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.

[libvirt] [REPOSTv2 PATCH v3 0/6] Add support for VM Generation ID (vmgenid)
by John Ferlan 25 May '18

25 May '18

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.

[libvirt] [PATCH] disk: Allow settling to occur after reading partitions
by John Ferlan 25 May '18

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.

[libvirt] [qemu PATCH v2] docs/interop: add "firmware.json"
by Laszlo Ersek 25 May '18

25 May '18

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. Cc: "Daniel P.

[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.

On +# the "pc-q35-*" machine types of the @i386 and @x86_64 +# emulation targets, SMM emulation can be enabled with +# "-machine smm=on".

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. +# +# @verbose-dynamic: When firmware log capture is enabled, the firmware +# logs a large amount of debug messages, which may +# impact boot performance. With log capture disabled, +# there is no boot performance impact. On the +# "pc-i440fx-*" and "pc-q35-*" machine types of the +# @i386 and @x86_64 emulation targets, firmware log +# capture can be enabled with the QEMU command line +# options "-chardev file,id=fwdebug,path=LOGFILEPATH +# -device isa-debugcon,iobase=0x402,chardev=fwdebug". +# @verbose-dynamic is mutually exclusive with +# @verbose-static. +# +# @verbose-static: The firmware unconditionally produces a large amount +# of debug messages, which may impact boot performance. +# This feature may typically be carried by certain UEFI +# firmware for the "virt-*" machine types of the @arm +# and @aarch64 emulation targets, where the debug +# messages are written to the first (always present) +# PL011 UART. @verbose-static is mutually exclusive +# with @verbose-dynamic. +# +# Since: 2.13 +## +{ 'enum' : 'FirmwareFeature', + 'data' : [ 'acpi-s3', 'acpi-s4', 'amd-sev', 'enrolled-keys', + 'requires-smm', 'secure-boot', 'verbose-dynamic', + 'verbose-static' ] } + +## +# @FirmwareFlashFile: +# +# Defines common properties that are necessary for loading a firmware +# file into a pflash chip.

[libvirt] [PATCH 0/5] qemu: refactor device post parse callback
by Peter Krempa 25 May '18

25 May '18

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 src/qemu/qemu_domain.c | 219 ++++++++++++++++++++++++++++++++----------------- 1 file changed, 144 insertions(+), 75 deletions(-) -- 2.16.2
