Hi,

In the case of disk hot-plug, we need a xml like this :

<disk type="file" device="disk">
  <driver name="qemu" type="qcow2"/>
  <source file="/root/vda.qcow2"/>
  <target dev="vda" bus="virtio"/>
  <address type='pci' domain='0x0000' bus='1' slot='20' function='0x0'/>
</disk>

For now, go-xml does not support DomainDisk marshal.

Any good idea ?
