Windows only flushes its cache of a CDROM if it gets a
SENSE_UNIT_ATTENTION CHECK_CONDITION response to a REQUEST_SENSE
command.
Make sure it does so after we change the CD.

KVM's live migration support included support for exec: URLs, allowing system
state to be written or received via an arbitrary popen()ed subprocess. This
provides a convenient way to pipe state through a compression algorithm or an
arbitrary network transport on its way to its destination, and a convenient way
to write state to disk; libvirt's qemu driver currently uses migration to exec:
targets for this latter purpose.
This version of the patch refactors now-common code from migrate-tcp.c into
migrate.c.

Generate an option rom instead of using a hijacked boot sector for kernel
booting. This just requires adding a small option ROM header and a few more
instructions to the boot sector to take over the int19 vector and run our
boot code.
A disk is no longer needed when using -kernel on x86.

This patch adds very basic KVM support. KVM is a kernel module for Linux that
allows userspace programs to make use of hardware virtualization support. It
current supports x86 hardware virtualization using Intel VT-x or AMD-V. It
also supports IA64 VT-i, PPC 440, and S390.
This patch only implements the bare minimum support to get a guest booting. It
has very little impact the rest of QEMU and attempts to integrate nicely with
the rest of QEMU.
Even though this implementation is basic, it is significantly faster than TCG.
Booting and shutting down a Linux guest:
w/TCG: 1:32.36 elapsed 84% CPU
w/KVM: 0:31.14 elapsed 59% CPU
Right now, KVM is disabled by default and must be explicitly enabled with
-enable-kvm. We can enable it by default later when we have had better
testing.

The code in hw/cirrus_vga.c has changed a lot between CVE-2007-1320 has
been announced and the patch has been applied. As a consequence it has
wrongly applied and QEMU is still vulnerable to this bug if using VNC.

This patch makes qemu keep track of the character devices in use and
implements a "info chardev" monitor command to print a list.
qemu_chr_open() sticks the devices into a linked list now. It got a new
argument (label), so there is a name for each device. It also assigns a
filename to each character device. By default it just copyes the
filename passed in. Individual drivers can fill in something else
though. qemu_chr_open_pty() sets the filename to name of the pseudo tty
allocated.
Output looks like this:
(qemu) info chardev
monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait
serial0: filename=unix:/tmp/run.sh-26827/console,server
serial1: filename=pty:/dev/pts/5

The current DMA routines are driven by a call in main_loop_wait() after every
select.
This patch converts the DMA code to be driven by a constantly rescheduled
bottom half. The advantage of using a scheduled bottom half is that we can
stop scheduling the bottom half when there no DMA channels are runnable. This
means we can potentially detect this case and sleep longer in the main loop.
The only two architectures implementing DMA_run() are cris and i386. For cris,
I converted it to a simple repeating bottom half. I've only compile tested
this as cris does not seem to work on a 64-bit host. It should be functionally
identical to the previous implementation so I expect it to work.
For x86, I've made sure to only fire the DMA bottom half if there is a DMA
channel that is runnable. The effect of this is that unless you're using sb16
or a floppy disk, the DMA bottom half never fires.
You probably should test this malc. My own benchmarks actually show slight
improvement by it's possible the change in timing could affect your demos.
Since v1, I've changed the code to use a BH instead of a timer. cris at least
seems to depend on faster than 10ms polling.

this patch allows to fully use a tape device connected to qemu through
the scsi-generic interface.
Previous patch introduced tape SCSI commands management, this one
improve error case management:
- the SCSI controller command completion must be called with the status
value, not the sense value. In the case of scsi-generic, the SCSI status
is given by the field status of sg_io_hdr_t (the value is left shifted
by one regarding status codes defined in /usr/include/scsi/scsi.h)
- when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to
controller can be 0. LSI controller emulation doesn't know how to manage
this. A workaround found is to call the completion routine with
SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0.
This patch also manages correctly the block size of the tape device.
This patch has been tested with a real tape device "HP C5683A", linux
guest (debian etch) and tools like "mt", "tar" and "btape".
Windows guest is not better supported than before...

This patch allows QEMUFile's read and write operations to return
negative error codes. This is necessary to detect things like closed

It also removes unused code for QEMUFileFD write path. Finally, it
makes sure to avoid attempting to flush an output buffer if the file
is only being used for input. This was spotted by Uri Lublin.
