Change in vdsm[master]: Avoid redundant volume produces.
by ewarszaw＠redhat.com
Eduardo has uploaded a new change for review.
Change subject: Avoid redundant volume produces.
......................................................................
Avoid redundant volume produces.
Add sd.getVolumePath() returns the volume path without produce it.
Deprecating hsm.getVolumePath() and hsm.prepareVolume().
When removed, remove API.prepare(), BindingXMLRPC.volumePrepare(),
API.getPath, BindingXMLRPC.volumeGetPath(), etc.

Change in vdsm[master]: vmDevices: add mechanism to persist vmDevice defaults
by mpoledni＠redhat.com
Martin Polednik has uploaded a new change for review.
Change subject: vmDevices: add mechanism to persist vmDevice defaults
......................................................................
vmDevices: add mechanism to persist vmDevice defaults
Multiple vmDevices such as BalloonDevice or watchdogDevice currently
do not persist their defaults in class attributes but rather use them in
XML directly, hiding their existence. This patch aims to change this
behavior by implementing vmDevice._defaults(), which adds the default
attributes to instance directly to enable future persistence of these
classes.

Change in vdsm[master]: Add hostusbdirect hook to vdsm_hooks.
by lyarwood＠redhat.com
Lee Yarwood has uploaded a new change for review.
Change subject: Add hostusbdirect hook to vdsm_hooks.
......................................................................
Add hostusbdirect hook to vdsm_hooks.
This is a slight variation of the hostusb hook. This version uses the bus and
device IDs to attach host USB device to the guest using the following libvirt XML :
<hostdev mode='subsystem' type='usb' managed='yes'>
<source>
<address bus='001' device='003'/>
</source>
</hostdev>
In the future this could be merged with the hostusb hook.

Change in vdsm[master]: [WIP] Implement a process to do dangerous IO in C
by smizrahi＠redhat.com
Saggi Mizrahi has uploaded a new change for review.
Change subject: [WIP] Implement a process to do dangerous IO in C
......................................................................
[WIP] Implement a process to do dangerous IO in C
This replaces the process pool with a process that can serve multiple
requests written in C.
This implementation is much more scalable and lightweight. Should solve
bugs related to running out of helpers, logging getting suck, python
forking deadlocking, running out of memory and other things as well.
The communication between VDSM and the IOProcess is done with json
objects.
The IOProcess starts with 3 thread:
1. requestReader - reads requests from the pipe, builds a DOM
representation of it and queues it up for handling
2. responseWriter - gets response DOMs from the queue converts them to a
JSON string and send it over the pipe
3. requestHandler - pops requests from the queue and provisions threads
for handling them. Currently we I just allocate a new thread per
request. If there is ever a need to have a thread pool this is where
the load balancing is going to sit.
Each request gets the are as a JsonNode and returns a response that is a
JsonNode as well. Most exported functions are pretty trivial and are a
good example on how to write new ones.
Unlink the ProcessPoolHelper, high level commands sit of the OopWrapper
and are run from the client side instead of being implemented in C on
the IOProcess side.
