[libvirt] [PATCH] [PATCH] vcpupin: add clear feature
by Yi Wang
We can't clear vcpupin settings of XML once we did vcpupin
command, this is not convenient under some condition such
as migration.
This patch introduces clear feature, which can clear vcpuin
setting of XML.

[libvirt] [PATCH] qemuDomainAttachDeviceMknodHelper: Remove symlink before creating it
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1528502
So imagine you have /dev/blah symlink which points to /dev/sda.
You attach /dev/blah as disk to your domain. Libvirt correctly
creates the /dev/blah -> /dev/sda symlink in the qemu namespace.
However, then you detach the disk, change the symlink so that it
points to /dev/sdb and tries to attach the disk again. This time,
however, the attach fails (well, qemu attaches wrong disk)
because the code assumes that symlinks don't change. Well they
do.
This is inspired by test fix written by Eduardo Habkost.

[libvirt] [REBASE PATCH v2 0/8] Implement query-dump command
by John Ferlan
Previous rebase:
https://www.redhat.com/archives/libvir-list/2017-December/msg00124.html
Rebase after pushing first 2 ACK'd patches and for recent capabilities
adjustments. Plus it's been a month...
Original v2:
https://www.redhat.com/archives/libvir-list/2017-November/msg00779.html
Rebase due to additional capabilitiies
v2 Cover:
v1: https://www.redhat.com/archives/libvir-list/2017-November/msg00731.html
Differences from v1 (besides more patches)
Rather than use a timing loop in order to fetch the dump stats and
the presence of the 'query-dump' command, let's use the DUMP_COMPLETED
event and wire that up in order to determine when the dump has been
completed. In the mean time, the previous timing loop is converted into
a qemuDomainGetJobInfoDumpStats to be called if the "right conditions"
exist. Also found/fixed a couple of minor issues from v1 regarding
usage "dumpformat" instead of just "format" from my patch 2 adjustment
and a type for qemuMonitorDumpStatus (was qemuMontiorDumpStatus in v1).
NB: (from v1 cover):
Details in the patches. Essentially though QEMU 2.6 added the ability
to perform the 'dump-guest-memory' via a thread by adding a 'detach'
boolean to the command. In order to watch the progress of the thread
the 'query-dump' command was added. The query-dump will return just
the current status, the total size to be dumped, and the current
progress. So using the migrate stats data in the DomainJobInfo we
can then save our current progress allowing tools such as virsh to
watch that progress. As an added benefit, the dump-guest-memory is
now truly asynchronous.
John Ferlan (8):
qemu: Add support for DUMP_COMPLETED event
qemu: Introduce qemuProcessHandleDumpCompleted
qemu: Introduce qemuMonitor[JSON]QueryDump
qemu: Add new parameter to qemuMonitorDumpToFd
qemu: Introduce qemuDomainGetJobInfoMigrationStats
qemu: Introduce qemuDomainGetJobInfoDumpStats
qemu: Add dump completed event to the capabilities
qemu: Allow showing the dump progress for memory only dump
