For the record.... I managed to get this to work in the end and it
appeared to be down to the whitespace.... creating a string
representation of the XML DOM that looked like:
<domain type="kvm">
<name>testserver2002</name>
<memory>512</memory>
<vcpu>1</vcpu>
<os>
<type arch="x86_64" machine="pc-0.11">hvm</type>
<boot dev="hd"/>
</os>
<features>
<acpi/>
<apic/>
<pae/>
</features>
<clock offset="utc"/>
<devices>
<emulator>/usr/libexec/qemu-kvm</emulator>
<disk type="file" device="cdrom">
<driver name="qemu" type="raw"/>
<source file="/var/lib/libvirt/images/ISOs/centos5.5-ks.iso"/>
<target dev="hdc" bus="ide"/>
<readonly/>
</disk>
<interface type="network">
<source network="default"/>
<model type="virtio"/>
</interface>
<input type="mouse" bus="ps2"/>
<graphics type="vnc" port="-1" autoport="yes"/>
</devices>
</domain>
Allowed the domain to be created....
