In order for HVM domains to provide emulated access to disks provided
by hotplug scripts, qemu needs access to a "cooked" version of the
disk. In the case of hotplug scripts, this "cooked" version is
available in the form of a block device passed to blkback. Make this
"cooked" version available to qemu.
This series also starts to work towards a rationalized interface to
the block hotplug scripts, on which hotplug scripts for FreeBSD can be
added.
Changes since v1:
- Split one of the patches into two
George Dunlap (8):
tools/hotplug: Add a "dummy" hotplug script for testing
libxl: Remove redundant setting of phyical-device
tools/hotplug: Write physical-device-path in addition to
physical-device
libxl: Move check for local access to a funciton
libxl: Rearrange qemu upstream disk argument code
libxl: Share logic for finding path between qemuu and pygrub
libxl: Allow local access for block devices with hotplug scripts
docs: Document block-script protocol
Ian Jackson (1):
DO NOT APPLY libxl: Change hotplug script interface to use
physical-device-path
