[libvirt] [libvirt-go-xml PATCH] Make @Path of UNIX chr device source optional
by Erik Skultety 13 Mar '19

13 Mar '19

According to the libvirt RNG schema, @path is an optional attribute for the character source element, so we should be okay if it was omitted.

[libvirt] [PATCH v4 0/8] bulk snapshot list/redefine (incremental backup saga)
by Eric Blake 13 Mar '19

13 Mar '19

While looking at my work on incremental backups, Nir raised a good point: if we want to recreate a set of known checkpoints on one machine that will be taking over a domain from another machine, my initial proposal required making multiple API calls to list the XML for each checkpoint on the source, and then more API calls to redefine each checkpoint on the destination; it also had the drawback that the list has to be presented in topological order (the API won't let you define a child checkpoint if the parent is not defined first). He asked if I could instead add bulk APIs, for getting the XML for all checkpoints at once, and then for redefining all checkpoints at once. Since my checkpoint code borrows heavily from concepts in the snapshot code, I chose to tackle the problem by starting with this series, which does the same thing for snapshots as what I plan to do for checkpoints. That is, since this patch series adds 2 new APIs, the checkpoint series will do likewise with very similar code. I'm also toying with the idea of followup patches that store all snapshots alongside the persistent <domain> XML in a single file, rather than in one snapshot per <domainsnapshot> file (we'd still support reading from the old method at libvirtd startup, but would not need to output in that manner any more).

12 Mar '19

v2 of: https://www.redhat.com/archives/libvir-list/2019-February/msg01503.html As usual, you can find my patches at my github: https://github.com/zippy2/libvirt/commits/firmware_v2 diff to v1: - Hopefully all Lazlo's comment are worked in (fixing the logic that chooses suitable firmware for secboot/SMM domains, commit message adjustements, sanity check for parsed FW descriptions, etc.) - Added more debug messages around FW selection code, i.e. it'll be visible from the logs why given FS is not suitable (or that it is). Michal Prívozník (15): virmock: Initialize both symbols in VIR_MOCK_REAL_INIT_ALT qemu_domain: Separate NVRAM VAR store file name generation qemu_capabilities: Expose qemu <-> libvirt arch translators virDomainLoaderDefParseXML: Allow loader path to be NULL conf: Introduce VIR_DOMAIN_LOADER_TYPE_NONE conf: Introduce firmware attribute to <os/> qemu: Introduce basic skeleton for parsing firmware description test: Introduce qemufirmwaretest qemu_firmware: Introduce qemuFirmwareFetchConfigs qemufirmwaretest: Test qemuFirmwareFetchConfigs() qemu_firmware: Introduce qemuFirmwareFillDomain() qemu_process: Call qemuFirmwareFillDomain qemuDomainDefValidate: Don't require SMM if automatic firmware selection enabled qemu: Enable firmware autoselection qemuxml2argvtest: Test os.firmware autoselection docs/formatdomain.html.in | 22 +- docs/schemas/domaincommon.rng | 12 +- src/conf/domain_conf.c | 113 +- src/conf/domain_conf.h | 15 +- src/libvirt_private.syms | 2 + src/qemu/Makefile.inc.am | 2 + src/qemu/qemu_capabilities.c | 4 +- src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_command.c | 1 + src/qemu/qemu_domain.c | 34 +- src/qemu/qemu_domain.h | 4 + src/qemu/qemu_firmware.c | 1364 +++++++++++++++++ src/qemu/qemu_firmware.h | 50 + src/qemu/qemu_process.c | 5 + tests/Makefile.am | 14 +- tests/domaincapsschemadata/full.xml | 1 + .../etc/qemu/firmware/40-ovmf-sb-keys.json | 1 + .../etc/qemu/firmware/60-ovmf-sb.json | 0 .../user/.config/qemu/firmware/10-bios.json | 0 .../usr/share/qemu/firmware/40-bios.json | 35 + .../share/qemu/firmware/50-ovmf-sb-keys.json | 36 + .../usr/share/qemu/firmware/60-ovmf-sb.json | 35 + .../usr/share/qemu/firmware/61-ovmf.json | 33 + .../usr/share/qemu/firmware/70-aavmf.json | 35 + tests/qemufirmwaretest.c | 135 ++ ...arch64-os-firmware-efi.aarch64-latest.args | 37 + .../aarch64-os-firmware-efi.xml | 30 + .../os-firmware-bios.x86_64-latest.args | 39 + tests/qemuxml2argvdata/os-firmware-bios.xml | 68 + ...os-firmware-efi-secboot.x86_64-latest.args | 43 + .../os-firmware-efi-secboot.xml | 68 + .../os-firmware-efi.x86_64-latest.args | 42 + tests/qemuxml2argvdata/os-firmware-efi.xml | 68 + tests/qemuxml2argvtest.c | 17 + .../aarch64-os-firmware-efi.xml | 1 + tests/qemuxml2xmloutdata/os-firmware-bios.xml | 1 + .../os-firmware-efi-secboot.xml | 1 + tests/qemuxml2xmloutdata/os-firmware-efi.xml | 1 + tests/qemuxml2xmltest.c | 27 + tests/virmock.h | 5 +- 40 files changed, 2374 insertions(+), 30 deletions(-) create mode 100644 src/qemu/qemu_firmware.c create mode 100644 src/qemu/qemu_firmware.h create mode 120000 tests/qemufirmwaredata/etc/qemu/firmware/40-ovmf-sb-keys.json create mode 100644 tests/qemufirmwaredata/etc/qemu/firmware/60-ovmf-sb.json create mode 100644 tests/qemufirmwaredata/home/user/.config/qemu/firmware/10-bios.json create mode 100644 tests/qemufirmwaredata/usr/share/qemu/firmware/40-bios.json create mode 100644 tests/qemufirmwaredata/usr/share/qemu/firmware/50-ovmf-sb-keys.json create mode 100644 tests/qemufirmwaredata/usr/share/qemu/firmware/60-ovmf-sb.json create mode 100644 tests/qemufirmwaredata/usr/share/qemu/firmware/61-ovmf.json create mode 100644 tests/qemufirmwaredata/usr/share/qemu/firmware/70-aavmf.json create mode 100644 tests/qemufirmwaretest.c create mode 100644 tests/qemuxml2argvdata/aarch64-os-firmware-efi.aarch64-latest.args create mode 100644 tests/qemuxml2argvdata/aarch64-os-firmware-efi.xml create mode 100644 tests/qemuxml2argvdata/os-firmware-bios.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/os-firmware-bios.xml create mode 100644 tests/qemuxml2argvdata/os-firmware-efi-secboot.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/os-firmware-efi-secboot.xml create mode 100644 tests/qemuxml2argvdata/os-firmware-efi.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/os-firmware-efi.xml create mode 120000 tests/qemuxml2xmloutdata/aarch64-os-firmware-efi.xml create mode 120000 tests/qemuxml2xmloutdata/os-firmware-bios.xml create mode 120000 tests/qemuxml2xmloutdata/os-firmware-efi-secboot.xml create mode 120000 tests/qemuxml2xmloutdata/os-firmware-efi.xml -- 2.19.2

While working to add new API for bulk dumpxml/redefine, and turn virDomainSnapshotObjList into a base class for sharing with checkpoints, I realized how trivial it would be to take advantage of information already present on the server, instead of using a lot of CPU time with 'virsh snapshot-list --tree' to reconstruct a DAG on the client side.
