[libvirt] [PATCH 00/35] qemu: Add formatting of JSON objects for -blockdev (blockdev-add saga)
by Peter Krempa 03 May '18

03 May '18

Diff to the RFC posting: - host_device and host_cdrom handling was added - modified code to format and parse node-names to status XML so that we can add other node names easier (for quorum, throttling, etc) - added test case for host_device Kevin, please sanity check the outputs whether they make sense. Thanks. Peter Krempa (35): storage: Properly track that backing chain members are readonly qemu: domain: Format storage source node names into private data util: storage: Add shadow copies of few disk properties to virStorageSource qemu: domain: Carefuly transfer configuration from disk to storage source qemu: block: Extract formatting of props for 'file' backend qemu: block: Handle iomode property for json 'file' driver utils: storage: Mark that a virStorageSource is going to be used as a floppy qemu: Move virtual FAT disk validation from command line builder qemu: block: Add support for accessing directories via the 'vvfat' driver util: file: Use only one #ifdef for __linux__ util: file: Add helper to determine whether a path is a CDROM qemu: domain: Store whether a virStorageSource is a host CDROM drive qemu: block: Properly handle block storage in JSON generator qemu: block: Propagate 'legacy' parameter when formatting disk backing qemu: block: Validate node-names for use with qemu qemu: block: Format cache modes for disk storage backends qemu: block: Format 'read-only' attribute for JSON disk protocol qemu: block: Always set discard for storage nodes qemu: block: Add

[libvirt] [PATCH] util: Clean up consumers of virJSONValueArraySize
by John Ferlan 03 May '18

03 May '18

Rather than have virJSONValueArraySize return a -1 when the input is not an array and then splat an error message, let's check for an array before calling and then change the return to be a size_t instead of ssize_t. That means using the helper virJSONValueIsArray as well as using a more generic error message such as "Malformed <something> array". In some cases we can remove stack variables and when we cannot, those variables should be size_t not ssize_t. Alter a few references of if (!value) to be if (value == 0) instead as well. Some callers can already assume an array is being worked on based on the previous call, so there's less to do.

[libvirt] 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/
