Some kernel versions expose broken NUMA topology for some machines.
This causes the LXC/UML drivers to fail to start. QEMU driver was
already fixed for this problem

* src/lxc_conf.c: Log and ignore failure to populate NUMA info
* src/uml_conf.c: Log and ignore failure to populate NUMA info
* src/capabilities.c: Reset nnumaCell to 0 after freeing

Certain drivers always need an 'emulator' specified in the XML (qemu and lxc
at least). Store this info in capabilities.

We will eventually use this to move default emulator handling out of
drivers and into domain_conf.*

* src/uml_conf.c (VIR_FROM_THIS): Define to VIR_FROM_UML.
* src/xs_internal.c (VIR_FROM_THIS): Define to VIR_FROM_XEN.
* src/xml.c (VIR_FROM_THIS): Define to VIR_FROM_XML.
* src/stats_linux.c (VIR_FROM_THIS): Define to VIR_FROM_STATS_LINUX.
* src/datatypes.c (VIR_FROM_THIS): Define to VIR_FROM_NONE.
* src/lxc_conf.c (VIR_FROM_THIS): Define to VIR_FROM_LXC.
* src/libvirt.c (VIR_FROM_THIS): Define to VIR_FROM_NONE.
* src/node_device_conf.c (VIR_FROM_THIS): Define to VIR_FROM_NODEDEV.
* src/openvz_conf.c (VIR_FROM_THIS): Define to VIR_FROM_OPENVZ.
* src/openvz_driver.c (VIR_FROM_THIS): Define to VIR_FROM_OPENVZ.
* src/conf.c (VIR_FROM_THIS): Define to VIR_FROM_CONF.
Note: this loses config_filename:config_lineno diagnostics,
but that's ok.
* src/node_device.c (VIR_FROM_THIS): Define to VIR_FROM_NODEDEV.
* src/sexpr.c (VIR_FROM_THIS): Define to VIR_FROM_SEXPR.
* po/POTFILES.in: remove src/sexpr.c and src/lxc_conf.c

qemudCapsInitNUMA and umlCapsInitNUMA were identical, so this change
factors them into a new function, virCapsInitNUMA, and puts it in
nodeinfo.c.

In addition to factoring out the duplicates, this change also
adjusts that function definition (along with its macros) so
that it works with Fedora 9's numactl version 1, and makes it
so the code will work even if someone builds the kernel with
CONFIG_NR_CPUS > 4096.

Finally, also perform this NUMA initialization for the lxc
and openvz drivers.

* src/nodeinfo.c: Include <stdint.h>, <numa.h> and "memory.h".
(virCapsInitNUMA): Rename from qemudCapsInitNUMA and umlCapsInitNUMA.
(NUMA_MAX_N_CPUS): Define depending on NUMA API version.
(n_bits, MASK_CPU_ISSET): Define, adjust, use uint64 rather than long.
* src/nodeinfo.h: Include "capabilities.h".
(virCapsInitNUMA): Declare it.
* examples/domain-events/events-c/Makefile.am:
* src/Makefile.am: Add $(NUMACTL_CFLAGS) and $(NUMACTL_LIBS) to various
compile/link-related variables.
* src/qemu_conf.c: Include "nodeinfo.h".
(qemudCapsInitNUMA): Remove duplicate code.  Adjust caller.
* src/uml_conf.c (umlCapsInitNUMA): Likewise.
Include "nodeinfo.h".
* src/lxc_conf.c: Include "nodeinfo.h".
(lxcCapsInit): Perform NUMA initialization here, too.
* src/openvz_conf.c (openvzCapsInit): And here.
Include "nodeinfo.h".
* src/libvirt_sym.version.in: Add virCapsInitNUMA so that libvirtd
can link to this function.

* src/lxc_conf.c (lxcLoadDriverConfig): Mark a diagnostic.
* src/lxc_driver.c (lxcDomainStart): Likewise.
* po/POTFILES.in: Add src/lxc_conf.c.
* Makefile.maint (msg_gen_function): Add virReportErrorHelper
and lxcError.

  src/lxc_container.h src/lxc_driver.c: Applied second set of
  linux container patches from Dave Leskovec adding start/stop
  of domains
Daniel

  access I introduced yesterday
Daniel

* src/lxc_conf.c src/lxc_conf.h: cleanup patch for the conf driver
  of linux countainers, reuse XPath helpers, make string fields dynamic
  and remove a memory leak.
* src/lxc_driver.c: avoid some problems when the config directory is
  not accessible and for regression tests
Daniel

* Makefile.maint (msg_gen_function): Add, but commented-out.
* src/lxc_conf.c (lxcParseXML): Mark a diagnostic for translation.

* src/lxc_conf.c src/lxc_conf.h src/lxc_driver.c src/remote_internal.c:
  applied patch from Dan Berrange to change the way the lxc driver
  works, migrating the support in the daemon, it also removes some
  compilation issues and teh way the configuration files are named.
Daniel

* configure.in include/libvirt/virterror.h src/Makefile.am
  src/driver.h src/lxc_conf.[ch] src/lxc_driver.[ch] src/virterror.c:
  Applied 3 patches from Dave Leskovec for intial support of
  Linux containers, configured off by default, work in progress.
* src/libvirt.c: improve virDomainCreateLinux xmlDesc description
