Remove the old vtpm process model. It doesn't work very
well and is no longer supported.

In the stubdom case you can now specify sdl=1 and vnc=1 (again, both
can be selected at the same time) in the vfb configuration.
So instead of:
vfb = [ 'type=vnc' ]
now you have:
vfb = [ 'vnc=1,sdl=1' ]
the former configuration option is deprecated but still supported for
backward compatibility.

Xen-API already specifies these actions for the 'on_crash' domain exit
event. This patch makes them available for use in traditional domU
config files and through the xm tool as well.

In various places in documentation and code, IP addresses are provided
as examples, defaults, or dummy configuration. In general the
specific IP addresses used in Xen are not always appropriate. (For
example, 1.2.3.4 is used in a few places!)
The following addresses should be used:
* For examples and documentation, 192.0.2.0/24. (See RFC3330.)
* For defaults for private networks, a random network from RFC1918.
I have randomly selected 172.30.206.0/24 for this purpose and
documented this in at the only registry I know of,
www.ucam.org/cam-grin. This network should henceforth be used for
default configurations of local bridges, test networks, etc. in
Xen tools.
The following addresses should NOT be used:
* 10.0.*.*, 10.1.*.*, 192.168.0.*, 192.168.1.*, etc. Using these
addresses gives greatly increased likelihood of collision, as
ignorant network administrators and reckless middlebox vendors
often pick networks from the bottom of 10/8 and 192.168/16.
* 169.254.*.*. These are reserved for zeroconf (ad-hoc networking)
and should not be used for Xen private networks, bridges, etc.,
etc. Use of these addresses by Xen scripts causes trouble on hosts
(eg laptops) which find themselves in ad-hoc networking
environments. I think this is not hypothetical (!) since at least
one Linux distribution have specific code to detect this case and
cause Xen startup to fail iff the host already has an external
zeroconf address.
* 1.2.3.4. WTF !?
I have also used 127.0.255.255 in one place where apparently a dummy
address is needed (some Linux kernels won't accept a lack of an NFS
server address). If 127.0.255.255 is mistakenly used it is unlikely
to do any damage to real traffic even if it does escape into the
network at large.

entries in vif to guide the configuration. This is much less confusing.
Closes bug #440.
Change the example configuration files to match. Also change them to use the
XenSource OUI in the MAC addresses. Also change xm-test to match.
Remove the obsolete ipaddr configuration entry, and the backend_mac vif config
option.
Remove the preprocess_vifs function, folding it into the configure_vifs
function, and creating a simple comma_sep_kv_to_dict helper.
Remove the configure_vfr method, as it is unused.

CPUs a domains' vcpus can use. The older 'cpu' config option is
prepended to the list of cpus to use and will keep the behavior of
pinning VCPU0.
The cpus option supports ranges and negation, so:
cpus = "0-3,5,^1" produces -> [0,2,3,5]
The list is circular, so in a domain with the following config:
vcpus = 4
cpus = "0,3,7" # Use any of 0, 3, 7 for this domain.
would see vcpus 0-3 pinned to cpus 0,3,7,0 respectively.
Also, the pin operation is moved before the memory reservation as vcpu
to cpu mapping will be helpful for future NUMA work when trying to
allocate pages close to the physical cpus being used.
An update to the display of cpumap was needed to normalize the cpumap
values to the range of possible cpus.
I've also included some text for the xmdomain.cfg(5) man page.

This is Kurt Garloff's reworked network-bridge script:
* we got rid of ifconfig
* it works for netdev != eth0
* arp on and off are symmetric as are ifdown and ifup
* ifup will be passed the ifcfg config file name if needed
(the ifup may otherwise figure that the veth0 hardware is
NOT the same as the original ${netdev} and not use the same
config -- this happens on SUSE. Charles Coffing tracked this
one down.)
Plus Kurt's avoid-dash patch:
the network setup scripts on SUSE have trouble with the bridge
name xen-br0; they don't expect the '-'.
Arguably this should be fixed.
But I assume there's more scripts out there which may not like it,
so I suggest the following patch to rename xen-br0 to xenbr0.
Plus Charles Duffy's patch to support multiple bridges:
The attached patch allows the network-bridge script to be used to
generate multiple bridges corresponding to different physical
interfaces. It adds a new parameter, "vifnum", used to refer both to
the loopback interface to be used and to set defaults regarding the
physical interface and bridge name.
Thus, if one wishes to start xenbr0 on eth0 and xenbr1 on eth1, one
need only call:
network-bridge start ## vifnum is 0 by default
network-bridge start vifnum=1
...well, that and set loopback.nloopbacks=2 in the Dom0 kernel
parameters.
Plus renaming of virtnum to vifnum in Charles' patch, as requested by Ian Pratt.
Plus a fix to DevController to allocate vif IDs starting from 0 (i.e. vif2.0
is now domain 2's first vif, as opposed to vif2.1 in the recent past).
Plus tidying up inside network-bridge using some helper variables.

they actually take effect. Added behaviour "rename-restart" for debugging
purposes, that renames the domain out of the way, preserving it for debugging,
but starts a new domain too.
Add explicit remove of old domain paths when creating a new domain, to avoid
stale information affecting us (by shutting the domain down, for example).

Add an optional parameter (vcpus) to the xc_linux_build function replacing
the getenv() previously used and removing the requirement of using maxcpus
kernel parameter to limit the number of virtual cpus a guest uses. The value
can now be controlled in the domain configuration files.
The default value of 1 is set in XenDomainInfo.py but is overridden by
parsing the config value.
