[libvirt] [PATCH v6 0/5] migration: add multithread compression
by Nikolay Shirokovskiy
Add means to turn multithread compression on during migration.
Add means to pass compression parameters in migration command.
WARNING!
This should be pushed only after
https://www.redhat.com/archives/libvir-list/2016-March/msg01506.html
or virsh domain will break.
Changes from v5
===============
Originally i just wanted to send a rebase as i discovered that automatic
rebase goes wrong for the patch 1 but later found a couple of bugs
in the patch itself. Here they are:
1. fix qemuDomainMigratePrepare2 and qemuDomainMigratePerform3
passing NULL for compression.
Changes from v4
===============
1. Clean up documentation and comments.
2. Stop keeping compression options in flags internally. Move
flags data into generic compression structure.
3. Use existing libvirt enum infrastructure to deal with
compression methods. This makes parse and dump function less
painful.
4. Use booleans for 'set' flags instead of bitsets.
5. Othes minor changes on Jiri comments.

[libvirt] [PATCH] virsh: support up to 64 migration options for command
by Nikolay Shirokovskiy
Upcoming compression options for migration command patch
series hits current limit of 32 possible options for a command.
Lets take one step further and support 64 possible options.
And all it takes is moving from 32 bit integers to 64 bit ones.
The only less then trivial change i found is moving from
'ffs' to 'ffsl'.

[libvirt] [PATCH] virsh: use the same connection URI for reconnect
by Roman Bogorodskiy
When for some reason virsh looses connection and then tries to
reconnection, it uses the default URI instead of the one that was used
for the previous connection it got disconnected from.
In order to make it reconnect using the same URI, copy URI of the
current (disconnected) connection to vshControl 'connname' attribute.

[libvirt] [PATCH REBASE 0/4] vz: use disk bus and target name as disk id
by Nikolay Shirokovskiy
This series is a preparation to implement device update functionality.
In case of disk updates disk bus and disk target name pair is considered
disk id. We already have places in vz driver code where we use disk source
as id. These places are either not critical (see boot patch) or
correct (see detach patch) so we need not to fix them immediately to use more
rubust id. But as this id will be introduced anyway for disk updates
let's move to new id in existing code. This way we have single
id for disks.
Nikolay Shirokovskiy (4):
vz: introduce vzsdk disk id function
vz: fix detach disk to use new disk id
vz: fix boot check to use new disk id
vz: cleanup: remove trivial function

[libvirt] [PATCH] storage: mpath: Don't error on target_type=NULL
by Cole Robinson
We use device-mapper to enumerate all dm devices, and filter out
the list of multipath devices by checking the target_type string
name. The code however cancels all scanning if we encounter
target_type=NULL
I don't know how to reproduce that situation, but a user was hitting
it in their setup, and inspecting the lvm2/device-mapper code shows
many places where !target_type is explicitly ignored and processing
continues on to the next device. So I think we should do the same

[libvirt] [PATCH] fix build by correcting functions order and src/Makefile.am
by Maxim Nestratov
commit 30c61901 added new functions to libvirt_private.syms
not alpabetically sorted and erroneously added vz sources to
STATEFUL_DRIVER_SOURCE_FILES, which triggered check-aclrules
running while vz driver isn't ready for it yet.
Pushing under build-breaker rule.
