[libvirt] [PATCH] qemuProcessLaunch: Return earlier if spawning qemu failed
by Michal Privoznik
If spawning qemu fails then we report an error and proceed to
writing status XML onto the disk. This is unnecessary as we are
sure that the domain is not running.
At the same time, if virPidFileReadPath() fails it returns
-errno. Use it in the error message. It may explain what went
wrong.

[libvirt] [security-notice PATCH 0/9] various improvements to script for finding broken/fixed branches/tags
by Daniel P. Berrangé
This series provides for much greater automation when publishing
details of security flaws. It is now possible to just provide the broken
and fixed commit hash on the master branch. All the tag info and details
of branches are now filled in automatically.
Daniel P. Berrangé (9):
scripts: change data structures used to track branches & tags
scripts: report vulnerable branches which don't have any tags too
scripts: add ability to handle a fixed commit hash
scripts: change to update notice files inplace
scripts: allow for notices to have multiple commit hashes
scripts: optimize tag to branch mapping
scripts: add detection of cherry-picks in branches
scripts: fuzzy matching on subject to identify unannotated cherry
picks
notices: re-generate all branch/tag info

[libvirt] [PATCH v6 00/23] network: refactor to decouple virt drivers from network driver
by Daniel P. Berrangé
An update to
v1: https://www.redhat.com/archives/libvir-list/2018-December/msg00681.html
v2: https://www.redhat.com/archives/libvir-list/2019-February/msg01581.html
v3: https://www.redhat.com/archives/libvir-list/2019-March/msg01259.html
v4: https://www.redhat.com/archives/libvir-list/2019-April/msg01186.html
v5: https://www.redhat.com/archives/libvir-list/2019-May/msg00358.html
Currently the network driver registers a set of callbacks with the virt
driver in order to handle allocating/releasing network ports associated
with guest NICs.
This series introduces a virNetworkPortPtr object and associated XML
that describes a network port. The virt drivers now call public APIs
associated with this new object to create/delete ports for guest NICs.
Changed in v6:
- Fixed mistakes in RNG schema & example XML
- Fix docs typos
Changed in v5:
- Separately track ports with type=network vs type=bridge to deal with
fallout after reverting patches which merged them
- Add RNG schema and XML format docs
- Change to use classID attr on <bandwidth> isntead of
of separate <class id="xx"/> element
- Drop obsolete driver deps from RPM spec
- Other misc bug fixes found during testing
Changed in v4:
- Merged the ACKd patches which didn't depend on other un-acked
parts
- Improve bandwidth error messages
- Ensure we set floor sum to zero when starting network
- Misc fixes for previous review comments
NB, I have not added missing docs for the new XML doc format
yet. This is work in progress.
Changed in v3:
- Remove unused API symbol
- Fix dist of test data files
Changed in v2:
- Fix many bugs related to upgrades with running VMs
- Convert over bandwidth controls to the new APIs
- Handle reconnecting VIFs to bridges during startup
- Much much more that I can't remember
Daniel P. Berrangé (23):
conf: allow bandwidth parsing / formatting to include class ID
conf: introduce virNetworkPortDefPtr struct and XML support
network: make networkLogAllocation independent of domain conf
conf: add APIs to convert virDomainNetDef to virNetworkPortDef
network: convert networkAllocateActualDevice to virNetworkPortDef
network: convert networkNotifyActualDevice to virNetworkPortDef
network: convert networkReleaseActualDevice to virNetworkPortDef
network: convert hook script to take a network port XML
network: remove the virDomainNetBandwidthChangeAllowed callback
network: introduce networkAllocatePort
network: introduce networkNotifyPort
network: introduce networkReleasePort
network: introduce networkUpdatePortBandwidth
network: add public APIs for network port object
access: add permissions for network port objects
remote: add support for new network port APIs
virsh: add support for network port APIs
conf: support recording ports against virNetworkObjPtr
network: add implementation of network port APIs
lxc, libxl: notify network driver of NICs during reconnect
lxc, libxl: save domain status after reconnect
conf: record a portid against the domain conf
conf: switch over to use network port APIs for virt drivers

