[libvirt] [PATCH] qemu: Properly check for incoming migration job
by Jiri Denemark 31 Jul '15

31 Jul '15

In addition to checking the current asynchronous job qemuMigrationJobIsActive reports an error if the current job does not match the one we asked for. Let's just check the job directly since we are not interested in the error in qemuProcessHandleMonitorEOF.

[libvirt] [sandbox PATCH 00/11] Virt-sandbox-image
by Eren Yagdiran 31 Jul '15

31 Jul '15

Hello, virt-sandbox-image.py is a python script that lets you download and run templates from supported sources using virt-sandbox. Component-based archictecture is accomplished through Source base class. Docker image support is added through DockerSource. DockerSource is capable of downloading and running Docker images by consuming Docker Registry API. Daniel P Berrange (1): Add virt-sandbox-image Eren Yagdiran (10): Fix virt-sandbox-image Image: Add Hooking Mechanism Image: Add download function Image: Refactor create function Image: Add delete function Image: Add get_command function to Source Image: Add run args Image: Add check_driver function Image: Add get_disk function to Source Image: Add run function po/POTFILES.in | 1 + virt-sandbox-image/sources/DockerSource.py | 364 +++++++++++++++++++++++++++++ virt-sandbox-image/sources/Source.py | 27 +++ virt-sandbox-image/virt-sandbox-image.py | 233 ++++++++++++++++++ 4 files changed, 625 insertions(+) create mode 100644 virt-sandbox-image/sources/DockerSource.py create mode 100644 virt-sandbox-image/sources/Source.py create mode 100644 virt-sandbox-image/virt-sandbox-image.py -- 2.1.0

[libvirt] Entering freeze for libvirt-1.2.18
by Daniel Veillard 31 Jul '15

31 Jul '15

As planned and after pushing the small fix for the 'make dist' issue I have tagged in git the candidate release 1 and pushed signed tarballs and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work so far for me, please give it a try ! I think I will push rc2 on Wed or Thu and have the release over next week-end, Play with it, thanks !

[libvirt] [PATCH 0/2] Disable floppy disk for PowerPC VMs
by Kothapally Madhu Pavan 30 Jul '15

30 Jul '15

This is an attempt to fix: Libvirt BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1180486 Libvirt currently assumes ISA_based floppy disks to be available across all architectures and machine types. However, PowerPC Book 3S compatible ('ie pseries) virtual machines do not support Floppy disks. This patch series prevents libvirt from launching ppc64[le] -based 'pseries' VMs with floppy devices. --- Kothapally Madhu Pavan (2): Caps: Disable floppy disk for PowerPC Vm Avoid starting a PowerPC VM with floppy disk src/conf/domain_conf.c | 19 +++++++++++++---- src/qemu/qemu_capabilities.c | 15 ++++++++++--- src/qemu/qemu_command.c | 47 ++++++++++++++++++++++++++++++++++++++++-- 3 files changed, 71 insertions(+), 10 deletions(-) --

[libvirt] [PATCH v10 0/5] nodeinfo: Add support for subcores
by Andrea Bolognani 30 Jul '15

30 Jul '15

Only patch 1/5 has been updated, all the other patches are the same as v8: 2/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01045.html 3/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01048.html 4/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01049.html 5/5 https://www.redhat.com/archives/libvir-list/2015-July/msg01050.html I'm including the full history below. Cheers. Changes in v10: * don't attempt to close a file that wasn't opened * report a detailed error to help with diagnosis Changes in v9: * take into account the fact that kvm might not be loaded or even installed Changes in v8: * shortened test names so that make dist doesn't stop working again Changes in v7: * rebased on top of master now that the series this one builds on have been merged Changes in v6: * updated to work on top of [PATCH v2 00/10] nodeinfo: Various cleanups Changes in v5: * streamlined the logic used to decide whether the subcore configuration is valid and moved it to a separate function * split the tests into separate commits for easier review and to hopefully avoid having trouble with the list due to the message size Changes in v4: * removed a printf() statement * fixed typo in a commit message Changes in v3: * the function to get the number of threads per subcore has been moved to the from virarch.c, which deals with architecture names only and is therefore not the right place to read host configuration, to nodeinfo.c where the rest of this stuff lives * said function has also been given a shorter name * the "valid subcore mode" boolean has been removed: threads_per_subcore will be a positive number if subcores should be taken into account, and if that's not the case (x86 host, tainted configuration) it will simply be zero, so now the code needs to keep track of a single variable instead of two * the test case has been renamed to be more descriptive * the test data has been cleaned up by removing all cpu/cpu*/node* links, which prevented 'make dist' from working due to recursive linking Andrea Bolognani (3): tests: Add subcores1 nodeinfo test tests: Add subcores2 nodeinfo test tests: Add subcores3 nodeinfo test Shivaprasad G Bhat (2): nodeinfo: Fix output on PPC64 KVM hosts tests: Prepare for subcore tests src/libvirt_private.syms | 1 + src/nodeinfo.c | 159 ++++++++++++++++++++- src/nodeinfo.h | 1 + tests/Makefile.am | 6 + [...] tests/nodeinfomock.c | 35 +++++ tests/nodeinfotest.c | 8 +- 1348 files changed, 2140 insertions(+), 6 deletions(-) [...] create mode 100644 tests/nodeinfomock.c -- 2.4.3
