[PATCH v3] util: support PCI passthrough net device stats collection
by zhenwei pi
Collect PCI passthrough net device stats from kernel by netlink
API.
Currently, libvirt can not get PCI passthrough net device stats,
run command:
#virsh domifstat instance --interface=52:54:00:2d:b2:35
error: Failed to get interface stats instance 52:54:00:2d:b2:35
error: internal error: Interface name not provided
The PCI device(usually SR-IOV virtual function device) is detached
while it's used in PCI passthrough mode. And we can not parse this
device from /proc/net/dev any more.
In this patch, libvirt check net device is VF of not firstly, then
query virNetDevVFInterfaceStats(new API).
virNetDevVFInterfaceStats parses VFs info of all PFs, compares MAC
address until the two MAC addresses match.
'#ip -s link show' can get the same result. Instead of parsing the
output result, implement this feature by libnl API.
Notice that this feature deponds on driver of PF.
Test on Mellanox ConnectX-4 Lx, it works well.
Also test on Intel Corporation 82599ES, it works, but only get 0.
(ip-link command get the same result).
IFLA_VF_STATS is supported since Linux-4.2, suggested by Laine,
just using defined(__linux__) && WITH_LIBNL is enough.

[libvirt PATCH v3 0/8] Make unknown XML elements fail CPU comparison
by Tim Wiederhake
We currently ignore unknown elements in the CPU XML description, e.g.
with virsh cpu-compare and hypervisor-cpu-compare. This makes
'<cpu><faeture name="..."/></cpu>' (note the typo in "faeture")
semantically identic to '<cpu/>'. No error is reported.
This series adds checks for unrecognized attributes and elements in
the "<cpu>" element, catching this kind of mistake.

[PATCH V4] Modify virCPUarmCompare to perform compare actions
by Zhenyu Zheng
Modify virCPUarmCompare in cpu_arm.c to perform compare action.
This patch only adds host to host CPU compare, the rest cases
remains the same. This is useful for source and destination host
compare during migrations to avoid migration between different
CPU models that have different CPU freatures.

[PATCH] rpm: Simplify qemu+kvm conditionals and eliminate duplication
by Neal Gompa
The conditionals for enabling qemu+kvm were unnecessarily complex.
In practice, there were far fewer cases where the functionality would
be disabled than what the conditional logic expressed, and this change
simplifies it to the realistic set of options.

[libvirt PATCH v4 0/6] Add support for vDPA network devices
by Jonathon Jongsma
vDPA network devices allow high-performance networking in a virtual machine by
providing a wire-speed data path. These devices require a vendor-specific host
driver but the data path follows the virtio specification.
The support for vDPA devices was recently added to qemu. This allows
libvirt to support these devices. This patchset requires that the device is
configured on the host with the appropriate vendor-specific driver. This will
create a chardev on the host at e.g. /dev/vhost-vdpa-0. That chardev path can
then be used to define a new interface with type=3D'vdpa'.
Changes in v4:
- rebased to latest master
- added hotplug support
- report vdpa devices in node device list
Jonathon Jongsma (6):
conf: Add support for vDPA network devices
qemu: add vhost-vdpa capability
qemu: add vdpa support
qemu: add monitor functions for handling file descriptors
qemu: support hotplug of vdpa devices
Include vdpa devices in node device list

[PATCH 0/9] various build flag related fixes
by Laine Stump
These patches eliminate a few build flags that were necessary back 10
years ago when their associated features had been newly added to the
kernel, but are now pointless (because all supported Linuxes have the
feature) (1-6), makes it possible to to a successful (and usable,
albeit limited in some ways) build on a system that doesn't have
libnl3-devel installed (7-8) (macvtap and interface type='hostdev'
don't work, but standard tap devices do), and removes a duplicated
identifier check that I noticed in meson.build (9).
Laine Stump (9):
util: remove useless check for IFLA_VF_MAX
util: remove extraneous defined(__linux__) when checking for
WITH_LIBNL
build: eliminate useless WITH_VIRTUALPORT check
build: remove check for MACVLAN_MODE_PASSTHRU
build: simplify check for WITH_MACVTAP
build: eliminate WITH_MACVTAP flag
util: fix Linux build when libnl-devel isn't available
util: provide non-netlink/libnl alternative for virNetDevGetMaster()
build: remove duplicate check for GET_VLAN_VID_CMD

[PATCH 0/3] logging: fix a couple of issues
by Nikolay Shirokovskiy
The code fixed in the first actual patch is quite venerable so I made up
a synthetic test to show issue/test it is fixed. Test covers both issues.
Initially I got /tmp/virtlogd-test size of only 2048 and after the first
fix I saw actual endless loop.
Nikolay Shirokovskiy (3):
DO NOT APPLY: code to show logging issues
logging: read all bytes on EOF in event handler
logging: fix endless loop on EOF
