With that patch applied you'll actually see the guests screen in the
spice client. This does *not* bring qxl and full spice support though.
This is basically the qxl vga mode made more generic, so it plays
together with any qemu-emulated gfx card. You can display stdvga or
cirrus via spice client. You can have both vnc and spice enabled and
clients connected at the same time.
Add -spice command line switch. Has support setting passwd and port for
now. With this patch applied the spice client can successfully connect
to qemu. You can't do anything useful yet though.
This patch drops DT_VNC. The display types are only used to select
select the local display (i.e. curses, sdl, coca, ...). Remote
displays (for now only vnc, spice will follow) can be enabled
independently.
This patch adds an optional command line switch '-trace' to specify the
filename to write traces to, when qemu starts.
Eg, If compiled with the 'simple' trace backend,
[temp@system]$ qemu -trace FILENAME IMAGE
Allows the binary traces to be written to FILENAME instead of the option
set at config-time.

When a 'cont' is issued on a VM that's just waiting for an incoming
migration, the VM reboots and boots into the guest, possibly corrupting
its storage since it could be shared with another VM running elsewhere.
Ensure that a VM started with '-incoming' is only run when an incoming
migration successfully completes.
A new qerror, QERR_MIGRATION_EXPECTED, is added to signal that 'cont'
failed due to no incoming migration has been attempted yet.

The new option is:

-virtfs fstype,path=/share_path/,security_model=[mapped|passthrough],mnt_tag=tag
In the case of mapped security model, files are created with QEMU user
credentials and the client-user's credentials are saved in extended attributes.
Whereas in the case of passthrough security model, files on the
filesystem are directly created with client-user's credentials.

Usually the guest can tell the host to flush data to disk. In some cases we
don't want to flush though, but try to keep everything in cache.
So let's add a new cache value to -drive that allows us to set the cache
policy to most aggressive, disabling flushes. We call this mode "unsafe",
as guest data is not guaranteed to survive host crashes anymore.
This patch also adds a noop function for aio, so we can do nothing in AIO
fashion.
