[libvirt] [PATCH] virstoragefile: identify GPFS as cluster FS
by Diego Michelotto
GPFS is 'IBM General Parallel File System', also called
'IBM Spectrum Scale', stalls when a process issues a lot
of fsyncs in a short timeframe.
It is better if the VM I/O is not synchronous.
It is racommended to use writeback caching policy.
In order to permit that it is added VIR_FILE_SHFS_GPFS to
the list of shared file systems in virStorageFileIsClusterFS
function.

[libvirt] [PATCH] conf: fix title and description for virDomainSetMetadata API
by Pavel Hrdina
If we pass XML to virDomainDefineXML API with these two elements:
...
<title></title>
<description></description>
...
libvirt correctly ignores these two elements and they will not appear
in the parsed XML.
However, if we use virDomainSetMetadata API and with "" as value for
title or description we will end up with the parsed XML that contains
these empty elements.
Let's fix the behavior of this API to behave the same as
virDomainDefineXML.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1518042

[libvirt] [PATCH 0/2] ui: support for authorization control on TLS connections
by Daniel P. Berrangé
This series provides the VNC parts of the authorization control series
previously posted as:
v1: https://lists.gnu.org/archive/html/qemu-devel/2018-06/msg04482.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2018-06/msg05727.html
v3: https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg01639.html
v4: https://lists.gnu.org/archive/html/qemu-devel/2019-02/msg04319.html
The core authz framework is now merged & these patches have all had
positive review. Thus these VNC parts are ready to go into the VNC
maintainer's tree, should the maintainer consider them acceptable.
Note the 2nd patch is modifying the HMP, but I considered it part
of ui/vnc, since that's the only bit of QEMU which ever used these
HMP commands, and it has a dependancy on the first patch merging
first.

[libvirt] [PATCH 00/10] domcaps: use virTristateBool
by Cole Robinson
Extending domaincapabilities with new XML schema is currently a bit of
a maintenance pain. Consider the case of adding a new enum for listing
<sound> models. I want to output this info for the qemu driver.
Internally in the domaincapabilities plumbing, whether a <device> is
supported= is tracked with boolean true/false. If I extend that
pattern for <sound> devices and fill in data for the qemu driver, the
other domcaps implementations will now automatically output a new XML
element:
<sound supported='no'>
Now, for bhyve I can 'git grep' confirm that it doesn't have any
<sound> support, but for xen/libxl it _is_ supported. So if I don't
fill in accurate support in the xen driver, I've just made their
domcaps report blatantly incorrect info.
Ideally I would make these <sound> changes and the other drivers output
would _not_ change. xen output would now be incomplete, but not
obviously wrong, which is easier on me the developer, and safer for the
API consumer.
This moves domcaps plumbing in that direction. It switches most
internal 'supported' fields to virTristateBool so we can track an
ABSENT state and map that to outputting no XML. Explicit supported='no'
values are filled in where needed to ensure existing driver XML doesn't
change. cpu and sev supported= values are left unconverted, but they
require semi-special handling anyways so aren't really affected by the
problem I laid out above.

[libvirt] [PATCH v2 00/17] Add support to list Storage Driver backend capabilities
by John Ferlan
v1: https://www.redhat.com/archives/libvir-list/2019-January/msg00479.html
Changes since v1:
* The first 4 patches were already R-by'd and pushed.
* From v1, rework patch 5 & 6 into what now is patches 8 & 9. The
format of the output for what results in the output for the
connectGetCapabilities (virConnectGetCapabilities).
* From v1, drop patch 7
* In v2, patches 1-7 are new as a result of work done for patches 10-17.
patches 1-5 were posted upstream, but left unreviewed:
https://www.redhat.com/archives/libvir-list/2019-February/msg00333.html
These essentially ensure the volOptions and poolOptions don't list
or use something unexpected per documentation. The doc patch is a
simple update to add some missing text and fix an entry
* Patches 10-17 are new to implement the ability to get/format the
Storage Driver backend capabilities via:
storageConnectGetStoragePoolCapabilities
virConnectGetStoragePoolCapabilities
similar to how virConnectGetDomainCapabilities returns domain specific
output. The output is essentially what is provided in the poolOptions
and volOptions from storage_conf as valid values for format type fields
for pool and/or volume as well as an enumerated list for the required
source elements for creation. Whether the latter is useful or not was
not clear, but since it is something that can cause a creation error
when missing, I figured it'd be useful. The new virsh command follows
then domcapabilities nomenclature.

[libvirt] [PATCH for-4.0 v4 0/2] virtio: Provide version-specific variants of virtio PCI devices
by Eduardo Habkost
Existing modern-only device types are not being touched by v3, as
they don't need separate variants. However, I plan to implement
separate cleanups in the code that calls virtio_pci_force_virtio_1(),
first, and then propose additional changes (e.g. deprecating
disable-legacy and disable-modern in those device types).
Changes v3 -> v4:
* Trivial comment fixes (Cornelia Huck)
* Test code update (Caio Carrara)
Changes v2 -> v3:
* Split into two separate patches (type registration helper
and introduction of new types)
* Rewrote virtio_pci_types_register() completely:
* Replaced magic generation of type names with explicit fields in
VirtioPCIDeviceTypeInfo
* Removed modern_only field (not necessary anymore)
* Don't register a separate base type unless necessary
Changes v1 -> v2:
* Removed *-0.9 devices. Nobody will want to use them, if
transitional devices work with legacy drivers
(Gerd Hoffmann, Michael S. Tsirkin)
* Drop virtio version from name: rename -1.0-transitional to
-transitional (Michael S. Tsirkin)
* Renamed -1.0 to -non-transitional
* Don't add any extra variants to modern-only device types
(they don't need it)
* Fix typo on TYPE_VIRTIO_INPUT_HOST_PCI (crash reported by
Cornelia Huck)
* No need to change cast macros for modern-only devices
* Rename virtio_register_types() to virtio_pci_types_register()
Original patch description:
Many of the current virtio-*-pci device types actually represent
3 different types of devices:
* virtio 1.0 non-transitional devices
* virtio 1.0 transitional devices
* virtio 0.9 ("legacy device" in virtio 1.0 terminology)
That would be just an annoyance if it didn't break our device/bus
compatibility QMP interfaces. With this multi-purpose device
type, there's no way to tell management software that
transitional devices and legacy devices require a Conventional
PCI bus.
The multi-purpose device types would also prevent us from telling
management software what's the PCI vendor/device ID for them,
because their PCI IDs change at runtime depending on the bus
where they were plugged.
This patch adds separate device types for each of those virtio
device flavors:
* virtio-*-pci: the existing multi-purpose device types
* virtio-*-pci-transitional: virtio-1.0 device supporting legacy drivers
* virtio-*-pci-non-transitional: modern-only
Reference to previous discussion that originated this idea:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg558389.html
