domains with PV drivers loaded. This patch creates a new PV-on-HVM
module, reboot.ko, which, when loaded, creates control/reboot_module
in the store. The tools notice this, and disable the watch which would
normally destroy HVM domains which are the target of an xm shutdown
command, allowing the reboot module to shut the domain down cleanly.

paths will automatically be pre-pended with '/dev/'; labeling
file-resources with relative paths will raise an error.

For some slightly-crazy reason the blktap patches changed the name
of the SEXPR block containing the disk definition 'vbd' to 'tap', even
though merely changing the 'uname' fragement was sufficient. eg
(vbd (backend 0) (dev hda:disk) (uname file:/xen/rhel4x86_64.img)
(mode w) )
changes to
(tap (backend 0) (dev hda:disk) (uname tap:aio:/xen/rhel4x86_64.img)
(mode w) )
If you create a domain with xm, then xm runs pygrub client side which
works fine. If you create a domain by feeding a block of SEXPR to Xend
over its network port, then pygrub is run server side. The code in
XenD which decides which disk to run pygrub against only looks for
'device/vbd' in the SEXPR so fails to see any blktap disks.

that the VNC server from qemu listens on.
Defaults to only listen on 127.0.0.1
The old behaviour (listen on all interfaces) can be restored, by
- changing the system-wide default in /etc/xen/xend-config.sxp by adding:
(vnc-listen '0.0.0.0')
- changing individual domain config files by adding:
vnclisten="0.0.0.0"
Also allows specifying the hostname associated with an interface to limit
to that interface.

In the current xen-unstable.hg tree tough, XenD will always pass an
explicit '-vnc <display num>' parameter to qemu-dm, regardless of
whether 'vncunused' is set. So the 'vncunused' bit only takes effect
if the explicitly passed display already has something bound to it.
Consider what happens when the host machine has been up for a while -
the Domain ID's start getting very high. This plays havoc with
firewalls - for example an admin may know that only 10 domains will
ever be running at any time, so they should be able to simply open up
ports 5900 -> 5910.
The correct behaviour should be:
- If 'vncdisplay' is set, use that explicit display
- If 'vncunused' is set non-zero, allocate first port about 5900
- Allocate fixed port based on domain-ID

If a Xen guest has a bootloader configured, then it will fail to start
on a blktap image. The problem is blkdev_uname_to_file, which cannot
parse the "tap:aio:$filename" image strings: it tries to split the
string apart at ":" and assign the result to a 2-tuple, and this
results in a python error if the split results in three or more
strings.
The fix is to split only at the first ":", and then to split again
if we detect "tap:" as the image type.
