There patch protects vmstop_requested with a lock and introduces
qemu_system_vmstop_request_prepare.
Together with the new call to qemu_vmstop_requested in vm_start,
qemu_system_vmstop_request_prepare avoids a race where the VM could remain
stopped even though the iostatus of a block device has already been set
(for example).
qemu_system_vmstop_request_prepare however also lets the caller thread
delay observation of the state change until it has itself communicated
that change to the user. This delay avoids any possibility of a wrong
reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

As suffixes do not make sense for sPAPR's device tree and
there is no way to filter them out on the BusState::get_fw_dev_path()
level, let's add an ability for the external caller to specify
whether to apply suffixes or not.
We could handle suffixes in SLOF (ignored for now) but this would require
serious rework in the node opening code in SLOF, which has no obvious
benefit for the currently emulated sPAPR machine.

Some machine (like pseries) initialization code determines if it has
graphics according to vga_interface_type. In the original code,
vga_interface_type is evaluated to VGA_NONE even if a VGA is added
via '-device VGA'. It causes the machine not aware of the graphics
device configured. Add a new VGA device type to indicate that it has a
VGA device, which will be initialized in QOM device initialization.

Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME. If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).
Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME). The others are ignored.
"First one wins, subsequent ones get ignored silently" isn't nice. We
commonly let the last option win. Useful, because it lets you
-readconfig first, then selectively override with command line
options.
Clean up -smbios to work the common way. Accumulate the settings,
with later ones overwriting earlier ones. Put the result into fw_cfg
(no more useless duplicates).
Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

Currently Xen hvm s3 has a bug coming from the difference between
qemu-traditioanl and qemu-xen. For qemu-traditional, the way to
resume from hvm s3 is via 'xl trigger' command. However, for
qemu-xen, the way to resume from hvm s3 inherited from standard
qemu, i.e. via QMP, and it doesn't work under Xen.
The root cause is, for qemu-xen, 'xl trigger' command didn't reset
devices, while QMP didn't unpause hvm domain though they did qemu
system reset.
We have two qemu patches and one xl patch to fix Xen hvm s3 bug.
This patch is the qemu patch 1. It adjusts qemu wakeup so that
Xen s3 resume logic (which will be implemented at qemu patch 2)
will be notified after qemu system reset.

Spice has two display interface implementations: One integrated into

qemu-emulated graphics card.
The generic one is activated in case spice is used without qxl. The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed. Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

This is minimalistic and just contains the basic widget infrastructure. The GUI
consists of a menu and a GtkNotebook. To start with, the notebook has its tabs
hidden which provides a UI that looks very similar to SDL with the exception of
the menu bar.
The menu bar allows a user to toggle the visibility of the tabs. Cairo is used
for rendering.
I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU
since it was originally written as a remote display for QEMU. So for the most
part, the approach to rendering and keyboard handling should be pretty solid for
GTK.

read_splashfile() passes the address of an int variable as size_t *
parameter to g_file_get_contents(), with a cast to gag the compiler.
No problem on machines where sizeof(size_t) == sizeof(int).
Happens to work on my x86_64 box (64 bit little endian): the least
significant 32 bits of the file size end up in the right place
(caller's variable file_size), and the most significant 32 bits
clobber a place that gets assigned to before its next use (caller's
variable file_type).
I'd expect it to break on a 64 bit big-endian box.
Fix up the variable types and drop the problematic cast.

Code just now does (simplified for clarity)
if (qemu_savevm_state_iterate(s->file) == 1) {
vm_stop_force_state(RUN_STATE_FINISH_MIGRATE);
qemu_savevm_state_complete(s->file);
}
Problem here is that qemu_savevm_state_iterate() returns 1 when it
knows that remaining memory to sent takes less than max downtime.
But this means that we could end spending 2x max_downtime, one
downtime in qemu_savevm_iterate, and the other in
qemu_savevm_state_complete.
Changed code to:
pending_size = qemu_savevm_state_pending(s->file, max_size);
DPRINTF("pending size %lu max %lu\n", pending_size, max_size);
if (pending_size >= max_size) {
ret = qemu_savevm_state_iterate(s->file);
} else {
vm_stop_force_state(RUN_STATE_FINISH_MIGRATE);
qemu_savevm_state_complete(s->file);
}
So what we do is: at current network speed, we calculate the maximum
number of bytes we can sent: max_size.
Then we ask every save_live section how much they have pending. If
they are less than max_size, we move to complete phase, otherwise we
do an iterate one.
This makes things much simpler, because now individual sections don't
have to caluclate the bandwidth (it was implossible to do right from
there).
