It's not a good path to follow.  Tomorrow we'll need to load 300MB 
initrds and we'll have to rework this yet again.  Meanwhile the 
kernel and virtio support demand loading of any image size you'd 
want to use.

firmware is totally broken with respect to -M older FWIW.

Well, then this is adding to the brokenness.

fwcfg dma is going to have exactly one user, libguestfs. Much better to have libguestfs move to some other interface and improve are users-to-interfaces ratio.
You mean, only one class of users cares about the performance of loading 
an initrd.  However, you've also argued in other threads how important 
it is not to break libvirt even if it means we have to do silly things 
(like change help text).
So... why is it that libguestfs has to change itself and yet we should 
bend over backwards so libvirt doesn't have to change itself?
