[Libvirt-announce] Release of libvirt-4.4.0
by Daniel Veillard 04 Jun '18

04 Jun '18

It's finally out, tagged in git, with signed tarball and rpms at the usual place: ftp://libvirt.org/libvirt/ I also made a 4.4.0 release for the python bindings that one can find at ftp://libvirt.org/libvirt/python/ There is apparently more new features than improvements, and no bug fix in this release, I would just guess that people don't feel like updating news.xml on bug fixes, rather than no bug needing fixes for a full month. It may still be a good idea to update to this release and not just for the fun of testing new features ! New features: bhyve: Support locking guest memory Bhyve's guest memory may be wired using the <memoryBacking><locked/></memoryBacking> element. qemu: Provide VFIO channel I/O passthrough support Support passthrough devices that use channel I/O based mechanism in a QEMU virtual machine. qemu: Add support for migration of VMs with non-shared storage over TLS It's now possible to use the VIR_MIGRATE_TLS flag together with VIR_MIGRATE_NON_SHARED_DISK. The connection is then secured using the TLS environment which is setup for the migration connection. Add support for VM Generation ID The VM Generatation ID exposes a 128-bit, cryptographically random, integer value identifier, referred to as a Globally Unique Identifier (GUID) to the guest in order to notify the guest operating system when the virtual machine is executed with a different configuration. Add a new domain XML processing and a domain capabilities feature. Introduce virDomainDetachDeviceAlias This new API enables users to detach device using only its alias. Introduce new virConnectCompareHypervisorCPU and virConnectBaselineHypervisorCPU APIs Unlike the old virConnectCompareCPU and virConnectBaselineCPU APIs, both new APIs consider capabilities of a specific hypervisor. Introduce SCSI persistent reservations support The QEMU driver gained support for qemu-pr-helper which enables guests to issue SCSI commands for persistent reservation. qemu: Implement multiple screen support for virDomainScreenshot While the virDomainScreenshot API supported multihead video cards, the implementation was missing. But now that QEMU implemented it libvirt has done as well. qemu: add support for vhost-vsock-device A new vsock device was introduced, allowing communication between the guest and the host via the AF_VSOCK family. Improvements: qemu: Add suport for OpenGL rendering with SDL Domains using SDL as a graphics backend will now be able to use OpenGL accelerated rendering. qemu: Add support for 'output' audio codec Support QEMU's 'hda-output' codec advertising only a line-out for ich6 and ich9 sound devices. virsh: Enhance event name completion Implement event name completion for some commands (e.g. event, secret-event, pool-event and nodedev-event) Thanks for everybody who contributed to that feature rich release, be it with code, ideas, reviews etc ... Hopefully it won't crash and burn, Enjoy and Banzai !

[Libvirt-announce] Entering freeze for libvirt-4.4.0
by Daniel Veillard 01 Jun '18

01 Jun '18

Done, I tagged RC1 in git and pushed shigned tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ This seems to work fine with my limited testing, as usual before a release it would be good to get more testing scope, especially with other OSes and platforms. ci.centos.org seems to be raising a few issues with bindings, like perl python and go, so worth a check before the release, RC2 on Thursday and then a release over the w.e. is the plan if all goes well, thanks for giving it a try !

Okay, let's make sure python bindings at least have ready as I will push them along this w.e., thanks for checking :-) Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[Libvirt-announce] Release of libvirt-4.3.0
by Daniel Veillard 02 May '18

