Anthony,

Thanks for your reply!

I made some modifications to libvirt last night, to have it not send
in the two parameters you mentioned (script= and ifname=) and indeed,
I was able to create the VM without any modifications to kvm.  I am
still having some other issues with migration, but I believe these to
also be related to the way libvirt is accessing kvm and will try to
look into these separately.  I see that there are some changes with
regard to the qemu parameters since the last libvirt release, so I'll
see if the development version fixes these issues.
