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

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(a)knightpoint.com&gt; 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
