(as of commit e00fcfeab3d452cba3d0a08991a39ab15df66424)
System emulation
Incompatible changes
Future incompatible changes
- Three options are using different names on the command line and in configuration file. In particular:
- The "acpi" configuration file section matches command-line option "acpitable";
- The "boot-opts" configuration file section matches command-line option "boot";
- The "smp-opts" configuration file section matches command-line option "smp".
- Starting with QEMU xyz.jkl, -readconfig will standardize on the name for the command line option.
ARM
- Improvements to Allwinner SoC emulation.
- Initial support in TCG for EL2 and EL3.
- Much more complete support for AArch64.
LM32
Support for semihosting.
Microblaze
- Support for u-boot initrd images.
Power
- Support for VFIO (with guest-side IOMMU) on pSeries.
s390
SPARC
x86
- QEMU now presents version 0x14 for the emulated local APIC, for consistency with KVM and improved compatibility with Mac OS X.
- More faithful SMBus controller emulation.
- More faithful CPL (current privilege level) emulation in TCG mode.
KVM
Xen
Xtensa
Device emulation and assignment
SCSI
- Support for MSI and MSI-X in the megasas emulation.
USB
- Support for file-sharing via MTP emulation
- Host USB3 device can be attached to a EHCI (USB 2.0) controller in the guest
VFIO
- Support for RTL8168 NICs.
GUI
- Many bug fixes for the GTK+ interface.
- Mouse wheel support for the SDL 2.0 interface.
Monitor
- More commands support command-line completion.
Migration
- Many fixes to XBZRLE.
Network
Block devices in system emulation
- Filenames can be JSON objects preceded by "json:", for example json:{'driver':'raw','file.filename':'test.img'}. This new syntax can be used in the file property for -drive, but also in qemu-io, qemu-img or backing file names.
Various
Block devices and tools
- Support for compressed (streamOptimized) VMDK images as conversion targets.
TCG
- Improvement to AArch64, Alpha, ia64, MIPS, S390 and SPARC backends.
Tracing
User-mode emulation
- Support for opening /proc/self/exe.
