Decouple Guest-server/agent from stx-metal
This decouples the build and packaging of guest-server, guest-agent from mtce, by splitting guest component into stx-nfv repo. This leaves existing C++ code, scripts, and resource files untouched, so there is no functional change. Code refactoring is beyond the scope of this update. Makefiles were modified to include devel headers directories /usr/include/mtce-common and /usr/include/mtce-daemon. This ensures there is no contamination with other system headers. The cgts-mtce-common package is renamed and split into: - repo stx-metal: mtce-common, mtce-common-dev - repo stx-metal: mtce - repo stx-nfv: mtce-guest - repo stx-ha: updates package dependencies to mtce-pmon for service-mgmt, sm, and sm-api mtce-common: - contains common and daemon shared source utility code mtce-common-dev: - based on mtce-common, contains devel package required to build mtce-guest and mtce - contains common library archives and headers mtce: - contains components: alarm, fsmon, fsync, heartbeat, hostw, hwmon, maintenance, mtclog, pmon, public, rmon mtce-guest: - contains guest component guest-server, guest-agent Story: 2002829 Task: 22748 Depends-On: https://review.openstack.org/603435 Change-Id: I2ebaf07b94ee5b5abdf8f8db80536351ded22078 Signed-off-by: Jim Gauld <james.gauld@windriver.com>

||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work

(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

||||
|
||||
"Contribution" shall mean any work of authorship, including

2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the

Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of

where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the

This maintenance common guest service provides a means of guest heartbeat
|
||||
orchestration under VIM (system management) control.
|
||||
|
||||
1. Packaging and Initialization:
|
||||
|
||||
The packaging of the heartbeat daemon and heartbeat_init
|
||||
script are modified:
|
||||
|
||||
a. image.inc and filter_out packaging files are modified to exclude the
|
||||
heartbeat daemon from being packaged on the controller.
|
||||
|
||||
b. because the heartbeat daemon is still packaged on the compute
|
||||
heartbeat_init script is modified to prevent the heartbeat
|
||||
daemon from being spawned on the compute host.
|
||||
|
||||
2. Compute Function: Heartbeats the guest and reports failures.
|
||||
|
||||
Package: cgts-mtce-common-guestServer-1.0-r54.0.x86_64.rpm
|
||||
Binary: /usr/local/bin/guestServer
|
||||
Init: /etc/init.d/guestServer
|
||||
Managed: /etc/pmon.d/guestServer.pmon
|
||||
|
||||
3. Controller Function: Guest heartbeat control and event proxy
|
||||
|
||||
Package: cgts-mtce-common-guestAgent-x.x-rxx.x86_64.rpm
|
||||
Binary: /usr/local/bin/guestAgent
|
||||
Init: /usr/lib/ocf/resource.d/platform/guestAgent
|
||||
Managed: by SM
|
||||
|
||||
The heartbeat daemon that did run on the controller is replaced by a new
|
||||
guestAgent daemon performing the following functions
|
||||
|
||||
a. HTTP Command Receiver : to which the VIM sends instance control commands.
|
||||
b. HTTP Event Transmitter: to which the daemon can send instance failure
|
||||
events and state query commands to the VIM.
|
||||
c. State query audit
|
||||
|
||||
Behavioral Executive Summary:
|
||||
|
||||
The guestServer daemon (on the compute) listens for (using inotify) 'uuid'
|
||||
UNIX named heartbeat communication channels that nova:libvirt creates and
|
||||
opens in /var/lib/libvirt/qemu whenever an instance is created. Example:
|
||||
|
||||
/var/lib/libvirt/qemu/cgcs.heartbeat.02e172a9-aeae-4cef-a6bc-7eb9de7825d6.sock
|
||||
|
||||
The guestServer connects (and auto reconnects) to these channels when they are
|
||||
created or modified and disconnects from them when deleted.
|
||||
|
||||
Once connected, the guestServer listens for TCP messages over that UNIX named
|
||||
socket.
|
||||
|
||||
If a guest supports heartbeating then it will run the heartbeat_init script
|
||||
during its initialization process. Once the heartbeat daemon is running it
|
||||
will periodically send init request messages to the libvirt pipe that,
|
||||
on the host side, the guestServer is listening for.
|
||||
|
||||
on receipt of an init message, the guestServer will extract name, timeout
|
||||
and corrective action info from it and then send back an 'init_ack' followed
|
||||
by a continuous heartbeat cycle consisting of sending a 'challenge' request
|
||||
messages and expecting a correct computational responses within a guest specified
|
||||
heartbeat window. Failure to comply will result in a corrective action that was
|
||||
specified in the init message from the guest.
|
||||
|
||||
The VIM is responsible for enabling and disabling heartbeat fault reporting as
|
||||
well as taking the guest specified corrective action in he event of a heartbeat
|
||||
failure.
