[PATCH 00/10] qemu: Fix pre-creation of non-shared storage on migration
by Peter Krempa
The last patch fixes a bug where we'd fail to detect capacity of disks
on migration source due to changes in disk topology related to blockdev.
The rest of the series makes the function at least somewhat sane.
Peter Krempa (10):
util: hash: Use g_new0 for allocating hash internals
conf: domain: Remove checking of return value of virHashCreateFull
Remove checking of return value of virHashNew
qemuMigrationCookieAddNBD: Exit early if there are no disks
qemuMigrationCookieNBD: Extract embedded struct
qemuMigrationCookieAddNBD: Use glib memory allocators
qemuMigrationCookieAddNBD: Move monitor call out of the loop
qemuMigrationCookieAddNBD: Use virHashNew and automatic freeing of
virHashTablePtr
qemuMigrationCookieAddNBD: Remove 'ret' variable and 'cleanup' label
qemuMigrationCookieAddNBD: Fix filling of 'capacity' when blockdev is
used

[PATCH v2 00/21] PCI Multifunction hotplug/hotunplug support
by Daniel Henrique Barboza
This series adds PCI multifunction hotplug/unplug capabilities
for Libvirt. Some of these patches were sent last year in a
shorter prep series in [1]. The patches then got a bit of
rework to keep up with Libvirt changes in master. This
work follows the considerations made for the unplug design
in [2]. A first version of this series were sent back in
2018 [3], so this is the official version 2 of that work.
The design guideline for the patches can be summed up as:
- attach/detach functions were changed to handle a list of
devices instead of a single device definition. The regular
device attach/detach is represented with a list with
size = 1;
- common code between single device and multifunction device
mechanics were moved to 'internal' versions of the functions;
- for the 'Live' operations, both attach and detach were
handled in specialized functions for the multifunction case.
The regular case is still being handled by the same
functions.
This allowed us to add the multifunction support without
changing existing regular attach/detach device support.
Attaching/detaching a multifunction device works by supplying
the <devices> XML to the same attach/detach commands we
already use. It is expected to supply the same XML when
detaching the device, as discussed in [2].
Despite the changes and additions I've made, this is still
adherent to the original 2018 series from Shivaprasad G Bhat.

[libvirt-rust PATCH v3 0/4] Map more functions in stream module
by Zixing Liu
This set of patches will add more functions to the Rust bindings.
Newly mapped functions from C library: virStreamNew virStreamEventUpdateCallback virStreamEventRemoveCallback virStreamEventAddCallback.
virStreamEventAddCallback can accept normal fn functions or closures (can capture variables outside)
The changes are not very thoroughly tested since event module is not implemented at all so the virStreamEventAddCallback will always return "unsupported by the connection driver".
Version 2: Addressed comments
Version 3: Undo format changes and rebased against latest branch
Zixing Liu (4):

[PATCH v3 0/4] lxc: Add suport to network indexes for LXC 3.X
by Julio Faracco
This series implement support for network syntax settings for LXC 3.X.
Now, indexes are part of the settings to define network interfaces. Each
interface has its own index. The old style uses 'type' tag to
differentiate each interface and with this, it could use one single
structure. Now, network interfaces are a single array with interface
pointers.
Old:
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = virbr0
New:
lxc.net.0.type = veth
lxc.net.0.flags = up
lxc.net.0.link = virbr0
v1-v2: Moving sscanf to virStrToLong_ull according Daniel's suggestion.
v2-v3: Adding missing g_autofree from `suffix` variable.
Julio Faracco (4):
lxc: refactor lxcNetworkParseData pointers to use new structures
lxc: add LXC version 3 network parser
lxc: remove domain definition from lxc network struct
tests: update LXC config dataset to support V3 indexes

[PATCH] libxl: support getting and setting parameters for the Credit2
by Dario Faggioli
With Credit2 being Xen default scheduler, it's definitely the case to
allow Credit2's scheduling parameters to be get and set via libvirt.
This is easy, as Credit and Credit2 have (at least as of now) the very
same parameters ('weight' and 'cap'). So we can just let credit2 pass
the scheduler-type check and the same code will work for both.
