Re: [libvirt] [PATCH libvirt 1/2] domain: add <forward> element for user mode networking

Yes, but let's avoid the code churn of needing to move it around in the struct and changing the parser/formatter - it's better for them to have it in the main structure from the beginning, and just restricted in the drivers where it is used (or not). That way, as the hypervisor drivers add support, only the driver code itself will need to be changed (and only for that particular driver).
