[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] xenballoond: remove as it is now obsolete + unsupported code
Dan, the author, states:
> this code is five years old, is distro dependent, and is now
> completely unsupported.

Dan says:
I'd like to get Konrad's opinion first.
This kind of question seems to come up about once a year and its
existence in the tree serves as a good example of what can be
done with ballooning in legacy/unmodified Linux guests (e.g.
shows how to write to the balloon driver via sysfs).
So I'll defer to your decision if Konrad agrees.

-# xenballoond - In-guest engine for Xen memory ballooning
-# Original version: 080630

-#
-# Two self-ballooning "policies" are implemented:
-# - Selfballooning: Adjust memory periodically, with no (or little) input
-# from domain0. Target memory is determined solely by the

-# the rate at which the target is achieved.
-# - Directed ballooning: Adjust memory solely as directed by domain0
-#
-# Under some circumstances, "output" may also be generated; the contents
-# of /proc/meminfo and /proc/vmstat may be periodically placed on xenbus.
-#
-# If xenbus is running and the /usr/bin/xenstore-* tools are installed,
-# "xenbus is enabled".
-#
-# Parameters are documented in <SYSCONFIG>/xenballoon.conf. Although
-# some are not used with directed ballooning, all must be set properly.
-# If xenbus is enabled, some of these parameters may be overridden by values

-INTRODUCTION
-
-Xenballoond runs in guest domains and both implements selfballooning and
-provides metrics to dom0 for (future) directed ballooning. Both capabilities
-provide a foundation for basic "memory overcommit" functionality.
-
-With selfballooning enabled, xenballoond uses the Committed_AS value found
-in /proc/meminfo as a first approximation of how much memory is required
-by the guest and feeds this statistic back to the balloon driver to inflate
-or deflate the balloon as required to achieve the target guest memory size.
-Hysteresis parameters may be adjusted to rate-limit balloon inflation
-and deflation.
-
-If configured, certain selfballooning parameters -- including notably
-enabling/disabling of self-ballooning -- can be controlled from domain0.
-(These are fully documented in xenballoon.conf.)
-
-If configured, the following guest statistics are sent back to domain0:
-- /proc/meminfo
-- /proc/vmstat
-- /proc/uptime
-In a future release, some of these values will be used by a policy module
-in domain0 to control guest balloon size and provide memory balancing
-across all guests on a given system.
-
-Note that no page sharing (content-based or otherwise) is implemented
-and no VMM-based swapping is necessary.
-
-For more information, see:
-http://www.xen.org/files/xensummitboston08/MemoryOvercommit-XenSummit2008.pdf
-http://wiki.xensource.com/xenwiki/Open_Topics_For_Discussion?action=AttachFile&do=get&target=Memory+Overcommit.pdf
-
-INSTALLATION AND DEPLOYMENT
-
-In this preliminary release:
-- directed ballooning is not implemented, though a monitor is provided
-- only Redhat-based guests are supported
-
-Guest prerequisites to use xenballoond:
-- each guest must be configured with adequate[1] swap space
-- each guest must have the balloon driver installed (/proc/xen/balloon exists)
-- if directed ballooning (or monitoring) is desired, xenstore tools must be
- installed in each guest in /usr/bin [2]
-
-[1] for best results, for a guest that is configured with maxmem=N and
- requires Z MB of swap space without xenballoond, available swap should
- be increased to N+Z MB when xenballoond is running
-[2] specifically xenstore-read, xenstore-exists, and xenstore-write must
- be installed. Binaries can be obtained, for example, by building
- xen-vvv.gz/tools in a guest-binary-compatible development tree
-
-Instructions to install/deploy xenballoond:
- (see docs/misc/distro_mapping.txt for SYSCONFIG and INITD_DIR definitions)
-- in each guest:
- - ensure pre-requisites are met (see above)
- - place xenballoon.conf in <SYSCONFIG>
- - place xenballoond in /usr/sbin
- - copy xenballoond.init to <INITD_DIR>/xenballoond (note file rename)
- - edit <SYSCONFIG>/xenballoond.conf as desired (especially note that
- selfballooning defaults as off)
- - start xenballoond with "service xenballoond start", and/or configure
- xenballoond to start at init
- (Red Hat e.g. "chkconfig xenballoond on")
- (Debian e.g. " update-rc.d xenballoond defaults")
- (Suse e.g. " insserv xenballoond")
-- in domain0:
- - if monitoring is desired, xenballoon-monitor may be installed in /usr/sbin
-- note that certain xenballoond.conf variables may be overridden by domain0
- if xenstore is running in the guest; these are fully documented in
- xenballoond.conf
-
-TODO:
-080630 domain0 ballooning policy module
-080630 experiment with more aggressive (optionally) memory minimum targets
-080630 BUG: xenballoond doesn't properly record the fact that it's running;
- e.g. flipping between run levels 5 and 3 launches additional daemons
-080630 BUG: reports of possible incompatibilites between ballooning and
- save/restore/migrate have not been duplicated
