numad is an user-level daemon that monitors NUMA topology and
processes resource consumption to facilitate good NUMA resource
alignment of applications/virtual machines to improve performance
and minimize cost of remote memory latencies. It provides a
pre-placement advisory interface, so significant processes can
be pre-bound to nodes with sufficient available resources.

More details: http://fedoraproject.org/wiki/Features/numad

"numad -w ncpus:memory_amount" is the advisory interface numad
provides currently.

This patch add the support by introducing a new XML attribute
for <vcpu>. e.g.

  <vcpu placement="auto">4</vcpu>
  <vcpu placement="static" cpuset="1-10^6">4</vcpu>

The returned advisory nodeset from numad will be printed
in domain's dumped XML. e.g.
  <vcpu placement="auto" cpuset="1-10^6">4</vcpu>

If placement is "auto", the number of vcpus and the current
memory amount specified in domain XML will be used for numad
command line (numad uses MB for memory amount):
  numad -w $num_of_vcpus:$current_memory_amount / 1024

The advisory nodeset returned from numad will be used to set
domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity).

If the user specifies both CPU affinity policy (e.g.
(<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto"
the specified CPU affinity will be overridden.

Only QEMU/KVM drivers support it now.

See docs update in patch for more details.

And don't allow to hotplug a usb disk with "device == lun". This
is the missed pieces in previous virtio-scsi patchset:

http://www.redhat.com/archives/libvir-list/2012-February/msg01052.html

With current code, we pass true iff domain is cold booting. However,
if disk is inaccessible and startupPolicy for that disk is set to
'requisite' we have to fail iff cold booting.

This patch adds support for the new tsc-deadline feature flag
and a new model to the supported model list describing the
Intel Sandy Bridge platform.

AMD Bulldozer (or Opteron_G4 as called in QEMU) was added to the list
of cpu models, flags were taken from upstream qemu cpu specifications
and should be sorted by bit values (or first occurence in the feature
specification part of cpu_map.xml).

Based on QEMU upstream commit 885bb0369a4f0abe2c0185178f3cb347cb02cdf1.

Even though we say in documentation setting (tls-)port to -1 is legacy
compat style for enabling autoport, we're roughly doing this for VNC.
However, in case of SPICE auto enable autoport iff both port & tlsPort
are equal -1 as documentation says autoport plays with both.

In qemuDomainDetachNetDevice, detach was being used before it had been
validated. If no matching device was found, this resulted in a
dereference of a NULL pointer.

This behavior was a regression introduced in commit
cf90342b, so it has not been a part of
any official libvirt release.

When host-model and host-passthrouh CPU modes were introduced, qemu
driver was properly modify to update guest CPU definition during
migration so that we use the right CPU at the destination. However,
similar treatment is needed for (managed)save and snapshots since they
need to save the exact CPU so that a domain can be properly restored.
To avoid repetition of such situation, all places that need live XML
share the code which generates it.

As a side effect, this patch fixes error reporting from
qemuDomainSnapshotWriteMetadata().

If there is a disk file with a comma in the name, QEmu expects a double
comma instead of a single one (e.g., the file "virtual,disk.img" needs
to be specified as "virtual,,disk.img" in QEmu's command line). This
patch fixes libvirt to work with that feature. Fix RHBZ #801036.

We found few more AMD-specific features in cpu64-rhel* models that
made it impossible to start qemu guest on Intel host (with this
setting) even though qemu itself starts correctly with them.
This impacts one test, thus the fix in tests/cputestdata/.

virNetworkDNSHostsDefParseXML was calling VIR_ALLOC(def->hosts) if
def->hosts was NULL. This is a waste of time, though, since
VIR_REALLOC_N is called a few lines further down, prior to any use of
def->hosts. (initializing def->nhosts to 0 is also redundant, because
the newly allocated memory will always be cleared to all 0's anyway).

One of the recent commits introduced support for
spice agent-mouse. However, test for this feature
require some tweaking: pass QEMU_CAPS_CHARDEV_SPICEVMC |
QEMU_CAPS_NODEFCONFIG and add "-vga cirrus".

If user hasn't supplied any tlsPort we default to setting it
to zero in our internal structure. However, when building command
line we test it against -1 which is obviously wrong.

The file daemon/probes.h used to be generated as part of a build, but
is no longer used. However, a stale copy of it lying around could
cause a build to fail. Removing it from .gitignore will make it more
likely someone will notice that they have it lying around.

This is nearly identical to an earlier patch for virnetlink.c.

There are special stub versions of all public functions in this file
that are compiled when the platform isn't linux. Each of these
functions had an almost identical message, differing only in the
function name included in the message. Since log messages already
contain the function name, we can just define a const char* with the
common part of the string, and use that same string for all the log
messages.

If nothing else, this at least makes for less strings that need
translating...

This function was freeing a virDomainNetDef with
VIR_FREE(). virDomainNetDef is a complex structure with many pointers
to other dynamically allocated data; to properly free it
virDomainNetDefFree() must be called instead, otherwise several
strings (and potentially other things) will be leaked.

