[libvirt] [PATCHv2 00/16] bypass-cache in save/restore

[Eric Blake]

Incorporating review comments from v1:
https://www.redhat.com/archives/libvir-list/2011-July/msg00842.html

Still to be written: new API for managing save state images in isolation:
https://www.redhat.com/archives/libvir-list/2011-July/msg00855.html
virConnectDomainSaveGetXMLDesc
virConnectDomainSaveModify

as well as virsh commands to wrap them:
virsh managedsave-dumpxml file
virsh managedsave-define file xml
virsh managedsave-edit file

Eric Blake (16):
  command: move all docs into .c file
  command: avoid leaking fds across fork
  build: rename files.h to virfile.h
  qemu: fix error message with migrate2 xml
  save: document new public API
  save: wire up remote protocol
  save: wire up trivial save/restore flags implementations
  save: add --bypass-cache flag to virsh save/restore operations
  save: support --xml to virsh save/restore
  save: let iohelper handle inherited fd
  save: let iohelper work on O_DIRECT fds
  save: add virFileDirectFd wrapper type
  save: support BYPASS_CACHE during qemu save/restore
  save: support bypass-cache flag in qemu.conf
  save: support bypass-cache flag in libvirt-guests init script
  save: support qemu modifying xml on domain save/restore
