[Qemu-devel] [PULL 08/37] pc: make isapc and pc-0.10 to pc-0.13 have 1.7


From: Michael S. Tsirkin
Subject: [Qemu-devel] [PULL 08/37] pc: make isapc and pc-0.10 to pc-0.13 have 1.7.0 memory layout
Date: Sun, 29 Jun 2014 19:58:29 +0300

From: Don Slutz <address@hidden>

QEMU 2.0 changed memory layout for isapc and pc-0.10 to pc-0.13.
This prevents migration from QEMU 1.7.0 for these
machine types when -m 3.5G is specified.

Paolo Bonzini asked that:

    smbios_legacy_mode = true;
    has_reserved_memory = false;
    option_rom_has_mr = true;
    rom_file_has_mr = false;

also be done.
