[libvirt] [PATCH 00/15] qemu: Implement non-shared storage migration via TLS (blockdev-add saga)

[Peter Krempa]

Implement the non-shared storage migration when TLS is enabled. This is
done by using blockdev-add to add the NBD endpoint with the TLS
environment alias configured properly.

Peter Krempa (15):
  qemu: block: Don't nest storage layer properties into format layer
  conf: domain: Export virDomainStorageSourceParse
  qemu: migration: Don't access disk members without lock
  qemu: caps: Add capability for blockdev-add/blockdev-del
  qemu: monitor: Factor out and document code to format QMP command
  qemu: monitor: Add implementation for blockdev-add and blockdev-del
  qemu: monitor: Introduce support for blockdev-mirror
  qemu: block: Add helpers for hot-adding virStorageSource via blockdev
  qemu: domain: Extract NBD disk migration private data formatting
  qemu: domain: Extract parsing of NBD status XML
  qemu: domain: Add private data for NBD migration storage source
    definition
  test: Add status XML test for NBD tls storage migration
  qemu: migration: Rename NBD migration functions
  qemu: migration: Extract code responsible for calling drive-mirror
  qemu: migration: Add support for transporting NBD over TLS
