Reviewing your config, you also list:

<qemu:commandline>
<qemu:arg value='-nographic'/>
<qemu:arg value='-nodefaults'/> 
</qemu:commandline> 

These are also unnecessary, libvirt already disables default devices
and if there are no <graphics> or <video> entries, -nographic or
equivalent is already done.

I don't think changing those are likely to help though, if you're still
getting the flood of DMAR faults, it seems like QEMU is still not
enabling the IGD quirks, or maybe your device behaves differently than
others we've seen.  Is there anything useful in the libvirt log file for
the domain?  I tried to make QEMU print errors for any cases where it
thinks legacy mode is being enabled. Thanks,
