Xen currently uses a different BIOS (hvmloader + rombios) therefore the
Qemu acpi_piix4 implementation wouldn't work correctly with Xen.
We plan on fixing this properly but at the moment we are just adding a
new Xen specific acpi_piix4 implementation.
This patch is optional; without it the VM boots but it cannot shutdown
properly or go to S3.
What's the long term plan? Will Xen adopt SeaBIOS or will you adapt
your BIOS to cope with our ACPI implementation?
I think it shouldn't be too difficult to adapt our current BIOS, but
we'll need few xen specific hooks in acpi_piix4.
The price that we'll have to pay doing so is loosing live-migration
compatibility with older xen installations.
Does Xen migrate roms (like the BIOS) in such a way that the persist
after a reboot?
I noticed there was only one machine type defined. In our experience,
to preserve compatibility with migration, it's useful to have versioned
machine names. We also have some special machine parameters to support
compatibility with qdev.
How does Xen handle hvm migration machine model compatibility?
