Since then, an io completion notification mechanism for metadata writing has been added*. The kernel module, along with the the tools, consistently pass fsstress and dbench tests on both x86_64 and x86_32. These patches integrate dm-userspace into the xen tree and allow a cow domain to be created. Hopefully some people can start experimenting with it and we look forward to hearing some feedback. Cowd and its associated plugins are a bit rough right now, but they work, and we plan on smoothing things out in the near future. This patch is broken up into 6 parts: [1/6]: A patch to the xen kernel in the patches/ directory. Also the default config files will build dm_userspace as a module. [2/6]: Adds the base for cowd, the userspace tool, to the tools directory. [3/6]: Adds internal libdmu support to cowd [4/6]: The dscow plugin for cowd [5/6]: The qcow plugin for cowd [6/6]: A script to start the dm-userspace backend as well as an xm example configuration file. *http://lists.xensource.com/archives/html/xen-devel/2006-06/msg00372.html *http://lists.xensource.com/archives/html/xen-devel/2006-06/msg00773.html
