[pve-devel] disable-efi-enable-pxe-roms.patch break livemigration from old qemu guest without pxe

I have found this qemu mailing thread

[PATCH v3 0/8] acpi: make ROMs resizeable
https://lists.gnu.org/archive/html/qemu-devel/2015-01/msg00570.html

This seem to be include in qemu 2.3 and fix the migration when rom size is different.
(that could explain why it's working for you for qemu 2.4 pxe-> qemu 2.4 efi, and not for me on qemu 2.2 pxe -> qemu 2.4 efi.)

Attached is my previous try, but I got strange kvm crashes and it did not work.
