[libvirt] [PATCH RFC 00/27] Native external gluster snapshots

This series refactors and fixes stuff needed to support snapshots on gluster-backed vm's. The series is marked as RFC as docs for some of the changes are missing and I'd like to start code review while I'll figure out the docs. Peter Krempa (27): DO NOT APPLY UPSTREAM: Reproducer for disk snapshot crash qemu: snapshot: Avoid libvirtd crash when qemu crashes while snapshotting Revert "DO NOT APPLY UPSTREAM: Reproducer for disk snapshot crash" Revert "storage: fix omitted slash in gluster volume URI" storage: gluster: Properly fix missing slashes in volume paths snapshot: schema: Split out snapshot disk driver definition snapshot: Add support for specifying snapshot disk backing type snapshot: Test snapshot disk type specification storage: Add gluster pool filter and fix virsh pool listing storage: Avoid forward declaration of virStorageVolDelete storage: fs: Fix comment for virStorageBackendFileSystemDelete storage: Support deletion of volumes on gluster pools storage: lvm: Avoid forward decl of virStorageBackendLogicalDeleteVol storage: LVM: Separate creating of the volume from building storage: disk: Separate creating of the volume from building storage: RBD: Separate creating of the volume from building storage: Sheepdog: Separate creating of the volume from building storage: Introduce internal pool support storage: Add new argument for createVol backend API storage: gluster: Introduce dummy functions for creating a volume storage: Improve error message when a storage backend is missing maint: Fix messy include of libvirt_internal.h storage: Add internal API to create temporary storage pools and vols storage: Implement ephemeral storage APIs for local disk volumes storage: gluster: Support conversion of gluster volumes to temp volumes qemu: snapshot: Switch snapshot file deletion to the new storage API qemu: snapshot: Add support for external active snapshots on gluster docs/hvsupport.pl | 3 + docs/schemas/domainsnapshot.rng | 94 +++- include/libvirt/libvirt.h.in | 1 + src/Makefile.am | 3 +- src/check-aclrules.pl | 3 + src/check-drivername.pl | 1 + src/conf/snapshot_conf.c | 25 +- src/conf/snapshot_conf.h | 15 +- src/conf/storage_conf.c | 7 +- src/conf/storage_conf.h | 1 + src/driver.h | 14 + src/internal.h | 2 - src/libvirt_internal.c | 71 +++ src/libvirt_internal.h | 22 + src/libvirt_private.syms | 3 + src/libxl/libxl_conf.h | 1 + src/lxc/lxc_conf.h | 1 + src/qemu/qemu_command.c | 2 +- src/qemu/qemu_command.h | 9 + src/qemu/qemu_driver.c | 274 +++++++++-- src/storage/storage_backend.c | 3 +- src/storage/storage_backend.h | 2 +- src/storage/storage_backend_disk.c | 47 +- src/storage/storage_backend_fs.c | 36 +- src/storage/storage_backend_gluster.c | 139 +++++- src/storage/storage_backend_logical.c | 129 ++--- src/storage/storage_backend_rbd.c | 42 +- src/storage/storage_backend_sheepdog.c | 32 +- src/storage/storage_driver.c | 597 +++++++++++++++++++---- src/uml/uml_conf.h | 1 + tests/domainsnapshotxml2xmlin/disk_snapshot.xml | 18 + tests/domainsnapshotxml2xmlout/disk_snapshot.xml | 18 + tools/virsh-pool.c | 9 +- 33 files changed, 1341 insertions(+), 284 deletions(-) create mode 100644 src/libvirt_internal.c -- 1.8.5.1
