The code how it is today, is totally painful to read and keep.
To begin with, the code is duplicated with the option rom loading
code that linux_boot and vga are already using.

This patch introduces a "bootable" state in NICInfo structure,
that we can use to keep track of whether or not a given nic should
be bootable, avoiding the introduction of yet another global state.

With that in hands, we move the code in vl.c to hw/pc.c, and use
the already existing infra structure to load those option roms.

Howabout something like this:

commit eb8387cb0eda32a18880664eb5f0ca5c8bf05b45
Author: Riku Voipio <riku.voipio@iki.fi>
Date:   Thu Jun 18 22:44:31 2009 +0300
Subject: linux-user: include futex defines directly

Since some common distributions have broken linux/futex.h, stop
including it. Instead add the defines directly.

vga_screen_dump_blank() was not generating a valid PPM file: the width of the
image made no sense (why it was multiplied by sizeof(uint32_t)?), and there was
only one sample per pixel, instead of three.

Section 10.8.25 ("START/STOP UNIT Command") of SFF-8020i states that
if the device is locked we should refuse to eject if the device is
locked.

ASC_MEDIA_REMOVAL_PREVENTED is the appropriate return in this case.

In order to stop itself from ejecting the media it is running from,
Fedora's installer (anaconda) requires the CDROMEJECT ioctl() to fail
if the drive has been previously locked.

provide a monitor command to allow one to set the maximum
downtime he is willing to suffer during migration, in seconds.
"ms", "us", "ns" and "s" are accepted as modifiers.

This parameter will be used by ram_save_live() code to determine
a safe moment to enter stage 3

Currently, we're entering migration's stage 3 when
a treshold of 10 pages remain to be transferred in the system.

This has hurt some users. However, any proposed threshold is
arbitrary by nature, and would only shift the annoyance.

The proposal of this patch is to define a max_downtime variable,
which represents the maximum downtime a migration user is willing
to suffer. Then, based on the bandwidth of last iteration, we
calculate how much data we can transfer in such a window of time.

Whenever we reach that value (or lower), we know is safe to enter
stage3.

This has largely improved the situation for me.
On localhost migrations, where one would expect things to go as
quickly as me running away from the duty of writting software for
windows, a kernel compile was enough to get the migration stuck.

It takes 20 ~ 30 iterations now.

User space may only inject interrupts during kvm_arch_pre_run if
ready_for_interrupt_injection is set in kvm_run. But that field is
updated on exit from KVM_RUN, so we must ensure that we enter the
kernel after potentially queuing an interrupt, otherwise we risk to
loose one - like it happens with the current code against latest
kernel modules (since kvm-86) that started to queue only a single
interrupt.

Fix the problem by reordering kvm_cpu_exec.

Credits go to Gleb Natapov for analyzing the issue in details.

KVM-enabled QEMU will always report the vendor ID of the physical CPU it is
running on. Allow to override this if explicitly requested on the
command line. It will not suffice to name a CPU type (like -cpu phenom),
but you have to explicitly set the vendor: -cpu phenom,vendor=AuthenticAMD
