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

[Peter Krempa]

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

  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
