[Xen-devel] [PATCH v4 00/53] Support for modifying parameters at runtime

Currently parameters of the hypervisor (e.g. console log level) can be set via boot command line. Instead of having to reboot the system in case another setting is desired, being able to modify many of those parameters at runtime would be the better option. This patch series addresses this by
