Metadata provides wrong size

[ko1N]

Metadata does not provide the proper ram size but only the size of the entire buffer after remapping.

It can be easily reproduced via:

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.provider :libvirt do |v|
    v.memory = 4096
    v.cpus = 2
    v.qemuargs :value => "-qmp"
    v.qemuargs :value => "unix:/tmp/vagrant-qmp.sock,server,nowait"
  end

  config.vm.box = "generic/ubuntu2010"
end

It fails with and without qmp to provide the proper metadata.

After some discussion with @h33p we think the best approach would be to rename the size field to max_address and eventually introduce a real_size field which could provide the usable size of the VM (which might help when doing compacted dumps)
