[Libvirt-announce] Entering freeze for libvirt-4.8.0
by Daniel Veillard 28 Sep '18

28 Sep '18

As planned I tagged the release in git and pushed the signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work for me in my limited testing, but there is some red in CI https://ci.centos.org/view/libvirt/ apparently around building. That said it worked fine for me so that could be a temporary error. The plan is to put an rc2 around Friday morning, and then if everything is fine push final verion on Oct 1st next Monday. I will keep an eye on the point raised. Please give it a try to ensure a stable and portable release ! 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] Release of libvirt-4.7.0
by Daniel Veillard 03 Sep '18

03 Sep '18

I didn't do this this week-end, that gave time to Andrea to update the release notes :-) it's now tagged in git and signed tarball and rpms are pushed to the usual place: ftp://libvirt.org/libvirt/ I also pushed a release 4.7.0 for the python bindings but they are virtually equivalent to 4.6.0 ones, you can find them at ftp://libvirt.org/libvirt/python/ This seems a reasonably large release, many commits, not that many people were in vacations last month ! The resulting is a balanced release with new features, improvements, and obviously the usual amount of bug fixes ! New features: - storage: add storage pool iscsi-direct Introduce a new storage pool backend that uses libiscsi instead of iscsiadm. It support basic pool operations: checkPool and refreshPool. - Add support for MBA (Memory Bandwidth Allocation technology) Domain vCPU threads can now have allocated some parts of host memory bandwidth by using the memorytune element in cputune. - qemu: Add support for RISC-V guests riscv32 and riscv64 guest architectures are now supported. Improvements: - qemu: Add ccw support for vhost-vsock Support the vhost-vsock-ccw device on S390. - qemu: Make default machine type independent of QEMU We can't control whether or not QEMU will change its default machine type in the future, or whether downstream distributions will decide to compile out some machine types, so our only option to provide a predictable behavior is taking care of the default ourselves; management applications and users are encouraged to explicitly pick a machine type when creating new guests. - apparmor: Various improvements Rules have been added to deal with a number of scenarios that didn't work correctly. Bug fixes: - esx: Truncate CPU model name Some CPU model names are too long to be stored into the corresponding property, and should be explicitly truncated to avoid unexpected behavior in users of the virNodeGetInfo() API such as virsh nodeinfo. - utils: Remove arbitrary limit on socket_id/core_id Both values were assumed to be smaller than 4096, but in fact they are entirely hardware-dependent and there have been reports of machines presenting much bigger values, preventing libvirt from working correctly; all such limits have now been removed. Thanks everybody for your help with this release be it with code, bug reports, patch reviews, documentation, ... Enjoy !

[Libvirt-announce] Entering freeze for libvirt-4.7.0
by Daniel Veillard 30 Aug '18

30 Aug '18

Sorry I forgot to announce it but we are the last week of the month, so it's about time, I tagged RC1 in git and pushed the signed tarball and rpms to the usual place earlier today: ftp://libvirt.org/libvirt/ this seems to work well in my limited testing but as usual we need more review and check on other platforms or OSes before the release. In general https://ci.centos.org/view/libvirt/ is green except for glib bindings and for the master build (weird!) I will likely push the rc2 Thursday morning, but I mwill be travelling at the end of the week so that may depends on conditions, and hopefully the release during this w.e. thanks for giving it a try !

[Libvirt-announce] Release of libvirt-4.6.0
by Daniel Veillard 06 Aug '18

06 Aug '18

Okay it took a bit longer than usual but the relrase is out, it's tagged in git and signed tarball and rpms have been pushed to the usual place, but there was quite a few bug fixes going in after RC2 was cut. ftp://libvirt.org/libvirt/ I also made libvirt-python 4.6.0 bindings release in a similar fashion available at : ftp://libvirt.org/libvirt/python/ So though the release note don't list any bug fixes we know there is a batch of those in, otherwise this is mainly features and improvement targetting QEmu and virsh users: New features: - qemu: Implement the HTM pSeries feature Users can now decide whether HTM (Hardware Transactional Memory) support should be available to the guest. - qemu: Enable VNC console for mediated devices Host devices now support a new atribute 'display' which can be used to turn on frame buffer rendering on a vgpu mediated device instead of on an emulated GPU, like QXL. Improvements: - qemu: Introduce a new video model of type 'none' Introduce a new video model type that disables the automatic addition of a video device to domains with 'graphics' specified in their XML. This can be useful with GPU mediated devices which can serve as the only rendering devices within the guest. - virsh: Add --alias to attach-disk and attach-interface commands Add option --alias to set customized device alias name when using attach-disk or attach-interface commands. - virsh: Support usb and sata address to attach-disk Usb or sata address could be used when attach-disk with --address. For example, use usb address as usb:<bus>.<port>, use sata address as <controller>.<bus>.<unit>. Thanks everybody for your help with this release, hopefully the next one beginning of Sept will be more timely !

[Libvirt-announce] Entering freeze for libvirt-4.6.0
by Daniel Veillard 31 Jul '18

31 Jul '18

As suggested yesterday, I have just tagged the release candidate 1 in git, and pushed signed tarbal and rpms to the usual place: ftp://libvirt.org/libvirt/ seems to work fine with my limited testing, and https://ci.centos.org/view/libvirt/ is all green (except for virt-viewer-master-rpm ?) so things looks pretty good for me but please try it out on different systems and OSes. If everything goes well I will push rc2 on Tuesday targetting Thursday for the final release (or Friday if I get stuck in travels). thanks in advance for trying it out !

[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 !

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.
