+Xen Control Tools - Examples
+===================================
+
+This directory contains example scripts and configurations for Xen.
+For many operations you will either be able to use these scripts directly, or
+incorporate code from them into your own scripts.
+
+If you write a useful script and would like to share it, please do
+send it (preferably with a little summary to go in this file) to
+<xen-devel@lists.sourceforge.net> so we can add it to this directory.
+
+block               - called by xen-backend.agent to bind/unbind dev  
+block-common.sh     - sourced by block, block-*
+block-enbd          - binds/unbinds network block devices
+block-nbd           - binds/unbinds network block devices
+external-device-migrate - called by xend for migrating external devices
+locking.sh          - locking functions to prevent concurrent access to
+                      critical sections inside script files
+logging.sh          - logging function to log output using syslog
+network-bridge      - xen network start/stop script when using bridging
+network-nat         - xen network start/stop script when using NAT
+network-route       - xen network start/stop script when using routing

+vif-route           - xen virtual network start/stop script in routed mode
+vtpm                - called by xen-backend.agent to bind/unbind vTPM devices
+vtpm-common.sh      - common code for vTPM handling
+vtpm-delete         - remove an entry from the vTPM table given the
+                      domain's name
+vtpm-hotplug-common.sh - sourced by vtpm
+vtpm-migration.sh   - sourced by external-device-migrate
+xen-backend.agent   - calls block, vif-*, vtpm scripts to add, remove, hotplug
+                      devices

+xmexample2          - a more complex configuration script for 'xm create'
+xmexample3          - an advanced configuration script for 'xm create' 
+                      that utilizes the vmid
+xmexample.nbd       - configuration script that uses NBD filesystems
+xmexample.hvm       - a configuration script for creating a hvm domain with

+Command Incompatibilities
+=========================
+
+Known incompatibilities with various commands on various distributions, and
+the workarounds we use.
+
+
+brctl
+-----
+
+brctl show <bridge> fails on SLES9 SP2.  Workaround is to use brctl show
+without arguments, and grep, though this would be difficult were you to need
+to check for a specific bridge-interface pair, since brctl does not show the 
+bridge name on every line.
+
+
+ifup / ifdown
+-------------
+
+SuSE requires an extra parameter to ifup, which is created by calling getcfg
+appropriately.  See xen-network-common.sh for details.
+
+Gentoo doesn't have ifup/ifdown; appropriate alternatives are defined in
+xen-network-common.sh.
+
+
+ip
+--
+
+Newer ip commands (from iproute2) do not accept the abbreviated syntax "ip r a
+..." etc.  "ip route add ..." must be used instead.
+
+
+sed
+---
+
+\s is not supported in regexps on Debian etch (sed 4.1.2), Ubuntu 4.10.  We
+hand-craft character classes instead.

+#  'x' -> Get a safe value (pass through and mask with the default policy)
+#  'k' -> pass through the host bit value
+#  's' -> as 'k' but preserve across save/restore and migration
+# 
+#   Expose to the guest multi-core cpu instead of multiple processors

+#  - CPUID.1[EDX] : Mask some features
+#  - CPUID.4 : Reply like the highest leaf, in our case CPUID.3
+#  - CPUID.0x80000000 : No extension we are on a Pentium III, reply like the

+#   Configure host CPUID consistency checks, which must be satisfied for this
+#   VM to be allowed to run on this host's processor type:
+#cpuid_check=[ '1:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxx1xxxxx' ]
+# - Host must have VMX feature flag set
+#
+# The format is similar to the above for 'cpuid':
+#  '1' -> the bit must be '1'
+#  '0' -> the bit must be '0'
+#  'x' -> we don't care (do not check)

+# Description:
+#
+# This script is used to enable or disable the VM relocation (migration)

+#  or both the local instance and instances of xend on the other machines
+#  to/from which VMs can be relocated.
+# To manage the instances of xend on other machines this script communicates
+#  using ssh so it is recomended that if you use this feature you 
+#  pre-distribute ssh keys between the servers.

+# Depends on:

+# Usage:             xend-relocation (start|stop|status)

+
+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.

+  --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.

+# Synopsis of lock-util:
+# lock-util [-l|-u] -n <vm name> -i <vm uuid> -p <physical host> path"
+# -l          Acquire (create) lock
+# -u          Remove lock
+# -n vm-name  Name of domain
+# -i vm-id    Id or UUID of domain
+# -p phy-host Name of physical host (dom0)
+# path        /<xend-domain-lock-path>/<vm-uuid>
+# Return 0 on success, non-zero on error.
+#
+# lock-util [-s] path"
+# -s          Lock status.  If lock is acquired, print any contents
+#             on stdout and return 0.  Return non-zero if lock is
+#             available.
+# path        /<xend-domain-lock-path>/<vm-uuid>
+# If lock is acquired, print any contents on stdout and return 0.
+# Return non-zero if lock is available.
+#
+# Default lock-util behavior:
+# On domain start event, domain-lock will create and flock(1)
+# /<xend-domain-lock-path>/<vm-uuid>/lock.  Every two seconds it
+# will write <vm-name>, <vm-id>, <vm-host>, and <tick> to the lock.
+# <tick> is running counter.
+# On domain stop event, domain-lock will unlock and remove
+# /<xend-domain-lock-path>/<vm-uuid>/lock.
+#
+# Note: If xend-domain-lock-path is a cluster-unaware file system,
+#       administrator intervention may be required to remove stale
+#       locks.  Consider two hosts using NFS for xend-domain-lock-path
+#       when HostA, running vm1, crashes.  HostB could not acquire a
+#       lock for vm1 since the NFS server holds an exclusive lock
+#       acquired by HostA.  The lock file must be manually removed
+#       before starting vm1 on HostA.
