7e3205cd10 Move XenAPI driver to correct spec file section
The XenAPI driver works like the ESX and PHyp driver by using its
own HTTPS based remote protocol.

b369114de6 numatune: Add tests for numatune XML
Only add tests for qemuxmlargvtest.c, as there is no qemu command line
for numatune XML, just want to make sure the XML could be validated
well.

a6f5c9b600 numatune: Support NUMA memory tuning in qemu driver
Implemented as setting NUMA policy between fork and exec as a hook,
using libnuma. Only support memory tuning on domain process currently.

For the nodemask out of range, will report soft warning instead of
hard error in libvirt layer. (Kernel will be silent as long as one
of set bit in the nodemask is valid on the host. E.g. For a host
has two NUMA nodes, kernel will be silent for nodemask "01010101").
So, soft warning is the only thing libvirt can do, as one might want
to specify the numa policy prior to a node that doesn't exist yet,
however, it may come as hotplug soon.

34e3ec90f6 build: fix building error when building without libvirtd
When building libvirt without libvirtd, we will receive the following error
message:

make[3]: Entering directory `/home/wency/rpmbuild/BUILD/libvirt-0.9.2/tools'
  CC     virsh-virsh.o

./src/.libs/libvirt.so: undefined reference to `numa_available'
./src/.libs/libvirt.so: undefined reference to `numa_max_node'
collect2: ld returned 1 exit status

The reason is that: we check numactl only when building qemu driver, and qemu
driver will not be built when bulding without libvirtd. So with_numactl's
value is check and we will not link libnuma.so.

In the other function, we call numa_available() and numa_max_node() only
when HAVE_NUMACTL is 1. We should do the same check in the function nodeGetMemoryStats().

b9757fea30 apparmor: implement AppArmorSetFDLabel()
During a savevm operation, libvirt will now use fd migration if qemu
supports it. When the AppArmor driver is enabled, AppArmorSetFDLabel()
is used but since this function simply returns '0', the dynamic AppArmor
profile is not updated and AppArmor blocks access to the save file. This
patch implements AppArmorSetFDLabel() to get the pathname of the file by
resolving the fd symlink in /proc, and then gives that pathname to
reload_profile(), which fixes 'virsh save' when AppArmor is enabled.

a81822063d Fix errno return in safezero()
Most of the safezero() implementations return -1 on error,
setting errno. The safezero() impl using posix_fallocate()
though returned a positive errno value on error (due to
the unusual API contract of posix_fallocate() compared to
most syscall APIs).

  errno on error.

c3068d4d23 qemu: Translate boot config into bootindex if possible
Prefer bootindex=N option for -device over the old way -boot ORDER
possibly accompanied with boot=on option for -drive. This gives us full
control over which device will actually be used for booting guest OS.
Moreover, if qemu doesn't support boot=on, this is the only way to boot
of certain disks in some configurations (such as virtio disks when used
together IDE disks) without transforming domain XML to use per device
boot elements.

98bfdff12c spice: add <clipboard copypaste='yes|no'> option
From a security pov copy and paste between the guest and the client is not
always desirable. So we need to be able to enable/disable this. The best place
to do this from an administration pov is on the hypervisor, so the qemu cmdline
is getting a spice disable-copy-paste option, see bug 693645. Example qemu
invocation:
qemu -spice port=5932,disable-ticketing,disable-copy-paste
