Long story short, virt-manager invokes virt-install which generates XML
string. This string (not yet saved onto disk, still just in memory) is
then passed to libvirt API virDomainDefineXML() which parses it, does
some sanity checking and finally formats it back and save it under
/etc/libvirt/qemu/$domain.xml.

Codewise, you want to be looking at qemuDomainDefineXMLFlags().
