gluster: command to create a public key file
This executes the command to create a public key file
which will have public keys of all the hosts of source cluster.
This is needed for password-less communication between
slave cluster hosts during geo-replication

vdsm-gluster: Added gluster volume geo-replication start verb
Start the geo-replication session between the hosts.
Start distributed geo-replication on all the nodes that are a part
of the master-volume. Even if any node, that is a part of the
master-volume is down, the command will still be successful.

Change subject: gluster: geo replication status and status detail
......................................................................
gluster: geo replication status and status detail
this has two verbs, status: provides geo-replication status of all running
sessions or all sessions associated with a perticular source volume or
session between a source and remote volume. status detail: provides detailed
status of geo-repliction session between source and remote volume

Change in vdsm[master]: vdsm: Refactoring of retrieving device info from xml
by Vinzenz Feenstra
Vinzenz Feenstra has uploaded a new change for review.
Change subject: vdsm: Refactoring of retrieving device info from xml
......................................................................
vdsm: Refactoring of retrieving device info from xml
Reworked a bit the retrieval of device info from the libvirt domain xml.
Now VDSM won't parse the code in lastXmlDesc every time and the retrieval
of elements from the domain xml has been a bit abstracted.
Additionally the retrieval of an alias has been moved into a separate
function call to make the readability a bit better.

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]: 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.
