[Libvirt-announce] Release of libvirt-3.5.0
by Daniel Veillard 04 Jul '17

04 Jul '17

As planned, it is out, I tagged it in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also made a release 3.5.0 of the python bindings with minimal changes compared to 3.4.0, it can be found at: ftp://libvirt.org/libvirt/python/ This is a balanced release with signiciant amounts of both new features, improvements and bug fixes: New features: - qemu: Add support for loadparm for a boot device Add an optional boot parameter 'loadparm' for a boot device. Loadparm is an 8 byte parameter that, when present, is queried by S390 guests via sclp or diag 308. Linux guests on S390 use it to select a boot entry. - Support controlling how video devices are exposed to the bhyve guests The vgaconf attribute was added to video's driver element. Possible values are: on, off, and io. It controlls the way how bhyve exposes video devices to its guests; various guest OSes might require different settings to boot properly. - qemu: Add support for live updates of coalesce settings Users can now use virsh update-device to change the coalesce settings of an interfaces while the domain is running. - qemu: Allow VirtIO devices to use vIOMMU It is now possible to turn on IOTBL for the vIOMMU and have VirtIO devices use it, provided they have been configured appropriately. Improvements: - qemu: block copy job can be used with persistent domains Until now it was not possible to use block copy with persistent VMs. In use cases where it's not required to recover the job after VM shutdown, it's possible to specify VIR_DOMAIN_BLOCK_COPY_TRANSIENT_JOB flag to start the copy job. - JSON pseudo-protocol backing store parser supports new format of qemu 2.9 QEMU 2.9 modified a few structures corresponding to the JSON format of specifying a backing store for a disk image. Libvirt now implements the new format. - Capabilities now include info about host's CAT settings Various information about resource control from the host is gathered and presented in capabilities if available. - apparmor: Several improvements Allow access to Ceph config, EFI firmware on both x86_64 and aarch64, device tree on ppc64 and more. - qemu: Support host-model on POWER9 machines Bug fixes: - qemu: snapshot: retrieve image metadata from user provided files Disk images of an external snapshot created with VIR_DOMAIN_SNAPSHOT_CREATE_REUSE_EXT flag specified would not be scanned for metadata after recent changes. The metadata is necessary to allow keeping relative paths between images when doing a block-commit. - Parse decimal numbers in a locale-independent way Some locales, such as de_DE and pt_BR, use comma rather than dot to separate the integer part from the fractional part of a decimal number; however, several data sources such as the kernel use a locale-independent representation and need to be treated accordingly. - Support compilation with newer compiler and libc versions Several fixes have been included to make compilation with Clang 4.0.0, GCC 7.1 and glibc >= 2.25.90 possible. - qemu: Query name for vhost-user interfaces at runtime This makes it possible to use virsh subcommands such as domiflist and domifstat on vhost-user interfaces. - qemu: Set MTU for hotplugged interfaces correctly When hotplugging a network interface, the MTU was only set on the guest side. Set it on the host side as well. - qemu: Forbid updating MTU for interfaces of running guests The MTU setting can't be modified while the guest is running, so any attempt to alter it at runtime will now result in an error rather than being silently ignored. - qemu: Fix specifying QXL heads with older QEMU releases Specifying the number of QXL heads was not working correctly for QEMU releases older than 1.6. - qemu: Fix migration to older libvirt/QEMU versions When the guest is started, libvirt updates the CPU definition to reflect the actual CPU features to enforce ABI. We need to send original and updated CPU definition in order to support migration to older libvirt/QEMU versions. Only the updated CPU definition was sent to destination. So thanks everybody for your help toward this release, be it code, bug reports, reviews ideas or doc, it's all appreciated ! So please enjoy this new release !

[Libvirt-announce] Entering freeze for libvirt-3.5.0
by Daniel Veillard 02 Jul '17

02 Jul '17

Slightly late so little advance warning see my mail earlier today, I have now tagged RC1 in git head and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work well in my limited testing, https://ci.centos.org/view/libvirt/ is all green except one failed build, so things look smooth overall. Please give it a try to find out issues especially for portability accross systems. If everything goes well I will push an RC2 on Friday, and then make the release on Tuesday, thanks for trying it out, 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-3.4.0
by Daniel Veillard 02 Jun '17