For some reason, although live hotplug of <hostdev> devices is
supported, persistent hotplug is not. This patch adds the proper
VIR_DOMAIN_DEVICE_HOSTDEV cases to the switches in
qemuDomainAttachDeviceConfig and qemuDomainDetachDeviceConfig.

There are several functions that call virNetlinkCommand, and they all
follow a common pattern, with three exit labels: err_exit (or
cleanup), malformed_resp, and buffer_too_small. All three of these
labels do their own cleanup and have their own return. However, the
malformed_resp label usually frees the same items as the
cleanup/err_exit label, and the buffer_too_small label just doesn't
free recvbuf (because it's known to always be NULL at the time we goto
buffer_too_small.

In order to simplify and standardize the code, I've made the following
changes to all of these functions:

1) err_exit is replaced with the more libvirt-ish "cleanup", which
   makes sense because in all cases this code is also executed in the
   case of success, so labelling it err_exit may be confusing.

2) rc is initialized to -1, and set to 0 just before the cleanup
   label. Any code that currently sets rc = -1 is made to instead goto
   cleanup.

3) malformed_resp and buffer_too_small just log their error and goto
   cleanup. This gives us a single return path, and a single place to
   free up resources.

4) In one instance, rather then logging an error immediately, a char*
   msg was pointed to an error string, then goto cleanup (and cleanup
   would log an error if msg != NULL). It takes no more lines of code
   to just log the message as we encounter it.

This patch should have 0 functional effects.

There are several functions in domain_conf.c that remove a device
object from the domain's list of that object type, but don't free the
object or return it to the caller to free. In many cases this isn't a
problem because the caller already had a pointer to the object and
frees it afterward, but in several cases the removed object was just
left floating around with no references to it.

In particular, the function qemuDomainDetachDeviceConfig() calls
functions to locate and remove net (virDomainNetRemoveByMac), disk
(virDomainDiskRemoveByName()), and lease (virDomainLeaseRemove())
devices, but neither it nor its caller qemuDomainModifyDeviceConfig()
ever obtain a pointer to the device being removed, much less free it.

This patch modifies the following "remove" functions to return a
pointer to the device object being removed from the domain device
arrays, to give the caller the option of freeing the device object
using that pointer if needed. In places where the object was
previously leaked, it is now freed:

  virDomainDiskRemove
  virDomainDiskRemoveByName
  virDomainNetRemove
  virDomainNetRemoveByMac
  virDomainHostdevRemove
  virDomainLeaseRemove
  virDomainLeaseRemoveAt

The functions that had been leaking:

  libxlDomainDetachConfig - leaked a virDomainDiskDef
  qemuDomainDetachDeviceConfig - could leak a virDomainDiskDef,
                            a virDomainNetDef, or a
                            virDomainLeaseDef
  qemuDomainDetachLease   - leaked a virDomainLeaseDef

There were certain paths through the hostdev detach code that could
lead to the lower level function failing (and not removing the object
from the domain's hostdevs list), but the higher level function
free'ing the hostdev object anyway. This would leave a stale
hostdevdef pointer in the list, which would surely cause a problem
eventually.

This patch relocates virDomainHostdevRemove from the lower level
functions qemuDomainDetachThisHostDevice and
qemuDomainDetachHostPciDevice, to their caller
qemuDomainDetachThisHostDevice, placing it just before the call to
virDomainHostdevDefFree. This makes it easy to verify that either both
operations are done, or neither.

NB: The "dangling pointer" part of this problem was introduced in
commit 13d5a6, so it is not present in libvirt versions prior to
0.9.9. Earlier versions would return failure in certain cases even
though the the device object was removed/deleted, but the removal and
deletion operations would always both happen or neither.

It will be used in a different file in an upcoming patch.

There are special stub versions of all public functions in this file
that are compiled when either libnl isn't available or the platform
isn't linux. Each of these functions had two almost identical message,
differing only in the function name included in the message. Since log
messages already contain the function name, we can just define a const
char* with the common part of the string, and use that same string for
all the log messages.

Also, rather than doing #if defined ... #else ... #endif *inside the
error log macro invocation*, this patch does #if defined ... just
once, using it to decide which single string to define. This turns the
error log in each function from 6 lines, to 1 line.

OOM conditions silently returned failure.

This patch will allow OpenFlow controllers to identify which interface
belongs to a particular VM by using the Domain UUID.

ovs-vsctl get Interface vnet0 external_ids
{attached-mac="52:54:00:8C:55:2C", iface-id="83ce45d6-3639-096e-ab3c-21f66a05f7fa", iface-status=active, vm-id="142a90a7-0acc-ab92-511c-586f12da8851"}

V2 changes:
Replaced vm-uuid with vm-id. There was a discussion in Open vSwitch
mailinglist that we should stick with the same DB key postfixes for the
sake of consistency (e.g iface-id, vm-id ...).

The indentation on the final lines of the function was off by four
spaces, making me wonder for a second if there was something
missing. (There wasn't.)

Absence of this stub function caused a build failure on mingw32.

but was too limited.  In particular, Guannan Ren reported:

The schema files contained duplicate data types that can be shared from
the basictypes.rng file.

If we need to virFork() to check assess() under different
UID+GID we need to translate returned status via WEXITSTATUS().
Otherwise, we may return values greater than 255 which is
obviously wrong.
