Public bug reported:
In qemu 2.11 pc-i440fx-wily machine type is defined the following way by
the ubuntu patch:
101 +static void pc_wily_machine_options(MachineClass *m)
102 +{
103 + pc_i440fx_2_4_machine_options(m);
104 + pc_i440fx_machine_options(m);
105 + m->desc = "Ubuntu 15.04 PC (i440FX + PIIX, 1996)",
106 + m->default_display = "std";
107 +}
108 +
109 +DEFINE_I440FX_MACHINE(wily, "pc-i440fx-wily", pc_compat_2_3,
110 + pc_wily_machine_options);
In qemu 2.5, pc_compat_2_3 contained the following skip flags:
https://github.com/qemu/qemu/blob/v2.5.1.1/hw/i386/pc_piix.c#L304-L313
(skip configuration, skip section footers, and optional global state)
in qemu 2.11 those skips moved to pc_i440fx_2_3_machine_options:
https://github.com/qemu/qemu/blob/v2.11.2/hw/i386/pc_piix.c#L314-L320
https://github.com/qemu/qemu/blob/v2.11.2/hw/i386/pc_piix.c#L524-L529
https://github.com/qemu/qemu/blob/v2.11.2/include/hw/i386/pc.h#L573-L574
https://github.com/qemu/qemu/blob/v2.11.2/include/hw/compat.h#L193-L205
It happened in commits:
https://github.com/qemu/qemu/commit/71dd4c1a5672cafe9fb89abc83fe2a962f39ec42
https://github.com/qemu/qemu/commit/15c38503253bb9ba9b8efd17662069f69ca2b997
https://github.com/qemu/qemu/commit/5272298c48eb3a01c41a7822e6303d0a0a05f004
but pc_wily_machine_options still refers to
pc_i440fx_2_4_machine_options instead of pc_i440fx_2_3_machine_options,
migration config section is not being skipped on destination host and so
during migration the issue happens:
