[fedora-virt] Fwd: [Qemu-devel] [ANNOUNCE] QEMU 2.0.0 is now available

[Cole Robinson]

qemu 2.0.0 has been released! It's built for rawhide now, should show up in
fedora-virt-preview tomorrow.

I haven't enabled a qemu-system-aarch64 sub package yet: as the announcement
says, it only works on aarch64 hosts which fedora is still in the process of
supporting. My guess is that next qemu release will have something useable for
aarch64 CPU emulation which will allow use of qemu-system-aarch64 on x86,
which is what most people are looking for at the moment.

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.

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
