As planned I tagged the release in git earlier today and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also pushed the python bindings at ftp://libvirt.org/libvirt/python This release seems to be very heavy on new features, but under the hood there is as usuall a number of bug fixes and refactoring patches: New features: - qemu: Add Hyper-V PV IPI and Enlightened VMCS support The QEMU driver now has support for Hyper-V PV IPI and Enlightened VMCS for Windows and Hyper-V guests. - qemu: Added support for PCI devices on S390 PCI addresses can now include the new zpci element which contains uid (user-defined identifier) and fid (PCI function identifier) attributes and makes the corresponding devices usable by S390 guests. - Support changing IOThread polling parameters for a live guest Introduced virDomainSetIOThreadParams which allows dynamically setting the IOThread polling parameters used by QEMU to manage the thread polling interval and the algorithm for growth or shrink of the polling time. The values only affect a running guest with IOThreads. The guest's IOThread polling values can be viewed via the domain statistics. - Xen: Add support for PVH The libxl driver now supports Xen's PVH virtual machine type. PVH machines are enabled with the new "xenpvh" OS type, e.g. <os><type>xenpvh</type></os> - qemu: Added support for CMT (Cache Monitoring Technology) Introduced cache monitoring using the monitor element in cachetune for vCPU threads. Added interfaces to get and display the cache utilization statistics through the command 'virsh domstats' via the virConnectGetAllDomainStats API. - qemu: Add support for nested HV for pSeries guests Nested HV support makes it possible to run nested (L2) guests with minimal performance penalty when compared to regular (L1) guests on ppc64 hardware. Bug fixes: - Xen: Handle soft reset shutdown event The pvops Linux kernel uses soft reset to handle the crash machine operation. The libxl driver now supports the soft reset shutdown event, allowing proper crash handling of pvops-based HVM domains. Thanks everybody for your contribution toward this release, be it with ideas, bug reports, patches reviews, docs, localization... Remember, next release should be around mid-January, 5.0.0, in the meantime enjoy the release and end of years vacations you may have !
