For systems without a PCI bus, attaching a SCSI controller fails:

  [root@xxxxxxxx ~]# cat controller.xml
  <controller type='scsi' model='virtio-scsi' index='0' />
  [root@xxxxxxxx ~]# virsh attach-device guest01 controller.xml
  error: Failed to attach device from controller.xml
  error: XML error: No PCI buses available

A similar problem occurs with the detach of a controller:

  [root@xxxxxxxx ~]# virsh detach-device guest01 controller.xml
  error: Failed to detach device from controller.xml
  error: operation failed: controller scsi:0 not found

The qemuDomainXXtachPciControllerDevice routines made assumptions
that any caller had a PCI bus.  These routines now selectively calls
PCI functions where necessary, and assigns the device information
type to one appropriate for the bus in use.

For attach/detach of controller devices, we rename the functions to
remove 'PCI' from their title.  The actual separation of PCI-specific
operations will be handled in the next patch.

It makes no sense to go forward to get the parent host number of a

These changes allow the correct virtio-blk-device and virtio-net-device
devices to be used for the 'virt' machine type for armv7 rather than the
PCI virtio devices.

A test case was added to qemuxml2argvtest for this change.

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

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'

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).

Added a macro similar to the GLib's GLIB_CHECK_VERSION so that one can
simply do something like:

 #if LIBVIR_CHECK_VERSION(1,1,3)
   /* Call function here that appeared in 1.1.3 and newer */
   virSomeNewFunction();
 #endif

Without a 'return 0' in the stub lxcStartFuse() method, the
compiler warns:

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.

This allows its error messages to be more specific.

Introduced by 7b4a6304.

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
