ovfconverter unable to read config.ini #850

[ganeti 2.10.4 from wheezy-backports, debian wheezy]

Even after making a raw block export (-o snf-image), ovfconverter fails with 
the following error:

# /usr/lib/ganeti/tools/ovfconverter export --format=vmdk

As far as I can tell, ovfconverter is looking for a setting "memory" in an ini 
section "[backend]", but no such section exists in config.ini.

However test/data/ovfdata/config.ini *does* have a "[backend]" section. 
Possibly the config.ini format has changed but the test data and the 
ovfconverter have not been updated?

This does suggest that ovfconverter is not being used by anybody, at least for 
export :-(

Correction: the '[backend]' section exists but the 'memory' setting doesn't.

However if I use gnt-instance info I see:
...
  Back-end parameters:
    always_failover: default (False)
    auto_balance: default (True)
    maxmem: default (128)
    memory: default (128)
    minmem: default (128)
    spindle_use: default (1)
    vcpus: default (1)
...

The gnt-instance "memory" value is added explicitly [lib/client/gnt_instance.py]

  # deprecated "memory" value, kept for one version for compatibility
  # TODO(ganeti 2.7) remove.
  be_actual = copy.deepcopy(instance["be_actual"])
  be_actual["memory"] = be_actual[constants.BE_MAXMEM]

Maybe minmem and maxmem should map to rasd:Reservation and rasd:Limit 
respectively? In that case can you just omit rasd:VirtualQuantity? (The schema 
appears to allow this, but not sure if other implementations would be happy)
