Log Message:
Update to 1.3.0

    The sendkey monitor command is now available via QMP.

All targets
    QEMU can now use the Linux VFIO driver to assign PCI devices to a virtual 
    The bus master configuration bit for PCI devices is now emulated. PCI 
devices cannot anymore perform DMA without setting the bit before. This may 
break firmware that wasn't tested on real hardware.

    Loongson Multimedia Instructions are now implemented.
    MIPS32/64 ASE DSP Instructions are now implemented.

    The TSC frequency can be larger than 2.147 GHz.
    Configuration files do not support anymore the cpudef section.
    TCG (emulation) supports the SMEP (Supervisor Mode Execution Prevention) 
and SMAP (Supervisor Mode Access Prevention) features of newer x86 processors.
    The "cpudef" config file section is now deprecated and will be removed in 
    New CPU models: "Haswell" (new features: fma, pcid, movbe, fsgsbase, bmi1, 
hle, avx2, smep, bmi2, erms, invpcid, rtm) and "Opteron_G5" (new features: tbm, 
f16c, fma)
    Added Intel Q35 chipset as a new machine type, '--machine q35'. Adds PCIe 
support. Requires an updated SeaBIOS (bios.bin), and '-acpitable 
file=/seabios-path/q35-acpi-dsdt.aml' to run.

    Single precision floating point instructions are now implemented.

Device emulation
    Emulation of the MC146818 real-time clock (used on PC and several other 
boards) does not wake up QEMU anymore every second to update the clock.
    USB3 has been vastly improved, including support for USB mass storage 
devices and MSI/MSI-X support for the XHCI controller.
    USB redirection now supports live migration.
    Several bugs in the AHCI controller were fixed to support recent Windows 
    ivshmem now has a "use64" property which will make the ivshmem driver 
register a 64-bit memory BAR.
    New paravirtualized hardware random number generator device, VirtIORNG.

Network devices
    Some problems were fixed leading to bad receive performance of E1000 and 
Xen network cards.

Block devices
    qemu-img now can output information in JSON format using "qemu-img info 
    Glusterfs volumes can be accessed with "gluster://" URIs for "-drive" and 
similar options. Optionally the transport can also be specified, as in 
"gluster+tcp://" (other supported transports are "unix" and "rdma").
    Options on the QMP streaming command direct the job to pause on 
encountering errors, or to ignore them altogether.
    A new block job is supported: live block commit (also known as "snapshot 
deletion") moves data from an image to another in the backing file chain. With 
the current implementation of QEMU 1.3, the "source" image may not be the 
active one.
    A new block job is supported: live disk mirroring (also known as "storage 
migration") moves data from an image to another. A new command 
"block-job-complete" is used to switch the VM to use the destination image 
    Block jobs can now be paused and resumed from the monitor.
    NBD block devices can now be specified using URI syntax. "nbd://" defaults 
to TCP transport, while "nbd+tcp://" and "nbd+unix://" can be used (similar to 
Gluster) to specify it. URI syntax simplifies access to named exports; the 
export name is simply the "path" component of the URI.
    NBD connections to Unix sockets support relative paths.
    QEMU embeds an NBD server, accessible via the monitor. The NBD server 
allows live access to the image seen by the VM. Note that the embedded server 
uses "named exports", which QEMU can access using the "nbd://host:port/name" 
    Windows hosts support asynchronous disk I/O.

Live Migration, Save/Restore
    The "stop" and "cont" commands have new semantics on the destination 
machine during migration. Previously, the outcome depended on whether the 
commands were issued before or after the source connected to the destination 
QEMU: in particular, "cont" would fail if issued before connection, and "undo" 
the effect of the -S command-line option if issued after. Starting from this 
version, the effect of "stop" and "cont" will always take place at the end of 
migration (overriding the presence or absence of the -S option) and "cont" will 
never fail. This change should be transparent, since the old behavior was 
usually subject to a race condition.
    The monitor now remains responsive during incoming migration. The new NBD 
server is also available during incoming migration.

    QEMU will only send changed screen content to the Spice client when running 
in legacy VGA mode.
    Seamless migration support.
    Composite QXL commands (for linux guests).
    Multiple monitors on a single pci device.
    Arbitrary resolution support.
    Device based monitor configuration notification (for future drivers).
    various bug fixes and assertion removals in favor of a guest_bug mode.
    require spice-server >= 0.12.0

    QEMU now supports "old-style" PCI device assignment, which was the last 
missing feature from the qemu-kvm fork. Despite some remaining minor 
differences between qemu-kvm and QEMU, it is possible to switch from qemu-kvm 
to QEMU as soon as your guests can be rebooted. Live migration from qemu-kvm 
1.2 to QEMU 1.3 is not supported, but can be enabled easily by downstream 
distributions who want to switch their packages from qemu-kvm to QEMU.

    QEMU can now be used to live-migrate Xen domains.

    SLIRP's TFTP server has improved performance, can transmit files bigger 
than 32 MB, and supports the block size option.

Guest agent
    The guest agent will now store the state file in /var/run by default.

Host support
    SPARCv7 and v8 support was removed.

Build dependencies
    QEMU can now be built with Clang.
    QEMU now uses pixman. QEMU configure will detect and use a system pixman if 
the development headers are ailable (they should be available for most recent 
Linux distros). As a fallback, we provide an internal copy of the pixman 
sources which will be used if there is no set of system pixman libraries. 
Compiling these will require autoconf.
    Compiling QEMU ver 0.12 or better.
