[libvirt] [PATCH] qemu: Use iohelper during restore
by Shivaprasad G Bhat 07 Jul '17

07 Jul '17

Commit afe6e58 & c4caab53 made necessary changes to use io-helpers during save and restore. The commit c4caab53 missed to remove the redundant check in qemuDomainSaveImageOpen() because of which virFileWrapperFdNew() is not called if bypass_cache is false.

[libvirt] [PATCH v3 00/26] Multiple PHBs and hostdev isolation for pSeries guests
by Andrea Bolognani 07 Jul '17

07 Jul '17

Changes from [v2]: * support hot(un)plug properly; * add documentation. Changes from [v1]: * address review comments; * implement a much better isolation algorithm that doesn't require parsing and formatting the isolation group and can handle more dynamic scenarios, such as empty PHBs changing their isolation groups to accomodate hotplugged hostdevs; * add more test cases. Known limitations: * hostdevs in IOMMU group 0 are not handled properly - the default isolation group is currently 0, which means hostdevs in IOMMU group 0 will be assigned addresses as if they were emulated devices and will not be isolated properly. Fixing this will be a lot of work because it requires cleaning up the the code that instantiates pretty much anything embedding a virDomainDeviceInfo, which is... A lot of things. Luckily, IOMMU group 0 will probably not contain any devices that are actually usable as hostdevs, so it should be okay to fix this in a follow-up series rather than upfront. Reviewed-by tags have been collected, so figuring out which patches are still in need of reviewing is pretty easy.

[libvirt] Entering freeze for libvirt-3.5.0
by Daniel Veillard 06 Jul '17

06 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] libvirt binding for DBUS
by Pavel Hrdina 06 Jul '17

06 Jul '17

Hi, Last week (Jun 26 - Jun 30) there was a Cockpit Hackfest and the main topic was integration virtualization support into Cockpit. For that purpose Lars and me have started to work on a new libvirt dbus binding. Currently the binding is written manually and only few APIs are supported, however the ultimate goal is to write a code generator and ensure that all APIs are covered by this binding (similarly to the python binding). Dan, can you please setup hosting on libvirt.org? The binding is experimental and the API may and probably will change until first official release. Thanks, Pavel [1] <https://github.com/larskarlitski/libvirt-dbus>

[libvirt] Release of libvirt-3.5.0
by Daniel Veillard 05 Jul '17

05 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 !
