[libvirt] [PATCH] qemu: fix wrong remove guest cfg if migrate fail
by Luyao Huang
If we get fail in qemuMigrationPrepareAny, we forget
check if the vm is persistent then always call
qemuDomainRemoveInactive to clean the inactive settings.
Add a check to avoid this. This issue was introduce in
commit 540c339.

[libvirt] [PATCH] virt-xml-validate: Allow input to be read from stdin
by Johannes Holmberg
---
Hello,
I often find myself wanting to validate a domain xml without having
to save it to a file, so I've updated virt-xml-validate to support
the standard practice of reading from stdin when "-" is given as the
input file.
Of course, the validation is multipass so there still needs to be a
temporary file but I think it makes sense to hide this complexity in
virt-xml-validate and not force it onto the user.

[libvirt] [PATCH] qemu:conf: introduce a function to delete vcpu sched
by Luyao Huang
https://bugzilla.redhat.com/show_bug.cgi?id=1235180
We have API allow vpu to be deleted, but an vcpu may be
included in some domain vcpu sched, so add a new API to
allow removing an iothread from some entry.
Split the virDomainIOThreadSchedDelId to reuse some code.

[libvirt] [PATCH] test: Refactor vcpu pinning and vcpu info retrieval
by Peter Krempa
Drop internal data structures and use the proper fields in virDomainDef.
This allows to greatly simplify the code and allows to remove the
private data structure that was holding just redundant data.
This patch also fixes the bogous output where we'd report that a fresh
VM without vCPU pinning would not run on all vcpus.

[libvirt] [sandbox PATCH 00/10] Patches for libvirt-sandbox
by Eren Yagdiran
Hello,
These patches provide disk support for libvirt-sandbox.
Implemented '--disk' parameter will be useful when integrating Docker image support for libvirt-sandbox.
--Main diffs compared to previous patches.
Since many hypervisors, including kvm, will not even honour requested
names for disk devices we link each device under /dev/disk/by-tag
e.g /dev/disk/by-tag/foobar -> /dev/sda
We populate disks.cfg with tag to device mapping when we build the sandbox.
After that, in each init-process {Common,Qemu}, we basically read the configuration
and populate the right symlinks under /dev/disk/by-tag
The common functions for modifying directories are moved under Init-util. {Common,Qemu} inits are using them.
Cédric Bosdonnat (2):
Add gvir_sandbox_config_has_disks function
qemu: use devtmpfs rather than tmpfs to auto-populate /dev
Eren Yagdiran (8):
Add an utility function for guessing filetype from file extension
Add configuration object for disk support
Add disk parameter to virt-sandbox
Add disk support to the container builder
Add disk support to machine builder
Init-util : Common directory functions for init-common and init-qemu
Common-init: Building symlink from disks.cfg
Common-builder: /dev/disk/by-tag/thetag to /dev/vdN
