[libvirt] [PATCH v2 0/8] Fix some issues with rng grammar for output XML's,
by John Ferlan
v1: https://www.redhat.com/archives/libvir-list/2018-May/msg01455.html
Update patches to add data into schema for examples that I could generate.
For the vpxmigr and vzmigr, I wasn't sure what the capabilityschemadata
should look like, so I left those out. Those are only validate in the
"right" environment when virCapabilitiesAddHostMigrateTransport is called.
John Ferlan (8):
schema: Add physical sizing grammer for storagevol grammar
schema: Remove xenmigr from host migrate transport capability
schema,tests: Use vpxmigr for host migrate transport capability
schema: Add rdma for host migrate transport capability
schema: Add vzmigr for host migrate transport capability
schema: Add microcode to capability grammar
schema: Fix capability grammar for pagesElem
schema: Add missing block data for nodedev

[libvirt] [REPOSTv2 PATCH v3 0/6] Add support for VM Generation ID (vmgenid)
by John Ferlan
Second reposting of:
https://www.redhat.com/archives/libvir-list/2018-May/msg00813.html
To update patches with more conflicts for patch 2 (capabilities) and
patch 6 (news)
Cover from the v3 posting:
v2: https://www.redhat.com/archives/libvir-list/2018-April/msg02234.html
Changes since v2:
* Essentially handle comments from code review of original series from
comments received for patch 6:
https://www.redhat.com/archives/libvir-list/2018-April/msg02240.html
It's a somewhat simplified approach removing the ABI checks and the
adjustment to the genid value as part of domain def copy.
* (NEW) Patch 5 - add a 'genid' domain capability (similar to how Cole
added support for vmcoreinfo). Since the apps need a way to determine
whether this is enabled, this seems to be the best way.
John Ferlan (6):
conf: Add VM Generation ID parse/format support
qemu: Add VM Generation ID device capability
qemu: Alter VM Generation ID for specific startup/launch transitions
qemu: Add VM Generation ID to qemu command line
domcaps: Add 'genid' to domain capabilities
docs: Add news article for VM Generation ID

[libvirt] [PATCH] disk: Allow settling to occur after reading partitions
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1400475
In order to avoid a possible error as a result of kernel interactions
with the partition helper, let's use virWaitForDevices to force things
to settle down before attempting to open and read the partition. This
is related to https://bugzilla.redhat.com/show_bug.cgi?id=1264719.

NB: This also resolves issues seen while testing the patch with using
pool-refresh "frequently" on the disk pool. Perhaps the timing of
things has changed enough that it'd be see more often now. At least
with the f26 test system I used.
BTW: The other option proposed long ago, but rejected was adding
a timeout loop. I've also run the python script from the other
bz with 100% success.

[libvirt] [qemu PATCH v2] docs/interop: add "firmware.json"
by Laszlo Ersek
Add a schema that describes the different uses and properties of virtual
machine firmware.
Each firmware executable installed on a host system should come with at
least one JSON file that conforms to this schema. Each file informs the
management applications about
- the firmware's properties and one possible use case / feature set,
- configuration bits that are required to run the firmware binary.
In addition, define rules for management apps for picking the highest
priority firmware JSON file when multiple such files match the search
criteria.

