[libvirt] [PATCH 0/6] Split the storage file driver impls from the storage driver backends
by Daniel P. Berrangé 03 May '18

03 May '18

The storage driver backends currently register storage file backends as a side effect of initialization. This is fine right now while both run in the same libvirtd process, but in future the storage file backends will need to run in the hypervisor daemon which will be separate from the storage daemon. This small series splits them, makin the storage file backends be registered "on demand" Daniel P. Berrangé (6): util: create new virmodule.{c,h} files for dlopen support code storage: split gluster storage file code from storage driver backend storage: split fs storage file code from storage driver backend storage: fix virStorageFileGetBackingStoreStr error handling util: refactor storage file checks to allow error reporting storage: create separate loadable modules for storage file drivers libvirt.spec.in | 4 + src/driver.c | 133 +----------- src/driver.h | 3 - src/libvirt_driver_modules.syms | 1 - src/libvirt_private.syms | 3 + src/qemu/qemu_domain.c | 21 +- src/qemu/qemu_driver.c | 21 +- src/storage/Makefile.inc.am | 44 ++++ src/storage/storage_backend.c | 3 +- src/storage/storage_backend_fs.c | 210 +------------------ src/storage/storage_backend_gluster.c | 305 +--------------------------- src/storage/storage_backend_gluster.h | 2 +- src/storage/storage_file_fs.c | 251 +++++++++++++++++++++++ src/storage/storage_file_fs.h | 29 +++ src/storage/storage_file_gluster.c | 366 ++++++++++++++++++++++++++++++++++ src/storage/storage_file_gluster.h | 27 +++ src/util/Makefile.inc.am | 2 + src/util/virmodule.c | 163 +++++++++++++++ src/util/virmodule.h | 29 +++ src/util/virstoragefile.c | 123 ++++++++---- src/util/virstoragefile.h | 9 +- src/util/virstoragefilebackend.c | 72 +++++-- src/util/virstoragefilebackend.h | 9 +- 23 files changed, 1098 insertions(+), 732 deletions(-) create mode 100644 src/storage/storage_file_fs.c create mode 100644 src/storage/storage_file_fs.h create mode 100644 src/storage/storage_file_gluster.c create mode 100644 src/storage/storage_file_gluster.h create mode 100644 src/util/virmodule.c create mode 100644 src/util/virmodule.h -- 2.14.3

[libvirt] [GSoC] Introduction - nodejs bindings
by Ramy Elkest 03 May '18

03 May '18

Hi all, As a quick introduction, I'm Ramy Elkest, a student at Georgia Tech and one of the lucky ones selected by libvirt for this year's Google Summer of Code. During the next months I'll be working with my mentors Martin Kletzander and Erik Skultety to introduce nodejs to libvirt's family of bindings. In short, the aim is to generate the nodejs bindings from the XMLs (as we do for python). On a very high level my current approach is as follows: - Re-use libvirt-python's generator (mainly the parser) possibly re-written in node (TBD) - Draw from existing projects (eg. node-libvirt) to generate preliminary templates There are a few things to look into before jumping in: - Code generation framework (or lack of) - Node Abstractions for Node (NAN) vs. Node-API (N-API) If you have preliminary thoughts / background info about any of the above, I'd love to hear it. I'm usually around on irc, "relkest". Ramy

[libvirt] [PATCH v2 REBASE] lib: provide error message in new blockjob event
by Nikolay Shirokovskiy 03 May '18

03 May '18

If block job is completed with error qemu additionally provides error message. This patch introduces new event VIR_DOMAIN_EVENT_ID_BLOCK_JOB_ERROR to pass error message to client. This error message has no semantics and should not be interpreted. API and RPC layer also have reserved 'code' field to pass semantics loaded error code value in the future. Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com> --- Diff from v1 [1]: - replace block job event version 3 with block job error event - add code field to API/RPC to pass error code in the future Peter, I decided not to use enum/union as this looks like to much effort to extend code generation for this simple case. Using typed params looks unsuitable too.

[libvirt] [PATCH 00/35] qemu: Add formatting of JSON objects for -blockdev (blockdev-add saga)
by Peter Krempa 03 May '18

03 May '18

Diff to the RFC posting: - host_device and host_cdrom handling was added - modified code to format and parse node-names to status XML so that we can add other node names easier (for quorum, throttling, etc) - added test case for host_device Kevin, please sanity check the outputs whether they make sense. Thanks. Peter Krempa (35): storage: Properly track that backing chain members are readonly qemu: domain: Format storage source node names into private data util: storage: Add shadow copies of few disk properties to virStorageSource qemu: domain: Carefuly transfer configuration from disk to storage source qemu: block: Extract formatting of props for 'file' backend qemu: block: Handle iomode property for json 'file' driver utils: storage: Mark that a virStorageSource is going to be used as a floppy qemu: Move virtual FAT disk validation from command line builder qemu: block: Add support for accessing directories via the 'vvfat' driver util: file: Use only one #ifdef for __linux__ util: file: Add helper to determine whether a path is a CDROM qemu: domain: Store whether a virStorageSource is a host CDROM drive qemu: block: Properly handle block storage in JSON generator qemu: block: Propagate 'legacy' parameter when formatting disk backing qemu: block: Validate node-names for use with qemu qemu: block: Format cache modes for disk storage backends qemu: block: Format 'read-only' attribute for JSON disk protocol qemu: block: Always set discard for storage nodes qemu: block: Add support for creating 'format' layer for blockdev-add tests: qemublock: Rename variables in anticipation of new tests tests: Makefile: Sanitize entry for qemublocktest qemu: domain: Export qemuDomainDeviceDefValidateDisk qemu: domain: Tolerate NULL 'cfg' in qemuDomainPrepareDiskSourceChain tests: qemublock: Add testing of blockdev JSON property generator tests: qemublock: Add basic
