Hi,
On behalf of the QEMU Team, I'd like to announce the availability of the
QEMU 1.3 release!
http://wiki.qemu.org/download/qemu-1.3.0.tar.bz2
This release contains over 1700 changesets from 118 unique authors.
See the ChangeLog on the wiki for a full changelog:
http://wiki.qemu.org/ChangeLog/1.3
Major features include:
- After nearly 6 years of work, all remaining differences between the
qemu-kvm.git and qemu.git have been merged into qemu.git
- QEMU can now use the Linux VFIO driver to assign PCI devices to a virtual
machine.
- USB3 has been vastly improved, including support for USB mass storage
devices and MSI/MSI-X support for the XHCI controller.
- New paravirtualized hardware random number generator device.
- 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").
- 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.
- A new block job is supported: live disk mirroring (also known as
"storage migration") moves data from an image to another.
- The sendkey monitor command is now available via QMP.
- MIP Loongson Multimedia Instructions are now implemented.
- MIPS32/64 ASE DSP Instructions are now implemented.
- x86: the TSC frequency can be larger than 2.147 GHz.
- TCG (emulation) supports the SMEP (Supervisor Mode Execution
Prevention) and SMAP (Supervisor Mode Access Prevention) features of
newer x86 processors.
- New CPU models: "Haswell" and "Opteron_G5"
- xtensa: Single precision floating point instructions are now implemented.
- 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.
- USB redirection now supports live migration.
- Several bugs in the AHCI controller were fixed to support recent Windows
versions.
- qemu-img now can output information in JSON format using "qemu-img info
--output=json".
- 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.
- QEMU embeds an NBD server, accessible via the monitor.
- Windows hosts support asynchronous disk I/O.
- The monitor now remains responsive during incoming migration. The
new NBD server is also available during incoming migration.
- spice: QEMU will only send changed screen content to the Spice client
when running in legacy VGA mode.
- Improved support for sandboxing using seccomp mode 2 with libvirt
I'd like to thank everyone who contributed to this release by submitting
patches, testing out -rcs, or reporting bugs during the release process!
Regards,
Anthony Liguori
