Remove the default compiled out tunnel channel, add the always available
cursor channel. Optimally the man page would depend on compiled in
options, but that's harder to do.

Only print options in the help output that are accepted by our arch.
This is less confusing for users and also for other programs that
consume the help output.
The options affected are:
-g and -prom-env only displayed on PPC or SPARC
-win2k-hack, -rtc-td-hack, -no-fd-bootchk, -no-acpi, -no-hpet,
-acpitable, -smbios only displayed on i386
-semihosting only displayed on ARM, M68K or XTENSA

This patch adds the -drive copy-on-read=on|off command-line option:
copy-on-read=on|off
copy-on-read is "on" or "off" and enables whether to copy read backing
file sectors into the image file. Copy-on-read avoids accessing the
same backing file sectors repeatedly and is useful when the backing
file is over a slow network. By default copy-on-read is off.

This patch create a synthetic file system with mount tag
v_synth when -virtfs_synth command line option is specified
in qemu. The synthetic file system can be mounted in guest
using 9p using the below command line
mount -t 9p -oversion=9p2000.L,trans=virtio v_synth <mountpint>
Synthetic file system enabled different qemu subsystem to register
callbacks for read and write events from guest. The subsystem
can create directories and files in the synthetic file system as show
in ex below
qemu_v9fs_synth_mkdir(NULL, 0777, "test2", &node);
qemu_v9fs_synth_add_file(node, 0777, "testfile",

This patch adds -drive cache=directsync for O_DIRECT | O_SYNC host file
I/O with no disk write cache presented to the guest.
This mode is useful when guests may not be sending flushes when
appropriate and therefore leave data at risk in case of power failure.
When cache=directsync is used, write operations are only completed to
the guest when data is safely on disk.
This new mode is like cache=writethrough but it bypasses the host page
cache.

This patch almost rewrites acpi_table_add() function
(but still leaves it using old get_param_value() interface).
The result is that it's now possible to specify whole table
(together with a header) in an external file, instead of just
data portion, with a new file= parameter, but at the same time
it's still possible to specify header fields as before.
Now with the checkpatch.pl formatting fixes, thanks to
Stefan Hajnoczi for suggestions, with changes from
Isaku Yamahata, and with my further refinements.

Added options to let qemu transfer two configuration files to bios:
"bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command
-boot splash=P,splash-time=T
P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit
is ms. With these two options, if user invoke qemu with menu=on option, then
a splash picture would be showed in a given time. For example:
qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000
would make boot.bmp shown as a brand with 5 seconds in the booting up process.
This feature need the new seabios's support, which could be got from git.

All other boolean arguments accept on|off - except for slirp's restrict.
Fix that while still accepting the formerly allowed yes|y|no|n, but
reject everything else. This avoids accidentally allowing external

'restrict=no'.

-machine somehow suggests that it selects the machine, but it doesn't.
Fix that before this command is set in stone.
Actually, -machine should supersede -M and allow to introduce arbitrary
per-machine options to the command line. That will change the internal
realization again, but we will be able to keep the user interface
stable.

Turn on SASL support by appending "sasl" to the spice arguments, which
requires that the client use SASL to authenticate with the spice. The
exact choice of authentication method used is controlled from the
system / user's SASL configuration file for the 'qemu' service. This
is typically found in /etc/sasl2/qemu.conf. If running QEMU as an
unprivileged user, an environment variable SASL_CONF_PATH can be used
to make it search alternate locations for the service config. While
some SASL auth methods can also provide data encryption (eg GSSAPI),
it is recommended that SASL always be combined with the 'tls' and
'x509' settings to enable use of SSL and server certificates. This
ensures a data encryption preventing compromise of authentication
credentials.
It requires support from spice 0.8.1.

This option gives the ability to switch one "accelerator" like kvm, xen
or the default one tcg. We can specify more than one accelerator by
separate them by a colon. QEMU will try each one and use the first whose
works.
So,
./qemu -machine accel=xen:kvm:tcg
which would try Xen support first, then KVM and finally TCG if none of
the other works.
By default, QEMU will use TCG. But we can specify another default in the
global configuration file.

When MSI is off, each interrupt needs to be bounced through the io
thread when it's set/cleared, so vhost-net causes more context switches and
higher CPU utilization than userspace virtio which handles networking in
the same thread.
We'll need to fix this by adding level irq support in kvm irqfd,
for now disable vhost-net in these configurations.
Added a vhostforce flag to force vhost-net back on.
