The current code will break if there are multiple scope global routes
since the "ip route list default" command doesn't use "default" as a
filter, and will output multiple devices which breaks the rest of the
script.
Also make the vif/xenbr/eth naming consistent, i.e. if your default
network interface is eth1, you get vif1 and xenbr1.

virtual machine and handles this for the virtual TPM (results in a no-op
for local migr.). If migration of a virtual machine with attached vTPM
to another machine is attempted, XenD will return an error.

drive image or a TPM, to be migrated to a remote machine. The patch
hooks into the checkpointing (XendCheckpoint.py) code and performs
migration in 4 different steps:
In a 1st step (step = 0 in the code) migration of all devices of a
domain is 'tested', that means their driver implementations (blkif.py,
netif.py, tpmif.py, usbif.py, pciif.py) are queried whether migration is
possible at all. Currently all device representations respond with a
'yes' (=0), although probably a VM mounting a hard drive partition
should respond with a 'no' (-1) already. This first step is a quick
check to see whether devices can be migrated.
The 2nd step is to do whatever can be done before the domain is
suspended. At this point migration of the device could be initiated, if
at all possible.
The 3rd step is to migrate a device after the domain has been suspended,
meaning that it is not scheduled anymore and the VM is 'settled'. All
devices are called again and a good implementation would initiate the
migration in a background process to achieve as much concurrency as
possible.
The 4th step is to synchronize with the 3rd step. At this point the
implementor has to make sure that anything that was initiated in step 3
has completed. Once all steps 4 have been processed, the VM will resume
on the remove machine.
I have implemented hooks for migration of a virtual TPM in
xen/xend/server/tpmif.py. These hooks call a configurable external
migration tool using the os.popen() call with a fixed command line
parameter set. The implementation refuses to migrate a VM attached to a
virtual TPM if no tool has been provided for migration.
All other devices do not currently overload the 'migrate' method defined
in the DevController.py and therefore will just let migration happen.
I have added hooks for error recovery such that whatever part of
migration has been initiated can be rolled back when any of the devices
fail to migrate in one of the steps. The interface (in tpmif.py) to the
external application now uses os.popen() to allow error handling by
reading the application's output.

There are two possible root causes for 515, both of which are only problems in the non-udev hotplug case because udev uses udevsend which already implements the required serialisation.
1) Script concurrency.
2) Kernel reordering hotplug events.
This changeset fixes (1) but not (2). Since (1) is the problem that seems to be happening this is probably OK.
A fix for (2) for the hotplug case might be to add extra serialisation using state changes in the store but this would impact all the drivers and the code and extra complexity would be redundant once everyone had moved to udev. This doesn't seem worthwhile unless we actually start to see (2) happening.
DESTDIR is empty, by preventing readlink from being called in that
case.
Another option would be to use readlink -s, but that has the
undesirable effect of staying silent in situations other than empty

- introduces two basic tests for the virtual TPM (skipped on hardware
where a TPM is not available or vtpm manager has not been started
manually before)
- adapts the Makefiles to make the test cases available
- splits up the hotplug files into two files where the vtpm-common.sh
can be sourced by 'other' scripts as well
- uses echo "$var" to return variables from functions
- gets rid of the 'set +e" work-around
- introduces a script (vtpm-delete) to delete entries from the virtual
TPM directory in /etc/xen/vtpm.db
The xm-tests will skip over the 2nd test on most systems and the patch
has otherwise no effect on existing tests.

- locking-related functions from xen-hotplug-common.sh -> locking.sh
- xen-hotplug-common.sh 'sources' both those files now to not loose
these functions (which should make the break-out atomic)
- adapts the Makefile to install locking.sh and logging.sh at the right
place.
I ran the xm-tests over it and no (additional) errors appear due to this

This is done by defining ifup/down both to 'false' when they're
missing; then instead of attempting to parse the IP params from
the kernel command line, we get them from 'ip' instead. So this
works even with (for example) ip=dhcp on the kernel command line.
Also made a few minor syntax changes (in particular, replaced "=="
with "=", and ">&foo" with ">foo 2>foo") so this works with more
limited shells.
