I was objecting to making pc-1.0 special. There's nothing special in
Michael,
I'm about to post a nice simple v5 of this, but there are a couple of

I would rename "migration" to "compatibility" everywhere.

Isn't it quite a bit too late already? That's an old version by
now, and supporting migration from it is interesting for long-term
support distributions - like redhat for exa

Add a machine parameter qemu-kvm-migration for live migrate compatibility
with qemu-kvm version 1.0. Usage:
-machine pc-1.0,qemu-kvm-migration=on
This has three effects:
1. cirrus-vga.vgamem_mb defaults to 16 rather than 8
2. A type 2 piix4_pm record is interpreted as being type 3
3. A type 2
This patch series adds inbound migrate capability from qemu-kvm version
1.0. The main ideas are those set out in Cole Robinson's patch here:
http://pkgs.fedoraproject.org/cgit/qemu.git/tree/0001-Fix-migration-from-qemu-kvm.patch?h=f20
