Change in vdsm[master]: vm: Cleaner vm stats thread initialization
by Nir Soffer
Nir Soffer has uploaded a new change for review.
Change subject: vm: Cleaner vm stats thread initialization
......................................................................
vm: Cleaner vm stats thread initialization
The vm stats thread was initialized too late, leading to unneeded checks
and unclear try except blocks when trying to stop the thread.
This patch changes AdvancedStatsThread so it keeps a thread instance
instead of inheriting from Thread, and initialize it in Vm.__init__, so
it is always available when we access it.

In order to support an entity-based polling methodology (ie. in the new

running operation. Extend the getVolumeInfo API to report whether the
lease is free or held.

Change in vdsm[master]: freeze: Freeze guest even when creating memory snapshot
by Nir Soffer
Nir Soffer has uploaded a new change for review.
Change subject: freeze: Freeze guest even when creating memory snapshot
......................................................................
freeze: Freeze guest even when creating memory snapshot
We used to skip freezing the guest if creating memory snapshot. This was
probably done because qemu is pausing the vm for creating memory
snapshot.
However, this is not consistent with snapshots of external disks such as
network disks, where we always freeze the vm before taking the snapshot.
Also, it is probably safer to freeze even when creating memory snapshot,
giving applications on the guest chance to pause in consistent state.
This patch removes the check for memory snapshot, and freeze the guest
unless it is already frozen.

Change subject: log: Use INFO log level as default
......................................................................
log: Use INFO log level as default
The current logs are much too verbose which cause trouble for users, and
make us look unprofessional. Mature project should not use debug log by
default.
To debug issues that are not clear enough using INFO logs, the relevant
logger level can be modified on a user machine as needed.
