Keir Fraser ceb97ddf1c xend: Properly save/restore vnc/vfb configuration
In 19284:0942BAA2A088 provision was made for running vnc and sdl
simultaneously.  However, arrangements for saving and restoring the
new structure-configuration, and arrangements for allowing the new
code to load old savefiles, were not made.

This patch adds these facilities.  Amongst other things, HVM VNC
save/restore will now work properly again.

LiveMigration, the disconnecting of src-side is not transmitted to
dist-side. As a result, the error processing on the dist side is not

Keir Fraser 5534b7d986 xend: specify the slot for pass-through devices
Currently a slot may be specified for a hot-plug device,
but not for a pass-through device that is inserted at boot time.
This patch adds support for the latter.

The syntax is:
     BUS:DEV.FUNC[@VSLOT]
e.g: 0000:00:1d:0@7

This may be important as recent changes that allow any free PCI
slot to be used for pass-through (and hotplug) may case pass-through
devices to be assigned in different locations to before. Amongst
other things, specifying the slot will allow users to move them
back, if there is a need.

Keir Fraser cde518aa71 blktap: Move error signaling to blktapctrl
Until now the udev script for blktap devices needs to decide if to
signal success or failure to xend. As this script runs completely
independent of blktapctrl and tapdisk/ioemu which do the real work,
the udev script can't even theoretically know if tapdisk is happy.

This patch removes the udev script and replaces its checks by new
ones in libblktap.

Keir Fraser 3dc413c7bd blktapctrl: Fix too early close of pipes
Connections to ioemu have single_handler set, so they are closed as
soon as all images of a certain type are closed. This is wrong with
ioemu: All images that belong to the same domain are handled by the
same backend process (usually qemu-dm, but also tapdisk-ioemu for
domains without device model), regardless of the image type.

This patch checks for the same-domain condition for ioemu connections.

This is a corrected version of a patch commited as c/s 19250 and

the rest of the script.

Change deviceDestroy behavior to remove /vm/UUID/device/...
path only when force was used (as it already does so for both frontend
and backend) and do the removing from xen-hotplug-cleanup script when
we are sure the device is really not attached to the guest any more.