RFCv3:
- Previous version (RFCv2) was posted at:
<http://mid.mail-archive.com/20180417224054.26363-1-lersek@redhat.com>
- Trim the CC list a little.
- Wrap to a 72-char margin, for an easier reading. [Markus]
- Run spell-checker. [Markus]
- Rename @FirmwareType to @FirmwareOSInterface, to better express the
concept. Update the enum constants accordingly (incl. documentation);
in particular replace @slof with @openfirmware. Rename the @type field
in @Firmware to @interface-type. [David, Gerd, Paolo, Thomas]
- Better yet, rename @interface-type to @interface-types (plural), and
turn it into a list of @FirmwareOSInterface entries, to express an
ordered compat list with multiple firmware<->OS interface types. [Dan,
Eric, Gerd, Paolo]
- Drop @FirmwareArchitecture, and switch the type of
@FirmwareTarget.@architecture to @SysEmuTarget (now defined in
"common.json"). [Dan, Gerd, Markus]
- Switch elements of @FirmwareTarget.@machines from aliases ("pc",
"q35", "virt") to concrete machine types, with glob patterns
understood. [Dan, Gerd]
- Rename @secure-boot-enrolled-keys to @enrolled-keys, and drop the
dependency on @secure-boot in its documentation. [Gerd]
- Describe the firmware JSON directories and the search rules to
management apps, under the @Firmware element. Relatedly, remove the
language on any concrete certificates under @enrolled-keys, as these
can be customized through the overrides. Also refresh the commit
message. [Dan, Gerd]
- Rename @pathname fields to @filename. [Markus]
- Don't replace "@executable.@filename" with "@executable.filename"
(that is, keep the second @ sign), because removing the 2nd @ sign
messes up the documentation ("filename" stops being type-set in
monospace in the HTML, for example). [Markus]
- Rename @nvram_template to @nvram-template. [Thomas]
- Keep @x-check-firmware for a while longer. [Dan, Gerd, Markus, Paolo]
RFCv2:
- previous version (RFCv1) was posted at
<http://mid.mail-archive.com/20180407000117.25640-1-lersek@redhat.com>
- v2 is basically a rewrite from scratch, starting out with Dan's
definitions from
<http://mid.mail-archive.com/20180410102033.GL5155@redhat.com> and
<http://mid.mail-archive.com/20180410110357.GP5155@redhat.com>,
hopefully addressing others' feedback as well
RFCv1:
- Folks on the CC list, please try to see if the suggested schema is
flexible enough to describe the virtual firmware(s) that you are
familiar with. Thanks!

+# ICH9-LPC.disable_s4=1".
+#
+# @amd-sev: The firmware supports running under AMD Secure Encrypted
+# Virtualization, as specified in the AMD64 Architecture
+# Programmer's Manual. QEMU command line options related to
+# this feature are documented in
+# "docs/amd-memory-encryption.txt".
+#
+# @enrolled-keys: The variable store (NVRAM) template associated with
+# the firmware binary has the UEFI Secure Boot
+# operational mode turned on, with certificates
+# enrolled.
+#
+# @requires-smm: The firmware requires the platform to emulate SMM
+# (System Management Mode), as defined in the AMD64
+# Architecture Programmer's Manual, and in the Intel(R)64
+# and IA-32 Architectures Software Developer's Manual. On
+# the "pc-q35-*" machine types of the @i386 and @x86_64
+# emulation targets, SMM emulation can be enabled with
+# "-machine smm=on". (On the "pc-q35-*" machine types of
+# the @i386 emulation target, @requires-smm presents
+# further CPU requirements; one combination known to work
+# is "-cpu coreduo,-nx".) If the firmware is marked as
+# both @secure-boot and @requires-smm, then write
+# accesses to the pflash chip (NVRAM) that holds the UEFI
+# variable store must be restricted to code that executes
+# in SMM, using the additional option "-global
+# driver=cfi.pflash01,property=secure,value=on".
+# Furthermore, a large guest-physical address space
+# (comprising guest RAM, memory hotplug range, and 64-bit
+# PCI MMIO aperture), and/or a high VCPU count, may
+# present high SMRAM requirements from the firmware. On
+# the "pc-q35-*" machine types of the @i386 and @x86_64
+# emulation targets, the SMRAM size may be increased
+# above the default 16MB with the "-global
+# mch.extended-tseg-mbytes=uint16" option. As a rule of
+# thumb, the default 16MB size suffices for 1TB of
+# guest-phys address space and a few tens of VCPUs; for
+# every further TB of guest-phys address space, add 8MB
+# of SMRAM. 48MB should suffice for 4TB of guest-phys
+# address space and 2-3 hundred VCPUs.
+#
+# @secure-boot: The firmware implements the software interfaces for UEFI
+# Secure Boot, as defined in the UEFI specification. Note
+# that without @requires-smm, guest code running with
+# kernel privileges can undermine the security of Secure
+# Boot.
+#

