I noticed a few small bugs while fixing the domain maximum
memory bugs :-). See patches for details.

by Joao Martins
If no graphics element is in XML xenFormatXLSpice will access
graphics without checking it has one in the first place, leading to a

[libvirt] [PATCH] qemu_security: Introduce ImageLabel APIs
by Michal Privoznik
Just like we need wrappers over other virSecurityManager APIs, we
need one for virSecurityManagerSetImageLabel and
virSecurityManagerRestoreImageLabel. Otherwise we might end up
relabelling device in wrong namespace.

[libvirt] [resend v2 0/7] Support cache tune in libvirt
by Eli Qiao
This series patches are for supportting CAT featues, which also
called cache tune in libvirt.
First to expose cache information which could be tuned in capabilites XML.
Then add new domain xml element support to add cacahe bank which will apply
on this libvirt domain.
This series patches add a util file `resctrl.c/h`, an interface to talk with
linux kernel's sys fs.
There are still some TODOs such as expose new public interface to get free
cache information.
Some discussion about this feature support can be found from:
https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html
Eli Qiao (7):
Resctrl: Add some utils functions
Resctrl: expose cache information to capabilities
Resctrl: Add new xml element to support cache tune
Resctrl: Add private interface to set cachebanks
Qemu: Set cache banks
Resctrl: enable l3code/l3data
Resctrl: Make sure l3data/l3code are pairs

[libvirt] [PATCH] conf: fix use-after-free when sending event message
by Wang King
If there is a process with a client which registers event callbacks,
and it calls libvirt's API which uses the same virConnectPtr in that
callback function. When this process exit abnormally lead to client
disconnect, there is a possibility that the main thread is refer to
virServerClient just after the virServerClient been freed by job
thread of libvirtd.
Following is the backtrace:

[libvirt] [Block Replication] Question about supporting COLO in libvirt
by Hailiang Zhang
Hi,
I'm trying to implement supporting COLO in libvirt,
But i found an annoying problem that libvirt does not
support the command line option argument syntax we used
for block replication in QEMU.
That is libvirt does not support the bellow syntax for block:
-drive driver=qcow2,file.filename=test:a.qcow2
-drive file=test.qcow2,\
backing.file.filename=/dev/fdset/1
It seems to be a new syntax that libvirt does not support
thought it has been exist in QEMU for a time.
I found some introductions from
http://www.linux-kvm.org/images/3/34/Kvm-forum-2013-block-dev-configurati...
The command line we use for COLO is just like the above syntax,
For example, for the shared disk in COLO, it is:
-drive if=none,driver=qcow2,file.filename=/mnt/ramfs/hidden_disk.img,id=hidden_disk0,\
backing.driver=raw,backing.file.filename=1.raw \
-drive if=virtio,id=active-disk0,driver=replication,mode=secondary,\
file.driver=qcow2,top-id=active-disk0,\
file.file.filename=/mnt/ramfs/active_disk.img,\
file.backing=hidden_disk0,shared-disk=on
For the none-shared disk in COLO, it is quite same with the shared-disk:
-drive if=none,driver=raw,file.filename=1.raw,id=colo1 \
-drive if=xxx,id=topxxx,driver=replication,mode=secondary,top-id=topxxx\
file.file.filename=active_disk.qcow2,\
file.driver=qcow2,\
file.backing.file.filename=hidden_disk.qcow2,\
file.backing.driver=qcow2,\
file.backing.backing=colo1
So there seems to be two ways to solve this problem.
One is to support this new option argument syntax in libvirt,
but I'm not sure if it is difficult or not to implement it,
and i don't know where to start either.
Another way is to convert these command line options in QEMU totally,
I mean hidden the descriptions of 'active_disk' and 'hidden_disk' disks.
Create/add them dynamicly by qmp commands while users want to make VM goes
into COLO state. That's just like to support live image clone in QEMU.
Any ideas ?
Thanks,
Hailiang

[libvirt] [PATCH] libxl: fix disk detach when <driver> not specified
by Jim Fehlig
When a user does not explicitly set a <driver> in the disk config,
libvirt defers selection of a default to libxl. This approach works
fine when starting a domain with such configuration or attaching a
disk to a running domain. But when detaching such a disk, libxl
will fail with "unrecognized disk backend type: 0". libxl makes no
attempt to recalculate a default backend (driver) on detach and
simply fails when uninitialized.
This patch updates the libvirt disk config with the backend selected
by libxl when starting a domain or attaching a disk to a running
domain. Another benefit of this approach is that the live XML is
also updated with the backend driver selected by libxl.

[libvirt] [PATCH v3] qemu: Forbid <memoryBacking><locked> without <memtune><hard_limit>
by Andrea Bolognani
In order for memory locking to work, the hard limit on memory
locking (and usage) has to be set appropriately by the user.
The documentation mentions the requirement already: with this
patch, it's going to be enforced by runtime checks as well,
by forbidding a non-compliant guest from being defined as well
as edited and started.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1316774
---
Changes from [v2]
* Address review feedback:
- move the check from BuildCommandLine to Validate.
Changes from [v1]
* Address review feeback:
- check in BuildCommandLine rather than in PostParse,
so that non-compliant guests will merely fail to
start rather than disappear completely.
