H A Dq35.h04c7d8b8 Tue Nov 05 23:46:27 GMT 2013 Cole Robinson <crobinso@redhat.com> Fix pc migration from qemu <= 1.5

The following commit introduced a migration incompatibility:

commit 568f0690fd9aa4d39d84b04c1a5dbb53a915c3fe
Author: David Gibson <david@gibson.dropbear.id.au>
Date: Thu Jun 6 18:48:49 2013 +1000

pci: Replace pci_find_domain() with more general pci_root_bus_path()

The issue is that i440fx savevm idstr went from 0000:00:00.0/I440FX to
0000:00.0/I440FX. Unfortunately we are stuck with the breakage for
1.6 machine types.

Add a compat property to maintain the busted idstr for the 1.6 machine
types, but revert to the old style format for 1.7+, and <= 1.5.

Tested with migration from qemu 1.5, qemu 1.6, and qemu.git.
