[libvirt] [PATCH 0/5] Introduce VIR_CONNECT_GET_ALL_DOMAINS_STATS_BEST_EFFORT
by Michal Privoznik 15 Jun '18

15 Jun '18

Problem is, if there is a long standing job on a domain fetching statistics might hiccup which might be a problem for mgmt apps that query stats every few seconds. Orthogonal to this, I think we should break our sync QEMU_JOB_* into two separate jobs: one for qemu monitor the other for qemu guest agent. Problem is, if thread A grabs QEMU_JOB_MODIFY and talks only to guest agent it prevents thread B from grabbing QEMU_JOB_QUERY which wants to talk only to qemu monitor. But this is a different can of worms and I haven't thought it through completely just yet.

Re: [libvirt] [PATCH v4 3/3] hw/vfio/display: add ramfb support

Using a different device here seems like it almost guarantees a very complicated path to support under libvirt. What necessitates this versus a simple ramfb=on option to vfio-pci? I'm also not sure I understand the usage model, SeaBIOS and OVMF know how to write to this display, but it seems that the guest does not. I suppose in the UEFI case runtime services can be used to continue writing this display, but BIOS doesn't have such an option, unless we're somehow emulating VGA here. So for UEFI, I can imagine this covers us from power on through firmware boot and up to guest drivers initializing the GPU (assuming the vGPU supports a kernel mode driver, does NVIDIA?), but for BIOS it seems we likely still have a break from the bootloader to GPU driver initialization. For instance, what driver is used to draw the boot animation (or blue screen) on SeaBIOS Windows VM? I'm assuming that this display and the vGPU display are one in the same, so there's some cut from one to the other.

[libvirt] [dbus PATCH v2 00/17] StorageVolume APIs
by Katerina Koukiou 14 Jun '18

14 Jun '18

Changes from v1: - Fixes from reviews - And more: * tests: Moved all xml definitions for tests in separate file. * tests: Renamed all functions that are not supposed to be run as tests, so that they don't have test prefix. I found out that these were running as tests, when I added the new function for listing the volumes from the test driver. test driver doesn't offer any volumes, and the function failed. * tests: To get a test volume I created a pytest fixture, which I add in the setup of the tests that are manipulating with volumes. In this way, the get_test_storage_volume function remained same to the similar purpose functions as suggested in the previous review. Katerina Koukiou (17): Introduce StorageVol Interface Implement ListStorageVolumes for StoragePool Interface test: move XML definition of entities to seperate file tests: rename test_* functions which are not tests Implement StorageVolCreateXML method for StoragePool Interface Implement Name property for StorageVol Interface Implement Key property for StorageVol Interface Implement Path property for StorageVol Interface Implement GetXMLDesc method for StorageVol Interface Implement StorageVolLookupByKey method for Connect Interface Implement StorageVolLookupByName method for StoragePool Interface Implement StorageVolLookupByPath method for Connect Interface Implement Resize method for StorageVol Interface Implement Wipe method for StorageVol Interface Implement GetInfo method for StorageVol Interface Implement Delete method for StorageVol Interface Implement StorageVolCreateXMLFrom method for StoragePool Interface data/Makefile.am | 4 +- data/org.libvirt.Connect.xml | 12 ++ data/org.libvirt.StoragePool.xml | 28 ++++ data/org.libvirt.StorageVol.xml | 51 +++++++ src/Makefile.am | 4 +- src/connect.c | 66 +++++++++ src/connect.h | 1 + src/storagepool.c | 152 ++++++++++++++++++++ src/storagevol.c | 302 +++++++++++++++++++++++++++++++++++++++ src/storagevol.h | 9 ++ src/util.c | 35 +++++ src/util.h | 16 +++ tests/libvirttest.py | 37 ++++- tests/test_connect.py | 69 ++++----- tests/test_domain.py | 20 +-- tests/test_network.py | 14 +- tests/test_storage.py | 79 ++++++++-- tests/xmldata.py | 47 ++++++ 18 files changed, 871 insertions(+), 75 deletions(-) create mode 100644 data/org.libvirt.StorageVol.xml create mode 100644 src/storagevol.c create mode 100644 src/storagevol.h create mode 100644 tests/xmldata.py -- 2.15.0

[libvirt] [PATCH v4 0/2] Finish the conversion to virConfGetValue* functions
by Fabiano Fidêncio 14 Jun '18

14 Jun '18

This patchset finishes the conversion to virConfGetValue* functions, started by Daniel Berrange a few months ago. Please, mind that although we could make virConfGetValue* functions more generic in order to support numbers and booleans as strings, that doesn't seem the safest path to take. The side-effect of this is that we will have to live with some specific code doing that as part of vmx and xen_common. Once this patchset gets merged, https://wiki.libvirt.org/page/BiteSizedTasks#Finish_conversion_to_virConfGe… can be removed. - Changes since v1: All the "values" from virConfGetValueString() are freed - Changes since v2: All comments from Ján Tomko have been addressed; A few leaks were (possibly) found and they're addressed in the last patch of the series; - Changes since v3: All commentes from Ján Tomko have been addressed in order to lower the non-whitespace changes in the first patch; Fabiano Fidêncio (2): xen_common: Split per-Vif logic from xenParseVif() xen_common: convert to typesafe virConf acessors src/xenconfig/xen_common.c | 535 +++++++++++++++++++++++---------------------- 1 file changed, 273 insertions(+), 262 deletions(-) -- 2.14.3
