If no emulator is specified in the XML, libvirt will probe
a proper emulator from the driver's capabilities (See
virsh capabilities) by the requested OS, arch, and domain

The problem is virt-install doesn't has an option for you
to specify the emulator path. And thus libvirt will always
probe the emulator. So you might want to request virt-install
to add an option for the emulator in virt-tools list.
