[libvirt PATCH v2 0/3] Add script to sync from QEMU i386 cpu models
by Tim Wiederhake
This hopefully makes synchronization with QEMU faster and less
error prone.
Patch #3 showcases the changes to the cpu models the script
suggests for qemu 8d90bfc5c31ad60f6049dd39be636b06bc00b652.
V1: https://www.redhat.com/archives/libvir-list/2020-October/msg01008.html
Changes since last version:
* Use apostrophes instead of quotation marks in XML.
Tim Wiederhake (3):
cpu_map: Unify apostrophe and quotation mark usage
cpu_map: Add script to sync from QEMU i386 cpu models
[DONTMERGE] Sample output of new sync script

[PATCH] security: Use org namespace for xattrs on macOS
by Roman Bolshakov
There're no guidelines on what namespace should be used but it seems
thirdparty apps can select the one they like [1], i.e. freedekstop
xattrs are prefixed with xdg.
qemusecuritytest passes after that.

[PATCH-for-5.2 v3] hw/mips: Remove the 'r4k' machine
by Philippe Mathieu-Daudé
We deprecated the support for the 'r4k' machine for the 5.0 release
(commit d32dc61421), which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.
To repeat the rationale from the deprecation note:
- this virtual machine has no specification
- the Linux kernel dropped support for it 10 years ago
Users are recommended to use the Malta board instead.

Release of libvirt-6.9.0
by Jiri Denemark
The 6.9.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at
https://libvirt.org/sources/
https://libvirt.org/sources/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing any other feedback. Your work is
greatly appreciated.
* New features
* nodedev: Add support for channel subsystem (CSS) devices on S390
A CSS device is represented as a parent device of a CCW device.
This support allows to create vfio-ccw mediated devices with
``virNodeDeviceCreateXML()``.
* qemu: Implement memory failure event
New event is implemented that is emitted whenever a guest encounters a
memory failure.
* qemu: Implement support for ``<transient/>`` disks
VMs based on the QEMU hypervisor now can use ``<transient/>`` option for
local file-backed disks to configure a disk which discards changes made to
it while the VM was active.
* hyperv: implement new APIs
The ``virConnectGetCapabilities()``, ``virConnectGetMaxVcpus()``,
``virConnectGetVersion()``, ``virDomainGetAutostart()``,
``virDomainSetAutostart()``, ``virNodeGetFreeMemory()``,
``virDomainReboot()``, ``virDomainReset()``, ``virDomainShutdown()``, and
``virDomainShutdownFlags()`` APIs have been implemented in the Hyper-V
driver.
* bhyve: implement virtio-9p filesystem support
Implement virito-9p shared filesystem using the ``<filesystem/>`` element.
* qemu: Add support for vDPA network devices.
VMs using the QEMU hypervisor can now specify vDPA network devices
using ``<interface type='vdpa'>``. The node device APIs also now
list and provide XML descriptions for vDPA devices.
* Improvements
* Bug fixes
* hyperv: ensure WQL queries work in all locales
Relying on the "Description" field caused queries to fail on non-"en-US"
systems. The queries have been updated to avoid using localized strings.
* rpc: Fix ``virt-ssh-helper`` detection
libvirt 6.8.0 failed to correctly detect the availability of the new
``virt-ssh-helper`` command on the remote host, and thus always used the
fallback instead; this has now been fixed.
Enjoy.

hyperv: g_autofree username and password in hypervConnectOpen()
hyperv: remove spaces after hypervObject* casts
hyperv: WMI class list function general cleanup
hyperv: move hypervGetWmiClass to hyperv_wmi.h
hyperv: move hypervGetProcSDByVSSDInstanceId to hyperv_wmi.c
hyperv: consistent names for SettingData functions
hyperv: minor formatting fix in hyperv_wmi.h
hyperv: call openwsman's ws_serializer_free_mem

Call for Volunteers: Summaries of a few KVMForum-2020 talks for an LWN article
by Kashyap Chamarthy
Hi, folks
Like last year[1], we're aiming to submit a KVM Forum 2020 "recap"
article for LWN.
This won't be a comprehensive summary of a lot of talks — LWN normally
aims for 1500 words; they say "fewer can sometimes work, and more is
generally OK too". Given that, the write-up can cover about four
topics, similar to previous year's recap.
So I'm looking for a couple of volunteers. Meanwhile, I'll write LWN
folks an email to see if they're amenable to this. If they can't accept
it for some reason, Plan-B is qemu.org blog articles.
- KVM Forum 2020 schedule: https://kvmforum2020.sched.com/
- And LWN.net's author guidelines: https://lwn.net/op/AuthorGuide.lwn
I volunteer to summarize Janosch Frank's "The Common Challenges of
Secure VMs" talk.
Let me know, on-list or off-list, on what topic you'd like to pick.
PS: Just like it was noted in the last year's call for volunteers, we
will not ask LWN.net for money.

[PATCH-for-5.2] hw/mips: Remove the 'r4k' machine
by Philippe Mathieu-Daudé
We deprecated the support for the 'r4k' machine for the 5.0 release
(commit d32dc61421), which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.
To repeat the rationale from the deprecation note:
- this virtual machine has no specification
- the Linux kernel dropped support for it 10 years ago
Users are recommended to use the Malta board instead.

[PATCH] virDomainNetDefParseXML: Fix error message for unknown value of //mac/@type
by Michal Privoznik
In v6.6.0-rc1~124 we've introduced a new mechanism for MAC
addresses for ESX: ignore all checks (type='static') that libvirt
or ESX would do (and possibly fail) for specified MAC address.
Accepted values for the @type attribute are "generated" and
"static". But the error message mentions a different attribute.
Fixes 454e5961abf40c14f8b6d7ee216229e68fd170bf
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1892130
