The arguments passed to the thread function must be allocated on

In such a case, it is possible that the area of stack where the

As virsh help supports both command and command group now,
update "cmdHelp" to print consite help, (this patch is
increment of "78290527").

And also remove redundant empty line in "vshUsage".

Use macvtap specific functions depending on WITH_MACVTAP.

Use #if instead of #ifdef to check for WITH_MACVTAP, because
WITH_MACVTAP is always defined with value 0 or 1.

Also export virVMOperationType{To|From}String unconditional,
because they are used unconditional in the domain config code.

The output was previously:

    -c | --connect <uri>    hypervisor connection URI
    -r | --readonly         connect readonly
    -d | --debug <num>      debug level [0-5]

    -q | --quiet            quiet mode
    -t | --timing           print timing information
    -l | --log <file>       output logging to file
    -v | --version[=short]  program version

    -V | --version=long     version and full options

(note the blank line between the --version types)

This patch removes the extra blank line.

When dumping a domain, it's reasonable to save dump-file in raw format
if dump format is misconfigured or the corresponding compress program
is not available rather then fail dumping.

Change the virsh help out. The new output of "virsh help" and
"virsh --help" will be like:

 Secret (help keyword 'secret'):
    secret-define                  define or modify a secret from an XML file
    secret-dumpxml                 secret attributes in XML
    secret-set-value               set a secret value
    secret-get-value               Output a secret value
    secret-undefine                undefine a secret
    secret-list                    list secrets

 Snapshot (help keyword 'snapshot'):
    snapshot-create                Create a snapshot
    snapshot-current               Get the current snapshot
    snapshot-delete                Delete a domain snapshot
    snapshot-dumpxml               Dump XML for a domain snapshot
    snapshot-list                  List snapshots for a domain
    snapshot-revert                Revert a domain to a snapshot

Also support output help information of specified command group, e.g.

% ./tools/virsh help "Network Filter"
 Network Filter (help keyword 'filter'):
    nwfilter-define                define or update a network filter from an XML file
    nwfilter-undefine              undefine a network filter
    nwfilter-dumpxml               network filter information in XML
    nwfilter-list                  list network filters
    nwfilter-edit                  edit XML configuration for a network filter

Each group has a help keyword, e.g.

% ./tools/virsh help filter
 Network Filter (help keyword 'filter'):
    nwfilter-define                define or update a network filter from an XML file
    nwfilter-undefine              undefine a network filter
    nwfilter-dumpxml               network filter information in XML
    nwfilter-list                  list network filters
    nwfilter-edit                  edit XML configuration for a network filter

This patch introduces the usage of the pre-associate state of the IEEE 802.1Qbg standard on incoming VM migration on the target host. It is in response to bugzilla entry 632750.

https://bugzilla.redhat.com/show_bug.cgi?id=632750

For being able to differentiate the exact reason as to why a macvtap device is being created, either due to a VM creation or an incoming VM migration, I needed to pass that reason as a parameter from wherever qemudStartVMDaemon is being called in order to determine whether to send an ASSOCIATE (VM creation) or a PRE-ASSOCIATE (incoming VM migration) towards lldpad.

I am also fixing a problem with the virsh domainxml-to-native call on the way.

Gerhard successfully tested the patch with a recent blade network 802.1Qbg-compliant switch.

The patch should not have any side-effects on the 802.1Qbh support in libvirt, but Roopa (cc'ed) may want to verify this.

Don't overwrite errors during domain creation/definition to ease
tracking down problems.

We currently use the next free veid although there's one given in the
domain xml. This currently breaks defining new domains since vmdef->name
and veid don't match leading to the following error later on:

    error: Failed to define domain from 110.xml
    error: internal error Could not set UUID

Since silently ignoring vmdef->name is not nice respect it instead. We
avoid veid collisions in the upper levels already.

This reverts commit

 Log all errors at level INFO to stop polluting syslog
 04bd0360.

and makes virRaiseErrorFull() log errors at debug priority
when called from inside libvirtd. This stops libvirtd from
polluting it's own log with client errors at error priority
that'll be reported and logged on the client side anyway.

When we set migrate_speed by json, we receive the following
error message:
libvirtError: internal error unable to execute QEMU command
'migrate_set_speed': Invalid parameter type, expected: number

The reason is that: the arguments of migrate_set_speed
by json is json number, not json string.

The dominfo.py example script has a bogus check for /proc/xen
existing. The default connection cannot be assumed to be Xen
any more

* examples/python/dominfo.py: Remove check for Xen

The nodeinfo structure includes

    nodes   : the number of NUMA cell, 1 for uniform mem access
    sockets : number of CPU socket per node
    cores   : number of core per socket
    threads : number of threads per core

which does not work well for NUMA topologies where each node does not
consist of integral number of CPU sockets.

We also have VIR_NODEINFO_MAXCPUS macro in public libvirt.h which
computes maximum number of CPUs as (nodes * sockets * cores * threads).

As a result, we can't just change sockets to report total number of
sockets instead of sockets per node. This would probably be the easiest
since I doubt anyone is using the field directly. But because of the
macro, some apps might be using sockets indirectly.

This patch leaves sockets to be the number of CPU sockets per node (and
fixes qemu driver to comply with this) on machines where sockets can be
divided by nodes. If we can't divide sockets by nodes, we behave as if
there was just one NUMA node containing all sockets. Apps interested in
NUMA should consult capabilities XML, which is what they probably do
anyway.

This way, the only case in which apps that care about NUMA may break is
on machines with funky NUMA topology. And there is a chance libvirt
wasn't able to start any guests on those machines anyway (although it
depends on the topology, total number of CPUs and kernel version).
Nothing changes at all for apps that don't care about NUMA.

security_context_t happens to be a typedef for char*, and happens to
begin with a string usable as a raw context string.  But in reality,
it is an opaque type that may or may not have additional information
after the first NUL byte, where that additional information can
include pointers that can only be freed via freecon().

Proof is from this valgrind run of daemon/libvirtd:

==6028== 839,169 (40 direct, 839,129 indirect) bytes in 1 blocks are definitely lost in loss record 274 of 274

virConnectClose calls virUnrefConnect which in turn closes
all open drivers when the refcount of that connection dropped
to zero. This works fine when you free all other objects that
hold a ref to the connection before you close it, because in
this case virUnrefConnect is the one that removes the last
ref to the connection.

But it doesn't work when you close the connection first before
freeing the other objects. This is because the other virUnref*
functions call virReleaseConnect when they detect that the
connection's refcount dropped to zero. In this case another
virUnref* function (different from virUnrefConnect) removes the
last ref to the connection. This results in not closing the
open drivers and leaking things that should have been cleaned
up in the driver close functions.

To fix this move the driver close calls to virReleaseConnect.

Except LXC and UML driver, implementations of all other drivers
simply return 0, because these drivers doesn't have config both
in memory and on disk, no need to track if the domain of these
drivers updated or not.
