For a while we're have random failures of 'securityselinuxtest'
which were not at all reproducible. Fortunately we finally
caught a failure with VIR_TEST_DEBUG=1 enabled. This revealed
TEST: securityselinuxtest
1) GenLabel "dynamic unconfined, s0, c0.c1023" ... OK
2) GenLabel "dynamic unconfined, s0, c0.c1023" ... OK

7) GenLabel "dynamic virtd, missing range" ... Category two 1024 is out of range 0-1023

And sure enough we had an off-by-1 in the MCS range code when
the current process has no range set. The test suite randomly
allocates 2 categories from 0->1024 so the chances of hitting
this in the test suite were slim indeed :-)

RHEL-6's rpmbuild wipes the docdir for a (sub-)package if any %doc
directives are present, prior to copying in the marked documentation.
This means we can't prepopulate this directory with the HTML
documentation during the %install phase.
Instead, move the HTML documentation to a temporary directory during
%install and mark the contents of this temporary directory with %doc.
This fixes a build regression introduced in

On the domain startup, this function is called to dump some info about
the CPUs. At the beginning of the function we check if we aren't running
older qemu which is not exposing the CPUs via 'qom-list'. However, we
are not checking for even older qemus, which throw 'CommandNotFound'
error.

This patch shuts up the following warning of clang
on Mac OS X:
virsh.c:2761:22: error: assigning to 'char *' from 'const char [6]' discards qualifiers
[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
rl_readline_name = "virsh";
^ ~~~~~~~
The warning happens because rl_readline_name on Mac OS X comes
from an old readline header that still uses 'char *', while it
is 'const char *' in readline 4.2 (April 2001) and newer.
Tested on Mac OS X 10.8.5 (clang-500.2.75) and Fedora 19 (gcc 4.8.1).

/* Call function here that appeared in 1.1.3 and newer */
virSomeNewFunction();

The glibc setxid is supposed to be async signal safe, but
libc developers confirm that it is not. This causes a problem
when libvirt_lxc starts the FUSE thread and then runs clone()
to start the container. If the clone() was done before the
FUSE thread has completely started up, then the container
will hang in setxid after clone().
The fix is to avoid creating any threads until after the
container has been clone()'d. By avoiding any threads in
the parent, the child is no longer required to run in an
async signal safe context, and we thus avoid the glibc
bug.

Report the error in virPortAllocatorAcquire instead
of doing it in every caller.
The error contains the port range name instead of the intended
use for the port, e.g.:
Unable to find an unused port in range 'display' (65534-65535)
instead of:
Unable to find an unused port for SPICE
This also adds error reporting when the QEMU driver could not
find an unused port for VNC, VNC WebSockets or NBD migration.
The connection pointer in the closeCallback data was never
initialized, making the unref in remoteClientCloseFunc a no-op.
This fixes the following leak in virsh when the daemon closes
the connection unexpectedly:

So far qemuSetupHostdevCGroup was called very early during hotplug, even
before we knew the device we were about to hotplug was actually
available. By calling the function later, we make sure QEMU won't be
allowed to access devices used by other domains.
Another important effect of this change is that hopluging USB devices
specified by vendor and product (but not by their USB address) works
again. This was broken since v1.0.5-171-g7d763ac, when the call to
qemuFindHostdevUSBDevice was moved after the call to
qemuSetupHostdevCGroup, which then used an uninitialized USB address.

The aim of virObject refing and urefing is to tell where the object is
to be used and when is no longer needed. Hence any object shouldn't be
used after it has been unrefed, as we might be the last to hold the
reference. The better way is to call virObjectUnref() *after* the last
object usage. In this specific case, the monitor EOF handler was called
after the qemuMonitorIO called virObjectUnref. Not only that @mon was
disposed (which is not used in the handler anyway) but the @mon->vm
which is causing a SIGSEGV:

In the qemuProcessReconnectHelper() a new thread that does all the
interesting work is spawned. The rationale is to not block the daemon
startup process in case of unresponsive qemu. However, the thread
handler is a local variable which gets lost once the control goes out of
scope. Hence the thread gets leaked. We can avoid this if the thread
isn't made joinable.

While trying to compare netfs against my new gluster pool, I
discovered two things:
virt-xml-validate chokes on valid xml produced by 'virsh pool-dumpxml'
[yet another reason that ALL patches that add new xml should be adding
corresponding tests]
When using glusterfs FUSE mounts, you cannot access a subdirectory
of a gluster volume. The recommended workaround in the gluster
community is to mount the volume to an intermediate location, then
bind-mount the desired subdirectory to the final location. Maybe
we should teach libvirt to do bind-mounting, but for now I chose to
just document the limitation.

The QOM path in qemu that contains the CPUID registers of a running VM
may not be present (introduced in QEMU 1.5).
Since commit d94b781771 we have a regression with QEMU that don't
support reporting of the CPUID register state via the monitor as the
process startup code expects the path to exist.
This patch adds code that checks with the monitor if the requested path
already exists and uses it only in this case.
