resource can co-exist in the resource label file and lead to errors
during operation.
Ensures that all resource file names are stored with absolute
path name and are unique. Setting labels of phy-resources, relative
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.

Introducing an OptionError exception to be used by all xm subcommands
to signal an error in the arguments. "xm" will catch these and output
the appropriate error and usage message.
Detailed Changes:
main.py:
* Cleaned up imports and moved warning filter outside of
import block.
* Converted usage parameters and description to a python
dict rather than strings to enable better usage help
formatting.
* Removed unused list_label domain command.
* Added cmdHelp() prints out usage message for any command
* Added shortHelp() prints out the default help message when
xm is invoked with no arguments.
* Added longHelp() prints out long help message when invoked
with xm --help or xm help.
* Added extra optional paramter to getDomains() so we can
tell Xend not to poll devices. This will speed up xm list.
(PENDING changes to Xend itself.)
* Changed all references where 'dom' actually means 'domid'
to use the correct name.
* Changed 'xm list' header format to use printf formatting style.
* Renamed xm_subcommand to xm_importcommand so it is more
clear what it is doing (all xm commands are subcommands!)
* Moved cpu_make_map() inside xm_vcpu_pin as an anonymous func.
* Use OptionError whenever an invalid option is detected in xm.
* Added proper catch and error printing for XendError and
OptionErrors in main().

xm dump-core [-L|--live][-C| --crash] <domID> [output path]
-L| --live Live dump:
By default, xm dump does an xm pause, unpause before and
after taking the dump, respectively. This option disables
the pause/unpause and simply takes the dump.
-C :| --crash crash dump:
This executes an xm destroy after the dump file is complete.
The output path is optional, and if it is not specified, the path will be
/var/xen/dump/<domU name>.<domU ID>.core
This command uses the existant dumpCore(), which has been used for
coredump when a domU crashed.
