74951eadef storage backend: Add RBD (RADOS Block Device) support
This patch adds support for a new storage backend with RBD support.

RBD is the RADOS Block Device and is part of the Ceph distributed storage
system.

It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.

To function this backend relies on librbd and librados being present on the
local system.

The backend also supports Cephx authentication for safe authentication with
the Ceph cluster.

For storing credentials it uses the built-in secret mechanism of libvirt.

2cb0899eec Fix potential events deadlock when unref'ing virConnectPtr
When the last reference to a virConnectPtr is released by
libvirtd, it was possible for a deadlock to occur in the
virDomainEventState functions. The virDomainEventStatePtr
holds a reference on virConnectPtr for each registered
callback. When removing a callback, the virUnrefConnect
function is run. If this causes the last reference on the
virConnectPtr to be released, then virReleaseConnect can
be run, which in turns calls qemudClose. This function has
a call to virDomainEventStateDeregisterConn which is intended
to remove all callbacks associated with the virConnectPtr
instance. This will try to grab a lock on virDomainEventState
but this lock is already held. Deadlock ensues

Thread 1 (Thread 0x7fcbb526a840 (LWP 23185)):

Since each callback associated with a virConnectPtr holds a
reference on virConnectPtr, it is impossible for the qemudClose
method to be invoked while any callbacks are still registered.
Thus the call to virDomainEventStateDeregisterConn must in fact
be a no-op. Thus it is possible to just remove all trace of
virDomainEventStateDeregisterConn and avoid the deadlock.

a3f3ab4c9c nwfilter: Add support for ipset
This patch adds support for the recent ipset iptables extension
to libvirt's nwfilter subsystem. Ipset allows to maintain 'sets'
of IP addresses, ports and other packet parameters and allows for
faster lookup (in the order of O(1) vs. O(n)) and rule evaluation
to achieve higher throughput than what can be achieved with
individual iptables rules.

On the command line iptables supports ipset using

iptables ... -m set --match-set <ipset name> <flags> -j ...

where 'ipset name' is the name of a previously created ipset and
flags is a comma-separated list of up to 6 flags. Flags use 'src' and 'dst'
for selecting IP addresses, ports etc. from the source or
destination part of a packet. So a concrete example may look like this:

iptables -A INPUT -m set --match-set test src,src -j ACCEPT

Since ipset management is quite complex, the idea was to leave ipset 
management outside of libvirt but still allow users to reference an ipset.
The user would have to make sure the ipset is available once the VM is
started so that the iptables rule(s) referencing the ipset can be created.

Using XML to describe an ipset in an nwfilter rule would then look as
follows:

  <rule action='accept' direction='in'>
    <all ipset='test' ipsetflags='src,src'/>
  </rule>

The two parameters on the command line are also the two distinct XML attributes
'ipset' and 'ipsetflags'.

FYI: Here is the man page for ipset:

https://ipset.netfilter.org/ipset.man.html

e8314e78f9 build: fix virnetlink on glibc 2.11
We were being lazy - virnetlink.c was getting uint32_t as a
side-effect from glibc 2.14's <unistd.h>, but older glibc 2.11
does not provide uint32_t from <unistd.h>.  In fact, POSIX states
that <unistd.h> need only provide intptr_t, not all of <stdint.h>,
so the bug really is ours.  Reported by Jonathan Alescio.

fe0aac0503 Adds support to param 'vcpu_time' in qemu_driver.
This involves setting the cpuacct cgroup to a per-vcpu granularity,
as well as summing the each vcpu accounting into a common array.
Now that we are reading more than one cgroup file, we double-check
that cpus weren't hot-plugged between reads to invalidate our
summing.

d29a7aaa1a Add a new param 'vcpu_time' to virDomainGetCPUStats
Currently virDomainGetCPUStats gets total cpu usage, which consists
of:

  1. vcpu usage: the physical cpu time consumed by virtual cpu(s) of
     domain
  2. hypervisor: `total cpu usage' - `vcpu usage'

The param 'vcpu_time' is for getting vcpu usages.

