[libvirt] [PATCH v2] deprecate -mem-path fallback to anonymous RAM
by Igor Mammedov
Fallback might affect guest or worse whole host performance
or functionality if backing file were used to share guest RAM
with another process.
Patch deprecates fallback so that we could remove it in future
and ensure that QEMU will provide expected behavior and fail if
it can't use user provided backing file.

[libvirt] [PATCH 00/10] qemu: Refactor disk hotplug code for better reuse with blockdev (blockdev-add saga)
by Peter Krempa
Move around few of the helpers which deal with disk addition and
removal and fix a potential bug in the blockdev media change routine.
The refactors will allow simplify a corner case of using blockdev such
as if the disk frontend is unplugged the backends can be unplugged only
after blockjobs terminate.
This will allow simpler handling of the backing chain data in
conjunction with blockjobs.
To test the blockdev part you can use the new XML namespace element for
qemu:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:add capability='blockdev'/>
</qemu:capabilities>
if you have a recent enough qemu.
Peter Krempa (10):
qemu: block: Move and rename qemuHotplugRemoveStorageSourcePrepareData
qemu: hotplug: Handle copy-on-read filter separate from rest of
backing chain
qemu: Introduce new set of helpers for attaching and detaching storage
chains
qemu: command: Use storage chain helpers in commandline generator
qemu: command: Use VIR_AUTO infrastructure in
qemuBuildDiskSourceCommandLine
qemu: command: get rid of 'cleanup' in qemuBuildDiskSourceCommandLine
qemu: hotplug: Use storage chain helpers in
qemuDomainAttachDiskGeneric
qemu: hotplug: Use storage chain helpers in qemuDomainRemoveDiskDevice
qemu: hotplug: qemu: hotplug: Use storage chain helpers in
qemuDomainChangeMediaBlockdev

[libvirt] [PATCH] conf: storage: also sanitize source dir
by Ján Tomko
Commit a7fb2258 added sanitization of storage pool target paths,
however source dir paths were left unsanitized.
A netfs pool with:
<source>
<host name='10.20.30.40'/>
<dir path='/nfs/'/>
</source>
will not be correctly detected as mounted by
virStorageBackendFileSystemIsMounted, because it shows up in the
mount list without the trailing slash.
Sanitize the source dir as well.
