457d4ad99d Fix undefined reference to 'close_used_without_including_unistd_h'
Found while trying to cross-compile libvirt on Fedora 12 for Windows.
gnulib redefines 'close' to 'close_used_without_including_unistd_h'
in sys/socket.h if winsock2.h is present and unistd.h has not been
included before sys/socket.h. Reorder some includes to fix this.

156e36a238 Fix configure check for SASL
The option --with-sasl defaults to 'check', but an inverted test logic
lets the SASL check fail with an error instead of disabling SASL.
Fix the test logic so SASL support gets disabled if SASL is missing and
--with-sasl is set to check.

cf30da7a25 Fix GnuTLS pkg-config check
The testlogic for $PKG_CONFIG was inverted, checking for an empty string
before using PKG_CHECK_MODULES. Use -x instead of -z and add an else branch
to the if checking for $GNUTLS_FOUND = no to add -lgcrypt in case the
GnuTLS libraries are detected by pkg-config.

e9f468d3f9 Make Xen VT-d PCI attach/detach work
The Xen code for making HVM VT-d PCI passthrough attach and detach
wasn't working properly:

1)  In xenDaemonAttachDevice(), we were always trying to reconfigure
a PCI passthrough device, even the first time we added it.  This was
because the code in virDomainXMLDevID() was not checking xenstore for
the existence of the device, and always returning 0 (meaning that
the device already existed).

2)  In xenDaemonDetachDevice(), we were trying to use "device_destroy"
to detach a PCI device.  While you would think that is the right
method to call, it's actually wrong for PCI devices.  In particular,
in upstream Xen (and soon in RHEL-5 Xen), device_configure is actually
used to destroy a PCI device.

To fix the attach
problem I add a lookup into xenstore to see if the device we are
trying to attach already exists.  To fix the detach problem I change
it so that for PCI detach (only), we use device_configure with the
appropriate sxpr to do the detachment.

* src/xen/xend_internal.c: don't use device_destroy for PCI devices
  and fix the other issues.
* src/xen/xs_internal.c src/xen/xs_internal.h: add
  xenStoreDomainGetPCIID()

c90e545f83 Fix detection of JSON when restarting libvirtd
The XML XPath for detecting JSON in the running VM statefile was
wrong causing all VMs to get JSON mode enabled at libvirtd restart.

In addition if a VM was running a JSON enabled QEMU once, and then
altered to point to a non-JSON enabled QEMU later the 'monJSON'
flag would not get reset to 0.

469b6b3a75 Fix reporting of TLS connection errors
The code for connecting to a server tries each socket in turn
until it finds one that connects. Unfortunately for TLS sockets
if it connected, but failed TLS handshake it would treat that
as a failure to connect, and try the next socket. This is bad,
it should have reported the TLS failure immediately.

$ virsh -c qemu://somehost.com/system
error: unable to connect to libvirtd at 'somehost.com': Invalid argument
error: failed to connect to the hypervisor

$ ./tools/virsh -c qemu://somehost.com/system

2c345831a3 python: Add python bindings for virDomainMemoryStats
Enable virDomainMemoryStats in the python API.  dom.memoryStats() will return a
dictionary containing the supported statistics.  A dictionary is required
because the meaining of each quantity cannot be inferred from its index in a
list.

* python/generator.py: reenable bindings for this entry point
* python/libvirt-override-api.xml python/libvirt-override.c: the
  generator can't handle this new function, add the new binding,

b6798b68cb Add a new command dommemstats for virDomainMemoryStats
Define a new command 'dommemstats' to report domain memory statistics.  The
output format is inspired by 'domblkstat' and 'domifstat' and consists of
tag/value pairs, one per line.  The command can complete successfully and
print no output if virDomainMemoryStats is supported by the driver, but not
the guest operating system.

Sample output:
swap_in 0
swap_out 0
major_fault 54
minor_fault 58259
unused 487680
available 502472

All stats referring to a quantity of memory (eg. all above except major and
minor faults) represent the quantity in KBytes.

* tools/virsh.c: implements the new command

c7523b410a Implements domainMemStats in the qemu driver
Support for memory statistics reporting is accepted for qemu inclusion.
Statistics are reported via the monitor command 'info balloon' as a comma
seprated list:

(qemu) info balloon
balloon: actual=1024,mem_swapped_in=0,mem_swapped_out=0,major_page_faults=88,minor_page_faults=105535,free_mem=1017065472,total_mem=1045229568

Libvirt, qemu, and the guest operating system may support a subset of the
statistics defined by the virtio spec.  Thus, only statistics recognized by
components will be reported.

* src/qemu/qemu_driver.c src/qemu/qemu_monitor_text.[ch]: implement the
  new entry point by using info balloon monitor command

470764f0b4 esx: Destroy virtual machine on a vCenter if available
If a virtual machine is destroyed on a ESX server then immediately
undefining this virtual machine on a vCenter may fail, because the
vCenter has not been informed about the status change yet. Therefore,
destroy a virtual machine on a vCenter if available, so the vCenter
is up-to-date when the virtual machine should be undefined.

directly: FindByUuid().

1c5c63338c Fix compilation with gcrypt < 1.4.2
Commit 33a198c1f6 increased the gcrypt
version requirement to 1.4.2 because the GCRY_THREAD_OPTION_VERSION
define was added in this version.

The configure script doesn't check for the gcrypt version. To support
gcrypt versions < 1.4.2 change the virTLSThreadImpl initialization
to use GCRY_THREAD_OPTION_VERSION only if it's defined.

  after the conftest.c source file and the tests are done properly.

7286882c34 Adds CPU selection infrastructure
Each driver supporting CPU selection must fill in host CPU capabilities.
When filling them, drivers for hypervisors running on the same node as
libvirtd can use cpuNodeData() to obtain raw CPU data. Other drivers,
such as VMware, need to implement their own way of getting such data.
Raw data can be decoded into virCPUDefPtr using cpuDecode() function.

When implementing virConnectCompareCPU(), a hypervisor driver can just
call cpuCompareXML() function with host CPU capabilities.

For each guest for which a driver supports selecting CPU models, it must
set the appropriate feature in guest's capabilities:

    virCapabilitiesAddGuestFeature(guest, "cpuselection", 1, 0)

Actions needed when a domain is being created depend on whether the
hypervisor understands raw CPU data (currently CPUID for i686, x86_64
architectures) or symbolic names has to be used.

Typical use by hypervisors which prefer CPUID (such as VMware and Xen):

- convert guest CPU configuration from domain's XML into a set of raw
  data structures each representing one of the feature policies:

    cpuEncode(conn, architecture, guest_cpu_config,
              &forced_data, &required_data, &optional_data,
              &disabled_data, &forbidden_data)

- create a mask or whatever the hypervisor expects to see and pass it
  to the hypervisor

Typical use by hypervisors with symbolic model names (such as QEMU):

- get raw CPU data for a computed guest CPU:

    cpuGuestData(conn, host_cpu, guest_cpu_config, &data)

- decode raw data into virCPUDefPtr with a possible restriction on
  allowed model names:

    cpuDecode(conn, guest, data, n_allowed_models, allowed_models)

- pass guest->model and guest->features to the hypervisor
