1. Converts the shutdown driver and xend to use the store instead of
control messages,
2. Includes Anthony's xenstore notification code, and
3. Changes xend so that sysrq's are no longer sent as "special case"
shutdown messages. Store keys are cheap, so making the sysrq
delivery less obscure is good.
I think I have made all of the appropriate modifications to Xend, but
it is complex, so I may have missed something. Comments are welcome.

three patches to fix a problem with Xend starting consoled. consoled
depends on xenstored to be running and xenstored is started on demand in
Xend. The patches change xenstored to manage its own pidfile, and have
xend start actually start up xenstored.
and changes xm to simply exec /usr/libexec/xen/xc_console.
I've done a pretty good amount of testing and this seems to clear up all
of the Xend console issues in bugzilla.
This is a pretty big change to Xend though with a lot of deleted code so
I'd appreciate if people more familiar with the Xend codebase could look
through it critically.
In addition to the patch, the following files are no longer used:

xenstore instead of control messages.
Note: Because there is no way to set a watch on a non-existent key,
this patch includes a workaround to account for the fact that dom0's
store keys are not initialized by the tools before it boots.

- Enforce the number of CPUs dom0 will take. See the new variable
"dom0-cpus" in xend-config.sxp (you will want to set this variable to
1 on SMP systems)
- Balloon out dom0 memory when creating domU, if there is not enough
free memory. The lowest level we will balloon out is configured via
the new variable "dom0-min-mem" in xend-config.sxp
I still have a doubt: where to put the code to enforce dom0-cpus. At
the moment I put it into
python/xen/xend/server/SrvDaemon.py, and hopefully that is resonable
enough. Any comment?

When a dom runs on multiple physical cpus, the CPU field doesn't have
much meaning. The suggested fix was to replace the value with '-'.

which gets rid of the -1 -> # hack and works for cpus > 9.
I ran into some issues with stale vcpu_to_cpu lists when running the
hotplug subprogram. I would take a vcpu offline, and then issue the
command to bring it back and the vcpu_to_cpu list would not have changed
to indicate the the vcpu actually went down. If I injected a xm list -v
(which always showed the correct mapping) then subsequent hotplug
commands would see the state change and fire off the hotplug request. I
don't know that not sending the event when not changing state saves that
much work so I took the state check out and now just send the hotplug
event directly.

I don't fully understand all of the mappings that are happening, so this
part of the patch might be way off. In any case, I've added a new
evtchn op to set the notify_vcpu_id field of a channel. I updated the
HOTPLUG_CPU code to use the new routines when bringing cpus up and down.
When taking down a cpu, I route the IPI irq channels to CPU 0, and when
the cpu comes up, it re-routes the channels back to the awakened CPU.

[PATCH] Device model cleanup.
Device model cleanup.
- Single config file for xen and device models
(Shell script doesn't source xmdefconfig anymore)
- No more device-model shell script by default. You can
have one if needed (qemu-dm.debug)
- All logic in the script device-model is moved to python
- $DISPLAY is passed from xm to xend
- Don't fork vncviewer on dryruns
- Add support for killing device models on domain destroy
- info vmxiopage command added to the monitor
- Refactor shared io page into global and per vcpu state
- Remove the hard coding of IOPACKET_PORT
- move the virtual_platform_def up to domain struct from vcpu
- xm create -n:
