[Xen-devel] [PATCH 0/4] xenstore: enhance runtime debug capabilities

[Juergen Gross <jgross@xxxxxxxx>]

Today xenstored supports logging only via a command line parameter.
This means that logging is either all the time off (default) or on.
To switch logging on the Xen host has to be rebooted as xenstored
isn't restartable.

This patch series changes this by using the XS_DEBUG wire command of
Xenstore to control various debug functions:

- switch logging on/off
- specify logfile to use
- write memory usage to file

This will enable the host administrator to control above functionality
without the need of specifying any additional command line parameters
of xenstored or to restart the host in case of debug information
needed.

Juergen Gross (4):
  xenstore: enhance debug command support
  xenstore: add support for changing log functionality dynamically
  xenstore: make memory report available via XS_DEBUG
  xenstore: remove memory report command line support
