Change in vdsm[master]: sd: fix volume path returned by linkBCImage
by Federico Simoncelli
Federico Simoncelli has uploaded a new change for review.
Change subject: sd: fix volume path returned by linkBCImage
......................................................................
sd: fix volume path returned by linkBCImage
In a previous commit (c072945 One shot prepare) we involuntarily
changed the path used for virtual machine images from:
/rhev/data-center/<spUUID>/<sdUUID>/images/<imgUUID>/<volUUID>
to:
/rhev/data-center/mnt/blockSD/<sdUUID>/images/<imgUUID>/<volUUID>
This patch reverts to the previous path in order to minimize the
differences between different versions of vdsm that could lead to
live migration issues, e.g.
libvirtError: invalid argument: invalid path ... not assigned to
domain

Change in vdsm[master]: vm: spice support to agent file transfer disable
by fromani＠redhat.com
Francesco Romani has uploaded a new change for review.
Change subject: vm: spice support to agent file transfer disable
......................................................................
vm: spice support to agent file transfer disable
Spice has agent based file transfer support.
This option can be disabled in QEMU, and libvirt has support
to pass this flag to the underlying QEMU.
This patch expose this capability in VDSM, in the VM definition,
implementing the VDSM part of bz983019.
The new parameter is optional and enabled by default for backward
compatibility.
No XML changes are produced at all unless the new parameter is
specified.

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.

Change in vdsm[master]: Avoid calling restorecon on a nonexistent dir.
by mtayer＠redhat.com
mooli tayer has uploaded a new change for review.
Change subject: Avoid calling restorecon on a nonexistent dir.
......................................................................
Avoid calling restorecon on a nonexistent dir.
/var/log/core is only created when vdsm service goes up.
If vdsm never ran on the machine we might get:
restorecon: lstat(/var/log/core) failed: No such file or directory
