Subject: hw/i386: disable smbus migration for xenfv
Git-commit: 0000000000000000000000000000000000000000
References: bsc#1159755
With commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea a new member
smbus_no_migration_support was added, and enabled in two places.
With commit 4ab2f2a8aabfea95cc53c64e13b3f67960b27fdf the vmstate_acpi
got new elements, which are conditionally filled. As a result, an
incoming migration expected smbus related data unless smbus migration
was disabled for a given MachineClass.
Since commit 7fccf2a06890e3bc3b30e29827ad3fb93fe88fea forgot to handle
xenfv, live migration to receiving hosts using qemu-4.0 and later is broken.
Therefore this patch must be applied to stable-4.x as well.

[BR: changed patch as obtained from qemu-devel mailing list to reference
xenfv, not xenpv, as Olaf indicated in followup email]
