[libvirt] [PATCH 0/5] Introduce VIR_CONNECT_GET_ALL_DOMAINS_STATS_BEST_EFFORT
by Michal Privoznik
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. Thanks,
Alex

[libvirt] [dbus PATCH v2 00/17] StorageVolume APIs
by Katerina Koukiou
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

[libvirt] [PATCH v4 0/2] Finish the conversion to virConfGetValue* functions
by Fabiano Fidêncio
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_virConf...
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;