02 May '18

As planned the release is done, it is tagged into git and I pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also pushed a release of the python bindings libvirt-python 4.3.0 at ftp://libvirt.org/libvirt/python As usual this release is a balance of features, improvement and bug fixes, however it is to note that this release also remove the Xen daemon based driver, hopefully by now nobody uses such very old Xen version: New features - qemu: Add support for the pcie-to-pci-bridge controller Pure PCIe guests such as x86_64/q35 and aarch64/virt will now add this controller when traditional PCI devices are in use. - Xen: Support setting CPU features for host-passthrough model The CPU model presented to Xen HVM domains is equivalent to libvirt's host-passthrough model, although individual features can be enabled and disabled via the cpuid setting. The libvirt libxl driver now supports enabling and disabling individual features of the host-passthrough CPU model. Removed features - Xen: Drop the legacy xend-based driver The xm/xend toolstack was deprecated in Xen 4.2 and removed from the Xen sources in the 4.5 development cycle. The libvirt driver based on xend is now removed from the libvirt sources. Improvements - qemu: Support hot plug and hot unplug of mediated devices Libvirt now allows mediated devices to be hot plugged and hot unplugged from a guest rather than reporting an error that this isn't supported. In fact, kernel has been supporting this since 4.10. Bug fixes - Improve handling of device mapper targets When starting a domain with a disk backed by a device mapper volume libvirt also needs to allow the storage backing the device mapper in CGroups. In the past kernel did not care, but starting from 4.16 CGroups are consulted on each access to the device mapper target. thanks everybody for your help on building that release, be it with ideas, code, patches, reviews, documentation, localization, etc... Enjoy this month's release, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[Libvirt-announce] Entering freeze for libvirt-4.3.0
by Daniel Veillard 29 Apr '18

29 Apr '18

As planned I just tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems all fine with my limited testing and jenkins is all green: https://ci.centos.org/view/libvirt/ so so far thing looks good but that won't replace individual testing especially on other arches and OSes ! If thing go well I will push the RC2 over the week-end and target the final 4.3.0 release on Tues or Wed, in the meantime, plase give it some testing !

[Libvirt-announce] Release of libvirt-4.2.0
by Daniel Veillard 01 Apr '18

01 Apr '18

Not April fool one, I made the release on time :-) It's signed in git and signed tarball and rpms are pushed to the usual place: ftp://libvirt.org/libvirt/ I also pushed a python binding 4.2.0 release which can be found at: ftp://libvirt.org/libvirt/python/ New features - Support building with Python 3 Python is required to build libvirt, and up until now only Python 2 could be used as an interpreter. All scripts used during build have now been made compatible with Python 3, which means both major releases of the language are fully supported. - qemu: Provide ccw address support for graphics and input devices Support the virtio-gpu-ccw device as a video device and virtio-{keyboard, mouse, tablet}-ccw devices as input devices on S390. Improvements - qemu: Add logging of guest crash information on S390 On S390, when the guest crashes and QEMU exposes the guest crash information, log the relevant data to the domain log file. - qemu: use arp table of host to get the IP address of guests Find IP address of a VM by arp table on hosts. If someone customizing IP address inside VM, it will be helpful. - Xen: Remove hard-coded scheduler weight The libxl driver was accidentally hard-coding the per-domain scheduler weight to 1000, silently ignoring any user-provided <shares> in <cputune>. The driver now honors <shares>, and defers setting a default value to Xen. Note that the Xen default is 256, so any domains started after this improvement will have one fourth the shares of previously started domains. If all domains must have equal CPU shares, administrators must manually set the weight of previously started domains to 256, or restart them. there is no documented bug fix but there is quite a few there too :-) Thanks everybody for your help getting this release, with patches, reviews, bug reports, documentation, etc. Enjoy !

[Libvirt-announce] ANNOUNCE: libvirt-dbus 0.0.1 released
by Pavel Hrdina 23 Mar '18

23 Mar '18

I'm happy to announce the release of libvirt-dbus 0.0.1. libvirt-dbus wraps libvirt API to provide high-level object-oriented API better suited for dbus-based applications. This is a first release which should be considered as unstable release since we don't promise API stability. You can download it here: https://libvirt.org/sources/dbus/libvirt-dbus-0.0.1.tar.gz This release contains a limited support of libvirt APIs as proof of concept, but we are planning to cover all relevant APIs. Thanks everybody who contributed! Pavel
