vnc/spice: add set_passwd monitor command.
vnc: support password expire
vnc: auth reject cleanup
spice: add qmp 'query-spice' and hmp 'info spice' commands.
spice: connection events.
spice: add qxl device
spice: add qxl vgabios binary.

qxl is a paravirtual graphics card. The qxl device is the bridge
between the guest and the spice server (aka libspice-server). The
spice server will send the rendering commands to the spice client, which
will actually render them.
The spice server is also able to render locally, which is done in case
the guest wants read something from video memory. Local rendering is
also used to support display over vnc and sdl.
qxl is activated using "-vga qxl". qxl supports multihead, additional
cards can be added via '-device qxl".
[ v2: add copyright to files ]
[ v2: use qemu-common.h for standard includes ]
[ v2: create separate qxl-vga device for primary ]

Add an option to specify the host IP to send multicast packets from,
when using a multicast socket for networking. The option takes an IP
address and sets the IP_MULTICAST_IF socket option, which causes the
packets to use that IP's interface as an egress.
This is useful if the host machine has several interfaces with several
virtual networks across disparate interfaces.

Make listening address configurable. Also add options to
force using IPv4 or IPv6.

This allows to enforce tls or plaintext usage for certain spice
channels.

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 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.

This is equivalent to SM_PASSTHROUGH security model.
The only exception is, failure of privilige operation like chown
are ignored. This makes a passthrough like security model usable

Libvirt parses qemu help output to determine qemu features. In particular
it probes for the following: "cache=writethrough|writeback|none". The
addition of the unsafe cache mode was inserted within this string, as
opposed to being added to the end, which impacted libvirt's probe.
Unbreak libvirt by keeping the existing cache modes intact and add
unsafe to the end.
This problem only manifests itself if a caching mode is explicitly
specified in the libvirt xml, in which case older syntax for caching is
passed to qemu, which it no longer understands.

The new option is:
-fsdev fstype,id=myid,path=/share_path/,security_model=[mapped|passthrough]
-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.

Currently the commandline to create a virtual-filesystem pass-through between
the guest and the host is as follows:
#qemu -fsdev fstype,id=ID,path=path/to/share \
-device virtio-9p-pci,fsdev=ID,mount_tag=tag \
This patch provides a syntactic short-cut to achieve the same as follows:
#qemu -virtfs fstype,path=path/to/share,mount_tag=tag
This will be internally expanded as:
#qemu -fsdev fstype,id=tag,path=path/to/share, \
-device virtio-9p-pci,fsdev=tag,mount_tag=tag \

Some more command line options had entries for command line help,
but documentation for texi and derived formats (man, html, info)
was missing.
For conditional options, the texi documentation was added
unconditionally.
This seems reasonable because typically man pages are
shared, and html users expect to see one documentation
(not several nearly identical documents for the different
systems).

A new option, -nodefconfig is introduced to prevent loading from the default
config location. Otherwise, two configuration files will be searched for,
qemu.conf and target-<TARGET_NAME>.conf.
To ensure that the default configuration is overridden by a user specified
config, we introduce a two stage option parsing mechanism.

This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.
The virtio console is now a very simple qdev device that sits on the
virtio-serial-bus and communicates between the bus and qemu's chardevs.
This commit also includes a few changes to the virtio backing code for
pci and s390 to spawn the virtio-serial bus.
As a result of the qdev conversion, we get rid of a lot of legacy code.
The old-style way of instantiating a virtio console using
-virtioconsole ...
is maintained, but the new, preferred way is to use
-device virtio-serial -device virtconsole,chardev=...
With this commit, multiple devices as well as multiple ports with a
single device can be supported.
For multiple ports support, each port gets an IO vq pair. Since the
guest needs to know in advance how many vqs a particular device will
need, we have to set this number as a property of the virtio-serial
device and also as a config option.
In addition, we also spawn a pair of control IO vqs. This is an internal
channel meant for guest-host communication for things like port
open/close, sending port properties over to the guest, etc.
This commit is a part of a series of other commits to get the full
implementation of multiport support. Future commits will add other
support as well as ride on the savevm version that we bump up here.

Add generic support for debugging consoles (simple I/O ports which
when written to cause debugging output to be written to a target.)
The current implementation matches Bochs' port 0xe9, allowing the same
debugging code to be used for both Bochs and Qemu.
There is no vm state associated with the debugging port, simply
because it has none -- the entire interface is a single, stateless,
write-only port.
Most of the code was cribbed from the serial port driver.
v2: removed non-ISA variants (they can be introduced when/if someone
wants them, using code from the serial port); added configurable
readback (Bochs returns 0xe9 on a read from this register, mimic that
by default) This retains the apparently somewhat controversial user
friendly option, however.
v3: reimplemented the user friendly option as a synthetic option
("-debugcon foo" basically ends up being a parser-level shorthand for
"-chardev stdio,id=debugcon -device isa-debugcon,chardev=debugcon") --
this dramatically reduced the complexity while keeping the same level
of user friendliness.
v4: spaces, not tabs.
v5: update to match current top of tree. Calling qemu_chr_open()
already during parsing no longer works; defer until we are parsing the
other console-like devices.

This patch adds infrastructure and command line option for setting
global defaults for device properties, i.e. you can for example use
-global virtio-blk-pci.vectors=0
to turn off msi by default for all virtio block devices. The config
file syntax is:
[global]
driver = "virtio-blk-pci"
property = "vectors"
value = "0"
This can also be used to set properties for devices which are not
created via -device but implicitly via machine init, i.e.
-global isa-fdc,driveA=<name>
This patch uses the mechanism which configures properties for the
compatibility machine types (pc-0.10 & friends). The command line
takes precedence over the machine type values.

This commit adds a flag called 'control' to the '-monitor'
command-line option. This flag enables control mode.
The syntax is:
qemu [...] -monitor control,<device>
Where <device> is a chardev (excluding 'vc', for obvious reasons).
For example:
$ qemu [...] -monitor control,tcp:localhost:4444,server
Will run QEMU in control mode, waiting for a client TCP connection
on localhost port 4444.
NOTE: I've tried using QemuOpts for this, but turns out that it
will try to parse the device part, which should be untouched.

Adds -readconfig and -writeconfig command line switches to read/write
QemuOpts from config file.
In theory you should be able to do:
qemu < machine config cmd line switches here > -writeconfig vm.cfg
qemu -readconfig vm.cfg
In practice it will not work. Not all command line switches are
converted to QemuOpts, so you'll have to keep the not-yet converted ones
on the second line. Also there might be bugs lurking which prevent even
the converted ones from working correctly.
