[libvirt] [PATCH v2 0/5] parallels: manage container's filesystems
by Dmitry Guryanov
This patch series adds ability to manage container's
filesystems: you can add or remove fs from existing
container or create new one, based on existing
disk image.
Dmitry Guryanov (5):
add ploop fs driver type
parallels: dump info about container filesystems
parallels: commit with PVCF_DETACH_HDD_BUNDLE flag
parallels: allow to add filesystems to container
parallels: create container from existing image

[libvirt] [PATCH] network: Resolve Coverity FORWARD_NULL
by John Ferlan
Commit id 'ca481a6f' added virNetworkRouteDefFree which may be called
in an error path from lxcAddNetworkRouteDefinition with 'route = NULL'.
So just add the (!def) at the top to resolve.

[libvirt] [PATCH v3] virsh: add support for domain XML validation
by Daniel P. Berrange
The 'virsh edit' command gets XML validation enabled by default,
with a --skip-validate option to disable it. The 'virsh define'
and 'virsh create' commands get a --validate option to enable
it, to avoid regressions for existing scripts.
The quality of error reporting from libxml2 varies depending
on the type of XML error made. Sometimes it is quite clear
and useful, other times it is obscure & inaccurate. At least
the user will see an error now, rather than having their
XML modification silently disappear.

[libvirt] [PATCH] qemu: fix fail to start vm with one cell use memdev and another not
by Luyao Huang
https://bugzilla.redhat.com/show_bug.cgi?id=1182467
We changed our build numa qemu cmd line way in f309db,
But qemu cannot accept one cell use memdev and another not,
so this cause a issue when we start a vm with one cell
have hugpage or nodemask settings and others not.
After this patch we will use memdev for all cells if there
is at least one cell need this.

[libvirt] [PATCH] Allow shrinking of file based volumes
by Daniel P. Berrange
While the main storage driver code allows the flag
VIR_STORAGE_VOL_RESIZE_SHRINK to be set, none of the backend
drivers are supporting it. At the very least this can work
for plain file based volumes since we just ftruncate() them
to the new size. It does not work with qcow2 volumes, but we
can arguably delegate to qemu-img for error reporting for that
instead of second guessing this for ourselves:
$ virsh vol-resize --shrink /home/berrange/VirtualMachines/demo.qcow2 2G
error: Failed to change size of volume 'demo.qcow2' to 2G
error: internal error: Child process (/usr/bin/qemu-img resize /home/berrange/VirtualMachines/demo.qcow2 2147483648) unexpected exit status 1: qemu-img: qcow2 doesn't support shrinking images yet

[libvirt] [PATCH v2 0/2] check IOMMU group devices usage when preparing device for vfio passthrough

====================================================================
If a device in the same iommu group is in use by a different vm, the guest boot
fails with the below error during vfio passthrough.
bash-4.2$ virsh start demo
error: Failed to start domain demo
error: internal error: process exited while connecting to monitor:

Solution:
=====================================================================
The patch iterates through the iommu group devices and errors out cleanly
mentioning the device and the guest which is using the device.
With Patch

[libvirt] [PATCH 0/3] Add stateDir for storage driver and use for disk backend
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1138516
Using the network (and domain) for reference, add a 'stateDir' for the
Storage Driver in order to save off pool and/or volume specific information
into a live running area.
This is useful for the disk backend where volume creation can define a
specific name and target format type to use; however, that information
cannot be encoded into the 'parted' data used to create the partition(s)
on the disk. Thus the data is lost for refresh and restart/reload.
The following patches will add the stateDir, then the infrastructure for
storage volume xml to be saved off, and finally saving/using that data
for the refresh, restart/reload path for the disk backend driver.
John Ferlan (3):
storage: Create a stateDir
storage: Introduce virStorageVol{Save|Delete}Status
storage: Adjustments to disk backend to use stateDir
