[libvirt] [PATCH v2] spec: drop anything older than Fedora 13

by Eric Blake

RHEL 5 is based on libvirt 0.8.2, as was Fedora 13. RHEL 5 also happens to be the oldest box that we actively support with a buildbot, so it is time to clean up some crufty conditionals in the spec file that no longer are necessary for modern Fedora. Although it is probably okay to make further simplifications to a newer minimum Fedora version, that can be done as a later patch. This patch just focuses on cleaning any comparison of %{?fedora} that will always be true or false once we assume a minimum of F13. * libvirt.spec.in: Make with_audit default to on. Move other conditionals to a single RHEL-5 block. Simplify any fedora comparison older than 13. Document our assumptions.

[libvirt] [RFC PATCH 0/5] add virDomainBlockCopy API

by Eric Blake

Patch series is not complete yet, but I'm posting the front end now to get feedback on whether it has a chance of being included in 1.2.8. Still to go: patch 6 will actually implement the new function in qemu driver, by parsing a <disk> XML snippet into a virStorageSource; patch 7 will add monitor support for the qemu 1.4 parameters of granularity and buffer size. Individual commit messages should give more hints on where I'm taking this series. Ultimately, I'm hoping that Peter's work on gluster backends for block commit can be expanded into also covering gluster backends for the copy destination.

[libvirt] [PATCH] daemon: Fix option -v missing info priority log

by Wang Rui

From: Zhou Yimin <zhouyimin(a)huawei.com> Introduce by 63fbcc692. When start libvirtd with commandline "/usr/sbin/libvirtd -d -l -v", we expect verbose(info level) log if neither environment variable nor config file about logging controls is set. But in fact we can't get any info priority log in the default output file. The log priority of default output is VIR_LOG_DEFAULT(VIR_LOG_WARN), so the info log is filtered out. To record info priority log we must parse option -v before setting the default output. After this patch, we get all verbose log in the default output file.

[libvirt] [RFCv2] Introduce API for retrieving bulk domain stats v2

by Peter Krempa

I'd like to propose a (hopefully) fairly future-proof API to retrieve various statistics for domains. The motivation is that management layers that use libvirt usually poll libvirt for statistics using various split up APIs we currently provide. To get all the necessary stuff, the mgmt app need to issue Ndomains * Napis calls and cope with the various returned formats. The APIs I'm wanting to introduce here will: 1) Return data in a format that we can expand in the future and is hierarchical. This version returns the data as typed parameters where the fields are constructed as dot-separated strings containing names and other stuff in a list of typed params. 2) Stats for multiple (all) domains can be queried at once and are returned in one call. This will allow to decrease the overhead necessary to issue multiple calls per domain multiplied by the count of domains. 3) Selectable (bit mask) fields in the returned format. This will allow to retrieve only specific stats according to the APPs need. Initially the implementation will introduce the option to retrieve block, interface and cpu stats with the possibility to add more in the future. The stats groups will be enabled using a bit field @stats passed as the function argument. A few groups for inspiration: VIR_DOMAIN_STATS_STATE VIR_DOMAIN_STATS_CPU VIR_DOMAIN_STATS_BLOCK VIR_DOMAIN_STATS_INTERFACE the returned typed params will use the following scheme state.state = running state.reason = started cpu.count = 8 cpu.0.state = running cpu.0.time = 1234 ... I'm also thinking of doing an async version of this, where the user would provide a callback that would be called for each returned domain but I'm not quite sure if that would play nicely with our RPC so that requires a bit more investigation first.