[libvirt] [PATCH v3 00/15] implement cgroups v2 support
by Pavel Hrdina
In cgroups v2 there is no devices controller, eBPF should be used
instead.
Changes in v3:
- removed workaround for kernel bug [1]
- added documentation how to get the eBPF program
Changes in v2:
- fixed build on bsd and older kernels without cgroup BPF
- cgroup bpf devices code moved to separate file
Documentation for eBPF:
<http://man7.org/linux/man-pages/man2/bpf.2.html>
<https://www.kernel.org/doc/Documentation/networking/filter.txt>
<https://docs.cilium.io/en/v1.3/bpf/>

[libvirt] [PATCH] test_driver: implement virDomainInterfaceAddresses
by Ilias Stamatis
Ignore @source in the case of the test driver and return fixed private
IPv4 addresses for all the interfaces defined in the domain.
Signed-off-by: Ilias Stamatis <stamatis.iliass(a)gmail.com>
---
The default config of the test driver has no guest interfaces defined,
so this must be tested with a custom config.
Maybe it would be a good idea to add one or more guest interfaces in the
default config. I could send an additional patch for this.

[libvirt] [PATCH v4 0/3] numa: deprecate '-numa node, mem' and default memory distribution
by Igor Mammedov
Changes since v3:
- simplify series by dropping idea of showing property values in "qom-list-properties"
and use MachineInfo in QAPI schema instead
Changes since v2:
- taking in account previous review, implement a way for mgmt to intospect if
'-numa node,mem' is supported by machine type as suggested by Daniel at
https://www.mail-archive.com/qemu-devel@nongnu.org/msg601220.html
* ammend "qom-list-properties" to show property values
* add "numa-mem-supported" machine property to reflect if '-numa node,mem=SZ'
is supported. It culd be used with '-machine none' or at runtime with
--preconfig before numa memory mapping are configured
* minor fixes to deprecation documentation mentioning "numa-mem-supported" property
1) "I'm considering to deprecating -mem-path/prealloc CLI options and replacing
them with a single memdev Machine property to allow interested users to pick
used backend for initial RAM (fixes mixed -mem-path+hostmem backends issues)
and as a transition step to modeling initial RAM as a Device instead of
(ab)using MemoryRegion APIs."
(for more details see: https://www.mail-archive.com/qemu-devel@nongnu.org/msg596314.html)
However there is a couple of roadblocks on the way (s390x and numa memory handling).
I think I finally thought out a way to hack s390x in migration compatible manner,
but I don't see any way to do it for -numa node,mem and default RAM assignement
to nodes. Considering both numa usecases aren't meaningfully using NUMA (aside
guest side testing) and could be replaced with explicitly used memdev parameter,
I'd like to propose removing these fake NUMA friends on new machine types,
hence this deprecation. And once the last machie type that supported the option
is removed we would be able to remove option altogether.
As result of removing deprecated options and replacing initial RAM allocation
with 'memdev's (1), QEMU will allocate guest RAM in consistent way, fixing mixed
use-case and allowing boards to move towards modelling initial RAM as Device(s).
Which in its own turn should allow to cleanup NUMA/HMP/memory accounting code
more by dropping ad-hoc node_mem tracking and reusing memory device enumeration
instead.

[libvirt] [PATCH v2] qemu: fix pr-helper0 remain
by Jie Wang
If libvirt receive DISCONNECTED event and set prDaemonRunning to false,
and qemuDomainRemoveDiskDevice is performing in the meantime.
qemuDomainRemoveDiskDevice will return directly by prDaemonRunning
check, so the pr-helper0 object will remain.
In that case we should try harder and also kill the pr-helper process,
so qemuProcessKillManagedPRDaemon could use the same treatment.
