9cf6dd00ce configure: improve misleading libnl3-devel missing error message
When building libvirt from source with netcf-devel installed, the
configure script reports error "libnl-devel >=3.0 is required for
macvtap support", while actually libnl3-devel is required.

b4022de33a Makefile: Fix build without driver modules
After 87dea4fcf one can observe a build failure:

reference to `vboxGetNetworkDriver'
collect2: error: ld returned 1 exit status
make[3]: *** [libvirtd] Error 1

The problem is that when building without driver modules the VBOX
network driver is not linked into the the VBOX driver.

87dea4fcff vbox: New network driver
This patch seperate the domain driver and the network driver.

libvirt_driver_vbox_impl.la has been linked in the network driver.
So that the version specified codes in vbox_V*.c would only be
compiled once.

The vboxGetNetworkDriver provides a simple interface to get vbox
network driver.

fac5d061ed vbox: Interfaces for register per parties
The patch dbb4cbf532 by Michal has splited the vbox driver into
three parties. This modification brings a more suitable interface
to the previous patch.

The new function vboxGetDriver is introduced to get the
corresponding vbox domain driver directly thought the vbox version.

Functions like vboxGetNetworkDriver and vboxGetStorageDriver
will be introduced after rewriting it's drivers.

This patch, by the way, fixed the align problem for vbox in

4882618ed1 qemu: use systemd's TerminateMachine to kill all processes
If we don't properly clean up all processes in the
machine-<vmname>.scope systemd won't remove the cgroup and subsequent vm
starts fail with

  'CreateMachine: File exists'

Additional processes can e.g. be added via

  echo $PID > /sys/fs/cgroup/systemd/machine.slice/machine-${VMNAME}.scope/tasks

but there are other cases like

  http://bugs.debian.org/761521

Invoke TerminateMachine to be on the safe side since systemd tracks the
cgroup anyway. This is a noop if all processes have terminated already.

7557ddf8be qemu: bulk stats: add block allocation information
Management software wants to be able to allocate disk space on demand.
To support this they need keep track of the space occupation of the
block device.  This information is reported by qemu as part of block
stats.

This patch extend the block information in the bulk stats with the
allocation information.

To keep the same behaviour a helper is extracted from
qemuMonitorJSONGetBlockExtent in order to get per-device allocation
information.

f53bb1af90 Also filter out non-migratable features out of host-passthrough
Commit de0aeaf filtered them out from the host-model features,
to allow host-model to be migratable by default.

Even though they are not passed to QEMU for host-passthrough,
(and not enabled by default) filter them out too
so the user does not think the domain has them.

ec5f817f2e Don't verify CPU features with host-passthrough
Commit fba6bc4 introduced the non-migratable invtsc feature,
breaking save/migration with host-model and host-passthrough.

On hosts with this feature present it was automatically included
in the CPU definition, regardless of QEMU support.

Commit de0aeaf stopped including it by default for host-model,
but failed to fix host-passthrough.

This commit ignores checking of CPU features with host-passthrough,
since we don't pass them to QEMU (only -cpu host is passed),
allowing domains using host-passthrough that were saved with
the broken version of libvirtd to be restored.

0778c0be8d Rename tunable event constants
For the new VIR_DOMAIN_EVENT_ID_TUNABLE event we have a bunch of
constants added

   VIR_DOMAIN_EVENT_CPUTUNE_<blah>
   VIR_DOMAIN_EVENT_BLKDEVIOTUNE_<blah>

This naming convention is bad for two reasons

  - There is no common prefix unique for the events to both
    relate them, and distinguish them from other event
    constants

  - The values associated with the constants were chosen
    to match the names used with virConnectGetAllDomainStats
    so having EVENT in the constant name is not applicable in
    that respect

This patch proposes renaming the constants to

    VIR_DOMAIN_TUNABLE_CPU_<blah>
    VIR_DOMAIN_TUNABLE_BLKDEV_<blah>

ie, given them a common VIR_DOMAIN_TUNABLE prefix.

c99f66ac4c lxc_monitor_protocol: Redefine xdr_uint64_t if needed
https://bugzilla.redhat.com/show_bug.cgi?id=993411

On some systems (using libtirpc instead of glibc's

xdr_u_int64_t. This makes compilation fail then:

libvirt_lxc-lxc_monitor_protocol.o: In function `xdr_virLXCMonitorInitEventMsg':
/usr/local/src/libvirt/libvirt-1.1.1/src/./lxc/lxc_monitor_protocol.c:31: undefined reference to `xdr_uint64_t'

fe7ef7b112 qemu: Always re-detect backing chain
Since 363e9a68 we track backing chain metadata when creating snapshots
the right way even for the inactive configuration. As we did not yet
update other code paths that modify the backing chain (blockpull) the
newDef backing chain gets out of sync.

After stopping of a VM the new definition gets copied to the next start
one. The new VM then has incorrect backing chain info. This patch
switches the backing chain detector to always purge the existing backing
chain and forces re-detection to avoid this issue until we'll have full
backing chain tracking support.