2f5fdc886e qemu: Rollback on used USB devices
One of our latest USB device handling patches
05abd1507d introduced a regression.
That is, we first create a temporary list of all USB devices that
are to be used by domain just starting up. Then we iterate over and
check if a device from the list is in the global list of currently
assigned devices (activeUsbHostdevs). If not, we add it there and
continue with next iteration then. But if a device from temporary
list is either taken already or adding to the activeUsbHostdevs fails,
we remove all devices in temp list from the activeUsbHostdevs list.
Therefore, if a device is already taken we remove it from
activeUsbHostdevs even if we should not. Thus, next time we allow
the device to be assigned to another domain.

a8c0b2fed0 Remount cgroups controllers after setting up new /sys in LXC
Normal practice is for cgroups controllers to be mounted at
/sys/fs/cgroup. When setting up a container, /sys is mounted
with a new sysfs instance, thus we must re-mount all the
cgroups controllers. The complexity is that we must mount
them in the same layout as the host OS. ie if 'cpu' and 'cpuacct'
were mounted at the same location in the host we must preserve
this in the container. Also if any controllers are co-located
we must setup symlinks from the individual controller name to
the co-located mount-point

e8639920ac Mount fresh instance of sysfs/selinux in LXC
Currently to make sysfs readonly, we remount the existing
instance and then bind it readonly. Unfortunately this means
sysfs is still showing device objects wrt the host OS namespace.
We need it to reflect the container namespace, so we must mount
a completely new instance of it. Do the same for selinuxfs since
there is no benefit to bind mounting & this lets us simplify
the code.

10d9038b74 nodeinfo: Get the correct CPU number on AMD Magny Cours platform
"Instead of developing one CPU with 12 cores, the Magny Cours is
actually two 6 core “Bulldozer” CPUs combined in to one package"

I.e, each package has two NUMA nodes, and the two numa nodes share
the same core ID set (0-6), which means parsing the cores number
from sysfs doesn't work in this case.

And the wrong CPU number could cause three problems for libvirt:

1) performance lost

  A domain without "cpuset" or "placement='auto'" (to drive numad)
specified will be only pinned to part of the CPUs.

2) domain can be started

  If a domain uses numad, and the advisory nodeset returned from
numad contains node which exceeds the range of wrong total CPU
number. The domain will fail to start, as the bitmask passed to
sched_setaffinity could be fully filled with zero.

3) wrong CPU number affects lots of stuffs.

  E.g. for command "virsh vcpuinfo", "virsh vcpupin", it will always
output with the truncated CPU list.

For more details:

https://www.redhat.com/archives/libvir-list/2012-May/msg00607.html

This patch is to fix the problem by parsing /proc/cpuinfo to get
the value of field "cpu cores", and use it as nodeinfo->cores if
it's greater than the cores number from sysfs.

2b366b46dc nodeinfo: avoid probing host filesystem during test
We had previously weakened our nodeinfotest in order to ignore parsed
node values, because the parse function was mistakenly relying on
host files.  A better fix is to avoid using the numactl library, but
to instead parse the same files that numactl would read, all while
allowing the files to be relative to our choice of directory.

* src/nodeinfo.c (CPU_SYS_PATH, NODE_SYS_PATH): Replace with...
(SYSFS_SYSTEM_PATH): ...parent directory.
(linuxNodeInfoCPUPopulate): Check NUMA nodes from requested
directory (by inlining numactl code).
(nodeGetCPUmap, nodeGetMemoryStats): Adjust macro use.
* tests/nodeinfotest.c (linuxTestCompareFiles, linuxTestNodeInfo):
Update test to match.

88f12a3665 nodeinfo: drop static variable
We were wasting time to malloc a copy of a constant string, then
copy it into static storage, for every call to nodeGetInfo.  At
least we were lucky that it was a constant source, and thus not
subject to even worse issues with one thread clobbering the static
storage while another was using it.  This gets rid of the waste,
by passing the string through the stack instead, as well as renaming
internal functions to better match our conventions.

* src/nodeinfo.c (sysfs_path): Delete.
(get_cpu_value, count_thread_siblings, parse_socket): Add
parameter, and rename...
(virNodeGetCpuValue, virNodeCountThreadSiblings)
(virNodeParseSocket): ... into a common namespace.
(cpu_online, parse_core): Inline into callers.
(linuxNodeInfoCPUPopulate): Update caller.
(nodeGetInfo): Drop a useless malloc.

5f89c86004 build: really silence the 32-bit warning
Commit cdce2f42d tried to silence a compiler warning on 32-bit builds,
but the gcc shipped with RHEL 5 is old enough that the type conversion
via multiplication by 1 was insufficient for the task.

* src/qemu/qemu_monitor.c (qemuMonitorBlockJob): Previous attempt
didn't get past all gcc versions.
