I think this is a rather ill-defined concept to be adding the guest XML,
since there are many checks done for assignment, and this is only impacting
one of them. Whether to allow a device beind a non-ACS enable switch to be
used in a VM has implications beyond just the one VM it is assigned to. Thus
is strikes me that the decision as to whether to allow use of devices behind
non-ACS switches should be a host level attribute. eg a config item in the
/etc/qemu/qemu.conf file
Regards,
Daniel
