If not, is there a way with one of the virt command line tools to create the XML (with the PCI addresses specified) so that I can process that XML and re-write the PCI addressing values?  Right now the only way I’ve been able to get that detailed XML file is to 1) virt-install and let the VM begin the boot process and then do a 2) virsh dumpxml and then 3) virsh destroy/undefine that VM, 4) modify the XML and then 5) virsh create ./modified.xml.  Is there a cleaner way to do this?
