This file contains only a single function, detect_scsi_host_caps(),
which is declared in node_device_driver.h and called from both the hal
and udev backends. Other things common to the hal and udev drivers
can be placed in that file though. As a prelude to adding further
functions, this patch renames the existing function to something
closer in line with other internal libvirt function names
(nodeDeviceSysfsGetSCSIHostCaps()), and puts the declarations into a
separate .h file.
We will want to use synchronous block jobs from qemu_migration as well,
so split this function out into a new source file.

Throughout the code, we have several places need to construct a path
somewhere in /sys/class/net/... They are not consistent and nearly
each code piece invents its own way how to do it. So unify this by:
1) use virNetDevSysfsFile() wherever possible
2) At least use common macro SYSFS_NET_DIR declared in virnetdev.h at
the rest of places which can't go with 1)

libvirt's compile will try to create the symlink for cpu_map.xml before

Each thread can use a thread local variable to keep the name of a job
which is currently running in the job.
The virThreadJobSetWorker API is supposed to be called once by any
thread which is used as a worker, i.e., it is waiting in a pool, woken
up to do a job, and returned back to the pool.
The virThreadJobSet/virThreadJobClear APIs are to be called at the
beginning/end of each job.

For a while now there are two places that gather information about NUMA
related guest configuration. While the XML can't be changed we can at
least store the data in one place in the definition.
Rename the numatune_conf.[ch] files to numa_conf as later patches will
move the rest of the definitions from the cpu definition to this one.
Not all files we want to find using virFileFindResource{,Full} are
generated when libvirt is built, some of them (such as RNG schemas) are
distributed with sources. The current API was not able to find source
files if libvirt was built in VPATH.
Both RNG schemas and cpu_map.xml are distributed in source tarball.

For stateless, client side drivers, it is never correct to
probe for secondary drivers. It is only ever appropriate to
use the secondary driver that is associated with the
hypervisor in question. As a result the ESX & HyperV drivers
have both been forced to do hacks where they register no-op
drivers for the ones they don't implement.
For stateful, server side drivers, we always just want to
use the same built-in shared driver. The exception is
virtualbox which is really a stateless driver and so wants
to use its own server side secondary drivers. To deal with
this virtualbox has to be built as 3 separate loadable
modules to allow registration to work in the right order.
This can all be simplified by introducing a new struct
recording the precise set of secondary drivers each
hypervisor driver wants
struct _virConnectDriver {
virHypervisorDriverPtr hypervisorDriver;
virInterfaceDriverPtr interfaceDriver;
virNetworkDriverPtr networkDriver;
virNodeDeviceDriverPtr nodeDeviceDriver;
virNWFilterDriverPtr nwfilterDriver;
virSecretDriverPtr secretDriver;
virStorageDriverPtr storageDriver;
};
Instead of registering the hypervisor driver, we now
just register a virConnectDriver instead. This allows
us to remove all probing of secondary drivers. Once we
have chosen the primary driver, we immediately know the
correct secondary drivers to use.

A bunch of code is wrapped in #if WITH_LIBVIRTD in order to
enable the virStateDriver to be disabled when libvirtd is not
built. Disabling this code doesn't have any real functional
benefit beyond removing 1 pointer from the virConnectPtr struct,
while having a cost of many more conditionals.

Moving code for parsing and formatting network routes to
networkcommon_conf helps reusing those routes for domains. The route
definition has been hidden to help reducing the number of unnecessary
checks in the format function.
Introduce a parser/formatter for the xl config format. Since the
deprecation of xm/xend, the VM config file format has diverged as
new features are added to libxl. This patch adds support for parsing
and formating the xl config format. It supports the existing xm config
format, plus adds support for spice graphics and xl disk config syntax.
Disk config is specified a bit differently in xl as compared to xm. In
xl, disk config consists of comma-separated positional parameters and
keyword/value pairs separated by commas. Positional parameters are
specified as follows
target, format, vdev, access
Supported keys for key=value options are
devtype, backendtype
The positional paramters can also be specified in key/value form. For
example the following xl disk config are equivalent
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
See $xen_sources/docs/misc/xl-disk-configuration.txt for more details.
xl disk config is parsed with the help of xlu_disk_parse() from
libxlutil, libxl's utility library. Although the library exists
in all Xen versions supported by the libxl virt driver, only
recently has the corresponding header file been included. A check
for the header is done in configure.ac. If not found, xlu_disk_parse()
is declared externally.

