Since we moved several NUMA info fields from physinfo into separate
functions/structures, we must adapt the node picking algorithm, too.
Currently xm create complains about undefined hash values.
The patch uses the new Python xc binding to get the information and
create a reverse mapping for node_to_cpu, since we now only have a
cpu_to_node field.

'xm info' command now also gives the cpu topology & host numa
information. This will be later used to build guest numa support. The
patch basically changes physinfo sysctl, and adds topology_info &
numa_info sysctls, and also changes the python & libxc code
accordingly.

c/s 21040 and 21044 used to break cpu number limit (<=64).
However, they result in bug under ia32pae model:
1. things will go wrong for affinity, making all vcpus pin to a same
cpu with same time;
2. when 'xm vcpu-pin' vpu to cpu, xend will exit abnormally.
This patch is to fix the bugs described above.

Currently qemu has a bug: When maxvcpus > 64, qemu will get wrong
vcpu bitmap (s->cpus_sts[i]) since it only get bitmap from a long
variable.
This patch, cooperate with another qemu patch, is to fix this bug.
This patch transfer a vcpu_avail string in a hex string format, so
that at qemu side it's more easier to get vcpu bitmap from hex string,
especially when many vcpus, like more than 64.
(Also update QEMU_TAG for matching qemu-side update)

In order to have better chance that relevant messages fit into the
ring buffer, allocate a dynamic (larger) one in more cases, and make
the default allocation size depend on both the number of CPUs and the
log level. Also free the static buffer if a dynamic one was obtained.
In order for "xm dmesg" to retrieve larger buffers, eliminate
pyxc_readconsolering()'s 32k limitation resulting from the use of a
statically allocated buffer.
Finally, suppress on x86 most per-CPU boot time messages (by default,
most of them can be re-enabled with a new command line option
"cpuinfo", some others are now only printed more than once when there
are inconsistencies between CPUs). This reduces both boot time (namely
when a graphical console is in use) and pressure on the console ring
and serial transmit buffers.

Domain exit actions that contain a hyphen (e.g. rename-restart) were
not being detected properly when xm is configured to use xenapi.
Domain config containing on_crash=3D"rename-restart" results in
xen53:~ # xm new /tmp/domU.config
Using config file "/tmp/domU.config".
Unexpected error: <type 'exceptions.TypeError'>
This patch fixes the raised exception and at the same time
handles the replacement of hyphen with underscore properly.

Sometimes PV domain with vfb doesn't boot up. /sbin/kudzu is stuck.
After investigation, I've found that the evtchn for console is not
bound at all.
Normal sequence of evtchn initialization in qemu-dm for xenpv is:
1) watch xenstore backpath (/local/domain/0/backend/console/<domid>/0)
2) read console info (/local/domain/<domid>/console/{type, ring-ref,
port..=
})
3) bind the evtchn to the port.
But in some case, xend writes to the backpath before the console info
is prepared, and never write to the backpath again. So the qemu-dm
fails at 2) and never reach to 3).
When this happens, manually xenstore-write command on Domain-0
resumes the guest.

nodes without memory will currently be disabled by also moving the
physical cores connected to them to other nodes. This leads to nodes
without CPUs and thus to a division by zero in the node allocation
algorithm. Attached patch fixes this by checking for 0 before the
division. This fixes domain creation on boxes with memory-less nodes.

pci global options and per-device options for HVM device model have
been broken for some time, the patch tries to fix the problem. It:
* maintains global options in xend, and merge it into
per-device option when creating the backend
* merge the global options also into the parameter of pci-ins
dm-command
The second one is there because the backend is effectively skipped
in ioemu at present, ioemu solely relies on the parameter string to
create the device.

To workaround a race condition about guest hotplug, c/s
18338:7c10be016e4 disabled do_FLR when we create guest or 'xm

patch re-enables do_FLR in these 2 cases disabled by 18338.
