Public bug reported:

In DataSourceOpenNebula, get_mask() and get_network() check keys of
CONTEXT Attributes, but doesn't check its values. If CONTEXT Attribute
key ETH0_MASK and/or ETH0_NETWORK have no value, their methods should
return default values, however actually return empty string('').

The problem occures when OpenNebula creats instances with Virtual
Network resources which CONTEXT Attribute of NETWORK_ADDRESS and/or
NETWORK_MASK is not defined.

It seems that get_ip() also has the same bug.

I attached a patch for this problem.
