Hello,
On behalf of the QEMU Team, I'd like to announce the availability of
the QEMU 2.0.0 release. This is one of our most extensive releases ever, with
2,500+ commmits from 179 authors.
http://wiki.qemu.org/download/qemu-2.0.0.tar.bz2
The full list of changes are available at:
http://wiki.qemu.org/ChangeLog/2.0
Highlights include:
* Initial support for KVM on AArch64 systems (some features such as migration
are not yet implemented)
* Support for all 64-bit mode ARMV8 user-accessible instructions except for
the optional CRC and crypto extensions
* Support for new 32-bit mode ARMv8 instructions in TCG
* Support for the allwinner-a10-based board "-M cubieboard"
* Support for POWER Altivec 2.07 and VSX instructions when running under TCG
* Support for boot order in pSeries emulation
* The Q35 x86 machine-type now supports CPU hotplug.
* On the PIIX x86 machine-type, PCI hotplug now supports devices behind a
bridge (for bridges not added by hotplug; hot-plugged bridges can still use
the PCI Standard Hot-Plug Controller)
* Support for the Hyper-V reference time counter via the "hv-time" suboption
of "-cpu". This can improve performance of Windows guests substantially for
applications that do many floating-point or SIMD operations. (Requires KVM
and Linux 3.14).
* ACPI tables generated by QEMU can now be used by OVMF
(https://wiki.ubuntu.com/UEFI/OVMF) firmware. OVMF starting with SVN r15420
is needed. In particular hotplug, pvpanic device and other ACPI based
features now work for OVMF
* PCI passthrough of devices with a ROM now work on Xen
* support for suspend-to-RAM in the XHCI USB controller
* GTK UI is now supported on Windows hosts
* New management interfaces for CPU and virtio-rng hotplug
* Improved reliability for live migration when using qcow2 images
* Live snapshot merging
* Experimental support in virtio-blk for M:N threading model: if you specify
x-dataplane=on, you can also create I/O threads with "-object iothread" and
point virtio-blk devices to the desired iothread with the "x-iothread"
property. Properties of the running iothreads can be queried with the QMP
command "query-iothreads".
* Network block drivers (curl, iscsi, rbd, ssh, glusterfs) can be built as
shared library modules with "--enable-modules" configure option.
* QEMU is now able to operate even if the underlying storage requires the
buffer size to be a 4K multiple. This is the case for 4K-native disks (with
cache=none or when accessed through iscsi:// URLs) and some raw devices
* QEMU can access NFSv3 shares directly from userspace using libnfs.
* Improvements to the TCG optimizer make it produce faster code
* Tracing QEMU via LTTng 2.x is now supported
* And lots more...
Thank you to everyone involved!
Sincerely,
Michael Roth
