Jake Wires b3fb1294fa [TAPDISK] add tapdisk support for image chaining 
Enables tapdisk to chain an arbitrary number of VDIs, propagating reads of
holes in children to their parent images.  Introduces two new functions to the
tapdisk interface to facilitate this.  Modifies the QCoW plugin to take
advantage of these changes, thus providing support for arbitrarily long chains
of QCoW image types.

jchesterfield@dhcp92.uk.xensource.com 0da81aa1d4 Added blktap support. Includes kernel driver (enabled as CONFIG_XEN_BLKDEV_TAP=y) and userspace tools. The userspace deamon (blktapctrl) is enabled by default when xend is activated. For further information on using and configuring blktap see tools/blktap/README. 2006-07-13 10:13:26 +01:00
