[Libvirt-announce] Entering freeze for libvirt-5.0.0
by Daniel Veillard 13 Jan '19

13 Jan '19

As planned I tagged the RC1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I didn't see the 5 patches from Laine in git at that point but those seems to be bug + portability fixes anyway so it should still be possible to have them in say before rc2. Seems to be working fine in my limited testing, and CI seems to be mostly green excepot a few edge cases https://ci.centos.org/view/libvirt/ so that's looking good to me, but as usual it's good to exercice the RCs in various condition to make sure we didn't introdue regressions on some platforms. I plan on RC2 release during the week-end and then if everything goes well push 5.0.0 out on Tuesday for Jan 15 deadline, thanks in advance for giving it some testing !

[Libvirt-announce] Release of libvirt-4.10.0
by Daniel Veillard 03 Dec '18

03 Dec '18

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 !

29 Nov '18

As planned I just tagged the RC1 in git and pushed the signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work fine in my limited testing, https://ci.centos.org/view/libvirt/ seems mostly green so far things looks good, but as usual we need more testing especially on other OSes and architectures. If everything goes fine, I will push the RC2 on Thursday for a final release over the week-end or next Monday. In the meantime please give it some testing !

[Libvirt-announce] Release of libvirt-4.9.0
by Daniel Veillard 04 Nov '18

04 Nov '18

Except an update to the news file no change was pushed to the tree since RC! so that looks like stable enough for release and so I did. It's tagged in git and signed tarball and rpms are available from the usual place: ftp://libvirt.org/libvirt/ I also tagged and pushed python bindings 4.9.0 release which can be found at ftp://libvirt.org/libvirt/python/ This release is a mix, with one important new feature, the new cgroup v2 and one important security bug for libvirt sockets, users are invited to upgrade: New features: - util: Add cgroup v2 support cgroup v2 support has been implemented in libvirt, with both "unified" (v2 only) and "hybrid" (v2 + v1) setups being usable; existing "legacy" (v1 only) setups will keep working. - qemu: Add vfio AP support The QEMU driver now has support to passthrough adjunct processors into QEMU guests on S390. Improvements: - rpc: Make 'genprotocol' output reproducible This is another step towards making libvirt builds fully reproducible. Bug fixes: - security: Fix permissions for UNIX sockets Since 4.5.0, libvirt is using FD passing to hand sockets over to QEMU, which in theory removes the need for them to be accessible by the user under which the QEMU process is running; however, other processes such as vdsm need to access the sockets as well, which means adjusting permissions is still necessary. - cpu_map: Add Icelake model definitions These CPU models will be available in the upcoming 3.1.0 QEMU release. - util: Properly parse URIs with missing trailing slash Some storage URIs were not parsed correctly, in which case libvirt ended up emitting XML that it would then refuse to parse back. Thanks everybody for your contributions to this release whatever form that took (ideas, bug reports, patches, reviews, docs ...), enjoy !

[Libvirt-announce] Entering freeze for libvirt 4.9.0
by Daniel Veillard 01 Nov '18

01 Nov '18

with a bit of delay today, I finally just tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Looks fine in my minimal testing, and most of CI seems to be green except for 3 tests https://ci.centos.org/view/libvirt/ . I will likely push RC2 mid-day on thursday and if everything goes well the final release on the week-end. Please give the RC1 some testing especially on other architectures or oses, thanks in advance, 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-4.8.0
by Daniel Veillard 01 Oct '18

01 Oct '18

It is out, as planned, tagged in git, the signed tarball and rpms are at the usual place: ftp://libvirt.org/libvirt/ I also make a python binding release which include event testing updates, you can find those at ftp://libvirt.org/libvirt/python/ This is a relatively large release considering the number of patches going in please note the Removed Feature section below: New features: - Xen: Support PM Suspend and Wakeup The libxl driver now supports the virDomainPMSuspendForDuration and virDomainPMWakeup APIs. Removed features: - Xen: Drop support for Xen 4.4 and 4.5 Xen 4.4 and 4.5 are no longer supported by the Xen community. Drop support for these older versions and require Xen >= 4.6. - nwfilter: Disallow binding creation in session mode Ensure that a filter binding creation is not attempted in session mode and generates a proper error message. Improvements: - qemu: Retrieve guest hostname through QEMU Guest Agent command QEMU is now able to retrieve the guest hostname using a new QEMU-GA command called 'guest-get-host-name'. Virsh users can execute 'domhostname' for QEMU driver for domains configured to use the Guest Agent. - virsh: Implement vsh-table in virsh and virsh-admin The new API fixes problems with table-alignment, making the tables more readable and deals with unicode. Bug fixes: - storage: Allow inputvol to be encrypted When creating a storage volume based on another volume, the base input volume is allowed to be encrypted. - virsh: Require explicit --domain for domxml-to-native The --domain option for domxml-to-native virsh command has always been documented as required, but commit v4.3.0-127-gd86531daf2 accidentally made it optional. - lxc_monitor: Avoid AB / BA lock race A deadlock situation could occur when autostarting a LXC domain 'guest' due to two threads attempting to take opposing locks while holding opposing locks (AB BA problem). Thanks everybody for your help with this release. Enjoy !

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 !
