This patch singles out pc-1.0 just because it used to be the default in
Ubuntu 12.04. So basically it's making upstream carry the burden of a
decision of the Ubuntu folks. It's understandable that Alex disagrees
with the decision, but nevertheless it's not something that upstream
should agree with.
Also, another horse that has left the barn: it's already too late to
apply this patch to upstream Ubuntu. If you do that, any machine
created with 12.04 and reused with 14.04 will fail to migrate to another
14.04 machine that includes this patch, as I understand it.
So as things stand, I don't see a reason to apply this patch upstream.
Well, Ubuntu (Serge I think) said in the Ubuntu bug report he'd
be quite willing to break migration of pc-1.0 machine types
from 14.04 to 14.04 because that machine type isn't the default
anyway on 14.04.
But that isn't the point, as the patch (as a whole) doesn't
break anything - it merely gives the possibility to import
pc-1.0 machines from qemu-kvm. That's useful even if you
build qemu from source every time.
Or were you just arguing against the ./configure option?
