[libvirt] [PATCH v3 0/5] Guest filesystem information API

[Tomoki Sekiyama]

Hi,

This is v3 of patchset to add virDomainGetFSInfo API.

* changes in v2->v3:
 -[all] squashed fixup patches by John Ferlan (thanks!)
 -[all] added 'ndevAlias' filed instead of NULL-termination of devAlias
 -[all] renamed 'type' field to 'fstype' to avoid wireshark genxdrstub.pl error
 -[2/5] use @acl: domain:fs_freeze
 (v2: http://www.redhat.com/archives/libvir-list/2014-November/msg00559.html )

* changes in v1->v2:
 -[all] removed redundant NULL element at the last of returned info array
 -[3/5] make error messages in qemu_agent.c consistent with other commands
 -[4/5] added a test case for 2 items in info->devAliases
 -[5/5] added a pod document for virsh domfsinfo command
 (v1: http://www.redhat.com/archives/libvir-list/2014-October/msg00001.html )

* summary
  This series implements a new virDomainGetFSInfo API, that returns a list of
  mounted filesystems information in the guest, collected via the guest agent.

  The returned info contains mountpoints and disk device alias named in
  libvirt, so we can know which mountpoints should be frozen by
  virDomainFSFreeze to take snapshots of a part of disks.
