Changelog 1.5:
http://wiki.qemu.org/ChangeLog/1.5
General
-------
- The default for log output enabled via the '-d' command line switch is now
standard error rather than a file. You can obtain the previous behaviour
using the '-D' command line switch to specify a file to send the logging to.
- QEMU now uses poll rather than select, and thus does not have any
restriction on the number of open file descriptors.
System emulation
----------------
Device emulation
Audio
- The --audio-card-list configure option is not used anymore. Instead, you
can modify default-configs/pci.mak (for the PCI soundcards AC97, HDA and
ES1370) and default-configs/sound.mak (for the ISA soundcards) before
running "make".
- The "shortcut" -soundhw option is now available for all targets that have
a PCI bus.
Device assignment
- VFIO supports primary VGA passthrough using the experimental "x-vga=on"
option. The following devices seem to work: Nvidia 8400gs, 73001e, NVS290;
ATI/AMD Radeon HD5450 and HD7850.
- VFIO devices support the bootindex= property to override the default boot
order for assigned PCI devices.
USB
- Experimental support for USB 3.0 streams, both in the nec-usb-xhci
controller and in the usb-uas USB-attached SCSI device emulation.
- USB device passthrough has been rewritten to use libusb. For Linux, the
two backends can be compiled in a single QEMU executable (if libusb is
enabled, usb-host-linux will be the legacy implementation, usb-host will
be the libusb-based one; if libusb is disabled, usb-host will be the
legacy implementation). For BSD, it has to be chosen at configure time
using --enable/disable-libusb (the default is to use libusb if it is
available, otherwise use the legacy implementation).
SCSI
- QEMU can now emulate the VMware PVSCSI device using "-device pvscsi".
- QEMU can now use tcm_vhost, a virtio-scsi device model based on the
Linux-iSCSI implementation of SCSI.
Network cards
- QEMU can now emulate the VMware paravirtualized network card using
"-device vmxnet3".
ARM
- This release has initial support of KVM for the ARM architecture.
This requires a 3.9 or better Linux kernel and a Cortex-A15 CPU.
- The Zynq board provides a SD host controller interface.
- The PCI controller model for VersatilePB and Realview boards has been
significantly improved in functionality (including MMIO BAR support and
a correct PCI IRQ mapping). Note that Linux kernels currently do not take
advantage of this; however we autodetect kernels that expect the behaviour
of an old broken QEMU and fall back to that. (The old IRQ behaviour can
be forced with "-global versatile_pci.broken-irq-mapping=1" if absolutely
necessary.)
- Incorrect handling of the SRS instruction in Thumb mode has been fixed.
- Performance of TCG emulation of ARM targets is improved over previous
releases.
- Migration and vm save/load now works correctly on the vexpress-a15 and
vexpress-a9 models.
PPC
- Various improvements to TCG code generation
- KVM synchronizes more state
- Fix a few issues that blocked Mac OS X from working (still not 100% there
though!)
- Refactoring and improvement of soft mmu emulation for book3s
- Implement various new instructions for ISA 2.05 and ISA 2.06 compatibility
(-cpu POWER7)
- Implement support for KVM based e500 family watchdog
s390x
- Various accuracy fixes for device emulation
- Faster I/O hypercalls
- Add firmware to boot from virtio-ccw disks
- Guest kernel panics are notified to the host
SPARC
- Improve sun4u interrupt mapping, so that multiple PCI devices can be used
simultaneously
x86
- x86 supports emulation of a TPM (Trusted Platform Module) on machines
that have a hardware TPM
- Various speedups in TCG emulation of x86
- The iPXE ROMs that are distributed with QEMU support EFI
- TCG supports the SSE4.1, SSE4.2, PCLMULQDQ, AES-NI, BMI and ADX extensions.
- A paravirtual device is included that lets the guest notifies kernel
panics to the host.
- CPU hot-add support with cpu-add QMP command. More details
Features/CPUHotplug.
- new CPU properties "feature-words" and "filtered-features" to allow
introspection of supported and not supported CPU features.
- For reference and examples of how the new properties can be used by
libvirt and other components, see:
http://wiki.qemu.org/Features/CPUModels#Interfaces.2Frequirements_for_libvirt
QMP
- QEMU now generates a DEVICE_DELETED event when the guest acknowledges
a device hot-unplug operation.
- Much better handling for non-ASCII codepoints in JSON strings
Character devices
- Character devices gained support for flow control. More details in
Features/ChardevFlowControl
- All kinds of character devices can now be hot-plugged. Character device
hotplug is also supported from the "human" monitor.
Block devices
- IDE and SCSI disks always have the ability to issue "discard" (aka TRIM or
UNMAP) commands. However, by default "discard" commands are silently
ignored as they can cause performance degradation and fragmentation.
To enable them, the "-drive" option now supports a "discard" suboption;
the default value is "ignore" (or its synonym "off"), and the other valid
value is "unmap" (or "on").
- Sheepdog drives can also be specified with URIs.
- iSCSI disks support on-line resizing using block_resize. Similar to block
devices, the resize has to be done first outside QEMU.
- Various performance improvements in qcow2 internal snapshots (savevm).
- The NBD backend has improved latency.
- qemu-nbd can now skip image format probing using the -f/--format
command-line option.
- VHDX (MS Hyper-V) image format has initial read-only support. Dynamic and
fixed sized disks are supported, but not differencing images (e.g. VHDX
images with a backing file). Read-only is strictly enforced, and the
'readonly=on' option must be used for any VHDX images.
- Secure Shell (ssh) support. Access remote disks over ssh using
qemu -drive file=ssh://host/path/to/file
Live Migration
- Further improvements in throughput (up to +130%: 4.2 Gbps in 1.5 vs
1.8 Gbps in 1.4) and latency.
User interface
- QEMU now provides a GTK+ interface. The interface uses the VTE library
to provide better terminal emulation for serial consoles and the monitor.
- A new VNC extension has been added to communicate LED state changes for
the keyboard.
VNC
- Websocket connections can now be encrypted with TLS.
User-mode emulation
-------------------
- Threaded programs are now more stable, though still experimental.
Guest agent
-----------
- New commands in qemu-ga let the host put CPUs online/offline with help
from the guest OS (Linux only)
- Low impact CVE-2013-2007 ("qemu: guest agent creates files with insecure
permissions in daemon mode") is fixed.
- Note for guest administrators: unix domain sockets, logfiles etc.
created by previous versions of qemu-ga do not have their file mode
bits reset by this change; only newly created files have mode 0600
when daemonizing. Please delete your old files or change their
permissions manually when upgrading.
- The guest-file-open QMP command continues to create files with mode
0666 for compatibility reasons.
Host support
------------
- QEMU is now a lot faster on Windows hosts than in previous versions
- libcacard has been ported to Windows.
Known issues
- The GTK+ backend does not compile on BSD systems (including Mac OS X).
This will likely be fixed in a later stable update.