02 Jun '17

It's out ! The release is tagged in git, the tree is open ! I pushed the signed tartball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also rolled out the libvirt-python-3.4.0 release that you can find at ftp://libvirt.org/libvirt/python/ This is a feature and improvements driven release, as you can see below there is a number of point with direct user visible improvements: * New features - Improved streams to efficiently transfer sparseness New extension to virStream was implemented so that virStorageVolDownload and virStorageVolUpload can preserve file sparseness. - I/O APIC type can be specified for QEMU/KVM domains The ioapic tag was added to domain features, so the type of the I/O APIC can now be specified (e.g. putting it in userspace for KVM domains). - The reason for VM shutdown is reported, if known QEMU 2.10 will be able to report the reason for shutting down (whether that was caused by the guest or not), and libvirt is prepared for that and reports that information in its shutdown event as well, if it is known. * Improvements - Repository now has new README.md file The new file uses markdown syntax, so it looks better on github and possibly other web pages, but it has also more useful information. The old README is now symlink to the new file. - qemu: Use GICv2 by default for aarch64/virt TCG guests The emulated GICv3 has some limitations that make it unusable as a default; use GICv2 until they're sorted out. This change makes it once again possible to run aarch64/virt guests on a x86_64 host without having to tweak their configuration. - Additional capabilities for the node_device module Introduce two new capabilities to the node_device module. The first is for CCW devices, most common on the S390 architecture. The second is for fibre channel-backed SCSI devices and exposes the fc_remote_port sub-capability to SCSI target devices. - Node devices now report Mediated device capabilities Endpoint devices support new mdev capability and their parents now report the supported types in new mdev_types capability. - Capabilities now report information about host caches If supported in the kernel, host capabilities will now list L3 caches. The code for other levels was added as well, but only L3 caches are reported currently. - POWER9 CPU model was added It is now properly reported in host capabilities. - libxl: NUMA sibling distances are now reported in host capabilities - VMDK version 3 files are now properly detected - Interrupt remapping and Extended interrupt mode for IOMMU devices These two new features can now be controlled with new <driver intremap='on/off' eim='on/off'/> tag for iommu devices. - Graphics in libxl domains now have default addresses Even though there were default addresses before this change, they were not saved in the XML. It is now possible to see and control the listen addresses properly. - Default USB controllers are now added for devices in libxl domains Even though they were added automatically when USB device was attached, they could've been missing in some other cases. The logic is now fixed so there are always USB controllers, even if there was none of them in the specified XML. - Limits for RPC messages were increased Hitting the RPC limits we have is easier every day, so they were increased once again and some guessing logic was improved as well. It is now possible to get more stats than ever using the virConnectGetAllDomainStats() call and push through even bigger requests and replies for all APIs. * Bug fixes - qemu: Create memory_backing_dir on startup Libvirt's policy is that directories are created on startup if they don't exist. We've missed this one. - PCIe 4.0 cards now report proper link speeds It could happen that the link speed for PCIe devices was not properly reported or the nodedev-dumpxml just failed. That was due to mistake in the field width, but should now work properly. - qemu: Do not report errors on shutdown For some users, in some rare cases, it could happen that there was an error message "internal error: End of file from qemu monitor" in the logs even though no problem happened. The detection of these false positives was improved and such errors should not show any more. - User-specified UNIX socket paths for virtio channels should not be reset It could happen, in some cases, that libvirt would mistake a user-specified path for its own generated one and thus remove it from the XML. The detection of such addresses was improved now. - Fix address reservation during RNG hot-plug When error occurred in a specific point in time during the hot-plug of an RNG device, it could happen that an address was released even though another device was already using it, making it possible to hot-plug another device with that address, effectively having duplicated addresses in the XML. Thanks everybody for your help with the release, be it code, reviews, bug reports, doc, etc! Enjoy !

So as planned I tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Everything seems to work fine for me with RC1 on my limited testing but as usual please give it some attention to find out issues and check portability on the various platforms. If everything woks well, I will push the RC2 on Tuesday and then we can roll out 3.4.0 and get out of the freeze next Thursday, but in the meantime, please give it a try !

[Libvirt-announce] Release of libvirt-3.3.0
by Daniel Veillard 06 May '17

06 May '17

I did the release yesterday evening, just sending this mail now. The release has been tagged in git, I have pushed signed tarball and rpms to the usual place at : ftp://libvirt.org/libvirt/ I also pushed version 3.3.0 of the python bindings, same tagged in git and signed tarball and rpms should be in their respective place: ftp://libvirt.org/libvirt/python/ this is a balanced release with a fair amount of both new features and improvements, in addition to a set of bug fixes: * New features - net: Add support for coalesce settings Enabling data batching through these settings can improve network performance for guests. - qemu: Add support for guest CPU cache specification This features allows fine-grained control of the cache behavior of the guest CPU. - qemu: Add support for the qemu-xhci USB controller * Improvements - hyperv: Support Hyper-V 2012 and newer Starting with Hyper-V 2012 the API has changed causing the existing driver to be unable to send and process requests properly. This has been resolved by adding abstractions to handle the differences and ease handling such breaks if they happen in the future. - libxl: Add support for nested HVM domains Xen has supported nested HVM domains since version 4.4. The libvirt libxl driver now supports nested HVM domains by specifying the host-passthrough CPU mode when defining a domain. - qemu: Implement ACPI support for aarch64 guests Up until this point, ACPI support was only advertised for x86_64 guests and disabling it for aarch64 guests was not possible at all. - vz: Add support for changing the number of vCPUs - qemu: Automatically choose the best USB controller for guests The recently introduced qemu-xhci USB controller is the best choice for both ppc64 and aarch64 guests, so use it by default on those architectures if available. - daemon: Increase default task limit for libvirtd The default number of tasks for the pids cgroup controller is 512, which libvirtd can quickly bump into when starting lots of guests. Raise the limit to a more reasonable 32768. - docs: Include man pages describing key code names and values - virsh: Report initialization errors Sometimes virsh might be unable to start: when that happens, report useful diagnostics instead of failing silently. * Bug fixes - nss: Don't require a network restart for libvirt_guest Previously, the libvirt_guest NSS module would only work properly after the corresponding network had been restarted; now newly started guests will be reported correctly right away. - storage: Remove unavailable transient pools after restart Solve an issue where transient storage pools would be stuck in an unmanageable state if the source disappeared and libvirtd was subsequently restarted. - storage: Fix capacity value for LUKS encrypted volumes The 'capacity' value (e.g. guest logical size) for a LUKS volume is smaller than the 'physical' value of the file in the file system, so we need to account for that. - qemu: Fix regression when hyperv/vendor_id feature is used Guests using the feature would not be started at all; it is now possible to start them as expected. - qemu: Do not crash on USB address with no port and invalid bus - crypto: Always pad data before encrypting it If this step is not performed, when the data length matches the chunk size the decryption routines will misinterpret the last byte of data as the padding length and fail to decode it correctly. Thanks everybody for your help toward this release, be it with patches, documentation, bug reports, reviews ideas, etc ... Enjoy !
