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!
