Change in vdsm[master]: migration: make stop() update internal status
by fromani＠redhat.com
Francesco Romani has uploaded a new change for review.
Change subject: migration: make stop() update internal status
......................................................................
migration: make stop() update internal status
The SourceThread.stop() operation should update
the internal status accordingly in case of success.
Previously, it was the caller that updated the status (!)
adding unneeded coupling.

Change in vdsm[master]: sampling: introduce expensive checks
by fromani＠redhat.com

Change subject: sampling: introduce expensive checks
......................................................................
sampling: introduce expensive checks
To improve troubleshooting, introduce more
expensive sanity checks, with a default-off
tunable to enable them.
These sanity checks will make no attempt to recover,
will only add logs to report possible issues.

Francesco Romani has uploaded a new change for review.
Change subject: sampling: simplify flows
......................................................................
sampling: simplify flows
Executor already has a fallback net for uncaught exceptions.
Failures in SampleVMs.__call__ are expected to be sporadic,
and in these cases we actually want to be as much noisy as we
can.
This patch removes redundant code in SampleVMs.__call__,
to make the flow less convoluted.

Change in vdsm[master]: hsm: prepareForShutdown - operations order
by laravot＠redhat.com
Liron Aravot has uploaded a new change for review.
Change subject: hsm: prepareForShutdown - operations order
......................................................................
hsm: prepareForShutdown - operations order
Currently cleanupMasterMount() is executed before
taskMgr.prepareForShutdown() and before the domain monitor is stopped,
that causes to errors during the tasks abortion (becasue of failure to
access the path) and to erros when stopping the domain monitoring
thread on that domain.
The solution introduced in that patch is to change the order of the
operations - so that the cleanupMasterMount() will be executed only
after the other operations are executed.

Change in vdsm[master]: janitorial: vm: remove _reportError
by fromani＠redhat.com
Francesco Romani has uploaded a new change for review.
Change subject: janitorial: vm: remove _reportError
......................................................................
janitorial: vm: remove _reportError
Vm._reportError was an early attempt to build what
we have now with response.error().
With the new code in place there is no more reason
to use it, so this patch removes it.

Change in vdsm[master]: virt: add test to allow custom XML parsing test
by Martin Polednik
Martin Polednik has uploaded a new change for review.
Change subject: virt: add test to allow custom XML parsing test
......................................................................
virt: add test to allow custom XML parsing test
Tests should run against explicit device specification, but it may be
useful to have a means of simply testing that parse of given XML
succeeds. This patch implements such functionality, allowing user to
supply XML in tests/devices/data and modify
tests/parsing/custom_vm_tests.py to see if the parsing conforms general
device specification.
