now, there is possibility for providing all the information using
special key "boxpy_data" in user-script, so that there is no need to
provide that information from command line.
All three ways are respected with following order:
- default, which are hard coded in defaults
- custom user script passed by --cloud-config (or stored in vm in case
of rebuild)
- information which is stored in VM definition (if exists - this only
affects "rebuild" command)
- and finally highest priority have parameters passed by command line.
