Xend tries to rebuild the network configuration such as bridges and
vlan interfaces (in those bridges) when starting. Unfortunately this
fails on the first startup since the network script has not run, yet,
and for example created peth0. When restarting xend it works due to
the peth0 being there then. This patch moves the initialization of the
network to an earlier time in the xend initialization process to
mitigate this problem.

Recent changes to the setup of the peth0 interface have resulted in a
change of its MAC address. Previously it seems to have had a MAC
address of 'fe:ff:ff:ff:ff:ff', but now it has the same MAC address as
eth0. As a consequence to this the Xen-API code to create VLANs
(PIF.create_VLAN("peth0",...)) does not work anymore, since peth0 can
not be identified according to this previous criteria of fake MAC
address. This patch fixes this issue by identifying it through the
prefix 'peth'.

A domain is only authorized to run if it has a superset of Simple Type
Enforcement Types in its VM label compared to that of Domain-0, which
itself may not have all STEs available in a policy. This patch adds a
check for this into Xend and the necessary code support into Xen.

Add a domain name check and a UUID check to xm new command. The check
logic is as follows:
- If the UUID is not specified
- If a VM with same name exists
=> Update the config for that existing VM
- Else no vm with same name exists
=> Define a brand new VM with auto-generated UUID
- Else UUID is specified
- If a VM with same UUID exists
- If name is different
=> Error
- Else if name is same
=> Update the config for that existing VM
- Else no VM with same UUID exists
- If name is different
=> Define a branch new VM with that name
- Else if name is same
=> Error

This lets us verify that qemu has indeed stopped processing before
we start saving guest memory. Also allow qemu to continue processing
after the save has happened, instead of exiting immediately.

This patch adds labeling of virtual network interfaces to xend and
makes this manageable through the Xen-API. It's a feature that is
only usable if ACM is enabled in Xen and xend is used through the
xen-api. A labeled virtual network interface will be plugged into a
bridge where other domains with the same-labeled network interface are
connected to, so that only same-colored domains can communicate with
each other. The bridge should be connected to the outside world using
VLAN for isolation, extending the isolation beyond the local machine.
If a virtual machine is labeled with a VM label that only has one
Simple Type Enforcement Type then it is not necessary to label the
virtual network interface, but the color of the network interface is
determined from the VM's label. If, however, a virtual machine is
labeled with a VM label that has multiple Simple Type Enforcement
Types, then the explicit labeling of each virtual network interface is
required. To specify the label of a network interface, the vif line in
the VM's configuration file has been extended with parameters similar
use for specifying the label of the VM:
vif = ['policy=<policy name>,label=<resource label>']
This labels the VIF of the virtual machine for usage under the policy
'policy name' and labels it with the label 'resource label'.

Make the vTPM hotplug script use the UUID of the vTPM instance for
associating it with its instance number rather than the name of the
domain.
Also change the cleanup in the xm test to use the atexit mechanism
rather than explicitly calling a function to clean up.

When domains are destroyed/suspend-resume/migration using the Xen-API
things break due to the domid not having been reset. This patch fixes
this. This is the best place I found for fixing this problem. I could
not push this line into _stateSet() for the case of DOM_STATE_HALTED
and left a comment regarding this.

- Allow multiple ChineseWallTypes in a VM labels
- check for surfacing exceptions in the python code
- check for array sizes in the XML DOM in python
- properly display the labels when doing 'xm list --label' in xm's
non-Xen-API mode
- rely on the security checking hooks in xend to check access to the
block interface rather than doing this in xm.

This patch adds a couple of new commands for using the Xen-API
extensions for security policies. Older tools are converted to support
going through the Xen-API for their operations rather than doing the
operations directly in their own code.

This patch implements extensions for managing security policies in
xend. The XSPolicy and ACMPolicy classes provide the interface for the
Xen-API and implement functionality for setting, updating and
activating of a Xen security policy as well as labeling of virtual
machines and resources such as block devices. Labeling of network
devices will follow.
The acmpolicy class implements a compiler for translating an XML
policy into their binary format and provides functionality for
comparing a current policy against a new one when changing/updating a
policy.
The xspolicyadmin class administers the policy of the system.
Some of the xend-internal code deals with transforming the labeling
information from the S-Expression format into the new Xen-API
format. This is similar to much of the other code that is already
there.

This can potentially cause a whole machine crash, which I think has
been seen in the wild. The case in the wild was caused by xendomains
auto-resuming domains on reboot, so it wasn't even operator error.
There's no sane way to migrate or suspend domains with PCI devs,
so I disallow it completely.

I'm suggesting this change to make another tiny step towards the
ability to run the tools e.g. out of the build tree (so that multiple
different Xen versions can co-exist without the requirement to
re-install the respective version with each boot).
