f7dd3a4e62 Add support for cpu mode attribute
The mode can be either of "custom" (default), "host-model",
"host-passthrough". The semantics of each mode is described in the
following examples:

- guest CPU is a default model with specified topology:
    <cpu>
      <topology sockets='1' cores='2' threads='1'/>
    </cpu>

- guest CPU matches selected model:
    <cpu mode='custom' match='exact'>
      <model>core2duo</model>
    </cpu>

- guest CPU should be a copy of host CPU as advertised by capabilities
  XML (this is a short cut for manually copying host CPU specification
  from capabilities to domain XML):
    <cpu mode='host-model'/>

  In case a hypervisor does not support the exact host model, libvirt
  automatically falls back to a closest supported CPU model and
  removes/adds features to match host. This behavior can be disabled by
    <cpu mode='host-model'>
      <model fallback='forbid'/>
    </cpu>

- the same as previous returned by virDomainGetXMLDesc with
  VIR_DOMAIN_XML_UPDATE_CPU flag:
    <cpu mode='host-model' match='exact'>
      <model fallback='allow'>Penryn</model>       --+
      <vendor>Intel</vendor>                         |
      <topology sockets='2' cores='4' threads='1'/>  + copied from
      <feature policy='require' name='dca'/>         | capabilities XML
      <feature policy='require' name='xtpr'/>        |
      ...                                          --+
    </cpu>

- guest CPU should be exactly the same as host CPU even in the aspects
  libvirt doesn't model (such domain cannot be migrated unless both
  hosts contain exactly the same CPUs):
    <cpu mode='host-passthrough'/>

- the same as previous returned by virDomainGetXMLDesc with
  VIR_DOMAIN_XML_UPDATE_CPU flag:
    <cpu mode='host-passthrough' match='minimal'>
      <model>Penryn</model>                        --+ copied from caps
      <vendor>Intel</vendor>                         | XML but doesn't
      <topology sockets='2' cores='4' threads='1'/>  | describe all
      <feature policy='require' name='dca'/>         | aspects of the
      <feature policy='require' name='xtpr'/>        | actual guest CPU
      ...                                          --+
    </cpu>

a6f88cbd2d cpu: Optionally forbid fallback CPU models
In case a hypervisor doesn't support the exact CPU model requested by a
domain XML, we automatically fallback to a closest CPU model the
hypervisor supports (and make sure we add/remove any additional features
if needed). This patch adds 'fallback' attribute to model element, which
can be used to disable this automatic fallback.

bbae92f8b8 tests: Add fake PPC64 emulator for QEMU testing
Create a fake PPC64 QEMU so that we can run PPC64 QEMU tests when we
don't have a real version of the emulator available.

209c2880b9 Fix default console type setting
The default console type may vary based on the OS type. ie a Xen
paravirt guests wants a 'xen' console, while a fullvirt guests
wants a 'serial' console.

A plain integer default console type in the capabilities does
not suffice. Instead introduce a callback that is passed the
OS type.

* src/conf/capabilities.h: Use a callback for default console
  type
* src/conf/domain_conf.c, src/conf/domain_conf.h: Use callback
  for default console type. Add missing LXC/OpenVZ console types.
* src/esx/esx_driver.c, src/libxl/libxl_conf.c,
  src/lxc/lxc_conf.c, src/openvz/openvz_conf.c,

  src/uml/uml_conf.c, src/vbox/vbox_tmpl.c,
  src/vmware/vmware_conf.c, src/xen/xen_hypervisor.c,
  src/xenapi/xenapi_driver.c: Set default console type callback

aa3b2e40f5 tests: Fake host capabilities properly
Since we fake host CPU we should also fake host arch instead of taking
the real architecture tests are running on.

a71be01f04 Add tests for the new Qemu namespace XML.
Thanks to DV for knocking together the Relax-NG changes
quickly for me.

Changes since v1:
 - Change the domain.rng to correspond to the new schema
 - Don't allocate caps->ns in testQemuCapsInit since it is a static table

Changes since v2:
 - Change domain.rng to add restrictions on allowed environment names

Changes since v3:
 - Remove a bogus comment in the tests

af53714f47 cpu: Add support for CPU vendor
By specifying <vendor> element in CPU requirements a guest can be
restricted to run only on CPUs by a given vendor. Host CPU vendor is
also specified in capabilities XML.

The vendor is checked when migrating a guest but it's not forced, i.e.,
guests configured without <vendor> element can be freely migrated.

e8ac4a79f1 Make test suite output less verbose
Only print out '.' for each test case, full test output can be
re-enabled with VIR_TEST_VERBOSE=1, or VIR_TEST_DEBUG=XXXX

Sample output now looks like

  TEST: statstest
        ........................................ 40
        ...................................      75  OK
  PASS: statstest
  TEST: qparamtest
        ................................         32  OK
  PASS: qparamtest
  TEST:
        ............                             12  OK

9710856b33 tests: Centralize VIR_TEST_DEBUG lookup, and document it
Provide a simple interface for other tests to lookup the testDebug variable.
Also remove a redundant error message in interface tests.

If anyone feels inclined to change this env variable to match the existing
LIBVIRT_* format, it should now be easier to do so.

38fd207e53 Add virCapsGuestMachine structure
A subsequent commit will add a "canonical" field to this structure,
this patch basically just prepares the way for that.

The new type is added, along with virCapabilitiesAlloc/FreeMachines()
helpers and a whole bunch of code to make the transition.

One quirk is that virCapabilitiesAddGuestDomain() and
virCapabilitiesAddGuest() take ownership of the machine list rather
than duping it. This makes sense to avoid needless copying.

* src/capabilities.h: add the virCapsGuestMachine struct and use it
  in virCapsGuestDomainInfo, add prototypes for new functions and
  update the AddGuest() prototypes

* src/capabilities.c: add code for allocating and freeing the new
  type, change the machines parameter to AddGuest() etc.

* src/libvirt_private.syms: export the new helpers

* src/qemu_conf.c: update all the machine type code to use the new
  struct

* src/xen_internal.c: ditto

* tests/testutilsqemu.c: ditto
