[libvirt] [PATCH] libxl: resume lock process after failed migration
by Jim Fehlig
During migration, the lock process is paused in the perform phase
but not resumed if there is a subsequent failure, leaving the locked
resource unprotected.
The perform phase itself can fail, in which case the lock process
should be resumed before returning from perform. The finish phase
could also fail on the destination host, in which case the migration
is canceled in the confirm phase and the VM is resumed. The lock
process needs to be resumed there as well.

[libvirt] [PATCH] vbox: fix SEGV during dumpxml of a serial port
by Laine Stump
commit 77a12987a48 changed the "virDomainChrSourceDef source" inside
virDomainChrDef to "virDomainChrSourceDefPtr source", and started
allocating source inside virDomainChrDefNew(), but vboxDumpSerial()
was allocating a virDomainChrDef with a simple VIR_ALLOC(), so source
was never initialized, leading to a SEGV any time a serial port was
present. The same problem was created in vboxDumpParallel().
This patch changes vboxDumpSerial() and vboxDumpParallel() to use
virDomainChrDefNew() instead of VIR_ALLOC(), and makes a cursory
attempt to "recover" from OOM afterwards (much of the vbox code was
written to assume success, e.g. by having functions return void. Since
I have no way to test a more sweeping change to this code, I chose to
just short-circuit the rest of the function if virDomainChrDefNew()
fails - this is at least one step better than the previous code, which
would otherwise end up trying to dereference a NULL def->serials[i]
and crash libvirtd.
This resolves: https://bugzilla.redhat.com/1536649

[libvirt] [PATCH 00/14] Misc build refactoring / isolation work
by Daniel P. Berrangé
This was triggered by the recent Fedora change to add '-z defs' to RPM
builds by default which breaks libvirt. Various make rule changes can
fix much of the problem, but it also requires source refactoring to get
rid of places where virt drivers directly call into the storage/network
drivers. Co-incidentally this work will also be useful in allowing us to
separate out drivers to distinct daemons.
Daniel P. Berrangé (14):
storage: extract storage file backend from main storage driver backend
storage: move storage file backend framework into util directory
rpc: don't link in second copy of RPC code to libvirtd & lockd plugin
conf: introduce callback registration for domain net device allocation
conf: expand network device callbacks to cover bandwidth updates
qemu: replace networkGetNetworkAddress with public API calls
conf: expand network device callbacks to cover resolving NIC type
network: remove conditional declarations
conf: move virStorageTranslateDiskSourcePool into domain conf
storage: export virStoragePoolLookupByTargetPath as a public API
build: explicitly link all modules with libvirt.so
build: provide a AM_FLAGS_MOD for loadable modules
build: passing the "-z defs" linker flag to prevent undefined symbols
build: link libvirt_lxc against libvirt.so

[libvirt] [PATCH 00/10] Cache Allocation Technology support, this time for real (??)
by Martin Kletzander
So again all the reviews are incorporated. I managed to get my hands on
a machine with CAT support, so I also found out some things that needed
tweaking.
@Eli: I would still appreciate you helping with some testing as I wasn't
able to find a machine with multiple caches (sockets) and I
couldn't test that properly (mainly the fact that full mask needs
to be specified for caches for which we don't want any allocation
to happen).
Martin Kletzander (10):
Rename virResctrlInfo to virResctrlInfoPerCache
util: Add virResctrlInfo
conf: Use virResctrlInfo in capabilities
util: Remove now-unneeded resctrl functions
resctrl: Add functions to work with resctrl allocations
conf: Add support for cputune/cachetune
tests: Add virresctrltest
qemu: Add support for resctrl
docs: Add CAT (resctrl) support into news.xml
tests: Clean up and modify some vircaps2xmldata

[libvirt] [PATCH v3 0/3] nodedev: update caps before quering nodedev infos
by Wu Zongyong
Some capabilities of node devices rely on what driver they bound to,
and therefore, these capabilities may change when the driver change.
In current implemention, it is not consistent between real status and
the status we get by invoking nodedev interfaces.
So, this series of patches try to manually update devices' capabilities
each time before nodedev driver interfaces invoked.
Wu Zongyong (3):
v2->v3:
1. split a single patch to three part
2. fix memory leak and lock problems
3. update caps before invoking nodedev driver interfaces (refer to patch 3/3)
nodedev: add macro guard to node_device_udev header file
nodedev: update mdev_types caps before dumpxml
nodedev: update caps before invoking nodedev driver interfaces
