Allow saving VM state to pipe

[libvirt] [PATCH v3 0/2] Allow saving VM state to pipe

Posted by Chen Hanxiao 7 years, 1 month ago

This series introduce flag VIR_DOMAIN_SAVE_DIRECT
to enable command 'save' to write to PIPE.
This will write QEMU_SAVE_MAGIC directly.

Base upon patches from Roy Keene <rkeene@knightpoint.com>
with some fixes.

Change from original patch:
1) Check whether the specified path is a PIPE.
2) Rebase on upstream.
3) Add doc for virsh command

v3:
  add doc/news.xml
  rebase on upstream

v2-resend:
  rebase on upstream

v2:
  rename VIR_DOMAIN_SAVE_PIPE to VIR_DOMAIN_SAVE_DIRECT
  remove S_ISFIFO check
