[Libvirt-announce] Release of libvirt-4.5.0
by Daniel Veillard 02 Jul '18

02 Jul '18

As planned the release is out, it is tagged in git and I have pushed the signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also made a release of the python bindings 4.5.0 also tagged in git with signed tarball and rpms at: ftp://libvirt.org/libvirt/python This release has a distinct flavour around security, with one added feature and improvement in that direction but also removal of some features which might prove insecure. Beside that a potential crasher was fixed so user are invited to update to this new version: New features: - qemu: Provide TPM emulator support Support QEMU's TPM emulator based on swtpm. Each QEMU guest gets its own virtual TPM. - bhyve: Support specifying guest CPU topology Bhyve's guest CPU topology could be specified using the <cpu><topology ../></cpu> element. - qemu: Add support for extended TSEG size Support specifying extended TSEG size for SMM in QEMU. - qemu: Add support for SEV guests SEV (Secure Encrypted Virtualization) is a feature available on AMD CPUs that encrypts the guest memory and makes it inaccessible even to the host OS. Removed features: - Remove support for qcow/default encrypted volumes Disallow using a qcow encrypted volume for the guest and disallow creation of the qcow or default encrypted volume from the storage driver. Support for qcow encrypted volumes has been phasing out since QEMU 2.3 and by QEMU 2.9 creation of a qcow encrypted volume via qemu-img required usage of secret objects, but that support was never added to libvirt. - Make GnuTLS mandatory Building without GnuTLS is no longer possible. - qemu: Remove allow_disk_format_probing configuration option The option represented a security risk when used with malicious disk images, so users were recommended against enabling it; with this release, it's been removed altogether. Improvements: - capabilities: Provide info about host IOMMU support Capabilities XML now provide information about host IOMMU support. - virsh: Add --all to domblkinfo command Alter the domblkinfo command to add the option --all in order to display the size details of each domain block device from one command in a output table. - qemu: Allow concurrent access to monitor and guest agent Historically libvirt prevented concurrent accesses to the qemu monitor and the guest agent. Therefore two independent calls (one querying the monitor and the other querying guest agent) would serialize which hurts performance. The code was reworked to allow two independent calls run at the same time. - qemu: Allow configuring the page size for HPT pSeries guests For HPT pSeries guests, the size of the host pages used to back guest memory and the usable guest page sizes are connected; the new setting can be used to request that a certain page size is available in the guest. - Add support to use an raw input volume for encryption It is now possible to provide a raw input volume as input for to generate a luks encrypted volume via either virsh vol-create-from or virStorageVolCreateXMLFrom. - qemu: Add support for vsock hot (un)plug and cold (un)plug - qemu: Add support for NBD over TLS NBD volumes can now be accessed securely. - qemu: Implement FD passing for Unix sockets Instead of having QEMU open the socket and then connecting to it, which is inherently racy, starting with QEMU 2.12 we can open the socket ourselves and pass it to QEMU, avoiding race conditions. - virsh: Introduce --nowait option for domstat command When this option is specified, virsh will try to fetch the guest stats but abort instead of stalling if they can't be retrieved right away. Bug fixes: - qemu: Fix a potential libvirtd crash on VM reconnect Initialization of the driver worker pool needs to come before libvirtd trying to reconnect to all machines, since one of the QEMU processes migh have already emitted events which need to be handled prior to us getting to the worker pool initialization. - qemu: Fix domain resume after failed migration Recent versions of QEMU activate block devices before the guest CPU has been started, which makes it impossible to roll back a failed migration. Use the late-block-activate migration capability if supported to avoid the issue. - vmx: Permit guests to have an odd number of vCPUs An odd number of vCPUs greater than 1 was forbidden in the past, but current versions of ESXi have lifted that restriction. Thanks everybody for your contributions to this release, be it with code, ideas, bug reports, patch reviews, documentation, etc... Enjoy the release !

[Libvirt-announce] Entering freeze for libvirt-4.5.0
by Daniel Veillard 29 Jun '18

29 Jun '18

As planned I just tagged it in the git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work fine in my very limited testing, but there seems to be a few things weird on the ci: https://ci.centos.org/view/libvirt/ though it look hard to pinpoint a single culprit, different oses ... Please give it some testing this week it, if everything is fine I will push an RC2 on Friday with hopefully an final release next Monday, please give it a try, thanks, 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] ANNOUNCE: Libvirt TCK release v1.0.0
by Daniel P. Berrangé 11 Jun '18

11 Jun '18

It has been 9 years since the first release of Libvirt TCK, so I'm happy to annonunce a second ever release, with countless accumulated bug fixes and features, is now available from https://libvirt.org/sources/tck/Sys-Virt-TCK-v1.0.0.tar.gz The GPG signature: https://libvirt.org/sources/tck/Sys-Virt-TCK-v1.0.0.tar.gz.asc Is created with my key with a fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) All historical releases are available from: https://libvirt.org/sources/tck/ Changes in this release are: - So many that it is not useful to list them all, please see the GIT history. It is expected to have a 100% pass rate when used with the QEMU driver from current libvirt GIT master, and with 4.4.0 release it should pass everything except some nwfilter tests. The state of the tests wrt other hypervisor drivers is currently an unknown. The intention is that it would work with other drivers, but it has not been tested anytime in recent history. Thanks to everyone who contributed to this new release.

[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 !

[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...