Well, the parallel build doesn't work as there are not dependencies
set correctly. When running 'make -j' I see this error:
make[2]: Entering directory '/home/zippy/work/libvirt/libvirt.git/src'

make[2]: *** No rule to make target 'xenconfig/xen_xl_disk.h', needed by 'all'. Stop.

The fix is to correctly set dependencies by letting make know that .c
and .h are to be generated from .l. Moreover, the section is moved
closer to the other section which uses it.

Ever since commit 2c78051 split out a helper library for the sake of
changing CFLAGS, a VPATH build with xenconfig enabled has failed:
CC xenconfig/libvirt_xenxldiskparser_la-xen_xl_disk.lo
../../src/xenconfig/xen_xl_disk.l:37:21: fatal error: xen_xl.h: No such file or directory
# include "xen_xl.h"
^
compilation terminated.
Makefile:9462: recipe for target 'xenconfig/libvirt_xenxldiskparser_la-xen_xl_disk.lo' failed
The solution is to tell the build to look for xen_xl.h relative
to $(srcdir), since we keep that file under version control.
[Not fixed here - the raw use of -Wno-unused-parameter in CFLAGS
is NOT portable; ideally, we should be doing a configure test
and only supplying that argument when we know the compiler supports
-Wunused-parameter; but that's a patch for another day]
[Not fixed here - there are still issues with parallel builds hitting
a race between generating the files and trying to compile/distribute
them]

Introduce a Xen xl parser
This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below
target, format, vdev, access
The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as
devtype, backend, backendtype, script, direct-io-safe,
The positional paramters can also be specified in key/value form
for example
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
are interpleted to one config.
In xm format, the above diskspec would be written as
phy:/dev/vg/guest-volume,hda,w
The disk parser is based on the same parser used successfully by
the Xen project for several years now. Ian Jackson authored the
scanner, which is used by this commit with mimimal changes. Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.

Currently, MAC registration occurs during device creation, which is
early enough that, during live migration, you end up with duplicate
MAC addresses on still-running source and target devices, even though
the target device isn't actually being used yet.
This patch proposes to defer MAC registration until right before
the guest can actually use the device -- In other words, right
before starting guest CPUs.

This patch rewrites the following functions
*vboxStorageOpen
*vboxStorageClose
*vboxConnectNumOfStoragePools
*vboxConnectListStoragePools
*vboxStoragePoolLookupByName
These functions do not call any vbox API, so I directly move it
from vbox_tmpl.c to vbox_storage.c
A small improvement is made on vboxConnectListStoragePools.
The if condition nnames == 1 is modified to nnames > 0. So if the
caller put more than one slot to get active storage pools, the new
function will return exactly one, while the old one would only
return 0.
The recently added driver-*.h files were not listed in the
Makefile.am causing them to be missed when creating dists.

This allows to implement libvirt functions that use streams, such as
virDoaminScreenshot, without the need to store the downloaded data in
a temporary file first. The stream driver directly interacts with
libcurl to send and receive data.
The driver uses the libcurl multi interface that allows to do a transfer
in multiple curl_multi_perform() calls. The easy interface would do the
whole transfer in a single curl_easy_perform() call. This doesn't work
with the libvirt stream API that is driven by multiple calls to the
virStreamSend() and virStreamRecv() functions.
The curl_multi_wait() function is used to do blocking operations. But it
was added in libcurl 7.28.0. For older versions it is emulated using the
socket callback of the multi interface.
The current driver only supports blocking operations. There is already
some code in place for non-blocking mode but it is not complete.
After 87dea4fcf one can observe a build failure:
./autogen.sh --system --without-driver-modules && make

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