with the alsa, opengl, png, pulseaudio, xrandr, xvideo, and zlib
PKG_OPTIONS. png, xrandr, xvideo, and zlib are enabled by default, since
those are the package's defaults. This relocates libXv from Makefile and
moves the disabling of OpenGL (which i can't see a reason why it is/was
disabled) to options.mk. Add msgmerge, xgettext, and perl to USE_TOOLS.
Set LICENSE to gnu-lgpl-v2.1, which is reflected on HOMEPAGE, but code also
includes gnu-gpl-v2 code, so add that too just to be safe. Bump PKGREVISION
pkgsrc changes:

- Resetting the machine with a write to port 0xCF9 now works.
- The xlevel argument for -cpu option currently silently fix-ups the
user-provided value if it's less than 0x80000000. This will be
removed in future QEMU versions; users are expected to provide valid
xlevel value or QEMU will fail to start.
KVM
- New devices isa-debug-exit and pc-testdev can be used to run
kvm-unit-tests.
Xen
- Persistent grants support implemented in xen_disk, giving substantial
performance improvements.
- xen_disk supports BLKIF_OP_FLUSH_DISKCACHE, making the device safer
against power losses.
- xen_console supports multiple secondary PV consoles.
QMP
- New commands chardev-add and chardev-del add support for hotplugging
character devices.
- New ringbuf-read/ringbuf-write to read and write to memory chardevs
- Various improvements in error messages
Block devices
- Discard operations are now supported on block devices and on
filesystems other than XFS. They are also fully asynchronous now.
- Block device mirroring (also known as storage migration) performance
was greatly improved.
- New experimental threaded backend for virtio-block-pci. This new
backend achieves several times the IOPS of the existing virtio-blk
implementation; for now it can only be used for raw image files and
disables features such as live snapshots and storage migration.
Live Migration
- Moved migration from a timer to a thread, improving latency in
other parts of QEMU and throughput of migration itself
- Many machine models are now correctly marked as not migratable.
Spice
- A new spiceport character device can be used to support arbitrary
communication between the SPICE server on the host and the client.
VNC
- Added support for the Websocket protocol.
User-mode emulation
-------------------
- Fix ppc guest signal handling
- Fix MIPS target
Guest agent
-----------
- qemu-ga supports hooks that are executed when the guest receives
the guest-fsfreeze-freeze and guest-fsfreeze-thaw commands
Host support
------------
- Native asynchronous I/O for Win32 (introduced in 1.3) now actually works.

Changelog:
Changes in 2.6.2 (May 26, 2013):
- CPU
- VMX: implemented VMENTER to non-active guest state (HLT, SHUTDOWN, WAIT-FOR-SIPI)
- VMX: fixed write of guest segment access rights VMCS fields (32-bit field
was truncated to 16-bit)
- CPUID: Don't report Architectural Performance Monitoring in CPUID.
Reporting true capabilities without actually supporting them breaks Win7 x64 installation.
- CPUID: Fixed bx_generic CPUID std leafs (all std leafs > 2 were corrupted)
- CPUID: Enable all supported VMX capabilities for bx_generic CPUID configuration.
- CPUID: Enable X2APIC support for Ivy Bridge CPUDB configuration.
- Configure and compile
- Enabled VMX compilation by default in shortcut scripts.
- Allow CPU_LEVEL=5 configurations (pentium_mmx and amd_k2_chomper) even when Bochs was
compiled with CPU_LEVEL > 5.
- Misc
- Fixes for Bochs port on MorphOS (based on a patch by Thore Sittly):
missing functions, byte-swapping and cdrom support.

to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
* Imported hqx filters.
* Added debugger support.
* Rendered screen is now scaled by a factor of 2 by default.
* Fixed joystick issues. bool_joystick is also enabled by default.
* DGen is now fully controllable from a joystick/joypad.

to read/write in order to save additional data at the end of the current
tape image, rewind/fast forward the tape, and mark it as read-only. See
DOC/USAGE for details.
* Displaying tape position when "Show sector/block counter" is enabled.
* Reworked Cartridge Management menu - now displays filename of the
attached cartridge.
