New localPtr attribute for "ip" element in network XML qemu: Support QEMU group I/O throttling Add the capability to allow group I/O throttling via a new domain <disk> <iotune> subelement "group_name" to allow sharing I/O throttling quota between multiple drives. nss: Introduce libvirt-guest New libvirt-guest nss module that translates libvirt guest names into IP addresses. daemon: Add support for runtime logging settings adjustment Logging-related settings like log outputs and filters can now be adjusted during runtime using the admin interface without the necessity of the daemon's restart. storage: Add virStorageVolInfoFlags API Add the API to support using the VIR_STORAGE_VOL_GET_PHYSICAL flag in order to return the host physical size in bytes of the image container in the allocation field of the _virStorageVolInfo structure. The --physical flag has been added to the virsh vol-info command to access the data. libxl: Implement virDomainGetMaxVcpus API
perf: Add more perf statistics Add support to get the count of branch instructions executed, branch misses, bus cycles, stalled frontend cpu cycles, stalled backend cpu cycles, and ref cpu cycles by applications running on the platform. conf: Display <physical> for volume xml Add a display of the <physical> size of a disk volume in the output of the volume XML. qemu: Use virtio-pci by default for aarch64 mach-virt guests virtio-pci provides several advantages over virtio-mmio, such as the ability to hotplug devices and improved performance. While opting in to virtio-pci has been possible for a while, newly-defined guests will now use it automatically. vbox: remove support for VirtualBox 3.x and older Those old VirtualBox versions have been unsupported by upstream for a long time and the API of 4.0 and newer has diverged enough to require code abstractions to handle differences. Removing support for those old versions drops lots of code from the driver and simplifies the logic to ease implementation of new features going forward. virsh: pool-info: introduce option --bytes Add option --bytes to virsh pool-info in order ti allow display of units in bytes rather than default of human readable output.
qemu: Correct GetBlockInfo values For an active domain, correct the physical value provided for a raw sparse file backed storage and the allocation value provided for a qcow2 file backed storage that hasn't yet been opened on the domain. qemu: Make virtio console usable on ppc64 guests The chardev detection code has been improved and can now handle this configuration properly. qemu: Enable mount namespace To avoid funny races with udev relabelling devices under our hands and to enhance security, libvirt now spawns each qemu process with its own /dev.
shmem: Add support for additional models The shmem device can now utilize QEMU's ivshmem-plain and ivshmem-doorbell, more modern versions of ivshmem. vbox: Add VirtualBox 5.1 support libssh: New transport The new libssh transport allows one to connect to a running libvirtd via SSH, using the libssh library; for example: qemu+libssh://server/system. vhost-scsi: Add support scsi_host hostdev passthrough Add the capability to pass through a scsi_host HBA and the associated LUNs to the guest. qemu: Users can now enable debug logging for native gluster volumes in qemu using the "gluster_debug_level" option in qemu.conf memory hotplug: Slot numbers for memory devices are now automatically allocated and thus persistent. In addition slot numbers can be specified without providing a base address, which simplifies user configuration qemu: Express devices will be placed on PCIe bus by default For machine types that use a PCI Express root bus (e.g. x86_64/Q35 and aarch64/virt), any unaddressed PCI device that is an Express device (all virtio-1.0 devices, e1000e, nec-xhci, vfio assigned devices) will be placed on an Express controller (i.e. a pcie-root-port) instead of a legacy PCI controller (i.e. pci-bridge) with the root ports added as needed.
docs: Better documentation for migration APIs and flags vbox: Address thread safety issues virsh: Add support for passing an alternative persistent XML to migrate command vhostuser: Allow hotplug of multiqueue devices NEWS: Switch to an improved format List user-visible changes instead of single commits for a better high-level overview of differences between libvirt releases. website: Modernize layout and branding The libvirt website looked very cluttered and outdated; it has now been completely overhauled, resulting in a design that's better organized and more pleasant to look at.
