[libvirt] [PATCH 0/2] Allow saving QEMU libvirt state to a pipe
by Chen Hanxiao 08 Dec '16

08 Dec '16

This series introduce flag VIR_DOMAIN_SAVE_PIPE to enable command 'save' to write to PIPE. Base upon patches from Roy Keene <rkeene(a)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 Chen Hanxiao (2): qemu: Allow saving QEMU libvirt state to a pipe virsh: introduce flage --pipe for save command include/libvirt/libvirt-domain.h | 1 + src/qemu/qemu_driver.c | 71 ++++++++++++++++++++++++++++++---------- tools/virsh-domain.c | 6 ++++ tools/virsh.pod | 6 +++- 4 files changed, 65 insertions(+), 19 deletions(-) -- 2.7.4

[libvirt] [PATCH v4 0/9] Implementation of QEMU vhost-scsi
by Eric Farman 08 Dec '16

08 Dec '16

This patch series provides a libvirt implementation of the vhost-scsi interface in QEMU. As near as I can see, this was discussed upstream in July 2014[1], and ended in a desire to replace a vhost-scsi controller in favor of a hostdev element instead[2].

[libvirt] [PATCH] conf: Make scheduler formatting simpler
by Martin Kletzander 08 Dec '16

08 Dec '16

Since the great rework of how we store vcpu- and iothread-related data, we have overly complex part of code that is trying to format the scheduler tuning data in as less lines as possible by grouping settings for multiple threads. That was designed as an input syntax sugar for users, but we don't need to also use that when formatting the XML. Switching to simple enumeration makes the code nicer, shorter and more welcoming to future changes.