+# @Firmware:
+#
+# Describes a firmware (or a firmware use case) to management software.
+#
+# It is possible for multiple @Firmware elements to match the search
+# criteria of management software. Applications thus need rules to pick
+# one of the many matches, and users need the ability to override distro
+# defaults.
+#
+# It is recommended to create firmware JSON files (each containing a
+# single @Firmware root element) with a double-digit prefix, for example
+# "50-ovmf.json", "50-seabios-256k.json", etc, so they can be sorted in
+# predictable order. The firmware JSON files should be searched for in
+# three directories:
+#
+# - /usr/share/qemu/firmware -- populated by distro-provided firmware
+# packages (XDG_DATA_DIRS covers
+# /usr/share by default),
+#
+# - /etc/qemu/firmware -- exclusively for sysadmins' local additions,
+#
+# - $XDG_CONFIG_HOME/qemu/firmware -- exclusively for per-user local
+# additions (XDG_CONFIG_HOME
+# defaults to $HOME/.config).
+#
+# Top-down, the list of directories goes from general to specific.
+#
+# Management software should build a list of files from all three
+# locations, then sort the list by filename (i.e., last pathname
+# component). Management software should choose the first JSON file on
+# the sorted list that matches the search criteria. If a more specific
+# directory has a file with same name as a less specific directory, then
+# the file in the more specific directory takes effect. If the more
+# specific file is zero length, it hides the less specific one.
+#
+# For example, if a distro ships
+#
+# - /usr/share/qemu/firmware/50-ovmf.json
+#
+# - /usr/share/qemu/firmware/50-seabios-256k.json
+#
+# then the sysadmin can prevent the default OVMF being used at all with
+#
+# $ touch /etc/qemu/firmware/50-ovmf.json
+#
+# The sysadmin can replace/alter the distro default OVMF with
+#
+# $ vim /etc/qemu/firmware/50-ovmf.json
+#
+# or they can provide a parallel OVMF with higher priority
+#
+# $ vim /etc/qemu/firmware/10-ovmf.json
+#
+# or they can provide a parallel OVMF with lower priority
+#
+# $ vim /etc/qemu/firmware/99-ovmf.json
+#
+# @description: Provides a human-readable description of the firmware.
+# Management software may or may not display @description.
+#
+# @interface-types: Lists the types of interfaces that the firmware can
+# expose to the guest OS. This is a non-empty, ordered
+# list; entries near the beginning of @interface-types
+# are considered more native to the firmware, and/or
+# to have a higher quality implementation in the
+# firmware, than entries near the end of
+# @interface-types.
+#
+# @mapping: Describes the loading / mapping properties of the firmware.
+#
+# @targets: Collects the target architectures (QEMU system emulators)
+# and their machine types that may execute the firmware.
+#
+# @features: Lists the features that the firmware supports, and the
+# platform requirements it presents.
+#
+# @tags: A list of auxiliary strings associated with the firmware for
+# which @description is not appropriate, due to the latter's
+# possible exposure to the end-user. @tags serves development and
+# debugging purposes only, and management software shall
+# explicitly ignore it.

[libvirt] [PATCH 0/5] qemu: refactor device post parse callback
by Peter Krempa
Main idea was to split the disk code since I'll be changing it later but
as I was at it I refactored everything.
Peter Krempa (5):
qemu: domain: Extract disk post parse code into a function
qemu: domain: Extract network device def post parse code
qemu: domain: Extract video device def post parse code
qemu: domain: Extract panic device def post parse code
qemu: domain: Use typecasted enum in qemuDomainDeviceDefPostParse
