Presumably when you say "libvirt" here, you mean the libvirt library
itself, rather than the Nova libvirt driver.

If you want libvirt to understand new attributes, then you need to
write a patch for libvirt that updates its XML parsers / generator,
updates its RNG schema, the schema docs, and finally the code to
convert from XML to QEMU command line arguments (or equivalent
for non-QEMU based virt drivers in libvirt). If you need help in
adding features to core libvirt it is best to ask on the main libvirt
mailing lists
