+
+Clones a domU, and gives a new Host name, MAC address and possibly IP address.
+Once finished the new domU should boot without any additional configuration.
+Currently works with single NIC, and basic bridge setup. Tested with cloning
+a SLES10 install created from the SLES10 YaST Xen module.
+
+  -h, --help	       Display this help message.
+  -v, --version	       Display the version of this program.
+  --force	       Silently overwrite files when destination already exists.
+  -c		       Xen configuration directory which defaults to:
+		       $XEN_CONFIGS
+  -b		       Xen image base directory which defaults to:
+		       $XEN_BASE
+  -d		       Duplicate only, do not modify attributes.
+  -n		       Hostname to be used, if not specified the NewdomU name
+		       will be used.
+  -i		       IP address to be used, if not specified the IP address
+		       will not be changed.
+  -m		       MAC address to be used, if not specified a psuedo-random
+		       address will be used based on the ip address with the
+		       format: 00:16:3e:BB:CC:DD
+		       Where BB,CC,DD are the Hex octals of the IP address.
+  -p		       This script assumes that the second partition on any
+		       writable disk of the domU to be cloned holds the root
+		       file system in which attributes have to be changed.
+		       If this is not the case for you, you can specify the
+		       partition number using this flag.
+  -t		       If the SourcedomU uses a block device for its root/
+		       boot directory, you need to specify the new block
+		       device for NewdomU.
+
+From XENSource Networking WIKI (http://wiki.xensource.com/xenwiki/XenNetworking)
+Virtualised network interfaces in domains are given Ethernet MAC addresses. When
+choosing MAC addresses to use, ensure you choose a unicast address. That is, one
+with the low bit of the first octet set to zero. For example, an address
+starting aa: is OK but ab: is not.
+It is best to keep to the range of addresses declared to be "locally assigned"
+(rather than allocated globally to hardware vendors). These have the second
+lowest bit set to one in the first octet. For example, aa: is OK, a8: isn't.
+
+Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.
