I just want to summarize
XML for OpenVZ will looks like

<name>209</name>
<uuid>8dea22b31d52d8f32516782e98ab8fa0</uuid>
<devices>
<filesystem type="template">
<source name="fedora-core-5-i386" />
THis will also get an element:
<target dir="/"/>
<quota type="size"
max="10000"/>
<quota type="inodes" max="200000"/>
</filesystem>
<interface type='bridge'> //for bridge
<source bridge='eth10'/>
<mac address='00:16:3e:5d:c7:9e'/>
</interface>
This is good.
<interface type='bridge'> //for NAT
<source bridge='eth11'/>
<target type='network'>
<source network='default'/>
</target>
</interface>
I think you mis-understood how I described this previously. The libvirt
NAT networking works like this:
<interface type='network'>
<source network='default'/>
<mac address="11:22:33:44:55:66"/>
</interface>
<interface type='network'> //for
phisical device
<host class='network' dev='eth1'/>
</interface>
I'm not sure about this - I think I'd still like host device passthough
to be an explicit type of device:
<host class='network' subsys='pci'>
<source name='eth0'/>
<address domain="0000" bus="00" slot="1f"
function="3"/>
</host>
With either the 'class' or 'subsys' properties being required.
Given one, libvirt can fill in the other as needed. If 'class'
is provided, then the <source> element should be used too. If
'subsys' is provided, then <address> provides the hardware
device address. This information will all be available directly
from the host device enumeration APIs, so we'll want to have a
clearly defined mapping between the domain XML for a host device
and the host device XML

<interface type='route'> //for routing
network
<mac address='00:16:3e:34:21:9e'/>
<ip address="192.168.122.1" />
<ip address="192.168.122.15" />
</interface>
This is basically the generic type='ethernet' that we already have,
but with a few more properties available, so I don't thing there's
need for a new type='route'
