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

[libvirt] [PATCH v4 0/9] Implementation of QEMU vhost-scsi
by Eric Farman
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].
Host setup via targetcli (SCSI LUN(s) are already defined to host):
# targetcli
targetcli shell version 2.1.fb35

Changelog:
v4:
- Rebase
- Rebased to current master (21 November)
- s/virDomainPCIAddressEnsureAddr/qemuDomainEnsurePCIAddress/
(per commit abb7a4bd)
- Renaming (apologies if this list is off slightly from the code)
- Per comments in v3.2, some renaming has been performed:
-- virDomainHostdevSubsysHostProtocol => virDomainHostdevSubsysSCSIHostProtocol
-- VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_HOST => VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI_HOST
-- VIR_DOMAIN_HOSTDEV_SUBSYS_HOST_PROTOCOL_TYPE_ => VIR_DOMAIN_HOSTDEV_SUBSYS_SCSI_HOST_PROTOCOL_TYPE_
-- virDomainHostdevSubsysHost => virDomainHostdevSubsysSCSIVHost
-- virDomainHostdevSubsysHost host; => virDomainHostdevSubsysSCSIVHost scsi_host;
-- src/util/virhost.[ch] => src/util/virscsivhost.[ch]
-- virHost... => virSCSIVHost...
-- activeHostHostdevs => activeSCSIVHostHostdevs
-- qemuBuildHostHostdevDevStr => qemuBuildSCSIVHostHostdevDevStr
-- qemuSetupHostHostDeviceCgroup => qemuSetupHostSCSIVHostDeviceCgroup
- Comments
- Checked for a guest address tag that is of type PCI or CCW
(it is optional, and should be calculated automatically)
- Removed the array of "used by" information in hostdev utilities,
since devices will not be shared
- Fixed the existing tests to properly check for an address
- Added a set of CCW tests in addition to the existing PCI ones
- Removed protocol check in PrimeVirtioDeviceAddresses
- Things *NOT* done (later?) from v2 feedback
- Investigation/tie-in with virsh nodedev-list stuff
- Implementation of 'num_queues', 'max_sectors', and 'cmd_per_lun'
(Need to research these in the virtio space, before figuring out
how to apply to vhost-scsi)
- Dropping the "naa." prefix of wwn
- Split the "tests" patch into earlier patches
- Other

[libvirt] [PATCH] qemu: Don't try to find compression program for "raw" memory images
by Peter Krempa
There's nothing to compress if the requested snapshot memory format is
set to 'raw' explicitly. After commit 9e14689ea libvirt would try to
run /sbin/raw to process them emory stream if the qemu.conf option
snapshot_image_format is set.

[libvirt] [PATCH] conf: Make scheduler formatting simpler
by Martin Kletzander
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.
