[PATCH RFC 0/3] Add checkpoint/restore support to LXC using CRIU
by Julio Faracco
This patch series implements a way to do checkpoint/restore to LXC driver using
CRIU operations. This respects the other methods to save and restore processes
states: using a file with a header with some metadata. The only difference here
is basically the way LXC drivers join the files produced by CRIU. CRIU generates
a lots of 'img' files and it is compresses using TAR to fit into the libvirt
state file.
Julio Faracco (3):
meson: Add support to CRIU binary into meson
lxc: Including CRIU functions and functions to support C/R.
lxc: Adding support to LXC driver to restore a container

[PATCH] XML <source bridge='VMnet0'/> update in <interface type='bridge'/>
by Kristina Hanicova
Previously, we accepted empty bridge name, because some old versions of
VMWare Workstation did not put it into the config. But this doesn't make
much sense - to have an interface type bridge with no name. We
circumvented this problem by generating an empty name but that is
equally wrong.
Therefore, fill in missing bridge names (according to the documentation
[1] the default bridge name is VMnet0) and error out if bridge name is
missing.
This partially reverts f246cdb5aca13ac9409b2ad43087e3078615ffcb

[PATCH 0/6] qemu: Allow control of deprecation behaviour
by Peter Krempa
For debugging purposes it's very useful to disable all deprecated
commands and fields in qemu. This series implements a qemu.conf knob and
a qemu namespace element to control this.
The implementation tries to be very conservative to allow downgrades of
qemu and such without breaking the startup of the VM.
The intention is that developers and CI deployments use the 'crash'
option to catch any unexpected qemu disappearance.
Note that this applies on top of my series for -object QAPIfication.
Based on Markus' -compat series which was now merged to upstream qemu.
Peter Krempa (6):
docs/drvqemu: Convert to RST
qemu: capabilities: Introduce QEMU_CAPS_COMPAT_DEPRECATED
qemu: conf: Add 'deprecation_behavior' setting to qemu.conf
qemuxml2xmltest: Enable 'qemu-ns' case

[libvirt PATCH 0/2] qemu: wire up support for rotation rate for disks
by Daniel P. Berrangé
By default QEMU doesn't report any rotation information to guests, so
guests assume rotational media. This lets the user specify an explicit
speed in RPM, or 1 for SSD. This may allow the user to achieve better
performance for their virtual disks. Note, however, this doesn't mean
that the guest should be given the same setting as the host storage.
It is possible that better performance may be achieved with contrary
settings from the host. Testing is required to determine this on a
case by case basis.

[Libvirt] Attach qemu commands to an running xml domain
by Waleed Musa
Hi all,
I see in libvirt you are supporting attach/detach devices to existing xml domain using attachDeviceFlags and detachDeviceFlags APIs.
Now we are adding some qemu command to the xml domain related to some interfaces using alias names before starting the VM, but we will face an issue with hot plug such devices, so I have two question here:
1. Is it applicable to set the alias names for interfaces because I saw it's ignored when I add it to xml domain before starting the VM?
2. Is there a way or API to attach qemu commands to running domain as you are doing in attaching the device using attachDeviceFlags?
Example of my xml
<domain type='kvm' id='5' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<devices>
