[libvirt] [PATCH 0/2] Adding reflink support for XFS and others.

by Julio Faracco

This serie add XFS library to use the macro for reflink (clone). This is the case where BTRFS is not available but XFS is. In case of both is unavailable, the code will use FICLONE from filesystem library if it is defined. This implementation is similar to copy command. If you run a copy and trace the syscalls, you will see that ioctl uses BTRFS_IOC_CLONE or FICLONE to create a reflink.

[libvirt] [PATCH python] fix build with older libvirt missing virNWFilterBindingPtr

by Daniel P. Berrangé

While we correctly disable all public API bindings that rely on virNWFilterBindingPtr, the generator is still creating a helper function that needs it - libvirt_virNWFilterBinding_pointer. Making this helper conditional is a little hairy, so just provide a trivial typedef to keep it happy. Signed-off-by: Daniel P.

[libvirt] [PATCH] examples: Remove config.h from hellolibvirt and openauth

These two examples do not use any definition from config.h, and by removing it these examples can be compiled standalone. Signed-off-by: Marcos Paulo de Souza <marcos.souza.org(a)gmail.com> --- When trying to remove config.h from domtop and domsuspend, a later inclusion of unistd.h complains about the missing config.h.

[libvirt] [PATCH 0/2] Minor fixes for virTypedParams(De)Serialize

by Marc Hartmayer

Some minor fixes and two questions: * Is the first method, which is described in the documentation for virTypedParamsDeserialize, in sync with the actual code? ("Older APIs do not rely on deserializer allocating memory for @params, ...") * Do we also have to set *nparams = 0 in case of an error and the user has allocated the memory?

[libvirt] [RFCv2 PATCH 0/5] Introduce RDT memory bandwidth allocation support

by bing.niu＠intel.com

From: Bing Niu <bing.niu(a)intel.com> This series is to introduce RDT memory bandwidth allocation support by extending current virresctrl implementation. The Memory Bandwidth Allocation (MBA) feature provides indirect and approximate control over memory bandwidth available per-core. This feature provides a method to control applications which may be over-utilizing bandwidth relative to their priority in environments such as the data-center. The details can be found in Intel's SDM 17.19.7. Kernel supports MBA through resctrl file system same as CAT. Each resctrl group have a MB parameter to control how much memory bandwidth it can utilize in unit of percentage. In this series, MBA is enabled by enhancing existing virresctrl implementation. The policy employed for MBA is similar with CAT: The sum of each MBA group's bandwidth dose not exceed 100%. The enhancement of virresctrl include two parts: Part 1: Add two new structures virResctrlInfoMB and virResctrlAllocMB for collecting host system MBA capability and domain memory bandwidth allocation. Those two structures are the extension of existing virResctrlInfo and virResctrlAlloc. With them, virresctrl framework can support MBA and CAT concurrently. Each virResctrlAlloc represent a resource allocation including CAT, or MBA, or CAT&MBA. The policy of MBA is that: total memory bandwidth of each resctrl group, created by virresctrl, does not exceed to 100%. Part 2: On XML part, add new elements to host capabilities query and domain allocation to support memory bandwidth allocation. ---------------------------------------------------------------------------------------------- For host capabilities XML, new XML format like below example, <host> ..... <memory> <node id='0' cpus='0-19'> <control granularity='10' min ='10' maxAllocs='8'/> </node> </memory> </host> granularity --- memory bandwidth granularity min --- minimum memory bandwidth allowed maxAllocs --- maximum concurrent memory bandwidth allocation allowed. ---------------------------------------------------------------------------------------------- For domain XML, new format as below example <domain type='kvm' id='2'> ...... <cputune> ...... <shares>1024</shares> <memorytune vcpus='0-1'> <node id='0' bandwidth='20'/> </memorytune> </cputune> ...... </domain> id --- node where memory bandwidth allocation will happen bandwidth --- bandwidth allocated in percentage ---------------------------------------------------------------------------------------------- Changelog: v1->v2: Jano's comment: 1. put renaming parts into separated patches. 2. set the initial return value as -1. 3. using full name in structure definition. 4. do not use VIR_CACHE_TYPE_LAST for memory bandwidth allocation formatting. Pavel's comment: 1. add host capabilities XML for memory bandwidth allocation. 2. do not mix use cachetune section in XML for memory bandwidth allocation in domain XML. define a dedicated one for memory bandwidth allocation.

[libvirt] [PATCH 0/9] Resolve libvirtd hang on termination with connected long running client

by John Ferlan

RFC: https://www.redhat.com/archives/libvir-list/2018-January/msg00318.html Adjustments since RFC... Patches 1&2: No change, were already R-B'd Patch 3: Removed code as noted in code review, update commit message Patch 4: From old series removed, see below for more details Patch 9: no change NB: Patches 5-8 and 10 from Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com> are removed as they seemed to not be necessary Replaced the former patch 4 with series of patches to (slowly) provide support to disable new connections, handle removing waiting jobs, causing the waiting workers to quit, and allow any running jobs to complete. As it turns out, waiting for running jobs to complete cannot be done from the virNetServerClose callbacks because that means the event loop processing done during virNetServerRun will not allow any currently long running worker job thread a means to complete. So when virNetDaemonQuit is called as a result of the libvirtd signal handlers for SIG{QUIT|INT|TERM}, instead of just causing virNetServerRun to quit immediately, alter to using a quitRequested flag and then use that quitRequested flag to check for long running worker threads before causing the event loop to quit resulting in libvirtd being able to run through the virNetDaemonClose processing.

[libvirt] [PATCHv1 00/12] BaselineHypervisorCPU using QEMU QMP exchanges

by Chris Venteicher

Some architectures (S390) depend on QEMU to compute baseline CPU model and expand a models feature set. Interacting with QEMU requires starting the QEMU process and completing one or more query-cpu-model-baseline QMP exchanges with QEMU in addition to a query-cpu-model-expansion QMP exchange to expand all features in the model. See "s390x CPU models: exposing features" patch set on Qemu-devel for discussion of QEMU aspects.
