prettify rocks report host vm config

[lclementi]

Rocks report host vm config returns a very ugly xml.
Verify if you can prettify it with the following code before print it out:

---

import xml.dom.minidom

print xml.dom.minidom.parseString("zzz").toprettyxml()

I tried that... whitespace hell as described in [1]. Solution is not as good as..

# rocks report host vm config compute-0-0-0 | xmllint --format -
<?xml version="1.0"?>
<domain type="kvm">
  <name>compute-0-0-0</name>
  <os>
    <type>hvm</type>
    <boot dev="network"/>
    <boot dev="hd"/>
    <bootmenu enable="yes"/>
  </os>
  <memory>16777216</memory>
  <vcpu>16</vcpu>
  <cpu mode="host-passthrough"/>
...

I'll try to come up with something better.
