[Xen-devel] [PATCH 0 of 11] v3: xl/libxl autoballooning

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,
this patch series adds some new memory management functions to libxl
that are used by xl to autoballoon dom0 down by the amount of memory
needed by the new domain build.
In order to avoid conflicts with other xl instances during the memory
accounting operation I am introducing a global filelock.
I am also introducing a global configuration file for xl to
enable/disable autoballooning.

Changes compares to v2:

- removed max_memkb from libxl_dominfo, added current_memkb instead;

- the changes to instroduce a xenstore transaction in
libxl_set_memory_target have been moved to a separate patch;

- the "enforce" parameter to libxl memory target functions has been
removed;

- get_free_memory_slack has been made static;

- few comments have been added to libxl.h regarding the new memory
related functions;

- code style fixes to avoid lines longer than 80 chars.

Cheers,

Stefano
