virt-install uses libvirt API under the hood - fix one place, you fix
them all.

Yes, this is correct.  What exactly are you trying, and what is the
exact error message you are getting?

domxml-to-native is more of an upgrade help, and rather poorly
maintained.  It is there to help conversion of people starting qemu
command lines by hand into a rough draft of what it would take to get
libvirt to start a domain with the same features.

What version of qemu are you targetting?  Is it really a different fork
from upstream qemu, with different command line parameters?  If so, then
patches to src/qemu/qemu_command.c to issue the appropriate command line
when talking to the alternate qemu binary would be in order.
